Member Typedef Documentation

SlotShortcut

using Gtk::CallbackAction::SlotShortcut = sigc::slot<bool(Widget&, const Glib::VariantBase&)>

Slot for shortcuts based on user callbacks.

For instance:

void on_shortcut(Widget& widget, const Glib::VariantBase& args);

Parameters

widget	The widget passed to the activation.
args	The arguments passed to the activation. Can be empty, if there are no arguments.
