Hi,
i’ve encoutered this issue using wxPython 3.0.

I add a wxpython widget and when i init the frame i get the following error :

wx._core.PyAssertionError: C++ assertion “m_window” failed at …/src/gtk/dcclient.cpp(2043) in DoGetSize(): GetSize() doesn’t work without window

Have you a solutioon ?

Thanks in advance,

Antonio.

Nothing comes to mind given that description. Sample code would
help.

I was working with richtext widget and I used this line to get the size :
size= self.m_richText.GetClientSize()

That's not enough code. The implication from the error is that you
tried to do this before the window had been created, or after the window
had been destroyed. A window doesn't get created immediately; the
constructor fires off some window messages that eventually set up the UI
structures. Where are you making that call?
