GestureDrag

GtkGestureDrag is a GtkGesture 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 [method@Gtk.GestureDrag.get_offset] and [method@Gtk.GestureDrag.get_start_point].

class GestureDrag : GestureSingle {

GtkGestureDrag* gtkGestureDrag;

GtkGestureDrag* getGestureDragStruct(bool transferOwnership);

void* getStruct();

this(GtkGestureDrag* gtkGestureDrag, bool ownedRef);

static GType getType();

this();

bool getOffset(double x, double y);

bool getStartPoint(double x, double y);

gulong addOnDragBegin(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags);

gulong addOnDragEnd(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags);

gulong addOnDragUpdate(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags);

}

Constructors

this this(GtkGestureDrag* gtkGestureDrag, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Returns a newly created GtkGesture that recognizes drags.
