Methods

GtkGestureStylus (Handle = null)

Creates a new GtkGestureStylus.
- @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.
setOnDown (callback Fn, UserData = null)

Emitted when the stylus touches the device.
- @p Fn is the Aussom callback.
- @p Fn is called with (GtkGestureStylus 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 (GtkGestureStylus 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 (GtkGestureStylus 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 (GtkGestureStylus 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_axes (list axes)

Returns the current values for the requested @axes. 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.
- @p axes is array of requested axes, terminated with %GDK_AXIS_IGNORE.
- @p values is return location for the axis values.
- @r %TRUE if there is a current value for the axes.
get_axis (string axis)

Returns the current value for the requested @axis. 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.
- @p axis is requested device axis.
- @p value is return location for the axis value.
- @r %TRUE if there is a current value for the axis.
get_backlog ()

Returns the accumulated backlog of tracking information. By default, GTK will limit rate of input events. On stylus input where accuracy of strokes is paramount, this function returns the accumulated coordinate/timing state before the emission of the current [Gtk.GestureStylus::motion] signal. This function may only be called within a [signal@Gtk.GestureStylus::motion] signal handler, the state given in this signal and obtainable through [method@Gtk.GestureStylus.get_axis] express the latest (most up-to-date) state in motion history. The @backlog is provided in chronological order.
- @p backlog is coordinates and times for the backlog events.
- @p n_elems is return location for the number of elements.
- @r %TRUE if there is a backlog to unfold in the current state..
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.
- @r The current stylus tool.
get_stylus_only ()

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