The QWaylandSeat class provides access to keyboard, mouse, and touch input.
The QWaylandSeat 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.
This enum type describes the capabilities of a QWaylandSeat .
| 常量 | 值 | 描述 |
|---|---|---|
QWaylandSeat::Pointer
|
0x01
|
The QWaylandSeat supports pointer input. |
QWaylandSeat::Keyboard
|
0x02
|
The QWaylandSeat supports keyboard input. |
QWaylandSeat::Touch
|
0x04
|
The QWaylandSeat supports touch input. |
QWaylandSeat::DefaultCapabilities
|
Pointer | Keyboard | Touch
|
The QWaylandSeat has the default capabilities. |
The CapabilityFlags type is a typedef for QFlags <CapabilityFlag>. It stores an OR combination of CapabilityFlag values.
