#include <QWSKeyboardHandler>
The QWSKeyboardHandler class implements the keyboard driver for Qt/Embedded.
The keyboard driver handles events from system devices and generates key events.
A QWSKeyboardHandler will usually open some system device in its constructor, create a QSocketNotifier on that opened device and when it receives data, it will call processKeyEvent() to send the event to Qt/Embedded for relaying to clients.
Constructs a keyboard handler. The handler may be passed to the system for later destruction with QWSServer::setKeyboardHandler(), although even without doing this, the handler can function, calling processKeyEvent() to emit events.
Destroys a keyboard handler. Note that if you have called QWSServer::setKeyboardHandler(), you must not delete the handler.
Begin auto repeating the specified key press. After a short delay the key sequence will be sent periodically until endAutoRepeat() is called.
See also endAutoRepeat().
Stop auto-repeating a key press.
See also beginAutoRepeat().
Subclasses call this function to send a key event. The server may additionally filter the event before sending it on to applications.
Parameter | Meaning |
---|---|
unicode | The Unicode value for the key, or 0xFFFF is none is appropriate. |
keycode | The Qt keycode for the key (see Qt::Key for the list of codes). |
modifiers | The set of modifier keys (see Qt::Modifier). |
isPress | Whether this is a press or a release. |
autoRepeat | Whether this event was generated by an auto-repeat mechanism, or an actual key press. |
Transforms an arrow key (Qt::Key_Left, Qt::Key_Up, Qt::Key_Right, Qt::Key_Down) to the orientation of the display.
