Message-ID: <1288801684.27647.1403415697@webmail.messagingengine.com>

Anyone have any experience using Python Tkinter/ttk applications
with Citrix or WTS (Windows Terminal Services)?

Any concerns, gotchas, or workarounds we should be aware of?

I googled this topic [1], [2] and came up with nothing. No news
is good news<g> ... but just checking to make sure.

Thanks,
Malcolm

Subject: [Tkinter-discuss] Possible to stack frames with frame transparency?
 (create widget w/gradient background)
Message-ID: <1288810552.4463.1403440447@webmail.messagingengine.com>

New to Tkinter: Is it possible to stack frames on top of one
another and if so, can frames have transparency?

My goal is to create widgets with gradient backgrounds. I was
hoping I could do this by placing an image in a frame and then
placing an identical sized frame over this image frame. This
on-top frame would contain all my child widgets.

Details: Is it possible to place a frame on top of an image
background? From my reading, the only way to do this appears to
be to use a Canvas as my container (vs. a Frame). The downside to
using a canvas appears to be that Labels do not have transparent
backgrounds so any text I place in such a (canvas based)
container must be placed with Canvas.create_text() vs. laid out
via one of the pack/grid/place layout managers. Am I
understanding this right?

Thank you,
Malcolm

Malcom,

Unless things have changed in recent releases of Tcl/Tk,
what you are tring to do is not possible.

Frames cannot be transparent.

Frames cannot usually be stacked on top of each other.
As you suggest, this might be done via placing them in a canvas,
using the create_window method. But each frame on top
of another totally obscures those below.

To see what can be done, look at my tkinter-based interface,
at: http://www.wagsoft.com/CorpusTool/img/main.jpg

The button "Search" is a canvas totally filled with 3 images
left, centre and right parts of the button. On top of that I then
use create-text to write "Search". I then write it 2 pixels above/left
in a different color to create an embossed look.

I think this could be helpful for you:

http://saveimg.ru/pictures/04-11-10/12d35ff67732239776ca2dfe7a483d30.png

This is tkCairo extension in work. You can find the code in our repository:

http://sk1.svn.sourceforge.net/viewvc/sk1/trunk/subprojects/tkCairo/

tkCairo is modified pycairo project for tk widgetset. So you can use pycairo
docs
as a cairo command reference. Please note we have implemented Linux support
only.
But this extension can be easy adopted for win32.

Concerning tk Frame stacking you can try using place() manager. All tk
widgets are
native windows without WM decorations. So you can apply all toplevel methods
to widgets if they managed by place() manager.

Small addition: tkCairo allows drawing on regular tk Frame widget and you
can pack in this
Frame any other child widget (on screenshot tk Button is packed into such
frame).

Nice! So each of your top buttons (Project, Search, Autocode, etc) is
actually a custom widget based on a canvas containing 3 images (manually
placed via .create_image) and then manually labeled with text via
.create_text)? And your canvas backgroundcolors are set to the
backgroundcolor of their parent frame? If I understand your technique,
you place everything manually vs. using a layout manager like pack/grid?

I noticed your buttons are not all the same width - do you have custom
width centre images or is there a way to horizontally stretch an image?
(I've looked for this capability without success). 

Thanks for sharing your technique and screenshot. The screenshot really
helped me understand what you're saying.

Cheers,
Malcolm

Hi Malcom,

  Full code for these buttons available from:

http://www.wagsoft.com/CTButtonCode.zip

Run demo.py to see 3 buttons.

Buttons change appearance on mouse over and when pressed.

Provide your own image parts to make your own buttons.

Unfortunately the buttons are tied in with other code for theming my
application,
also attached.

Mick

Subject: [Tkinter-discuss] winico icon coordinates
Message-ID: <20101109123157.b66adcde.klappnase@web.de>

Hi all,

I am trying to write a cross-platform tray icon wrapper for Tkinter that
uses tktray on X and winico on windows. It is working fine so far,
however at one point I am stuck with winico. I would like to be able to
pop up a "notification balloon" (or however you want to call this) next
to the tray icon, which works fine on tktray (which has a bbox method
that allows to access the icon's screen coordinates) but I cannot seem to
be able to do the same with winico.
Does anyone have experience with winico, is this possible at all (maybe I
missed something), or maybe is this possible somehow through pywin32 ?

Thanks in advance

Michael

How can I create non-selectable horizontal separator items in a
Listbox, eg. separators equivalent to the Tkinter Menu widget's
.add_separator()? Using chars like dashes and underscores looks
awful.

If this functionality is not possible, does anyone have a
recommendation on a Unicode char similar to an underscore, but

Unless recent versions have a configuration for this
I haven't yet learned, the functionality you're after
requires a custom binding.

unichr(8213)  looks pretty good. I'm not sure if your original desire is
possible, but you could make it non-selectable by binding <<ListboxSelect>>
. You'd do something like this:

1. Is current selection one of the separators?
2. If not, OK
3. If so, change selection to the previous item

If this is an option at all for you, maybe you should consider to use some
third-party extension to Tk. What you want should be fairly easy to set
up with tktreectrl, maybe you can do this with other widgets like
tablelist or even the ttk treeview, too, I haven't used these much
though, so I cannot tell.
If you want to try tktreectrl, the python module comes with a ready to
use multi column listbox class, and you can define custom states and
apply them to individual items and define the item's appearance by state,
just look at the demos and you will probably see te point.

tktreectrl can be found here: http://tktreectrl.sourceforge.net/
and the python wrapper: http://klappnase.bubble.org/TkinterTreectrl/

tablelist: http://www.nemethi.de/
and the python module: http://tkinter.unpy.net/wiki/TableListWrapper

Subject: [Tkinter-discuss] Memory leak with tkinter canvas itemconfigure
Message-ID: <4CDC6F1A.3080804@velseis.com.au>

Hi,

I have an application that configures thousands of canvas rectangle
items per second and I have noticed that the memory usage leaks badly.

The code below illustrates the problem:

#---------------------------------------------------------------
import Tkinter as tk
import random

r = tk.Tk()

c = tk.Canvas(r)
c.pack(fill=tk.BOTH, expand=tk.YES)

# draw 400 rectangles
objs = []
for i in range(20):
    for j in range(20):
        obj = c.create_rectangle(i*10, j*10, i*10+10, j*10+10,
fill='#888888', outline='#888888')
        objs.append(obj)

def run():
    # loop indefinitely and randomly change the canvas item colours
    while True:
        obj = random.choice(objs)
        red = random.randint(0,255)
        green = random.randint(0,255)
        blue = random.randint(0,255)
        colour = '#%02x%02x%02x' %(red, green, blue)
        c.itemconfigure(obj, fill=colour, outline=colour)
        r.update()

tk.Button(r, text='Run', command=run).pack()
tk.Button(r, text='Close', command=r.destroy).pack()

r.mainloop()
#----------------------------------------------------------------------

So as you can see, each iteration of the while loop just does an
itemconfigure on a random item on the canvas and then an update to
process the redraw.

I've tried periodically deleting the canvas items and redrawing them and
even periodically destroying the Canvas object itself and restarting
from scratch.  Alas, memory is never released.  So, I come to the
conclusion that the memory leak must be in the Tcl/Tk interpreter.

Is there any way of forcing the Tcl/Tk interpreter to release memory ?

Can anyone help shed some light on this mystery ?

Regards,

John McMonagle

Hi John,

  I confirm your memory leakage on the code you sent,
on a Windows 7 machine running python 2.7 / Tk 8.5

And when one comments out the c.itemconfigure line, memory usage is
constant, so the problem is there.

And looking in Tkinter.py, the itemconfigure method on a Canvas object
calls _configure on the base class, but the problem is not on the Tkinter
side, it is in Tk.

Thank you for the links to tkTreeCtrl and TableList. 

I have not used custom Tk modules before. Where do you recommend I place
the custom Tk code in order for Tkinter to find it?

I'm using the 32-bit version of Python 2.7 for Windows.

Malcolm

Hi Wayne,

Thanks! I'm following your strategy and it works well for me.

Thank you! These are excellent references to generic events. How does
one discover (virtual) events like <<Copy>>, <<Paste>>, <<Selection>>,
<<ListSelection>>, etc.

import Tkinter as tk
root = tk.Tk()
b1 = tk.Button(root, text='hi')
b2 = tk.Button(root, text='bye')

b1.pack()
b2.pack()

b1.pack_forget()
b1.pack()

------

As for grid I'm not sure how to do it unless you have placed them in
different row/column - then you just have to use widget.grid(row=widget2row,
column=widget2col)
widget2.grid(row=widget1col, column=widget1col)

Well, that pattern.

HTH,
Wayne

Wondering if there's a menu event I can bind to that's related to
the currently selected menu item? By menu item I mean the items
that show up in a popup menu like New, Open, Save, etc.
Use case: I would like to update a statusbar area of our

item.

Message-ID: <1290205538.28531.1406225927@webmail.messagingengine.com>

I'm looking for an example of how to use <<MenuSelect>> to
determine currently selected menu item.

Use case: Display a context sensitive help message in an
application's statusbar as a user navigates through various menu
items.

Thank you,
Malcolm

Hi,

Maybe you are better off with a simple Motion event, you can access the
menu item under the mouse pointer through the menu's index() method
(from the menu manpage:

Many of the widget commands for a menu take as one argument an indicator
of which entry of the menu to operate on. These indicators are called
indexes and may be specified in any of the following forms:
(...)
@number
    In this form, number is treated as a y-coordinate in the menu's
    window; the entry closest to that y-coordinate is used. For example,
    ``@0'' indicates the top-most entry in the window.

)
So, in this simple example, you will surely see the point:

################################

from Tkinter import *

root = Tk()
m = Menu(root)
m.add_command(label='foo')
m.add_command(label='bar')
m.add_command(label='blah')

root.bind('<3>', lambda event: m.tk_popup(event.x_root, event.y_root))

def callback(event):
    try:
        print m.entrycget(m.index('@%d' % event.y), 'label')
    except TclError:
        print 'this must have been the tearoff or something'

m.bind('<Motion>', callback)

root.mainloop()

################################



I hope this helps

Hmm. Need to draw text on an angle on a canvas but no mention of angled text in the documentation.

Does anyone know if there is actually a way to do this or is it time to implement a vector font and do it the hard way?

Thanks

In Tk-8.6 the canvas text element has a new -angle option, so using
Tk-8.6 is definitely the best way to do this.
If installing Tk-8.6 is not an option for you, you may try Blt which
seems to be able to rotate text according to: http://wiki.tcl.tk/3365 or
to use tkImg to create a window-image object and then rotate this image
as demonstrated in http://wiki.tcl.tk/4022 . The tcl wiki shows a few
more examples (see http://wiki.tcl.tk/_/gsearch?S=rotate+text) but they
are all more or less a pain in the neck, if possible I recommend using
Tk-8.6, it's probably much easier to install it and recompile Python to
use it than to set up rotated text with older tk versions.

Regards

Michael

Kevin,

> Try <<MenuSelect>>.

Thanks for the recommendation. Any suggestions on how I can determine
the currently selected menu item in the event raised by <<MenuSelect>>?

# here's how I create my popup menu
popup = tk.Menu( menubar )
popup.bind( '<<MenuSelect>>', statusbarUpdate )

# here's the command I bind to
def statusbarUpdate( event=None ):
    for key in dir( event ):
        print key, getattr( event, key )

This outputs the following information as I move between menu items (eg.
the event is being raised properly).

Note: There seems to be no way to determine the current menu widget
(event.widget is a string vs. widget reference).

char ??
delta 0
height ??
keycode ??
keysym ??
keysym_num ??
num ??
send_event False
serial 238
state 0
time 1585806557
type 35
widget .#52754872.#52754872#52755392 <-- string vs. widget reference
width ??
x 36160384
x_root 487
y 53363120
y_root 307

Any suggestions appreciated!

Thank you,

Hi Michael,

Thank you for your idea to use the <Motion> event. That works when I use
the mouse, but it doesn't work when a user uses the cursor keys to move
between menu items.

I can trap the <<MenuSelect>> event - I just need a way to determine the
current menu widget and its active index.

The event object passed to the function I bind to has event.widget
reference to a string vs. a widget. Do you have any ideas on how I can
determine the active menu widget and its active index independent of a
current event object?

Thank you,
Malcolm

Hi Malcom,

Change your statusbarUpdate for the following, which will print out
the index of the currently selected menu item:

def statusbarUpdate( event=None ):
   print tk.call(event.widget, "index", "active")

Note that this uses tcl/tk code, where Tkinter code should be used,
but it seems the corresponding tkinter code is broken, e.g., with

def statusbarUpdate( event=None ):
   print popup.index('active')

...always returns None on changing the menu selection.

My test code below

from Tkinter import *
import tkFont
tk = Tk()

def statusbarUpdate( event=None ):
   print tk.call(event.widget, "index", "active")

menubar=Menu(tk)
tk.config(menu=menubar)
popup = Menu( menubar )
menubar.add_cascade(label="MyMenu", menu=popup)
popup.bind( '<<MenuSelect>>', statusbarUpdate )
popup.add_command(label="Option 1")
popup.add_command(label="Option 2")
popup.add_command(label="Option 3")
tk.mainloop()

Thank god, Tkinter offers a solution which is actually much easier
than my first example :)

Hi Michael,

At least in Python 2.5.4 linked to Tk 8.4 (Windows version),
the following fails  because event.widget holds a string (the tcl/tk
widget name), not a Tkinter class.

> def callback(event):

Maybe fixed in later editions, but if one wants a solution that will
work on older versions...

I see, this happens only with cascade menus, in my example I only had a
popup menu, for which it worked as expected. Right now I am trying to
figure out what's wrong with Tkinter (it's definitely a bug within
Tkinter.py, and I doubt that it has been fixed since 2.6.5), I'll send
another post when I know more. Of course for now you are right, your code
"just works" :)

I believe this is because the button in the menu is treated as a different
widget by Tk, so the correct call would be:

    def statusbarUpdate(event):
        print event.widget.index('active')

However, using this I get an error:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1410, in
__call__ return self.func(*args)
  File "test2.py", line 18, in statusbarUpdate
    print event.widget.index('active')
ValueError: substring not found

This is apparently because event.widget is not (as expected) a widget
instance but a string which looks like .#153369036.#153369036#153369644

Trying to feed this string to nametowidget() I get the following error:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1410, in
__call__ return self.func(*args)
  File "test2.py", line 18, in statusbarUpdate
    print tk.nametowidget(event.widget)#.index('active')
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1079, in
nametowidget w = w.children[n]
KeyError: '#153369036'

The problem is apparently that the widget name of the menu's "button" is
assigned by Tk and there does not seem to be a way to access this
subwidget from within Tkinter.
Besides this I don't understand why this does not happen with the context
menu from my previous example but only with a cascaded menu.

This looks to me like a bug in Tkinter, but I don't have an idea how this
could ever be fixed (at least without dealing with _tkinter's internals),
so we probably will have to stick with Michael's workaround.

Regards

Michael

Michael,

Thank you! That's EXACTLY the solution I was looking for :)

Change your statusbarUpdate for the following, which will print out
the index of the currently selected menu item:

def statusbarUpdate( event=None ):
   print tk.call(event.widget, "index", "active")

Note that this uses tcl/tk code, where Tkinter code should be used,
but it seems the corresponding tkinter code is broken, e.g., with

def statusbarUpdate( event=None ):
   print popup.index('active')

...always returns None on changing the menu selection.

My test code below

from Tkinter import *
import tkFont
tk = Tk()

def statusbarUpdate( event=None ):
   print tk.call(event.widget, "index", "active")

menubar=Menu(tk)
tk.config(menu=menubar)
popup = Menu( menubar )
menubar.add_cascade(label="MyMenu", menu=popup)
popup.bind( '<<MenuSelect>>', statusbarUpdate )
popup.add_command(label="Option 1")
popup.add_command(label="Option 2")
popup.add_command(label="Option 3")
tk.mainloop()

This fails in 32-bit Python 2.7 for Windows (linked to Tk 8.5 with

I can confirm that this bug still exists in 32-bit Python 2.7 for
Windows for both standalone and cascading menus.

Your example fails for both context and cascading menus under 32-bit

I believe this is because the button in the menu is treated as a
different
widget by Tk, so the correct call would be:

    def statusbarUpdate(event):
        print event.widget.index('active')

However, using this I get an error:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1410, in
__call__ return self.func(*args)
  File "test2.py", line 18, in statusbarUpdate
    print event.widget.index('active')
ValueError: substring not found

This is apparently because event.widget is not (as expected) a widget
instance but a string which looks like .#153369036.#153369036#153369644

Trying to feed this string to nametowidget() I get the following error:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1410, in
__call__ return self.func(*args)

    print tk.nametowidget(event.widget)#.index('active')
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1079, in
nametowidget w = w.children[n]
KeyError: '#153369036'

The problem is apparently that the widget name of the menu's "button" is
assigned by Tk and there does not seem to be a way to access this
subwidget from within Tkinter.
Besides this I don't understand why this does not happen with the
context

This looks to me like a bug in Tkinter, but I don't have an idea how

 label, customize location/appearance of tear-off window)
Message-ID: <1290388686.21953.1406467541@webmail.messagingengine.com>

I've been experimenting with Tkinter tear-off menus and have the
following questions (relative to Windows):

1. Is there a way to change the default appearance of the
"------" menu label that is used to indicate a tear-off menu -OR-
is there a way to programmatically convert a menu widget to a
torn-off state? Note: The tear-off menu item does not have a
'label' property.

2. Is there a way to customize the location and appearance of the
window that contains a tear-off menu? On Windows, the tear-off
menus appear at random(?) places on the desktop. And these
windows have min/max buttons and are resizable - all behaviors
that IMO don't make sense for a floating tear-off menu. What I
would like to do is capture a reference to the window of a
tear-off and customize it like I would any other Toplevel()
window. Is this possible?

Note: I can detect the tearoff event by using the tearoffcommand=
option when I create a menu. I think this event is where I want
to take control of the tear-off menu's window properties? But how
to get a reference to the tear-off menu's window (and does it
exist yet?).

Thank you,
Malcolm

Not sure, maybe you could find out the tearoff's x and y coords and use
event_generate() to trigger the mouse event or so...

Here on linux (I guess it should be the same on windows) the
tearoffcommand takes two arguments, first the menu itself and second the
newly created toplevel window, both as strings however, and Tkinter
doesn't know about the toplevel, so you will have to use the tcl-syntax
again :(
See this example:

#########################
from Tkinter import *
root = Tk()

def foo(menu, top):
    root.nametowidget(menu).add_command(label='baz')
    root.tk.call('wm', 'resizable', top,  '0', '0')

m = Menu(root, tearoffcommand=foo)
m.add_command(label='foo')
m.add_command(label='bar')
m.add_command(label='blah')

root.bind('<3>', lambda event: m.tk_popup(event.x_root, event.y_root))

root.mainloop()

You can manually create a tearoff from a menu:
    % .m clone .mt tearoff
and post it at a desired location:
    % .mt post 100 100
As suggested in the other message, you can use "wm resizeable" to make
it not change size:
    % wm resiz .mt 0 0
(Of course, I only tested this on linux, so on Windows YMMV)

Unfortunately, the menu 'clone' subcommand does not seem to be wrapped
in Python.   You can add it, but it'll be gross and touches stuff that
should be considered implementation details of Tkinter (works with
all python2.x I'm aware of, though):

# ----------------------------------------------------------------------
import Tkinter, types
def makewidget(master, klass, path):
    path = str(path)
    self = types.InstanceType(klass)
    self._name = path[len(master._w)+1:]
    self._w = path
    self.children = {}
    master.children[self._name] = self
    self.master = master
    self.tk = master.tk
    return self

def tearoff(menu):
    child = str(menu) + ".tearoff"
    menu.tk.call((menu, "clone", child, "tearoff"))
    return makewidget(menu, Tkinter.Menu, child)
# ----------------------------------------------------------------------

And then you'll find that 'wm_resizable' is not available because Menu
is not a subclass of Wm.  Just call it directly through Tk:
    >>> mt = tearoff(m)
    >>> mt.tk.call("wm", "resizable", mt, 0, 0)
    >>> mt.post(100, 100)

This is interesting, I never heard about that. And, from man menu I see
that menubars are also cloned, which might explain the troubles with the
menubars and cascading menus the OP had in the previous thread, I can
confirm the same problem with <<MenuSelect>> with the torn off popup menu,
while it works all right with the "normal" one.

Subject: [Tkinter-discuss] Change the font style (bold, italic, stikethru,
 normal) of widgets without explictly knowing font?
Message-ID: <1290460904.24589.1406637959@webmail.messagingengine.com>

Is there a simple way to change the font style of widgets without
explictly knowing the widget's font?

For example: if I want to toggle the bold state of a widget's
text, do I need to determine its font, then build an equivalent
font object/expression with the font style I need, and pass that
full font description to widget.config() or can I use a shortcut
technique that allows me to pass 'bold' or 'normal' to control a
widget's font.

Thank you,
Malcolm

Label(root, text='Font fun', font=('Arial', 100, 'bold')).config()['font']
returns a tuple - and since you can't modify a tuple, you'll have to
determine the current font. There may be a shorter way, but here's what you
can do:

mylabel.config(font=mylabel.config()['font'][4][:2] + ('normal',))
mylabel.config(font=mylabel.config()['font'][4][:2] + ('bold', 'italics'))

And that should work.

If you don't explicitely define the label's font, the font is a string
(at least here, on linux):

>>> from Tkinter import *
>>> l=Label(text='foo')
>>> l.pack()
>>> l.cget('font')
'Helvetica -12 bold'

so you can do:

def swapfont():
    if 'bold' in l.cget('font'):
            l.config(font=l.cget('font').replace('bold', 'normal'))
    elif 'normal' in l.cget('font'):
            l.config(font=l.cget('font').replace('normal', 'bold'))
    else:
            l.config(font=l.cget('font')+' bold')
 
which is not too nice, either.
If you want to do fancy things with fonts, I'd try tkFont, with a
tkFont.Font() you can easily configure all kinds of font attributes.

Regards

Michael

I get strings as well (32-bit Python 2.7 under Windows 7).

I agree with you - tkFont is definitely the way to go.

Subject: [Tkinter-discuss] how make active python 3 use active tcl on mac os?
Message-ID: <AANLkTinfC8UBv3XJ3q+UxT7OYHVQRUNhOJYavE6K-b_u@mail.gmail.com>

I apologize that this question is somewhat unique to the ActiveState free
products, not the generic Python. I asked the question at the ActiveState
support forum but it appears to be dead.

I installed ActiveState Python 3.1.4, and also ActiveState Tcl/Tk, both on
Mac OS X 10.6.

Python3 executing "import * from tkinter" is getting and executing the Apple
version of Tcl/Tk which is level 8.5.7. It appears to be getting it from
/System/Library/Frameworks/Tk.framework and Tcl.framework.

The ActiveTc (level 8.5.9) is in /Library/Frameworks rather than
/System/Library Frameworks. It contains a bug fix that I need.

Any suggestions on how I tell python3 to find the later Tcl/Tk instead of
the Apple one?

Also just by the way, how in program code can you check the release level of
Tk or ttk?

Thanks,

Dave Cortesi

I have no direct experience with how the ActiveState folks package up 
their Python installers but my guess is that the Python 3.1 is launching 
in 64-bit mode and, at the moment, the only "standard" 64-bit non-X11 Tk 
is the one Apple supplies in 10.6 /System/Library.  The A/S version 
probably attempts to use it in 64-bit mode.  If you don't really need to 
run in 64-bit, try running it in 32-bit mode which may very well link 
with the A/S Tk 8.5.  I expect that either of these should work:

arch -i386 /usr/local/bin/python3.1

or 

arch -i386 /Library/Frameworks/Python.framework/Versions/3.1/bin/python3

You can tell which Tk is being linked to for the 32- and 64-bit version 
with:

otool -L $(arch -i386 python3 -c 'import _tkinter;\
               print(_tkinter.__file__)')
otool -L $(arch -x86_64 python3 -c 'import _tkinter;\
               print(_tkinter.__file__)')

Subject: [Tkinter-discuss] simple scrollbar... not so simple
Message-ID: <10315.1229.qm@web56001.mail.re3.yahoo.com>

Hi all,

I have a list of checkboxes and label/entry pairs which I'd like to have in a scrollable widget.

So I built something like this (in this example I put just labels):

from Tkinter import *

r=Tk()
tx=Text(r) # hosts the frames and allows scrollbar
sb=Scrollbar(r,command=tx.yview)
tx['yscrollcommand']=sb.set
f=Frame(tx) # hosts my stuff
f.grid()
tx.grid()
sb.grid(row=0,column=1,sticky=NS)
for i in range(50):
  Label(f,text=('line #%d' % i)).grid()
	
r.mainloop()

The scrollbar appears, but is inactive (grayed out), and has no slider.

What am I missing?

Thanks,
SxN

Hi Sorin,

  I gave up trying to get scrolling frames to work.

Much simpler to do it with a Text widget. E.g,
for a Text item WGT and a Button item btn:

    btn=Button(WGT, text="Do it", cmd=self.someCmd)
    WGT.window_create(END, window=btn)

With this method, pack is not needed. The parent of the widgets
that you place in the Text widget needs to be the Text widget.

well, this was interesting, I didn't know about arch. As you supposed,
running python3 produces a Python process that Activity Monitor says is
"Intel (64 bit)".

However, arch -i386 python3 produces exactly the same thing as I get using
arch -x86_64, namely, an Intel(64 bit) process (and loading the same
_tkinter.so). Hmmm. This would suggest there is only the one architecture
defined in its binary?

applying otool -L to the _tkinter.so that python3 is loading reports
"/System/Library/Frameworks/Tcl.framework/Versions/8.5/Tcl" and etc, so
indeed, the Apple Tcl is baked into the dynamic load lib distributed with
Python3.

I cannot find any other version of _tkinter.so that might have been
installed by ActiveTcl. So I'm pretty baffled, as well as disappointed that
there's been no response in the ActiveState "support" forum.

However, thanks for your help!

Ah, sorry, I forgot this was 3.1: unless the ActiveState people 
backported some stuff from the upcoming Python 3.2, the "arch" trick 
won't work on OS X 10.6 to select between 32-bit and 64-bit modes.  
Check the framework bin directory 
(/Library/Frameworks/Python.framework/Versions/3.1/bin) for something 
like a python3-32 executable and, if found, try using that.

Hi Sorin.

Full example with at least vertical scrolling

from Tkinter import *

class ScrolledText(Frame):

    def __init__(self, master, **keywords):

        # Set some defaults
        if not keywords.has_key("width"): keywords["width"]=24
        #if not keywords.has_key("height"): keywords["height"]=20
        if not keywords.has_key("bg"): keywords["bg"]="white"
        if not keywords.has_key("relief"): keywords["relief"]="sunken"

        Frame.__init__(self, master)
        self.config(bg=keywords["bg"])

        # Scrollbars
        scrollbar = Scrollbar(self, orient=VERTICAL)

        # Create the Text wgt
        self.text=Text(self, yscrollcommand=scrollbar.set, **keywords)
        scrollbar.config(command=self.text.yview)

        scrollbar.pack(side=RIGHT, fill=Y)
        self.text.pack(side=LEFT, fill=BOTH, expand=True)
        self.scroll=scrollbar

tk = Tk()

st=ScrolledText(tk)
st.pack(expand=True, fill=BOTH)
st.text.insert(END, "Buttons:\n")
b1=Button(st.text, text="Hello 1")
st.text.window_create(END, window=b1)
st.text.insert(END, "\n")
b2=Button(st.text, text="Hello 2")
st.text.window_create(END, window=b2)

tk.mainloop()

Hi David,

  Sorry for a vague answer, but I had similar problems
some years ago and the solution was to recompile
python, and in a particular file put the search path
for the tk library.

Can't remember offhand which file,

Mick

I don't know about the mac, here on debian linux I have to do

    export LD_LIBRARY_PATH=/usr/local/lib

before compiling Python, otherwise it fails to find Tcl/Tk.

That's not exactly true, for example look at the Pmw.ScrolledFrame which
works very well. I have also seen other solutions here and there, but
imho the Pmw.ScrolledFrame is the  best (at least once you found out how
to set up the widget's options :) , so I wouldn't bother setting up my
own scrolled frame widget.

Mick, you saved me!

My test code looks now like this (I hope HTML tags are honoured):

from Tkinter import *

r=Tk()
tx=Text(r,width=6) # hosts the frames and allows scrollbar
sb=Scrollbar(r,command=tx.yview)
tx['yscrollcommand']=sb.set
f=Frame(tx) # hosts my stuff
<b>tx.window_create(END,window=f)</b>
tx.grid()
sb.grid(row=0,column=1,sticky=NS)
for i in range(50):
  Label(f,text=('line #%d' % i)).grid()
	
r.mainloop()

Instead of "grid" for the frame, I used a "window_create", as per your example, and ta-da! it works.

The Text width is an arbitrary 6, I don't know how to make it as large as the frame, but not larger, and I also don't know how to show the scroll bar only when needed. But I can live with these two minor shortcomings, and the real application behaves fine.

Thank you
SxN

Are you sure `python3-32` (and `python3-64`) are included in Python 
3.1.2, or is this something new in 3.1.3 (svn)?

I certainly don't see the -32/-64 binaries in ActivePython 3.1.2.4 
(based on Python 3.1.2). So if 3.1.2 is supposed to generate these - 
then this is an ActivePython bug that needs to be fixed.

I didn't find them; I should have replied to Ned's comment. The
ActivePython 3.1.2.4 interpreter is I believe intel-only (not a 'fat'
binary with PPC code too) and 64-bit only. Don't know if this is a bug
or not (probably not). What appears to be a bug or at least an
oversight, is that it can't call ActiveTcl; it's linked to the Apple
Tcl.

3.1.2 and 3.1.3 should be identical in that respect.  The most recent 
3.1.2 installers with 32-bit/64-bit support that I built (around 
3.1.2rc1 time) had them:

As I noted earlier, 32-bit/64-bit 3.1 (and 2.6, for that matter) builds 
do not support architecture selection via the arch command on 10.6, 
which will always prefer to launch 64-bit if possible.  A feature was 
added to 2.7 and 3.2 to support this.  For 2.6 and 3.1 systems, the 
standard ./configure options --with-universal-archs="3-way", "intel" or 
"all" create the separate 32- and -64-bit executables.  Running on 10.6 
you can see the problem with the ActivePython 3.1.2.4 - it always runs 
in 64-bit mode:

$ python3.1
ActivePython 3.1.2.4 (ActiveState Software Inc.) based on
Python 3.1.2 (r312:79147, Oct 22 2010, 10:36:09) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
Module readline not available.
>>> import sys
>>> sys.maxsize
9223372036854775807
>>> ^D
$ arch -i386 python3.1 -c 'import sys;print(sys.maxsize)'
9223372036854775807
$ arch -x86_64 python3.1 -c 'import sys;print(sys.maxsize)'
9223372036854775807

(Also, I don't have a 10.5 Intel system handy at the moment but I wonder 
how the ActivePython Tkinter would work at all there since there is no 
/System/Library/Frameworks/Tk.framework/Versions/8.5/Tcl or Tk).

Well, I was afraid I'd have to make an embarrassed apology for overlooking
them, but no, or at least not just yet. This is an install from last week:

[Sat 11/27] cd /Library/Frameworks/Python.framework/Versions/Current/bin
[Sat 11/27] ls -l python*
-rwxr-xr-x  2 root  admin  24968 Oct 22 10:40 python3*

-rwxr-xr-x  1 root  admin  24968 Oct 22 10:40 pythonw3.1*

I'd love to see the -32/-64 versions turning up but I did a find at the
/Library level for '*-32*' and didn't see them.

Just to be clear: I was talking about test installers for the python.org 
OS X distribution.  Srid is the person to talk to about the ActiveState 
Python distributions so I'm going to bow out of this discussion now.

I suggest you try python.org python instead of ActiveState Python. At 
least for 2.6 and 2.7 it will preferentially use ActiveState's Tcl/Tk if 
found. However, I have not confirmed that with python.org Python 3.1 and 
I don't know what major version of Tcl/Tk it wants (8.4, 8.5 or 8.6).

Ok, thanks for this background information. Strangely enough, when I now build ActivePython 3.1.3.5 (to be released by end of this week), I see the -32/-64/-all binaries. It was only missing from the 3.1.2.4 build (was it because of having 3.1.2.3 - ppc+i386 - in /Lib/Frmwrk?). Using the same build:

$ python3.1-64 -c 'import sys;print(sys.maxsize)'
9223372036854775807
$ python3.1-32 -c 'import sys;print(sys.maxsize)'
2147483647

Further I will also update the FAQ <http://goo.gl/zGD3T>, which is incorrectly suggesting `arch` for 2.6 and 3.1 too.

Re the last, _tkinter.c in the Python 3.1.3 dist says, "Only Tcl/Tk 8.3.1
and later are supported." The version distributed with Mac OS 10.6 is 8.5.7
and ActiveState is currently 8.5.9.

Re the main suggestion, apparently the only way to get Python3 for OS X from
Python.org is to download the source and build it. I have (you can see)
downloaded the package but frankly I find the build instructions in
configure* and in the global README and Mac/README to be head-spinning.
Yeah, sure, it's just configure; make; sudo make install; -- except if I
want it in /Library/Frameworks, it's configure --enable-framework, plus if I
want the 32- and 64-bit versions, it's configure --enable-framework
--enable-universalsdk --with-universal-archs=intel ... I think.

Supposing I did this, will this fix the original problem that I started out
to solve, namely, getting Python3 to link to ActiveTCL? It seems not,
because Mac/README says "If you want Tkinter support you need to get the OSX
AquaTk distribution, this is installed by default on Mac OS X 10.4 or
later." In other words, it's going to build _tkinter.so to use
*/System*/Library/Frameworks/Tcl
(Apple's) and not /Library/Frameworks/Tcl (Active's). Where is that
configured? I've no idea.

It does appear that the Mac installer is not yet available. There is  
such an installer for Python 3.1.2:
<http://www.python.org/download/releases/3.1.2/>
if you can live with the previous version.

That sounds plausible, but I confess I've not tried it. Do you really  
need both 32 and 64 bit versions?
--enable-framework is essential if you want Aqua Tcl/Tk (it might be  
the default on Mac OS X, but I prefer not to risk it).

I think you are misinterpreting the README. In the past whenever I  
have built Python from source it has used my own Tcl/Tk (which is from  
ActiveState). I would be very surprised if that has changed.

Don't bother building it yourself.  Either use the 3.1.2 installer from 
here:

http://www.python.org/download/releases/3.1.2/

or wait a bit until the 3.1.3 OS X installer becomes available (I don't 
know how long that will be).  Either way, the 32-bit Pythons installed 
by the python.org installers will use an ActiveState Tcl/Tk 8.4 (from 
/Library/Frameworks) if available at run time, otherwise they will use 
the Apple-installed Tcl/Tk 8.4 in /System/Library/Frameworks.

Does Tkinter (directly of via tk/tcl) support different styles of
underlining, eg. dotted underlines or squiggly underlines
(typically used to indicate a word is misspelled in MS Word or
FireFox)?

Thank you,

Message-ID: <1291103509.26051.1407830119@webmail.messagingengine.com>

Tkinter has a cool way to create named font objects that can be
used across widgets. When a named font object is updated, all the
widgets that use the named font automatically update their fonts
as well.

Is there a similar way to implement "named colors", eg. where we
can update a "color object" in one place and have all widgets
that reference this color object update their colors as well?

Thank you,

Hi,

Thus spoketh python at bdurham.com

This is #30 on the Tk-9.0 wishlist, see:

    http://wiki.tcl.tk/4055

and to implement this in Python is surely not trivial, so I doubt that
such a thing exists (though I agree to you that it would be desirable).

Regards

Michael

I don't think so, I guess tk internally simply uses an underlined font.

However, if you want to use a text widget, you may want to look at the
text man page, section TAGS, option bgstipple:

-bgstipple bitmap
  Bitmap specifies a bitmap that is used as a stipple pattern for the
  background. It may have any of the forms accepted by Tk_GetBitmap. If
  bitmap has not been specified, or if it is specified as an empty string,
  then a solid fill will be used for the background.


Maybe it is possible to set up a "misspelled" tag using an
appropriate bitmap, though it might take some tweaking to adapt one
bitmap to be usable with any given font.

Michael
