pub struct SwipeTracker { /* private fields */ }
Expand description
A swipe tracker used in Carousel
, NavigationView
and
OverlaySplitView
.
The SwipeTracker
object can be used for implementing widgets with swipe
gestures. It supports touch-based swipes, pointer dragging, and touchpad
scrolling.
The widgets will probably want to expose the enabled
property. If they expect to use horizontal orientation,
reversed
can be used for supporting RTL text
direction.
§Properties
§allow-long-swipes
Whether to allow swiping for more than one snap point at a time.
If the value is FALSE
, each swipe can only move to the adjacent snap
points.
Readable | Writeable
§allow-mouse-drag
Whether to allow dragging with mouse pointer.
Readable | Writeable
§allow-window-handle
Whether to allow touchscreen swiping from GtkWindowHandle
.
This will make dragging the window impossible.
Readable | Writeable
§enabled
Whether the swipe tracker is enabled.
When it’s not enabled, no events will be processed. Usually widgets will want to expose this via a property.
Readable | Writeable
§lower-overshoot
Whether to allow swiping past the first available snap point.
Readable | Writeable
§reversed
Whether to reverse the swipe direction.
If the swipe tracker is horizontal, it can be used for supporting RTL text direction.
Readable | Writeable
§swipeable
The widget the swipe tracker is attached to.
Readable | Writeable | Construct Only
§upper-overshoot
Whether to allow swiping past the last available snap point.
Readable | Writeable
§Signals
§begin-swipe
This signal is emitted right before a swipe will be started, after the drag threshold has been passed.
§end-swipe
This signal is emitted as soon as the gesture has stopped.
The user is expected to animate the deceleration from the current progress
value to @to with an animation using @velocity as the initial velocity,
provided in pixels per second. SpringAnimation
is usually a good
fit for this.
§prepare
This signal is emitted when a possible swipe is detected.
The @direction value can be used to restrict the swipe to a certain direction.
§update-swipe
This signal is emitted every time the progress value changes.
§Implements
[trait@glib::ObjectExt
], gtk::prelude::OrientableExt
GLib type: GObject with reference counted clone semantics.
