class glWindow

OpenGL window class This class implements everything needed to create and use a OpenGL context under OS/2

Public Methods
inline long ActiveBuff(): Return active buffer
bool Bind(HWND winHandle): Bind OpenGL buffer to a PM window, either client or frame window
inline long BufferHeight(): Return logical buffer height
inline long BufferWidth(): Return logical buffer width
virtual MRESULT ClientMessage(ULONG Message, MPARAM MsgParm1, MPARAM MsgParm2): Two virtual functions that performs PM message management for frame and client
inline void Command(ULONG CommandCode): Send a message to frame window (any of cmdXXX works too)
bool DisableAccelTable(): Disable standard accelerator table for window so we can use ALT, ALT+F4 etc
void Flush(PRECTL rect): Flush OpenGL buffer
glWindow(long Width, long Height, long ContextFlags): Constructor: attach OpenGL context to client of given frame handle
inline bool isMinimized(): Return minimized status
inline bool isPaused(): Return if window is paused
inline void MouseCursor(ULONG ID): Set mouse cursor shape when it is over GL window
void MouseVisible(bool State): Set mouse cursor visibility when it is over GL window
inline void Pause(bool State): Pause window: application should check IsPaused() itself
void Select(): Select this OpenGL context for drawing
inline void SetFocusHandler(tFocusHandler Handler, void *param): Define window focus change handler
inline void SetKeyboardHandler(tKeyboardHandler Handler, void *param): Define Keyboard Handler
inline void SetMouseHandler(tMouseHandler Handler, void *param): Define mouse handler
void SetPalette(u_long *palette, int count): Set OpenGL palette for color index modes
bool SetPos(long X, long Y): Set OpenGL window position
inline void SetTerminateHandler(tTerminateHandler Handler, void *param): Define Terminate Handler
inline bool SetTitle(char *Title): Set window title: This function requires a message queue
bool Show(bool Visible): Show the window
bool Unbind(bool Destroy): Unbind from window; optionally destroy window
inline void WaitFlush(): Wait until flush is complete. Recommended before calling Flush()
virtual ~glWindow(): Destructor: free all OpenGL buffers and memory

Documentation

OpenGL window class This class implements everything needed to create and use a OpenGL context under OS/2. If you attach it to a frame window (by passing a handle of a frame window in constructor) it will replace system menu (or application menu if there is one) by a specialized one. If you pass a handle of a different-type window, OpenGL context will simply attach to that window (@@ NOT TESTED! but should work). Window resises, moves etc are disabled because OS/2 OpenGL does not support resizeable output as DIVE does (why???). You can set up some additional callbacks to process all input to the window such as mouse and keyboard.
