GestureRotate

gtk.gesture_rotate.GestureRotate is a gtk.gesture.Gesture for 2-finger rotations.

Whenever the angle between both handled sequences changes, the signal@Gtk.GestureRotate::angle-changed signal is emitted.

class GestureRotate : Gesture {

this();

double getAngleDelta();

ulong connectAngleChanged(T callback, Flag!"After" after);

}

Constructors

this this(): Returns a newly created gtk.gesture.Gesture that recognizes 2-touch rotation gestures.

Functions

connectAngleChanged ulong connectAngleChanged(T callback, Flag!"After" after): Connect to AngleChanged signal.
getAngleDelta double getAngleDelta(): Gets the angle delta in radians.

From Gesture

getBoundingBox bool getBoundingBox(gdk.rectangle.Rectangle rect): If there are touch sequences being currently handled by gesture, returns true and fills in rect with the bounding box containing all active touches.
getBoundingBoxCenter bool getBoundingBoxCenter(double x, double y): If there are touch sequences being currently handled by gesture, returns true and fills in x and y with the center of the bounding box containing all active touches.
getDevice gdk.device.Device getDevice(): Returns the logical gdk.device.Device that is currently operating on gesture.
getGroup gtk.gesture.Gesture[] getGroup(): Returns all gestures in the group of gesture
getLastEvent gdk.event.Event getLastEvent(gdk.event_sequence.EventSequence sequence): Returns the last event that was processed for sequence.
getLastUpdatedSequence gdk.event_sequence.EventSequence getLastUpdatedSequence(): Returns the gdk.event_sequence.EventSequence that was last updated on gesture.
getPoint bool getPoint(gdk.event_sequence.EventSequence sequence, double x, double y): If sequence is currently being interpreted by gesture, returns true and fills in x and y with the last coordinates stored for that event sequence.
getSequenceState gtk.types.EventSequenceState getSequenceState(gdk.event_sequence.EventSequence sequence): Returns the sequence state, as seen by gesture.
getSequences gdk.event_sequence.EventSequence[] getSequences(): Returns the list of GdkEventSequences currently being interpreted by gesture.
group void group(gtk.gesture.Gesture gesture): Adds gesture to the same group than group_gesture.
handlesSequence bool handlesSequence(gdk.event_sequence.EventSequence sequence): Returns true if gesture is currently handling events corresponding to sequence.
isActive bool isActive(): Returns true if the gesture is currently active.
isGroupedWith bool isGroupedWith(gtk.gesture.Gesture other): Returns true if both gestures pertain to the same group.
isRecognized bool isRecognized(): Returns true if the gesture is currently recognized.
setSequenceState bool setSequenceState(gdk.event_sequence.EventSequence sequence, gtk.types.EventSequenceState state): Sets the state of sequence in gesture.
setState bool setState(gtk.types.EventSequenceState state): Sets the state of all sequences that gesture is currently interacting with.
ungroup void ungroup(): Separates gesture into an isolated group.
connectBegin ulong connectBegin(T callback, Flag!"After" after): Connect to Begin signal.
connectCancel ulong connectCancel(T callback, Flag!"After" after): Connect to Cancel signal.
connectEnd ulong connectEnd(T callback, Flag!"After" after): Connect to End signal.
connectSequenceStateChanged ulong connectSequenceStateChanged(T callback, Flag!"After" after): Connect to SequenceStateChanged signal.
connectUpdate ulong connectUpdate(T callback, Flag!"After" after): Connect to Update signal.
