MyWorld in hello world example has no __init__ function

[enjoysmath]

In particular python complains because the base class init expects a self (hidden first param). So I wrapped it in an init() method and it works, except:

adding: Panda3DWorld.init(self, width=1024, height=768)

The preffered width / height has no effect.

Hi, in QPanda3D, we use QWidgets (QPanda3DWorld). In this case, as any Qt widget, you depend on the layout in which the widget is placed. Refer to setSizePolicy and setFixedWidth and setFixedHeight methods to learn how to force a fixed widget size. QPanda3D is a wrapper that links Panda3d to the Qt world.
