class: DropControllerMotionEnterCallback

[219:7] extends: object

Generated low-level callback wrapper for GIR callback enter.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• DropControllerMotionEnterCallback (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, x, 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: DropControllerMotionLeaveCallback

[289:7] extends: object

Generated low-level callback wrapper for GIR callback leave.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• DropControllerMotionLeaveCallback (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, 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: DropControllerMotionMeta

[429:14] static extends: object

Generated metadata helpers for DropControllerMotion class surfaces.

Methods

• properties ()

  Returns property metadata for DropControllerMotion.

  • @r A list.

• signals ()

  Returns signal metadata for DropControllerMotion.

  • @r A list.

class: DropControllerMotion

[15:7] extends: object

An event controller tracking the pointer during Drag-and-Drop operations. It is modeled after [class@Gtk.EventControllerMotion] so if you have used that, this should feel really familiar. This controller is not able to accept drops, use [class@Gtk.DropTarget] for that purpose.

Members

• handleObj
• lib
• retainedCallbacks
• signalHandlerNames
• signalSetterHandlers

Methods

• DropControllerMotion ()

  Creates a new event controller that will handle pointer motion events during drag and drop.

• 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.

• asEventController ()

  Wraps this handle as EventController.

  • @r A EventController 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.

• setOnEnter (callback Fn, UserData = null)

  Signals that the pointer has entered the widget.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (DropControllerMotion Self, double X, double Y).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.
  • @r The connected handler id.

• setOnLeave (callback Fn, UserData = null)

  Signals that the pointer has left the widget.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (DropControllerMotion Self).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.
  • @r The connected handler id.

• setOnMotion (callback Fn, UserData = null)

  Emitted when the pointer moves inside the widget.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (DropControllerMotion Self, double X, double Y).
  • @p UserData is retained and passed through to the generated callback wrapper when provided.
  • @r The connected handler id.

• contains_pointer ()

  Returns if a Drag-and-Drop operation is within the widget @self or one of its children.

• get_drop ()

  Returns the GdkDrop of a current Drag-and-Drop operation over the widget of @self.

• is_pointer ()

  Returns if a Drag-and-Drop operation is within the widget @self, not one of its children.
