Additional Inherited Members
Public Types inherited from Gtk::Expression< T >
using	ValueType = T

Public Types inherited from Gtk::ExpressionBase
using	SlotNotify = sigc::slot< void()>
	For instance: void on_notify();. More...

Public Member Functions inherited from Gtk::Expression< T >
std::optional< T >	evaluate (const Glib::RefPtr< Glib::ObjectBase >& this_)
