GLWidget

Description GtkGLExt is an extension to GTK which adds OpenGL capabilities to GtkWidget. Its use is quite simple: use gtk_widget_set_gl_capability to add OpenGL support to a widget, it will create a OpenGL drawable (GdkGLDrawable) for the widget, which can be obtained via gtk_widget_get_gl_drawable. OpenGL rendering context (GdkGLContext) can also be obtained via gtk_widget_get_gl_context. With GdkGLDrawable and GdkGLContext, gdk_gl_drawable_gl_begin and gdk_gl_drawable_gl_end can be called, and OpenGL function calls can be made between those two functions.

class GLWidget {

static GLDrawable getGLDrawable(Widget widget);

static int setGLCapability(Widget widget, GLConfig glconfig, GLContext shareList, int direct, int renderType);

static int isGLCapable(Widget widget);

static GLConfig getGLConfig(Widget widget);

static GLContext createGLContext(Widget widget, GLContext shareList, int direct, int renderType);

static GLContext getGLContext(Widget widget);

static GLWindow getGLWindow(Widget widget);

createGLContext GLContext createGLContext(Widget widget, GLContext shareList, int direct, int renderType): Creates a new GdkGLContext with the appropriate GdkGLDrawable for this widget. The GL context must be freed when you're finished with it. See also gtk_widget_get_gl_context().
getGLConfig GLConfig getGLConfig(Widget widget): Returns the GdkGLConfig referred by the widget.
getGLContext GLContext getGLContext(Widget widget): Returns the GdkGLContext with the appropriate GdkGLDrawable for this widget. Unlike the GL context returned by gtk_widget_create_gl_context(), this context is owned by the widget. GdkGLContext is needed for the function gdk_gl_drawable_begin, or for sharing display lists (see gtk_widget_set_gl_capability()).
getGLDrawable GLDrawable getGLDrawable(Widget widget): Gets the GL Frawable for (from???) the widget
getGLWindow GLWindow getGLWindow(Widget widget): Returns the GdkGLWindow owned by the widget.
isGLCapable int isGLCapable(Widget widget): Returns whether the widget is OpenGL-capable.
setGLCapability int setGLCapability(Widget widget, GLConfig glconfig, GLContext shareList, int direct, int renderType): Set the OpenGL-capability to the widget. This function prepares the widget for its use with OpenGL.
