SimpleGL

This is a Simple class extending the DrawingArea widget. A really simple Demo illustrating OpenGL with DUI It uses the new GLCapability mixin to add the GL capabilities to the widget. This example is provided under the terms of the GPL License. Note the initialization of the GLCapabilities on the constructor.

Functions

drawGL bool drawGL(GdkEventExpose* event): This method is called every time the window must be paint or repaint This is where you put the OpenGL call to draw something. This method call be called directly by the application without an event object to force redrawing of the scene. returns true to consume the event
initGL bool initGL(): put any gl initializations here returns true to consume the event
resizeGL bool resizeGL(GdkEventConfigure* event): This method is called when the window is resized returns true to consume the event

Mixins

__anonymous mixin GLCapability: need to include the mixin to add GL capabilities to this widget

gtkDrawingArea GtkDrawingArea* gtkDrawingArea;: the main Gtk struct
getDrawingAreaStruct GtkDrawingArea* getDrawingAreaStruct(): Undocumented in source. Be warned that the author may not have intended to support it.
getStruct void* getStruct(): the main Gtk struct as a void*
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
size void size(int width, int height): Warning gtk_drawing_area_size is deprecated and should not be used in newly-written code. Use gtk_widget_set_size_request() instead. Sets the size that the drawing area will request in response to a "size_request" signal. The drawing area may actually be allocated a size larger than this depending on how it is packed within the enclosing containers.
