methods.
Implementors

, GestureMultiPress
, GestureSingle
, GestureStylus
, GestureSwipe
Required Methods
Returns the button number self
listens for, or 0 if self
reacts to any button press.
Returns
The button number, or 0 for any button
Returns the button number currently interacting with self
, or 0 if there
is none.
Returns
The current button number
fn current_sequence(&self) -> Option<EventSequence>
fn current_sequence(&self) -> Option<EventSequence>
Returns the event sequence currently interacting with self
.
This is only meaningful if GestureExt::is_active()
returns true
.
Returns
the current sequence
fn is_exclusive(&self) -> bool
fn is_exclusive(&self) -> bool
Gets whether a gesture is exclusive. For more information, see
set_exclusive()
.
Returns
Whether the gesture is exclusive
fn is_touch_only(&self) -> bool
fn is_touch_only(&self) -> bool
Sets the button number self
listens to. If non-0, every
button press from a different button number will be ignored.
Touch events implicitly match with button 1.
button
button number to listen to, or 0 for any button
fn set_exclusive(&self, exclusive: bool)
fn set_exclusive(&self, exclusive: bool)
fn set_touch_only(&self, touch_only: bool)
fn set_touch_only(&self, touch_only: bool)
If touch_only
is true
, self
will only handle events of type
GDK_TOUCH_BEGIN
, GDK_TOUCH_UPDATE
or GDK_TOUCH_END
. If false
,
mouse events will be handled too.
touch_only
whether self
handles only touch events
