Base Classes

PtWidget <-- PtBasic <-- PtLabel <-- PtButton

Description

This widget is a button that can be used to initiate actions in Gamma, usually through callbacks. When a button is pressed (the mouse button is held down on it), it is armed, and its color becomes shaded. As a child of the PtLabel class, a PtButton inherits the label_type variable, which allows you to put text strings, images, and bitmaps on it. What's more, you can have a PtButton change its color or image when it is armed, by setting its own instance variables.

Note

For detailed information, please refer to PtButton in the Photon documentation.

Instance Variables
