The WaylandSeat type provides access to different types of user input and maintains a keyboard focus and a mouse pointer. It corresponds to the wl_seat interface in the Wayland protocol.

void cursorSurfaceRequest ( QWaylandSurface surface , int hotspotX , int hotspotY ) |
This signal is emitted when the client has requested for a specific surface to be the mouse cursor. For example, when the user hovers over a particular surface, and you want the cursor to change into a resize arrow.
Both hotspotX and hotspotY are offsets from the top-left of a pointer surface, where a click should happen. For example, if the requested cursor surface is an arrow, the parameters indicate where the arrow's tip is, on that surface.

void keyboardFocusChanged ( QWaylandSurface newFocus , QWaylandSurface oldFocus ) |
This signal is emitted when setKeyboardFocus() is called or when a WaylandQuickItem has focus and the user starts pressing keys.
newFocus
has the surface that received keyboard focus; or
nullptr
if no surface has focus.
oldFocus
has the surface that lost keyboard focus; or
nullptr
if no surface had focus.

void sendTouchCancelEvent ( WaylandClient client ) |
Sends a cancel event to the touch device of a client .
|
void sendTouchFrameEvent ( WaylandClient client ) |
Sends a frame event to the touch device of a client to indicate the end of a series of touch up, down, and motion events.
|
void sendTouchPointMoved ( WaylandSurface surface , int id , point position ) |
Sends a touch moved event for the touch point id on surface with position position .
注意： You need to send a touch frame event when you are done sending touch events.
警告： This API should not be used in combination with forwarding of touch events using WaylandQuickItem::touchEventsEnabled , as it might lead to conflicting touch ids.
Returns the serial for the touch motion event.
|
uint sendTouchPointPressed ( WaylandSurface surface , int id , point position ) |
Sends a touch pressed event for the touch point id on surface with position position .
注意： You need to send a touch frame event when you are done sending touch events.
警告： This API should not be used in combination with forwarding of touch events using WaylandQuickItem::touchEventsEnabled , as it might lead to conflicting touch ids.
Returns the serial for the touch down event.
|
void sendTouchPointReleased ( WaylandSurface surface , int id , point position ) |
Sends a touch released event for the touch point id on surface with position position .
注意： You need to send a touch frame event when you are done sending touch events.
警告： This API should not be used in combination with forwarding of touch events using WaylandQuickItem::touchEventsEnabled , as it might lead to conflicting touch ids.
Returns the serial for the touch up event.

Sends a key press event of a UCS4 unicode through a text-input protocol.
注意： This function will not work properly if the client does not support the text-input protocol that the compositor supports.
This method was introduced in Qt 6.7.
