ICDrawWindow macro (vfw.h)
The ICDrawWindow macro notifies a rendering driver that the window specified for the ICM_DRAW_BEGIN message needs to be redrawn. The window has moved or become temporarily obscured. You can use this macro or explicitly call the ICM_DRAW_WINDOW message.
Syntax
void ICDrawWindow(
hic,
prc
);
Parameters
hic
Handle to a driver.
prc
Pointer to the destination rectangle in screen coordinates. If this parameter points to an empty rectangle, drawing should be turned off.
Return value
None
Remarks
This message is supported by hardware that performs its own asynchronous decompression, timing, and drawing.
Video-overlay drivers use this message to draw when the window is obscured or moved. When a window specified for ICM_DRAW_BEGIN is completely hidden by other windows, the destination rectangle is empty. Drivers should turn off video-overlay hardware when this condition occurs.
