Seems like it is even easier, tktable (http://tktable.sf.net) has a python wrapper included in the demos directory.
I am not sure however if the OP had some sort of table widget in mind or if every column
should be populated with a variety of widgets.

yes, make two frames: one for the 'header' rows, and one for the scrolled
table.

I mostly have colors in the columns. So now (but I'm novice at tk and
tkinter) I use a Label with no text, padx=20,bg='red'. (or other colors).

tktable seemed daunting to install (I don't really want to find a
functional compiler on windows), so I'm looking at the other options for now.

Thanks for the tips so far!

so it's a plain display table ?  maybe something like this

    http://effbot.org/zone/wck.htm

could help; e.g. the listview widget in

    http://effbot.org/zone/wck-4.htm

could be tweaked to do exactly what you want (make sure you skim the earlier
articles too, before you start hacking).

Subject: [Tkinter-discuss] update_idletasks problem
Message-ID: <e61on2$cs$1@sea.gmane.org>

I have an application with a button that calls a method that retrieves a
page from an external wiki, so it can take a while.  I want to use an
hourglass/watch cursor to indicate to the user that the page is loading.
All the documentation suggests that the way to do this is as follows:

def my_slow_method(self):
    self['cursor'] = 'watch'
    self.update_idletasks()
    retrieve_page_from_wiki()     # placeholder for my slow retrieve
function
    self['cursor'] = ''

where "self" is my Tkinter application, defined as a subclass of
Tkinter.Frame.

The only problem is, this doesn't work.  The cursor never changes to the
hourglass!  If I comment out the last line, it does change to an hourglass
*after* retrieving the page from the wiki, but obviously that's not what I
want to do.  What's wrong?

I'm running Python 2.4 on Windows XP.

Hi all,

I use a button  to generate a toplevel window. I hope only one such window 
is existing before I close it manually. But now each time when I click the 
button a new window is created. How can I do?

How do I bind a function to the close of the window by clicking the cross in 
the up-right side?

Following is a example program. You solution or suggetstiong is very 
appreciated .

from Tkinter import *
root = Tk()
class App:
  def __init__(self, master):
        c = Button(master, text="Only one")
	c.bind("<Button-1>", lambda e, s=self:s.cb(master))
        c.pack()
  def cb(self,master):#, event):
        win = Toplevel(master)
	win.title("one")
	frame= Frame(win)
        b=Button(frame, text='ok', command=win.quit)
	b.pack()

Perhaps I should have called this "cursor problem."  On further
investigation, I disabled the command button while the page is being
retrieved, and this works even though the cursor change does not.  So now
I've got the following code:

class Application(Tkinter.Frame):
    def __init__(self):
        self.b = Button(self, text="Retrieve Page",
command=self.my_slow_method)
        self.b.pack()

    def my_slow_method(self):
        self['cursor'] = 'watch'
        self.b['state'] = DISABLED
        self.update_idletasks()
        retrieve_page_from_wiki()     # placeholder function
        self['cursor'] = ''           # reset to default
        self.b['state'] = NORMAL

While the page is being retrieved from the server, the button is disabled,
but the cursor remains normal.  Is this a Windows problem, or is there
something I can do within Tkinter to get the
cursor to behave as desired?

You can create a global or better: a class Flag that gets switched on whenever a toplevel windows becomes active.

Subject: [Tkinter-discuss] tag_bind causes memory leak; fix?
Message-ID: <48311.68.34.179.248.1149976254.squirrel@webmail.brynmawr.edu>

Tkinter users,

I have a Tkinter app that redraws objects on a canvas, about 10 times a
second. It doesn't reuse the drawn objects, it just draws and deletes.

In order to make it so that we can click on these objects, we have code like:

self.simulator.canvas.tag_bind("robot-%s" % self.name, "<B1-Motion>",
   func=lambda event,robot=self:self.mouse_event(event, "motion", robot))

for each object (a robot). First, is there a better way than doing this
after every object creation?

One problem with this method is that it appears to cause a memory leak.
Trying to unbind these, like:

self.simulator.canvas.unbind_all("<B1-Motion>")

or this method:

self.simulator.canvas.tag_unbind("robot-%s" % self.name, "<B1-Motion>")

doesn't seem to help. Any ideas on a better way, or how to stop the memory
leak?

Thanks!

-Doug

I'd recommend using a canvas-level binding instead, and using 
find_overlapping to find the appropriate object for each mouse event.
e.g.

      def motion(event):
          widget = event.widget
          x = widget.canvasx(event.x)
          y = widget.canvasy(event.y)
          d = 5 # overlap, in canvas units
          items = widget.find_overlapping(x-d, y-d, x+d, y+d)
          if items:
              ... process items; topmost is last ...

      canvas.bind("<B1-Motion>", motion)

(I'd also recommend using a WCK view instead of the Canvas for this 
purpose, but that won't help you with the bindings issue).

Excellent! This solved the "momery leak" and is much more efficient (so
that we don't have to rebind these events to new objects 10 times a
second). I have posted my adapted solution below. The only sticking point
was that this method doesn't have state about what you were clicking on.
Actually, now that I say that, I'm not sure why it worked before with
object-level bindings.

When it comes time to rewrite this, I will carefully look at WCK. For now,
this is just a very important bug fix (was losing about a megabyte of
memory a second).

Thanks again!

Subject: [Tkinter-discuss] animated gif
Message-ID: <4491A6C9.4040905@post.cz>

Hi all,

How to animate an animated gif? I made some trials, using metod seek() 
on instance of Image.open, cause I believe Tkinter can not do this 
itself, but no success. My gif got 2 frames, and the second one is 
always more or less black.

This script is not "animated", just want to show my approach to the problem:

from Tkinter import *
from PIL import Image, ImageTk

hlavni=Tk()
platno=Canvas(hlavni)
platno.pack()

image = Image.open("myani.gif")
frames=[]
for frame in range(2):
    image.seek(frame)
    frames.append(ImageTk.PhotoImage(image))

platno.create_image(50,50, image=frames[0])
platno.create_image(100,100, image=frames[1])

hlavni.mainloop()

Thank you all for any suggestion.

1.  I wrote a gif animator for Tk:  <URL: http://wiki.tcl.tk/anigif >.
2.  While I'm busy today, maybe on the weekend I'll adapt it to
    Tkinter and comment on what you've written.

Not sure exactly what a Qt tab-bar is. If you mean something like the bar on the top of your web browser that uses buttons w/ icons then you'll have to make a bar using a frame in Tkinter. Luckily this is not hard to do with Python/Tkinter.

Hi all,

 

I am using keyboard to send the parameters to my functions.
(event.keysym), but some of the keys are not working. Those are +, - and
Break. The keysym for those keys in Tkinter book are defined as Add,
Subtruct and Cancel .  Is there anyone else who knows the correct
symbols?

 

Thanks,

plus, minus, and Cancel sounds more likely.

here's a little program that prints the keysym when you press a key:

	import Tkinter

	def callback(e):
	    print e.keysym, repr(e.char)

	w = Tkinter.Frame(width=512, height=512)
	w.bind("<KeyPress>", callback)
	w.focus_set()
	w.pack()

	w.mainloop()

Subject: [Tkinter-discuss] creating widgets generically, with a loop?
Message-ID: <20060620164037.64147.qmail@web33112.mail.mud.yahoo.com>


Some background info: I have a Python/Tkinter script that displays a
dialog with buttons, where each button launches a file for editing.
Sort of like an HTML file in a browser, except with my script I can
launch it using a particular program.

I've been trying to figure out a way of storing widget information
(name of each widget, x and y positions, and a command to execute
when activated) in an array so I can generically create each widget
instead of hard-coding all the information. For example, here's a
snippet of what I currently use:

    ...
    Button(top, text="OO design info",
command=self.launch_file23).grid(sticky="w",row=10,column=5)
    ...

    ...
    def launch_file23 ( self ): os.spawnl ( os.P_NOWAIT , 
"c:\\Program Files\\TextPad 4\\TextPad.exe" , "TextPad.exe" , "d:\\My


Documents\\prog_oo_design.txt" )
    ...

If there was a way I could pass arguments to launch_file23 from the
"command=" parameter, that would solve the problem nicely - I could
store the info in an array, and then just loop to create the buttons.

Any ideas?

This confuses me.

I'm trying to catch up on a few loose ends; I'm in arrears by 
weeks.  I've re-read this thread, and I still don't understand the
aim.  I'm confident, though, that there are easier ways to meet
the true requirements.  Is the intent to work with Buttons, or
Menubuttons?  It's quite unusual to need to bind conventional
events to Buttons; it's more typical to rely on .command.

My suggestion:  simplify your question down to a more "atomic" 
one.  There are too many things going on in the code above for me
to understand.

No.  Well, yes.  Sort of.  The Tk tradition, on which Tkinter
largely is built, is to code in terms of "notebook" widgets
<URL: http://wiki.tcl.tk/notebook >.  An example appears here:
<URL: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/188537 >.
PMW has a notebook, and there are several others.

An idea using subclassing of 'Button':
--------------------------------------------------
from Tkinter import *

class ButtonParam ( Button ):
	def __init__ ( self, param, parent, **kw ):
		Button.__init__ ( self, parent, kw )
		self.Param = param
	def launch ( self ):
		print 'My Param:', self.Param

if __name__ == '__main__':
	tk = Tk ()
	for bspec in [('text1','par1'),('text2','par2'),('text3','par3')]:
		b = ButtonParam ( bspec [1], tk, text=bspec [0] )
		b.configure ( command=b.launch )
		b.pack ()
	tk.mainloop ()
------------------------------------------------------------------

Perhaps the parameters to __init__ need additional tweaking
and you might want more than one parameter.

Hope this helps,

Perhaps:


my_buttons = [
## fullpath names should be used here but for the sake of wrapping
   ("OO design info", "TextPad.exe", "oo_design.txt"),
   ("AA design info", "TextPad.exe", "aa_design.txt"),
   ("ZZ design info", "TextPad.exe", "zz_design.txt"),
]


def launchit(external, filename):
   external_short = os.path.split()[1]
   def real_launchitit():
       os.spawnl(os.P_NOWAIT, external, external_short, filename)
   return real_launchit

for text, external, filename in my_buttons:
   b = Button(self, text=text, command=self.launchit(external, filename))
   b.grid()

Subject: [Tkinter-discuss] application busy problem
Message-ID: <44991AB2.3080205@gmail.com>

Hi,

I'm using Tkinter to create an application which parses some huge text 
files (from 50kb to 120Mb). When the files are being parsed, I would 
like to forbid the user to do anything else and to show the application 
is busy(like an icon that turns over itself), because when he clicks on 
anything, the application fails.

Does this work - does the "command=" parameter allow the function
value to contain parameters too? If so, it would solve the problem
easily!

the code *calls* the given method, and passes the return value (in this 
case, an instance of the inner function) to the Button constructor.

While I've largely lost track now of who said and/or wants what,
it *is* true, though, that .command can be parametrized, at a
couple of different level, if that's what's required.

that's what martin's example does, of course -- mike appeared to think 
that the command=foo(bar) syntax meant that "foo" was a callback, rather 
than a function producing a callback.

Hi Olivier,

you probably want a dialog window that grabs all events:

    top = Toplevel()
    top.transient(rootwindow)
    top.grab_set()
    Label(top, text="Computing, please wait...").pack()

The call to transient() makes the dialog always stay on top of the application's root window,
grab_set() prevents any events from being delivered to other windows in your app.

I hope this helps

Michael

Subject: [Tkinter-discuss] Mouse wheel event for Canvas
Message-ID: <1150950286.5055.12.camel@kuepper.vels-int.com.au>

I tried binding mouse wheel events (<Button-4>, <Button-5>) to a Tkinter
Canvas widget with the hope of using the event.delta value to
subsequently scroll the Canvas.

However, it seems that event.delta always returns 0.

For example,

from Tkinter import *

r = Tk()
c = Canvas(r, scrollregion=(0,0,500,500), height=200, width=200)
s = Scrollbar(r, command=c.yview)
c.pack(side=LEFT)
s.pack(side=RIGHT, fill=Y)
c.configure(yscrollcommand=s.set)
c.create_rectangle(10,10,100,100)
c.create_rectangle(10,200,100,300)

def rollWheel(event):
    print event.delta

c.bind('<Button-4>', rollWheel)
c.bind('<Button-5>', rollWheel)

c.focus_set()

r.mainloop()


Has anyone successfully managed to wheel scroll a Tkinter Canvas
widget ?

Regards,

John

Mike,


Sorry I should have provided some doc strings ;)  The magic in my
example is here:-

## this function is called when you create the Button widget
def launchit(external, filename):
    external_short = os.path.split()[1]

    ## this inner function has access to the outer functions 	
    ## namespace
    def real_launchit():
        os.spawnl(os.P_NOWAIT, external, external_short, filename)

    ## return a reference to the inner function
    ## this 'reference to a function' will be called when the button
    ## is pressed
    return real_launchit


on re-reading the example I noticed I had made a couple of typoes

Cheers
Martin

Thank you for answering me Michael,

Maybe my question is not well asked :

Is it possible to launch an other thread, for example :

- at the beginning of the application, before all the needed imports, a 
small window appears and displays informations or animations (gif) ?
- the same thing when application is working, this time without hiding 
tha main window, but by inserting a small gif in the corner of the 
application.

It works!

Thanks for your help. I've included the complete (it's small) source
file below, in case anyone's curious.

----- start of .py file -----

import os
from Tkinter import *

class App:
    def __init__( self , top ):
        top.geometry ( "+0+0" )

        my_buttons = [ ( "button_text1" , "program_name1" ,
"file_name1" , 1 , 0 ) , ( "button_text2" , "program_name2" ,
"file_name2" , 0 , 1 ) ]

        for text , external , filename , row , col in my_buttons:
            b = Button( top , font=("Verdana",7) , pady=0 ,
borderwidth=0 , text=text , command=self.launchit(external,filename)
)
            b.grid( sticky="w" , row=row , column=col )

    ## this function is called when you create the Button widget
    def launchit ( self , external , filename ):
        external_short = os.path.split( external )[1]

        ## this inner function has access to the outer functions 	
        ## namespace
        def real_launchit ( ):
            os.spawnl ( os.P_NOWAIT , external , external_short ,
filename )

        ## return a reference to the inner function
        ## this 'reference to a function' will be called when the
button
        ## is pressed
        return real_launchit

root = Tk()
app = App(root)
root.mainloop()
----- end of .py file -----

I worked it out.

c.bind('<Button-4>', lambda event: event.widget.yview_scroll(-1, UNITS))
c.bind('<Button-5>', lambda event: event.widget.yview_scroll(1, UNITS))

I also changed the yscrollincrement to '5p'.  The default moved a bit
too much.

Hi John,

here is a code snippet I have successfully used:

        self.canvas.bind('<4>', lambda event : self.canvas.xview('scroll', -1, 'units'))
        self.canvas.bind('<5>', lambda event : self.canvas.xview('scroll', 1, 'units'))

or if you do not like the lambda, you can use a callback like this:

    def rollWheel(event):
        if event.num == 4:
            self.canvas.xview('scroll', -1, 'units')
        elif event.num == 5:
            self.canvas.xview('scroll', 1, 'units')

I hope this helps

Michael

Do you mean some kind of "splash screen"?
In this case try something like this:

from Tkinter import *
root = Tk()
root.withdraw()
splash = Toplevel()
# fill the Toplevel with other widgets and perform
# other maybe time consuming things
splash.destroy()
root.deiconify()

then you will have to disable all the widgets in the main window that might cause
problems if the user clicks on them. For the "busy" icon you could use a Label
and set its "image" option to the empty string when the process has finished to make the icon disappear.

I hope this helps

Subject: [Tkinter-discuss] Button Overrelief
Message-ID: <44A11B4F.2030601@pcblokes.com>

Hello all,

I have some Tkinter buttons that display images. I would like to change
these to 'active' images when the mouse is over the button.

I see that the button widget can take an 'overrelief' argument in the
constructor. What values can this take ?

Also - can anyone provide an example of using the equivalent of a
'mouseover' event to change the image used by a button in Tkinter ? I'm
afraid google has not helped me much here.

Much Appreciated,

same as RELIEF; see

you can use <Enter> and <Leave> events for this; see:

Thanks for your help Fredrik, this is working great. I'll have to 
experiment with RELIEF and OVERRELIEF.

All the best,

Subject: [Tkinter-discuss] Iterate Scale widgets
Message-ID: <20060630120013.2pafjg10gg808g0o@maroon.cudenver.edu>

The problem with the following program is I am not able to get values 
corresponding to each scale widgets. I tried initially storing the 
scale widget names in a list and then get the values but did not work. 
So, I borrowed the trace variable part of the script from some internet 
source. In the program below all the scale widgets created are having 
the same variable ?var?, how do I change the variable names 
automatically or is there any other way to retrieve the values of 
scales? Any advice will be appreciated.
Thank you,
Reema

from Tkinter import*
import sys, Tkinter, types, copy
root = Tk()

i = 1
k = 5

var = Tkinter.DoubleVar()
oldvalue = var.get()

def callback(*args):
    global oldvalue
    #An exclamation point tells var that what follows is a Python 
statement, not a var command.
    if var.get() != oldvalue:
        oldvalue = var.get()
        print var.get()

var.trace_variable("w", callback)
        while i<=k:
    j=1
    var1 = var + i
    while j<=k:
        Scale(root, from_ = 0.0, to = 1.0, resolution = 0.1, variable = 
var, orient = 'horizontal').grid(row=i,column=j)
        j=j+1
    i=i+1
root.mainloop()
