Issue with Tkinter Dialog

[psbasha]

Hi,

I have created a Simple Dialog with ComboBox and Radio buttons.When I execute my UI source code.I am able to see the dialog .When I Close the Dialog,I am not able to edit the source code for the dialog.I have to go to the task manager and kill the PythonWin.exe and restart the PythonWin and work on the UI modifications.

Whether anybody has faced the similar problem,If so ,your help will be really appreciated

Thanks

You must

myDialog.destroy()

dialogs when you are done with them.

Forum stuff:
You need to put "Tkinter" into your post titles. For example, in wxPython, it's

myDialog.Destroy()

so please help us help others. Thanks.

Hi,

First time when I execute the UI source code ,I am able to see the Dialog.When I close the dialog,and execute the Source code without closing the PythonWin IDE,I am not able to see the Dialog.To see that I have to close the application thru Task Manager by killing the "PythonWin.exe"


Thanks

If you have destroy()ed the dialog and you are still having the problem, it may be because your tools don't work very well. The IDE should spawn a thread (new python instance in task manager) and run your program there, thereby having much greater control over the software under development.

In Tkinter -

What is the callback/handler function to be called for the "window closing", i.e "X" symbol shown at the right top location of the dialog.

In Tkinter:

I hope the close event method/callback ,will solve the problem.Since I am using the close button,no method has been written to destroy the window.

Could anybody suggest the piece of code for closing the window.

While debugging the Dialog code,when we close the Dialog window the debug mode of the code has to come out.Even if I press Shift+F5,the debug mode is not stopped.I have to kill the PythonWin.exe

That's why it's called a "snippet": for example only.

What I do is debug a dialog entirely on its own (just like a top level window), then call the WORKING dialog from the application. Like so:
create the dialog in a single module
at the bottom of the module add

if __name__ == "__main__":
    root = Tk()
    testDialog = TheDialogClassUnderTest(root)
    testDialog.pack()
    root.mainloop()

then you can import your working dialog into your application.
