GestureSingle

class GestureSingle(**properties: Any)

Superclasses: Gesture, EventController, Object

Subclasses: DragSource, GestureClick, GestureDrag, GestureLongPress, GestureStylus, GestureSwipe

GtkGestureSingle is a GtkGestures subclass optimized for singe-touch and mouse gestures.

Under interaction, these gestures stick to the first interacting sequence, which is accessible through get_current_sequence while the gesture is being interacted with.

By default gestures react to both %GDK_BUTTON_PRIMARY and touch events. set_touch_only can be used to change the touch behavior. Callers may also specify a different mouse button number to interact with through set_button, or react to any mouse button by setting it to 0. While the gesture is active, the button being currently pressed can be known through get_current_button.

Methods

class GestureSingle

get_button() → int

Returns the button number gesture listens for.

If this is 0, the gesture reacts to any button press.

get_current_button() → int

Returns the button number currently interacting with gesture, or 0 if there is none.

get_current_sequence() → EventSequence | None

Returns the event sequence currently interacting with gesture.

This is only meaningful if is_active returns True.

get_exclusive() → bool

Gets whether a gesture is exclusive.

For more information, see set_exclusive.

get_touch_only() → bool

Returns True if the gesture is only triggered by touch events.

set_button(button: int) → None

Sets the button number gesture listens to.

If non-0, every button press from a different button number will be ignored. Touch events implicitly match with button 1.

Parameters:

button – button number to listen to, or 0 for any button

set_exclusive(exclusive: bool) → None

Sets whether gesture is exclusive.

An exclusive gesture will only handle pointer and “pointer emulated” touch events, so at any given time, there is only one sequence able to interact with those.

Parameters:

exclusive – True to make gesture exclusive

set_touch_only(touch_only: bool) → None

Sets whether to handle only touch events.

If touch_only is True, gesture will only handle events of type %GDK_TOUCH_BEGIN, %GDK_TOUCH_UPDATE or %GDK_TOUCH_END. If False, mouse events will be handled too.

Parameters:

touch_only – whether gesture handles only touch events
