Generated low-level callback wrapper for GIR callback drag-begin.

Members

Methods

GtkGestureDragDragbeginCallback (callback Fn, UserData = null)

Creates one native callback wrapper. The wrapper owns a trampoline that converts native pointers into generated wrapper objects before invoking Fn.
- @p Fn is the Aussom callback implementation.
- @p UserData is retained and passed through to Fn on each invocation when provided.
trampoline (nativeSelf, start_x, start_y, nativeUserData)

Internal trampoline. Converts native pointer arguments into generated wrapper instances, then invokes the user's callback.
callback ()

Returns the wrapped NativeCallback.
handle ()

Returns the callback as a NativeHandle.
close ()

Closes the underlying NativeCallback.
isClosed ()

Returns true when the callback has been closed.

class: GtkGestureDragDragendCallback

[299:7] extends: object

Generated low-level callback wrapper for GIR callback drag-end.

Methods

GtkGestureDragDragendCallback (callback Fn, UserData = null)

Creates one native callback wrapper. The wrapper owns a trampoline that converts native pointers into generated wrapper objects before invoking Fn.
- @p Fn is the Aussom callback implementation.
- @p UserData is retained and passed through to Fn on each invocation when provided.
trampoline (nativeSelf, offset_x, offset_y, nativeUserData)

Internal trampoline. Converts native pointer arguments into generated wrapper instances, then invokes the user's callback.
callback ()

Returns the wrapped NativeCallback.
handle ()

Returns the callback as a NativeHandle.
close ()

Closes the underlying NativeCallback.
isClosed ()

Returns true when the callback has been closed.

class: GtkGestureDragMeta

[439:14] static extends: object

Generated metadata helpers for GestureDrag class surfaces.

Methods

signals ()

Returns signal metadata for GestureDrag.
- @r A list.

class: GtkGestureDragDragupdateCallback

[369:7] extends: object

Generated low-level callback wrapper for GIR callback drag-update.

Methods

GtkGestureDragDragupdateCallback (callback Fn, UserData = null)

Creates one native callback wrapper. The wrapper owns a trampoline that converts native pointers into generated wrapper objects before invoking Fn.
- @p Fn is the Aussom callback implementation.
- @p UserData is retained and passed through to Fn on each invocation when provided.
trampoline (nativeSelf, offset_x, offset_y, nativeUserData)

callback ()

Returns the wrapped NativeCallback.
handle ()

Returns the callback as a NativeHandle.
close ()

Closes the underlying NativeCallback.
isClosed ()

Returns true when the callback has been closed.

class: GtkGestureDrag

[17:7] extends: object

Recognizes drag gestures. 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].

Methods

GtkGestureDrag (Handle = null)

Returns a newly created GtkGesture that recognizes drags.
- @p Handle is an optional native handle or wrapper whose handle to adopt; when the native constructor is called.
toNativeHandle (Source)

Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.
- @p Source is the raw handle, raw buffer, wrapper, or null.
- @r A raw pointer carrier or null when no pointer is present.
getLib ()

Returns the opened native library for this generated wrapper.
- @r The opened native library.
handle ()

Returns the wrapped NativeHandle.
- @r The wrapped NativeHandle.
isNull ()

Returns true when the wrapped handle is null.
- @r A bool.
describe ()

Returns a small string for debugging generated wrappers.
- @r A string.
asGestureSingle ()

Wraps this handle as GtkGestureSingle.
- @r A GtkGestureSingle object.
connectSignal (string Name, CallbackObj)

Connects one generated callback wrapper to a named signal.
- @p Name is the signal name.
- @p CallbackObj is the generated callback wrapper to connect.
- @r The connected handler id.
disconnectSignalHandler (int HandlerId)

Disconnects one retained signal handler id.
- @p HandlerId is the signal handler id to disconnect.
- @r None.
setOnDragbegin (callback Fn, UserData = null)

Emitted whenever dragging starts.
- @p Fn is the Aussom callback.
- @p Fn is called with (GtkGestureDrag Self, double Start_x, double Start_y).
- @p UserData is retained and passed through to the generated callback wrapper when provided.
- @r The connected handler id.
setOnDragend (callback Fn, UserData = null)

Emitted whenever the dragging is finished.
- @p Fn is the Aussom callback.
- @p Fn is called with (GtkGestureDrag Self, double Offset_x, double Offset_y).
- @p UserData is retained and passed through to the generated callback wrapper when provided.
- @r The connected handler id.
setOnDragupdate (callback Fn, UserData = null)

Emitted whenever the dragging point moves.
- @p Fn is the Aussom callback.
- @p Fn is called with (GtkGestureDrag Self, double Offset_x, double Offset_y).
- @p UserData is retained and passed through to the generated callback wrapper when provided.
- @r The connected handler id.
get_offset ()

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.
- @p x is X offset for the current point.
- @p y is Y offset for the current point.
- @r %TRUE if the gesture is active.
get_start_point ()

Gets the point where the drag started. If the @gesture is active, this function returns %TRUE and fills in @x and @y with the drag start coordinates, in widget-relative coordinates.
- @p x is X coordinate for the drag start point.
- @p y is Y coordinate for the drag start point.
- @r %TRUE if the gesture is active.
