Graphics, Windowing, and Events Subsystem (Compact 7)
3/12/2014
The Graphics, Windowing, and Events Subsystem (GWES) loads user interface device drivers that are used exclusively by GWES:
- Display drivers
- Keyboard drivers
- Mouse drivers
- Touch screen drivers
- Printer drivers
These device drivers are native drivers, and each class of device shown in the preceding list has its own interface with GWES. GWES loads each driver based on a registry key for that device driver class. To learn more about configuring the registry for loading a device driver of a specific class, see the Windows Embedded Compact 7 topics described in the following table.
| Driver type | Reference topic |
|---|---|
Display |
|
Keyboard |
|
Mouse |
|
Touch Screen |
|
Printer |
For example, GWES loads the display driver DLL specified in the registry key HKEY_LOCAL_MACHINE\System\GDI\Drivers\Display. To load a display driver, you configure the file name of the device driver in the Dll setting of this registry key, as described in Display Driver Registry Settings.
