Event controller for drawing tablet pads.
Gtk::PadController is an event controller for the pads found in drawing tablets (The collection of buttons and tactile sensors often found around the stylus-sensitive area).
These buttons and sensors have no implicit meaning, and by default they perform no action. This event controller is provided to map those to Gio::Action objects, thus letting the application give those a more semantic meaning.
Buttons and sensors are not constrained to triggering a single action, some Gdk::InputSource::TABLET_PAD devices feature multiple "modes". All these input elements have one current mode, which may determine the final action being triggered. Pad devices often divide buttons and sensors into groups. All elements in a group share the same current mode, but different groups may have different modes. See Gdk::DevicePad::get_n_groups() and Gdk::DevicePad::get_group_n_modes().
Each of the actions that a given button/strip/ring performs for a given mode is defined by a Gtk::PadActionEntry. It contains an action name that will be looked up in the given Gio::ActionGroup and activated whenever the specified input element and mode are triggered.
A simple example of Gtk::PadController usage, assigning button 1 in all modes and pad devices to a "black" action and button 2 to a "pink" action:
};
for (const auto& entry : entries)
action_group->add_action(entry.get_action_name(),
sigc::mem_fun(*
this, &MyWindow::on_pad_activated));
pad_controller->set_action_entries(entries);
add_controller(pad_controller);
The actions belonging to rings/strips will be activated with a parameter of type Glib::Variant<double> bearing the value of the given axis. It is required that those are made stateful and accepting this Glib::VariantType.

- Gtk::EventController, Gdk::DevicePad
- Since gtkmm 3.96:
Creates a new Gtk::PadController that will associate events from pad to actions.
An empty Glib::RefPtr pad may be provided so the controller manages all pad devices generically. It is discouraged to mix Gtk::PadController objects with empty and non-empty pad argument on the same toplevel window, as execution order is not guaranteed.
The Gtk::PadController is created with no mapped actions. In order to map pad events to actions, use set_action_entries() or set_action().
Be aware that pad events will only be delivered to Gtk::Windows, so adding a pad controller to any other type of widget will not have an effect.
