Detailed Description

Group of bitmaps that are rendered into the same X-window.

A RenderGroup instance is indentified uniquely by an x-window id.

Constructor & Destructor Documentation

Default constructor.

Parameters

display_id	Pointer to x display id
glc	Reference to GXLContext
window_id	X window id: used as an id for the render group
child_id	X window id: this is the actual render target. Can be the same as window_id.
doublebuffer_flag	Use double buffering or not (default true)

bool RenderGroup::addContext ( RenderContext * render_context )

in this x window)

Set current x window to RenderGroup::window_id
Set viewport
Clear drawing buffer
Run over RenderGroup::render_contexes and call each one's RenderContext::render() method
