TGLWidget Class Reference

GL window with context.

Must have a parent window (the 'parent' parameter of ctors). The current version inherits TGCanvas (I'm not sure about future versions), probably, in future multiple inheritance will be added - the second base class will be TGLPaintDevice or something like this.

Usage:

Resources (and invariants):

Exceptions:

TGLWidget object is immutable as far as it was created.

Boolean parameter defines, if you want to grab user's input or not. By default you want, but for example when not - see TGLPShapeObjEditor.

Non-copyable.
