Struct gtk4::GestureClick [−][src]
pub struct GestureClick(_);Expand description
GestureClick is a Gesture implementation for clicks.
It is able to recognize multiple clicks on a nearby zone, which
can be listened for through the signal::GestureClick::pressed
signal. Whenever time or distance between clicks exceed the GTK
defaults, signal::GestureClick::stopped is emitted, and the
click counter is reset.
Implements
GestureSingleExt, GestureExt, EventControllerExt, glib::ObjectExt
Implementations
Returns a newly created Gesture that recognizes
single and multiple presses.
Returns
a newly created GestureClick
Creates a new builder-pattern struct instance to construct GestureClick objects.
This method returns an instance of GestureClickBuilder which can be used to create GestureClick objects.
pub fn connect_released<F: Fn(&Self, i32, f64, f64) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_released<F: Fn(&Self, i32, f64, f64) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when a button or touch is released.
n_press will report the number of press that is paired to
this event, note that signal::GestureClick::stopped may
have been emitted between the press and its release, n_press
will only start over at the next press.
n_press
number of press that is paired with this release
x
The X coordinate, in widget allocation coordinates
y
The Y coordinate, in widget allocation coordinates
Emitted whenever any time/distance threshold has been exceeded.
pub fn connect_unpaired_release<F: Fn(&Self, f64, f64, u32, &EventSequence) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_unpaired_release<F: Fn(&Self, f64, f64, u32, &EventSequence) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted whenever the gesture receives a release event that had no previous corresponding press.
Due to implicit grabs, this can only happen on situations where input is grabbed elsewhere mid-press or the pressed widget voluntarily relinquishes its implicit grab.
x
X coordinate of the event
y
Y coordinate of the event
button
Button being released
sequence
Sequence being released

Tries to cast to an object of type T. This handles upcasting, downcasting
