Detailed Description
A key press event handler that detects long key presses and report them as specified.
This class offers two specific reactions for long key presses. Either a specific long key press is reported or the key press event is auto repeated. The timing for both kind of reactions can be specified independently. The monitor reacts on key code, not on mapped key char. If a mapped key char is present in the event, it is retained in the generated key press events.

Member Function Documentation
| void attach | ( | FunctionKeyPressEventHandler::HandlerFunction | fn ) | [inherited] |
Attaches the monitor to a function.
- Parameters:
-
fn Event handler called to report keyboard state change.
Definition at line 18 of file KeyPressEventServer.h.
| void attach | ( | T * | obj, |
| typename MemberKeyPressEventHandler< T >::MemberFunction | fn | ||
| ) | [inherited] |
Attaches the monitor to a method of an object.
- Parameters:
-
obj Event handler object fn Event handler method called to report keyboard state after each complete scan.

| LongKeyPressMonitor::AutoRepeatSetupProxy autoRepeat | ( | float | initTime, |
| float | delay | ||
| ) |
Sets up auto-repeat keys.
This method takes the timing parameters. It returns a special class that allows specifying the keys between brackets. Eg:
- monitor.autoRepeat(0.3, 0.1)(1)(2)(4,8) Sets up auto repeat after 300ms, every 100ms for keys 1, 2 and 4 to 8.

| void handleKeyPress | ( | const KeyEvent & | keypress ) | [virtual] |
KeyPressEventHandler interface.
Implements KeyPressEventHandler.
Definition at line 35 of file LongKeyPressMonitor.cpp.
| LongKeyPressMonitor::LongPressSetupProxy longKeyPress | ( | float | longPressTime ) |
Sets up long key press keys.
This method takes the timing parameters. It returns a special class that allows specifying the keys between brackets. Eg:
- monitor.longKeyPress(0.5)(3)(12,14) Sets up report of long key press after 500ms for keys 3 and 12 to 14.
