class: GestureDragDragbeginCallback

[192:7] extends: object

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

Members

  • callbackObj
  • userFn
  • userData
  • hasUserData

Methods

  • GestureDragDragbeginCallback (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: GestureDragMeta

[402:14] static extends: object

Generated metadata helpers for GestureDrag class surfaces.

Methods

  • signals ()

    Returns signal metadata for GestureDrag.

    • @r A list.

class: GestureDragDragupdateCallback

[332:7] extends: object

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

Members

  • callbackObj
  • userFn
  • userData
  • hasUserData

Methods

  • GestureDragDragupdateCallback (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: GestureDrag

[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].

Members

  • handleObj
  • lib
  • retainedCallbacks
  • signalHandlerNames
  • signalSetterHandlers

Methods

  • GestureDrag ()

    Returns a newly created GtkGesture that recognizes drags.

  • 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 GestureSingle.

    • @r A GestureSingle 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 (GestureDrag 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 (GestureDrag 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 (GestureDrag 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.
