Yeah, there will be a demo to the TGLXComponentEngine, i'm however doing a total remake of the engine and it takes much time to get it really powefull.

The new version vill support dragging, layered components, windows, panels, copy+paste etc.

Currently i have finished the TGLXButton, TGLWindow, TGLXPanel, TGLXLabel, TGLXEdit and is currently working on TGLXScrollbar to be used in memo components etc.

If you like to se an implementation of the old componentengine download ZHess from the download section of NeHe (http://nehe.gamedev.net/). It's a game i have written that uses the componentegine for the menus and more.
