GestureDrag

gtk.GestureDrag is a gtk.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 Gesture.dragGetOffset and Gesture.dragGetStartPoint.

class GestureDrag : GestureSingle {

protected

GtkGestureDrag* gtkGestureDrag;

GtkGestureDrag* getGestureDragStruct(bool transferOwnership);

void* getStruct();

this(GtkGestureDrag* gtkGestureDrag, bool ownedRef);

static GType getType();

this(Widget widget);

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(Widget widget): Returns a newly created gtk.Gesture that recognizes drags.

Functions

addOnDragBegin gulong addOnDragBegin(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags): This signal is emitted whenever dragging starts.
addOnDragEnd gulong addOnDragEnd(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags): This signal is emitted whenever the dragging is finished.
addOnDragUpdate gulong addOnDragUpdate(void delegate(double, double, GestureDrag) dlg, ConnectFlags connectFlags): This signal is emitted whenever the dragging point moves.
getGestureDragStruct GtkGestureDrag* getGestureDragStruct(bool transferOwnership): Get the main Gtk struct
getOffset bool getOffset(double x, double y): 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.
getStartPoint bool getStartPoint(double x, double y): If the gesture is active, this function returns TRUE and fills in x and y with the drag start coordinates, in window-relative coordinates.
getStruct void* getStruct(): the main Gtk struct as a void*

Variables

gtkGestureDrag GtkGestureDrag* gtkGestureDrag;: the main Gtk struct

From GestureSingle

gtkGestureSingle GtkGestureSingle* gtkGestureSingle;: the main Gtk struct
getGestureSingleStruct GtkGestureSingle* getGestureSingleStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getType GType getType()
getButton uint getButton(): Returns the button number gesture listens for, or 0 if gesture reacts to any button press.
getCurrentButton uint getCurrentButton(): Returns the button number currently interacting with gesture, or 0 if there is none.
getCurrentSequence GdkEventSequence* getCurrentSequence(): Returns the event sequence currently interacting with gesture. This is only meaningful if Gesture.isActive returns TRUE.
getExclusive bool getExclusive(): Gets whether a gesture is exclusive. For more information, see Gesture.singleSetExclusive.
getTouchOnly bool getTouchOnly(): Returns TRUE if the gesture is only triggered by touch events.
setButton void setButton(uint button): Sets the button number gesture listens to. If non-0, every button press from a different button number will be ignored. Touch events implicitly match with button 1.
setExclusive void setExclusive(bool exclusive): Sets whether gesture is exclusive. An exclusive gesture will only handle pointer and "pointer emulated" touch events, so at any given time, there is only one sequence able to interact with those.
setTouchOnly void setTouchOnly(bool touchOnly): If touch_only is TRUE, gesture will only handle events of type GDK_TOUCH_BEGIN, GDK_TOUCH_UPDATE or GDK_TOUCH_END If FALSE, mouse events will be handled too.
