Hello,

I have a program that runs inside a tclkit (windows exe). Whenever I
close the program by clicking the "X", the tclkit still says its running
the task manager. Are there any tips on how to properly close a tclkit?
Right now, I simply have an exit command binded to the window.

Thanks,

 
Try adding:
 
wm protocol . WM_DELETE_WINDOW ::exit
 
Note:  is "." the only toplevel?  Is that in fact the toplevel you are
closing?
 
Have you done something like this?
 
wm withdraw .
 
toplevel .mytoplevelui

Hi Robert,
 
Thank you for your recommendation. You were right, I had a separate
toplevel that was not necessary. Also,
 
wm protocol . WM_DELETE_WINDOW ::exit
 
Appears to be the better way than binding exit to the destroy callback.

Right. The WM_DELETE_WINDOW is what is bound to the 'X' or "Close" menu item
in the window manager supplied menu.  The destroy binding happens when the
window is actually destroyed, which is actually something different (and not
actually something the window manager does).

I know that people no longer want to include an explicit "Exit" or "Close"
feature in GUIs anymore, and instead are passing that buck to the window
manager, since WM's (always under MS-Windows and MacOSX, by default with
"modern" Linux desktops) are now providing a "standard" close option.  But,
*I* always do things old-school and provide an explicit "Exit" or "Close"
feature: an Exit/Close [toolbar] button or Edit and/or Close on the File menu.

 
Thanks,
 
Jacob
