Subject: [Tkinter-discuss] How to export the image drawn by canvas?
Message-ID: <BAY128-W1010AD17DA2C272C10F8BEB1D30@phx.gbl>


Dears,:

I use canvas to make animation by continuously displaying objects.
Now I want to export what is displayed in canvas to an image file(.bmp, jpeg,png,... is OK)
Is there such function in tkinter and how can I attain this?

Thank you very much!

You can use the canvases postscript() method to export the whole canvas
or a part of it to a postscript file or alternatively let postscript()
return the postscript data. If necessary, you can use PIL to convert
the postscript into png or jpeg or so.

I hope this helps

  I don't believe there's a function.

  I've read about people making functions that save a postscript [1], and
open a command shell to instruct ImageMagick to conver it, and I've read
about people using software that bridges tkinter with PIL [2].

  As for storing animations, I've never heard of people doing that with
tkinter.

Hi Nessus,

  I had the same problem a while back and fixed it after some
messing around. Stupidly I did't write down my fix.

I seem to remember that I had to update some software
which was NOT python. Maybe XCode. Make sure
you have the most recent versions of XCODE.

Sorry I cannot help more definitively.

Subject: [Tkinter-discuss] Execute Python callback from Tk widgets
Message-ID: <4ACCA070.3050603@codebykevin.com>

Hi all,

I'm running into some difficulty in wrapping a Tk widget from Python in 
a way that will allow me to execute Python callbacks/commands.

I'm trying to incorporate widgets from TclMacBag 
(http://tclmacbag.autons.net/) into one of my Tkinter programs. 
Specifically, I'm trying to use the "stylebutton" widget.  At their 
base, the TclMacBag stylebuttons are just ttk::buttons with a custom 
style. However, they are constructed as megawidgets, their internal API 
is quite complex, and so getting at their underlying button and style 
implementation from Tkinter is difficult.

My current approach is to define a simple Tcl/Tk package that exposes 
the functionality I need, and then use self.tk.call() to access this 
from Tkinter. Here's an abbreviated example:

##Tcl code in "macstylebutton" package
proc macstylebutton {w child img cmd layout msg row column } {


     ::tclmacbag::stylebutton $w.$child -image $img -style $layout 
-command $cmd
     grid $w.$child -row $row -column $column
     balloon $w.$child $msg
}


#Python function
    def styleButton(self, parent, child, img, cmd, style, msg, row, column):
         self.tk.call('package', 'require', 'macstylebutton')
         self.tk.call('macstylebutton', parent, child, img, cmd, style, 
msg, row, column)


#Python GUI code that calls the function
        self.deletebutton=self.styleButton(self.topframe, 'delete', 
self.logout, lambda: self.authorizeCommand(self.deletePackage), 'mail', 
'Delete package', 0, 2)

This code lays the buttons out correctly, but the Python callback is not 
executed. It seems to be correctly set up; running "print cmd"  yields 
output like this:

<bound method phynchronicityApp.infoPackage of 
<__main__.phynchronicityApp instance at 0x3f1af8>>

but the actual callback doesn't fire.

My theory as to the problem is this: it appears that the widget is 
responding to the "cmd" parameter as a Tcl command, and since it's 
actually a Python command, nothing's happening. I know Python/Tkinter 
can execute Tcl commands through 'call' or 'eval,' but it doesn't appear 
that Python commands can be passed to raw Tk widgets. Indeed, I had 
tried to simply configure the buttons via something like 
'self.deleteButton.configure(command=foo'), but Tkinter returned an 
error--something about a NoneType object lacking a 'configure' method.

My question is this: how can I get Python callbacks to fire when a raw 
Tk widget is being called via 'self.tk.call'? Do I have to write a fancy 
wrapper that turns the widget into a Python object that will respond to 
Python callbacks, or is there a simpler way to do this?

Thanks,
Kevin

I use this class (from the RO package's module RO.TkUtil):

Thanks for this reference. It led me directly to the "register" method 
in Tkinter. Now my commands are as simple as 
self.register(self.infoTable), and they work.

Best,

Subject: [Tkinter-discuss] Need help on gui focus l
Message-ID: <4AD5421B.3070000@gmail.com>

Hi folks,

I am using Tkinter to do a simple GUI for my program.

It contains A MainGui and A ChildGui:
A button on the MainGUI will popout the childgui.
On the childgui there is a browse button which popout a dialog to allow
user to browser and choose a file.

I have no problem at doing them.

The problem is after the uesr choose a file the focus will return to the
MainGui intead of the childgui. The child gui just go hide behind the Main.

I've tried focus_set, focus_force but none of them seem work.

I did some research but found nothing working. It's not a big problem,
but is really really annoying.
(Actually I notice the examples from some python book I am reading has
the exact same problem. The author even tried to spawn the child gui
away from the main one, so when the focus return from the browse dialog
, the maingui won't block the child one~~ Is that how tkinter should work?)

Any suggestions?

Thanks in advance~~


Frank

I cannot reproduce this behavior here (linux), maybe it is a platform
specific problem ? I tried the follwing which works for me as expected:

### CODE ###
from Tkinter import *
import tkFileDialog

root = Tk()

top = Toplevel()
top.withdraw()
top.protocol('WM_DELETE_WINDOW', top.withdraw)

def filedialog():
    print tkFileDialog.askopenfilename()

b0 = Button(top, text='filedialog', command=filedialog)
b0.pack(padx=100, pady=100)

def popup():
    top.deiconify()
    b0.focus_set()

b1 = Button(root, text='popup', command=popup)
b1.pack(padx=100, pady=100)
root.mainloop()
### CODE ###

In case I just did not understand exactly your problem,
could you post a short code snippet here that shows
the problem and tell us which platform you are using, please ?

The code given exhibits the problem on my Ubuntu Linux box. For the sake of clarity I enumerate three windows involved in this code:

- The MAIN window which has a button marked "popup" in it.
- The CHILD windows which has a button marked "filedialog" in it.
- The OPEN window which is the tkFileDialog

On my machine clicking on the "popup" and "filedialog" buttons works ok, but once you select a file and click OPEN, then what is on top and visible is the MAIN window whereas what the original poster wanted was to see the CHILD window. Even worse, if (starting from scratch again) you click the "popup" button, then drag the resulting CHILD window to a slightly new position then click the "filedialog" button, the OPEN window appears *under* the CHILD window which seems less than useful.

You are right, this actually sounds less than useful and it is surely
not the way it is supposed to be. I cannot reproduce this here (debian
lenny, Python-2.5.2, Tk-8.4.19) though. I guess this is most likely a
bug in your version of Tk.
I wrote a tiny tcl script that does basically the same as the python
code from my last post, you can try if it exhibits the same bug, then
we could at least be sure that it's not python that causes the bug.

###CODE###
 #!/usr/bin/env wish

toplevel .t
wm withdraw .t
wm protocol .t WM_DELETE_WINDOW {wm withdraw .t}
button .t.b0 -text "filedialog" -command tk_getOpenFile
pack .t.b0 -padx 100 -pady 100
button .b1 -text "popup" -command {wm deiconify .t}
pack .b1 -padx 100 -pady 100
###CODE###

The behavior of your tcl script is identical to the Python code so it's not Python causing the problem. I'm running Ubuntu 8.04 (Hardy), Python 2.5.2 and I don't know enough about tcl to find out its version. The file /usr/share/doc/tk8.4/README says it is 8.4.16.

I asked synaptic for the version :)
So if it is Tk which is broken, in case that upgrading Tk is not an
option, maybe you can try a workaround using the Toplevel's lift()
method .

Subject: [Tkinter-discuss]  Newbie question - displaying data
Message-ID: <25960335.post@talk.nabble.com>


Hi,

I am new to TKinter and struggling somewhat.

I have a Python program that reads a number of temperatures from sensors in
tanks and pipework, that is working fine.  I now want to display those
temperatures, ideally a simple diagram of the pipework with boxes displaying
the values.  I don't need any user input, it just runs forever once started

My initial thought was to use a text widget for the whole page and update
the areas that show the values.

Is that the best way to do it?  Can anyone give me some pointers on
constructing the program?

Thanks

Mick

  This sounds like a great use for **the canvas widget.**
  1.  Draw layout with canvas lines and rectangles.
  2.  Draw text representing sensor readings onto canvas.
  3.  Refresh display by reconfiguring text, once a second.

  The great thing about canvas is that -- once you've got
  text placed on it, you can just alter the text via the
  canvas.itemconfigure method.

  Here's a rendering of your program:
------------------------------------------------------------------------
from tkinter import *

class BasicCanvasFrame1(Canvas):
    """Basic canvas frame.
    (Strictly, NOT a Frame -- but we're using it sort of like one.)
    For convenience, there is a size parameter offering typical sizes:
      320x200   "CGA"
      640x480   "VGA"
      1024x768  "XGA"
      1280x1024 "SVGA"
                "FULL"  -- full screen mode
    For organizing's sake, the BasicCanvasFrame suggests a function,
    "draw," for drawing onto it with.
    Also, there are some common event registrations, so that you do not
    need to register them yourself:
    * mouse clicks,
    * mouse motion,
    * key presses

  (This is longer than is strictly necessary; I'm reusing
   BasicCanvasFrame1 from my notes to make this quickly.)
  The main points of interest are:
  * MickSulleysTemperatureSensor.draw:
    (the drawing code)
  * MickSulleysTemperatureSensor.per_second:
    (the itemconfigure line)
  * BasicCanvasFrame1.__init__:
    (Canvas initialization, packing code, Canvas.after
    initialization)
  * BasicCanvasFrame1._per_second:
    (Canvas.after continuity)

  Feel free to adapt and reuse the code here.
  (If you experiment with Canvas, I might suggest using
   BasicCanvasFrame1 yourself -- it has made my own
   experimentation a lot easier.)

  Sincerely,
    Lion Kimbro

Subject: [Tkinter-discuss]  Grid Geometry Manager & ImageTk.PhotoImage
Message-ID: <26012393.post@talk.nabble.com>


I cannot for the life of me figure this out.  I am trying to create a program
that will display images and have some functions to go along with it.  I am
using the grid manager to organize everything, and the basic framework is as
such:

* 2x2 grid
* Row 0, Column 0 is first image
* Row 0, Column 1 is second image
* Row 1, Column 0 is first toolbar
* Row 1, Column 1 is second toolbar

I am having trouble with the images, however, as they are being cut off
(only part of the image is being shown).  I am using Canvas objects to hold
the images.

I was able to throw in a few lines to fix most of the problems, but since it
isn't perfect, I'd like to get to the bottom of it.  The only noticeable
problem left is that if you load a vertical picture, there is space left to
the right of the image that is counted as part of the canvas.  I uploaded
the Python code and an image which demonstrates the problem.

I don't see anything that's wrong with the images here, except that
there's a 1- or 2- pixel gray border around the images. If this is what
you mean, you can probably get rid of it by specifying
bd=0, highlightthickness=0 in the Canvas constructors.

Hi Michael, Francis,

Michael, if you change the bg of the canvases, you
will see that Francis is right, the canvas extends
past the edge of the photo image.
I changed his code as follows adding the bg atributes:

panel1 = tk.Canvas(root, bg="red")
panel1.grid(row=0, column=0, sticky=tk.NSEW)
panel2 = tk.Canvas(root, bg="blue")

Francis, this behaviour is all as expected. A canvas does not
adjust its size to its contents (the jpg). It opens with a default size.
What you probably want to do is resize the canvas once the jpg is drawn.
For instance, add these lines (or some subset) at the end of openImage:

	panel1['height']=h
	panel1['width']=w
	panel2['height']=h
	panel2['width']=w

Message-ID: <20091022200317.b7f1b598.kd8atu@gmail.com>

Hello to all!

I'm working on a project that uses the Tix widgets pretty heavily (the tixGrid widgit is pretty much the centerpiece of the whole thing). It's going great on Linux, but now I need to get it running on Windows.

The instructions for building Tix and its Python extension on Win32 are confusing and appear to be outdated, so can anyone who's done it recently tell me where to start? My Win32 dev machine is running WinXP-SP3 with Python 2.6.3 and Cygwin 1.7. MSVC is not installed at present but I have access to Visual Studio 2008 if I need it.

Thanks,
-Joe

That is exactly what I did, but I cannot confirm this behavior here (on
debian linux, python-2.5.2, Tk-8.4.19), so maybe the exact behavior is
different on different platforms / Tk-versions ?

Sorry, yes, I should have specified I am working under Windows,
and was using python 2.5.4 with its default Tk.

Which asked the question why you, a major Python/Tkinter user,
have not upgraded to 2.6 let alone 3.1?

(myself, I had problems with making standalone applications
using py2exe under windows for Vista/Windows 7, so reverted
to the one that worked, but that is not for a Tkinter list).

Now I got curious and installed both python-2.5.4 and python-2.6.3 on my
old win2k box, and now I see what you mean. It has obviously nothing to
do with tcl- or python-versions and I tried several window managers
here under X and they all behave the same, so it seems to be a
difference between windows and X.
To solve this, it is surely the best to explicitely resize the canvas
when loading an image.

Sorry for the slow reply, busy week last week.

Replace Michael's filedialog function with the following:

def filedialog():
   oldFoc = top.focus_get()
   print tkFileDialog.askopenfilename()
   if oldFoc: oldFoc.focus_set()

...then you should have the behaviour you expect.
(the 'if' is necessary in case their is no prior focus).
At least on my Windows XP running Python 2.5.3

Subject: [Tkinter-discuss] getvalue fails on pmw.radioselect after using
 configure on component
Message-ID: <26136605.post@talk.nabble.com>


I am using a generic function to build Pmw.RadioSelect widgets:

    def make_checkbuttons(self, parent, buttonlist):
        """Make a multiple-selection Pmw.RadioSelect checkbuttons"""
        widget = Pmw.RadioSelect(parent,
                                selectmode = 'multiple',
                                buttontype = 'checkbutton',
                                orient = 'vertical')
        widget.pack(side = 'left', expand = True, fill = 'both', padx = 4)
        for button in buttonlist:
            widget.add(button)
        return widget

In one instance I want to configure the options on three checkboxes after
the generic creation of the widget:

        #after the generic construction of this radio button group, 
        #we need to set some specific parameters
        self.var1 = IntVar()
        self.var4 = IntVar()
        self.generalops.button('all maps same data frame').configure(state =
'disabled', padx = 15)
        self.generalops.button('leave ArcMap open').configure(command =
self.leave_open, variable = self.var1)
        self.generalops.button('export plots').configure(command =
self.export_plots, variable = self.var4)

       #doesn't matter if I pack before or after the post-configuration
        self.generalops.pack(side = 'left', anchor = 'w')

But, if I do that, self.generalops.getvalue() returns nothing for those
buttons which have been post-configured. Any suggestions?

No, wait, it has something to do with assigning a command (or a variable) to
the button. Those two buttons never show up in the list. 

Apologies for not checking that first.
