Re: [Visualpython-users] a few simple questions about remove / clear ...

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

 From the section of the help titled "Deleting an object" there is this:

To delete a Visual object just make it invisible: ball.visible = 0

Technical detail: If you later re-use the name ball, for example by 
creating a new object and naming it ball, Python will be free to release 
the memory used by the object formerly named ball (assuming no other 
names currently refer to that object).

(If you simply make an object invisible, you might later make it visible 
again. But if you reassign the name, there is no longer any way for your 
program to access the object, so its memory can be released.)

Similarly, a display such as scene can also be made invisible 
(scene.visible = 0), and if its name is reassigned the memory is released.

If on the other hand you want to keep the window visible but remoe all 
objects from it, you need to make all the objects in the display 
invisible. In the section titled "Controlling Windows" there is this 
note about how to get at all the (visible) objects in a display:

objects A list of all the visible objects in the display; invisible 
objects are not listed. For example, this makes all boxes in the scene red:

    for obj in scene2.objects:
    if obj.__class__ == box # can say either box or 'box'
        obj.color = color.red
