Programming Notes
|
|
=================
|
|
For details on how to setup a windowed mode DirectDraw app, see the WindowedMode
|
|
sample.
|
|
|
|
To use overlays in general do the following steps in addition to those needed to
|
|
author a windowed mode DirectDraw app:
|
|
1. Check to see if hardware supports overlays - check IDirectDraw::GetCaps
|
|
for DDCAPS_OVERLAY.
|
|
2. Size the window to meet the hardware overlay size restrictions.
|
|
3. Create an overlay surface (create it with 1 backbuffer if needed), and
|
|
set its pixel format to a desired format that is supported by the device.
|
|
4. Set the dest color key on the overlay to the background color of the window.
|
|
Be sure to choose a color for the background of the window that Windows typically
|
|
does not use otherwise, the overlay will be drawn on top of overlapping windows.
|
|
5. Call UpdateOverlay to display or hide the overlay on the desktop. WM_PAINT is
|
|
a good place for this.
|
|
6. When WM_SIZE or WM_MOVE is sent, then update the src and dest rects and
|
|
check to make sure that they are within the hardware limits.
|
|
|
|
To animate the overlay, instead of drawing to the off-screen plain back buffer as
|
|
in windowed mode case, just draw to the the overlay's backbuffer then flip it.
