PGItem

from panda3d.core import PGItem
class PGItem

Bases: PandaNode

This is the base class for all the various kinds of gui widget objects.

It is a Node which corresponds to a rectangular region on the screen, and it may have any number of “state” subgraphs, one of which is rendered at any given time according to its current state.

The PGItem node must be parented to the scene graph somewhere beneath a PGTop node in order for this behavior to work.
