Re: [Visualpython-users] Text disappears after hiding the scene ...

[Bruce S. <Bru...@nc...>]

But "hide" IS supported. It's unfortunate that there was a scene.hide() 
that was undocumented (and not implemented in Visual 5), but it has 
always been the case that scene.visible = False has worked in all 
versions of Visual.

Nor am I sure that I understand what is meant by "resize not allowed 
during visible". Do you mean setting scene.width and scene.height? That 
didn't work in Visual 3, either. The following resizing works in both 
Visual 3 and Visual 5:

from visual import *
box()
scene.mouse.getclick()
scene.visible = False
scene.width = 800
scene.visible = True
