class: GestureStylusMotionCallback

[341:7] extends: object

Generated low-level callback wrapper for GIR callback motion.

Members

• callbackObj
• userFn
• userData
• hasUserData

Methods

• GestureStylusMotionCallback (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: GestureStylus

Methods

• GestureStylus ()

  Creates a new GtkGestureStylus.

• 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.

• setOnDown (callback Fn, UserData = null)

  Emitted when the stylus touches the device.

  • @p Fn is the Aussom callback.
  • @p Fn is called with (GestureStylus Self, double X, double Y).
  • @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 stylus moves while touching the device.

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

• setOnProximity (callback Fn, UserData = null)

  Emitted when the stylus is in proximity of the device.

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

• setOnUp (callback Fn, UserData = null)

  Emitted when the stylus no longer touches the device.

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

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setStylusonly (bool Value)

  If this gesture should exclusively react to stylus input devices.

  • @p Value is the new property value.
  • @r None.

• get_device_tool ()

  Returns the GdkDeviceTool currently driving input through this gesture. This function must be called from the handler of one of the [signal@Gtk.GestureStylus::down], [signal@Gtk.GestureStylus::motion], [signal@Gtk.GestureStylus::up] or [signal@Gtk.GestureStylus::proximity] signals.

• get_stylus_only ()

  Checks whether the gesture is for styluses only. Stylus-only gestures will signal events exclusively from stylus input devices.

• set_stylus_only (bool stylus_only)

  Sets the state of stylus-only If true, the gesture will exclusively handle events from stylus input devices, otherwise it'll handle events from any pointing device.

  • @p stylus_only is whether the gesture is used exclusively for stylus events.
  • @r None.
