Struct gtk4::GestureSwipe
source · #[repr(transparent)]pub struct GestureSwipe { /* private fields */ }Expand description
GestureSwipe is a Gesture for swipe gestures.
After a press/move/…/move/release sequence happens, the
signal::GestureSwipe::swipe signal will be emitted,
providing the velocity and directionality of the sequence
at the time it was lifted.
If the velocity is desired in intermediate points,
velocity() can be called in a
signal::Gesture::update handler.
All velocities are reported in pixels/sec units.

Implementations§
source§impl GestureSwipe
impl GestureSwipe
sourcepub fn new() -> GestureSwipe
pub fn new() -> GestureSwipe
sourcepub fn builder() -> GestureSwipeBuilder
pub fn builder() -> GestureSwipeBuilder
Creates a new builder-pattern struct instance to construct GestureSwipe objects.
This method returns an instance of GestureSwipeBuilder which can be used to create GestureSwipe objects.
sourcepub fn velocity(&self) -> Option<(f64, f64)>
pub fn velocity(&self) -> Option<(f64, f64)>
Gets the current velocity.
If the gesture is recognized, this function returns true and fills
in @velocity_x and @velocity_y with the recorded velocity, as per the
last events processed.
Returns
whether velocity could be calculated
velocity_x
return value for the velocity in the X axis, in pixels/sec
velocity_y
return value for the velocity in the Y axis, in pixels/sec
sourcepub fn connect_swipe<F: Fn(&Self, f64, f64) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_swipe<F: Fn(&Self, f64, f64) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the recognized gesture is finished.
Velocity and direction are a product of previously recorded events.
velocity_x
velocity in the X axis, in pixels/sec
velocity_y
velocity in the Y axis, in pixels/sec
