Detailed Description

The KeyboardFilter class provides a global keyboard event filter.

Note that this class is only available in Qtopia Core.

KeyboardFilter is used to implement a global, low-level filter on key events in the Qtopia Core server application; this can be used to implement things like APM (advanced power management) suspended from a button without having to filter for it in all applications.

See also QWSServer, QWSInputMethod, and Character Input.

KeyboardFilter::~KeyboardFilter () `[virtual]`

Destroys the keyboard filter.

bool KeyboardFilter::filter ( int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat ) `[pure virtual]`
