Hi folks, I have a GUI and I want to redraw/refresh all the GUI elements/widgets when the user wants to switch to its own regional language. Any tools with Tkinter, or any idea outside Tkinter. Thx Andrewerol
Wondering if there's a 3rd party Tkinter or Tk library or a general programming technique that would allow one to create Tkinter based applications with panels that can be docked, undocked, and resized (while docked and undocked)? Here's an example of what I'm talking about. This is a short 1 minute screencast of a wxPython based framework called Dabo demonstrating the capabilities that my users have asked for. http://screencast.com/t/3qRgqHsJVbK I'm using Python 2.7 under Windows and have noticed that Tkinter appears to have some built-in concept of docking when TopLevel windows are moved around the desktop. Is there a way to trap these Tkinter docking events and use Tkinter's built-in docking behaviors to implement this type of functionality? Regards, Malcolm

I don't think Tk has support for this, either as a library or a core function. You can fake it using various techniques, but it would be a lot of work. -- -- Kevin Walzer Code by Kevin http://www.codebykevin.com
Hi all, I need scroll 3 Text widgets with one scrollbar. All is packed into grid [text, text, text, scrollbar] all Text widgets have font on same size how i scroll all 3 widgets 'synced' using scrollbar ? i have a method which is scrollbar.command def update_widgets(self, *args): # scrolling all 3 widgets for win in self.textwindows: win.yview_moveto(args[1]) this scrolling widgets but after few 'slides' rows are not synced :( and second question is 'how i set next 2 widgets and scrollbar if i scroll some widget using keyboard? ' i think it must be something like scrollbar.set(*args) in widget.yscrollcommand but i'm trying without luck. thanks

I'd replace this with something like:
def update_widgets(self, *args):
for win in self.textwindows:
win.yview(*args)
If this still doesn't work properly, i would try and add an
update_idletasks() to the function. At least here this does not seem to
be necessary though.

Thanks this helps a lot.
Your code for keypress looks like you call internal Tcl/Tk commands ?
Seems like my for mousewheel.
But <MouseWheel> dont generate any signal i must use Button-4 and
Button-5 on linux.
def mousewheel_cb(event):
direction = 1 if event.num == 5 else -1
for win in self.textwindows:
win.yview('scroll', direction, 'units')
this working nice.
Hi again,
I write simple hexedit for my home use and i searching solution for
setting some spaces between chars in Text widget. Something like
'spacingN' for Y. Exists ? I dont want to insert extra space between
chars like now.
i have 16bytes on line in {0:02X}format.

can i make this without spaces ?
thanks

At a second glance my example isn't so nice either, because it does not
only sync the yview but also the cursor position, which is most likely
not wanted. However this can be easily fixed by restoring the "slave"
widget's cursor position with something like:
def down(event):
oldinsert = slave[event.widget].index('insert')
root.tk.call('tk::TextSetCursor', slave[event.widget],
root.tk.call('tk::TextUpDownLine', event.widget, 1))
slave[event.widget].mark_set('insert', oldinsert)
Doing this for lots of event sequences is quite a pita though, maybe
wrapping it like this is a bit better:
slave = {t1: t2, t2: t1}
def callback(textwidget, *args):
oldinsert = slave[textwidget].index('insert')
root.tk.call(*args)
slave[textwidget].mark_set('insert', oldinsert)

Yes, as I said these commands are defined in text.tcl (on linux this can usually be found at /usr/lib/tk8.x or so), and the widget.tk.call() mechanism is the magic that allows us to access Tcl/Tk's internal commands from Python. Once you understood how to handle Tcl/Tk commands from Python it is quite straightforward and a great and powerful way to enhance Tkinter's capabilities, so I absolutely recommend to have a closer look at it ;) A great way to learn using tk.call() is to compare for example the button widget's tcl man page (just try "man button") with the code from "class Button" in Tkinter.py, you will easily see how this works. > > Seems like my for mousewheel. > > But <MouseWheel> dont generate any signal i must use Button-4 and > Button-5 on linux.
