Struct gtk::GestureSingle
source · [−]#[repr(transparent)]pub struct GestureSingle { /* private fields */ }
Expand description
GestureSingle
is a subclass of Gesture
, optimized (although
not restricted) for dealing with mouse and single-touch gestures. Under
interaction, these gestures stick to the first interacting sequence, which
is accessible through GestureSingleExt::current_sequence()
while the
gesture is being interacted with.
By default gestures react to both GDK_BUTTON_PRIMARY
and touch
events, GestureSingleExt::set_touch_only()
can be used to change the
touch behavior. Callers may also specify a different mouse button number
to interact with through GestureSingleExt::set_button()
, or react to any
mouse button by setting 0. While the gesture is active, the button being
currently pressed can be known through GestureSingleExt::current_button()
.
