I was making a wxPython calculator UI using wxFormBuilder I can't put wxPanel in wxFrame. .. ..
I thought it was a wxPanel It seems that overseas Aniki was also worried about the same thing. Looking at the answer to that question, one screenshot ...
That was the case. It was a Panel, not a wxPanel. I misunderstood it because it is in Forms with Frame. So where is the correct wxPanel? ??
It was in Contains.
I'm not the only one who makes such a mistake. .. ..
