class Gtk::GestureStylus
Overview
Gtk::GestureStylus
is a Gtk::Gesture
specific to stylus input.
The provided signals just relay the basic information of the stylus events.
Defined in:
lib/gi-crystal/src/auto/gtk-4.0/gesture_stylus.crConstructors

Instance Method Detail
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.
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.
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.
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.
