Win_OpenGL_Base.T is a subtype of \type{GraphicsBase}{T}. An object of this type provides an abstract interface to Microsoft Windows NT and OpenGL.

INTERFACE Win_OpenGL_Base;

IMPORT GraphicsBase;

TYPE
  T <: Public;
  Public = GraphicsBase.T OBJECT
  METHODS
    init (title : TEXT; win_x, win_y := 10; win_w, win_h := 500) : T
        RAISES {GraphicsBase.Failure};
    changeTitle (title : TEXT);
    awaitDelete ();
    destroy ();
  END;
gb.init initializes a new graphics base and returns it. As a side effect, it creates a window win_w by win_h pixels in size, and win_x,win_y pixels offset from the upper left corner of the screen.

gb.changeTitle(title) changes the title of the window associated with gb to title.

Calling gb.awaitDelete () suspends the calling thread until the window associated with gb gets destroyed.

Calling gb.destroy() destroys the window.

PROCEDURE Available () : BOOLEAN;
Available() returns TRUE if OpenGL is supported on the host machine.

END Win_OpenGL_Base.
