Detailed Description
A hybrid between a DEVICE_X and DEVICE_MEM32RGB.
To the caller, this seems to be just like an MGD::DEVICE_MEM32RGB but it also creates an X Pixmap the same size. After doing some rendering, call UpdatePixmap() to transfer the contents of the memory frame buffer to the pixmap. If the X device is not 32-bit, it will automatically convert the image to the format necessary.

| ) |
Create a buffered pixmap for an X display and drawable.
- Parameters:
-
display X display pointer drawable X drawable height Height in pixels width Width in pixels
Create a buffered pixmap for an X Widget.
Size will be determined from widget. Widget background pixmap will be set to the buffered pixmap. When widget size changes, you must call UpdateSize() to adjust the pixmap size. This is not done automatically to avoid multiple updates during user sizing operation.
| Pixmap MGD::DEVICE_X32::GetPixmap | ( | ) | const [inline] |
Return the pixmap being used for this device.
Note that the pixmap is owned by the device and will be freed when the device is destroyed.
| MGD::DEVICE_X& MGD::DEVICE_X32::GetXDevice | ( | ) | [inline] |
Get the X device associated with this device.
Resize the pixmap and image buffer.
Current contents are destroyed by this process. New pixmap is blank. Previous pixmap will be destroyed in the process.
| void MGD::DEVICE_X32::UpdatePixmap | ( | ) |
Transfer the contents of the memory frame buffer to the X Pixmap.
| ERRVALUE MGD::DEVICE_X32::UpdateSize | ( | ) |
Update buffered pixmap size after widget size changes.
Current pixmap contents will be destroyed and the new contents will be blank.
