The following table shows the Display driver methods with a description of the purpose of each.
| Programming element | Description |
|---|---|
This method executes when the driver must allocate storage for surface pixels. |
|
This method executes to complete a blit sequence initiated by GPE::BltPrepare. GPE calls this method. |
|
This method identifies the appropriate functions needed to perform individual blits. |
|
This method populates a GPEMode structure with data for the requested mode. |
|
This method executes before and after a sequence of line segments, which are drawn as a path. |
|
This method executes from applications either to move the hot spot of the cursor to a specific screen location or to hide the cursor. |
|
This method returns the number of display modes supported by a driver. A simple implementation returns 1. |
|
This method executes to enable the device driver based on the Graphics Primitive Engine (GPE) and to request a specific mode for the display. |
|
This method sets the shape of the pointer, the hot spot of the pointer, and the colors to use for the cursor if the cursor is multicolored. |
|
This method creates a system-memory surface and allocates storage. |
|
This method initializes a newly created GPESurf object. |
