Cannot use Widgets in wx.Listbook

wxPython Users
#1

Hey, so i want to creat a settings menu.

For that purpose i use a wx.Listbook and fill it up with panels. The panels are all seperate classes. The change between the panel works. But when i put some widgets on the panels like Buttons or checkboxes, they are not usable. I cannot click them or anything. I have a minimum viable example here that might help to understand the problen.

try to go from simple to less simple, not from complex to void :upside_down_face:

Thanks for your help but could you be a bit more specific? I dont understand exactly what you mean.

Hi,

Simplification always helps you guess the cause of the problem.
You can remove even more irrelevant sizers and panels.

Anyway, this kind of problem is due to bad parents. In your case, the settingsABC object must have settingsBook as the parent. So, modify as follows.

-        self.settingsBook.InsertPage(2, settingsABC(self,self.panelSize), "ABC")
+        self.settingsBook.InsertPage(2, settingsABC(self.settingsBook,self.panelSize), "ABC")

Thanks. That indeed worked.

I also found another way in the meantime. I just instanciate the widgets directly from the class instead of creating new classes for every page.

Thanks. It worked positively
