pub struct Touch {
// some fields omitted
}Methods
impl Touch
fn get_id(&self) -> TouchId
Returns the unique \TouchId` associated with this touch device.
This struct can be tested for equality, and will be provided in event callbacks as a mean to identify the toch device associated with the events.
fn get_seat(&self) -> &Seat
Get access to the seat associated with this keyboard
fn release(self)
fn set_down_action<F>(&mut self, f: F) where F: Fn(TouchId, Serial, u32, SurfaceId, i32, f64, f64) + 'static + Send + Sync
Defines the action to be executed when a new touch point appears
Arguments are:
- Id of the touch
- serial number of the event
- timestamp with miliseconds of the event
- id of the surface of the event
- unique id for this touch point (will be used to identify it when moving or when disappearing)
- x coordinate of the touch point on the surface
- y coordinate of the touch point on the surface
fn set_up_action<F>(&mut self, f: F) where F: Fn(TouchId, Serial, u32, i32) + 'static + Send + Sync
Defines the action to be executed when a touch point dissapears
Arguments are:
- Id of the touch
- serial number of the event
- timestamp with miliseconds of the event
- unique id for this touch point (this id is then released and can be used for new touch points)
fn set_motion_action<F>(&mut self, f: F) where F: Fn(TouchId, u32, i32, f64, f64) + 'static + Send + Sync
Defines the action to be executed a touch point moves
Arguments are:
- Id of the touch
- timestamp with miliseconds of the event
- unique id for this touch point
- new x coordinate of the touch point on the surface
- new y coordinate of the touch point on the surface
fn set_frame_action<F>(&mut self, f: F) where F: Fn(TouchId) + 'static + Send + Sync
fn set_cancel_action<F>(&mut self, f: F) where F: Fn(TouchId) + 'static + Send + Sync
Defines the action to be executed when a touch sequence is cancelled.
This happens when the compositer recognises the sequence as a special sequence that it will interpret itself.
All current touch points are cancelled and their ids released (and thus can be used for new touch points).
