I ran into exactly this keyboard shortcut issue while writing the Rapyd-Tk
Python development environment (http://www.bitflipper.ca/rapyd/). My solution
is based on these functions, where the left part is the usual menu label and
the right part is the shortcut. If the length of the shortcut text varies a lot
you can compute the width on the fly as is done in Rapyd, otherwise just use
some reasonable constant.
def PadToWidth(LeftPart,RightPart,Width,Widget):
"""
Given left and right parts, return string of specified width in pixels.
o "LeftPart" is the string to be left justified in the result.
o "RightPart" is the string to be right justified in the result.
o "Width" is the desired width, in pixels, of the result.
o "Widget" the calculation is done with reference to the font set for this
widget.
Note that since we pad with space characters, the result will be as close as
possible to the target size but will not necessarily be exactly the
number
of pixels requested.
"""
UsedPixels = TextMeasure(LeftPart+RightPart,Widget)
PadPixels = Width - UsedPixels
PadCount = int(round(float(PadPixels) / float(TextMeasure(' ',Widget))))
return '%s%s%s'%(LeftPart,' '*PadCount,RightPart)
def TextMeasure(Text,Widget):
"""=u
Measure size of "Text", in pixels, if displayed in "Widget".
"""
return int(Widget.tk.call("font", "measure", Widget["font"]
,"-displayof", Widget.master, Text ))

Also, I have set keyboard shortcuts for some functions in my program.
The functions these shortcuts call are also linked to menu items in the
menu bar. How can I get the menu labels to reflect the keyboard
shortcuts for each relative command? I know I can set the shortcut as a
string in the label manually, but it will be stupid, not flush with the
right edge of the menu, like in other programs.
Thanks for helping my program not be stupid
