public sealed class GestureDrag : GestureSingle

GestureDrag is a Gesture implementation that recognizes drag operations.

The drag operation itself can be tracked throught the drag_begin, drag_update and drag_end signals, or the relevant coordinates be extracted through get_offset and get_start_point.

Namespace: Gtk

Package: gtk+-3.0

public GestureDrag (Widget widget)
Returns a newly created Gesture that recognizes drags.

public bool get_offset (out double x, out double y)
If the this is active, this function returns true and fills in x and y with the coordinates of the current point, as an offset to the starting drag point.
public bool get_start_point (out double x, out double y)
If the this is active, this function returns true and fills in x and y with the drag start coordinates, in window-relative coordinates.

public signal void drag_begin (double start_x, double start_y)
This signal is emitted whenever dragging starts.
public signal void drag_end (double offset_x, double offset_y)
This signal is emitted whenever the dragging is finished.
public signal void drag_update (double offset_x, double offset_y)
This signal is emitted whenever the dragging point moves.
