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