[issue39642] Behaviour of disabled widgets: widget.bind(func) -vs- w = widget(command=func)

[Clinton Hunter]

New submission from Clinton Hunter <mrshr3d at gmail.com>:

Using the bind method, the event will still trigger when the widget is disabled.  However, if using "command=" it doesn't.  Wondering whether the behaviour between the two ways of setting up event handling should behave the same?  Not a major issue, easy enough to work around using an if.

Example:

Clicking the printBtn will still work despite being disabled.

self.printBtn = tkinter.Button(self.frame, text='Print')
self.printBtn['state'] = tkinter.DISABLED
self.printBtn.bind(sequence='<Button-1>', func=self.printBtn_onclick)
self.printBtn.pack()


Clicking on the save button, the event will not trigger (ie the disabled state attribute is honored)

self.saveBtn = tkinter.Button(self.frame, text='Save', command=self.saveBtn_onclick)
self.saveBtn['state'] = tkinter.DISABLED
self.saveBtn.pack()
