- Description
The TDx_Draw::SetDisplayMode method will set the mode of the display hardware.
Other applications changing the display mode will cause the primary surface to be lost and result in DDERR_SURFACELOST messages until the surface is recreated to match the new display mode.
This method must be called by the thread which created the application window.
If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_GENERIC
DDERR_INVALIDMODE
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
DDERR_LOCKEDSURFACES
DDERR_NOEXCLUSIVEMODE
DDERR_SURFACEBUSY
DDERR_UNSUPPORTED
DDERR_UNSUPPORTEDMODE
DDERR_WASSTILLDRAWING
- Parameters
Width
The Width parameter defines the width of the mode being set.
Height
The Height parameter defines the height of the mode being set.
BPP
The BPP parameter defines the bit depth of the mode being set. To determine the Pixel format used by the hardware, use TDx_Draw::GetDisplayMode(), which will return the pixel masks used.
RefreshRate
The RefreshRate parameter defines the refresh rate of the mode being set.
Set this parameter to 0 to use the current refresh rate setting.
Flags
The Flags parameter defines a flag indicating an additional mode option.
The described effect applies when this flag is set.
-
DDSDM_STANDARDVGAMODE
Mode 13 will be set instead of Mode X 320x200x8 mode.
When not setting Mode 13 this parameter should be set to 0.
Refer to the DirectX SDK for details on "Mode X and Mode 13 Display Modes" limitations.
