class Gtk::GestureDrag
Overview
Gtk::GestureDrag
is a Gtk::Gesture
implementation for drags.
The drag operation itself can be tracked throughout the
[signal@Gtk.GestureDrag::drag-begin],
[signal@Gtk.GestureDrag::drag-update] and
[signal@Gtk.GestureDrag::drag-end] signals, and the relevant
coordinates can be extracted through
Gtk::GestureDrag#offset
and
Gtk::GestureDrag#start_point
.

Instance Method Detail
Gets the offset from the start point.
If the @gesture 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.
