Constructor Detail

def self.new : self #

Creates a new Gtk::GestureStylus.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def axes(axes : Enumerable(Gdk::AxisUse), values : Enumerable(Float64)) : Bool #

Returns the current values for the requested axes.

This function must be called from the handler of one of the Gtk::GestureStylus::#down, Gtk::GestureStylus::#motion, Gtk::GestureStylus::#up or Gtk::GestureStylus::#proximity signals.


[View source]
def axis(axis : Gdk::AxisUse, value : Float64) : Bool #

Returns the current value for the requested axis.

This function must be called from the handler of one of the Gtk::GestureStylus::#down, Gtk::GestureStylus::#motion, Gtk::GestureStylus::#up or Gtk::GestureStylus::#proximity signals.


[View source]
def backlog(backlog : Enumerable(Gdk::TimeCoord)) : Bool #

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 Gtk::GestureStylus::#motion signal handler, the state given in this signal and obtainable through Gtk::GestureStylus#axis express the latest (most up-to-date) state in motion history.

The backlog is provided in chronological order.


[View source]
def backlog(*backlog : Gdk::TimeCoord) #

[View source]
def device_tool : Gdk::DeviceTool | Nil #

Returns the Gdk::DeviceTool currently driving input through this gesture.

This function must be called from the handler of one of the Gtk::GestureStylus::#down, Gtk::GestureStylus::#motion, Gtk::GestureStylus::#up or Gtk::GestureStylus::#proximity signals.
