Detailed Description

Represents an OpenGL context, possibly a widget or a pbuffer, which can also respond to keyboard, mouse or system events.

OpenGLContext is an abstract class that wraps a minimal common subset of GUI APIs like Win32, Qt, wxWidgets, SDL, GLUT, etc.
In order to respond to the events generated by the OpenGLContext you must subclass an UIEventListener and bind it to the OpenGLContext using the functions addEventListener(ref<UIEventListener>) and removeEventListener(ref<UIEventListener>).

OpenGLContext Custom Implementation
  • Key_Alt/Ctrl/Shift events must always be notified before Key_Left/Right-Alt/Ctrl/Shift events.
  • Always update the mKeyboard structure appropriately especially with respect to Key_[Left/Right]-Alt/Ctrl/Shift events.
  • When cycling through EventListeners to dispatch the events you must do it on a temporary copy of mEventListeners so that the EventListeners can safely add/remove themselves or other EventListeners to the OpenGLContext itself.

vasThe IVertexAttribSet to be activated. It can be NULL, in which case all vertex attributes are disabled. If vas is the same as the last activated IVertexAttribSet then no operation is done.
use_vboWhether vertex-buffer-objects should be used when activating the vertex attributes.
