[wxPython-users] GridBagSizer error with a hidden item

[Lee Merrill]

Well, I found out what I need to do after hiding or showing a control, I ca=
ll Layout on that control, then for that window and for every parent window=
, I call Layout on the window's sizer and containing sizer, and that seems =
to work. Snippet follows...

Just FYI,
Lee

        szrList =3D []

        def showCtrl(ctrl, show=3DTrue):
            if show:
                ctrl.Show()
            else:
                ctrl.Hide()
            ctrl.Layout()

            prevSzr =3D None
            while ctrl:
                szr =3D ctrl.GetContainingSizer()
                if not szr:
                    break
                if not szr in szrList:
                    szrList.append(szr)
                szr =3D ctrl.GetSizer()
                if szr and not szr in szrList:
                    szrList.append(szr)
                ctrl =3D ctrl.GetParent()
                prevSzr =3D szr

                # Lots of hides / shows via showCtrl() above, and then...

        for szr in szrList:
            szr.Layout()
        Root.Layout()
