Serhiy Storchaka added the comment: This is not Tkinter bug, this is normal Tk behavior. Here is minimal reproducer on Tcl/Tk :
button .b -text "Click me" bind .b <Button-1> {tk_messageBox -message "The button is sunken!"} pack .b I suppose the button is left sunken because the message box steals a focus. In general binding mouse click event for button is not a good idea, because it makes a button non-usable with keyboard. Use the "command" option. ---------- nosy: +serhiy.storchaka resolution: -> not a bug _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11387> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
