/**
|
|
|
|
* @brief Represents a Seat on the Wayland Display.
|
|
|
|
*
|
|
|
|
* A Seat is a set of input devices (e.g. Keyboard, Pointer and Touch) the client can connect
|
|
|
|
* to. The server needs to announce which input devices are supported and passes dedicated input
|
|
|
|
* focus to a SurfaceInterface. Only the focused surface receives input events.
|
|
|
|
*
|
|
|
|
* The SeatInterface internally handles enter and release events when setting a focused surface.
|
|
|
|
* Also it handles input translation from global to the local coordination, removing the need from
|
|
|
|
* the user of the API to track the focused surfaces and can just interact with this class.
|
|
|
|
*
|
|
|
|
* To create a SeatInterface use @link Display::createSeat @endlink. Then one can set up what is
|
|
|
|
* supported. Last but not least create needs to be called.
|
|
|
|
*
|
|
|
|
* @code
|
|
|
|
* SeatInterface *seat = display->createSeat();
|
|
|
|
* // set up
|
|
|
|
* seat->setName(QStringLiteral("seat0"));
|
|
|
|
* seat->setHasPointer(true);
|
|
|
|
* seat->setHasKeyboard(true);
|
|
|
|
* seat->setHasTouch(false);
|
|
|
|
* // now fully create
|
|
|
|
* seat->create();
|
|
|
|
* @endcode
|
|
|
|
*
|
|
|
|
* To forward input events one needs to set the focused surface, update time stamp and then
|
|
|
|
* forward the actual events:
|
|
|
|
*
|
|
|
|
* @code
|
|
|
|
* // example for pointer
|
|
|
|
* seat->setFocusedPointerSurface(surface, QPointF(100, 200)); // surface at it's global position
|
|
|
|
* seat->setTimestamp(100);
|
|
|
|
* seat->setPointerPos(QPointF(350, 210)); // global pos, local pos in surface: 250,10
|
|
|
|
* seat->setTimestamp(110);
|
|
|
|
* seat->pointerButtonPressed(Qt::LeftButton);
|
|
|
|
* seat->setTimestamp(120);
|
|
|
|
* seat->pointerButtonReleased(Qt::LeftButton);
|
|
|
|
* @endcode
