Glib::Object::_Unregistered::AtkImplementorIface Gtk2::Buildable Glib::Object::_Unregistered::GtkActivatable MNEMONICS
Mnemonics are "memory aids"; in GTK+, a mnemonic is an underlined character which corresponds to a keyboard accelerator. For a button, that means pressing Alt and that key activates the button. For convenience, Gtk2-Perl uses mnemonics by default on widgets that support them. If characters in label string are preceded by an underscore, they are underlined. If you need a literal underscore character in a label, use '__' (two underscores). If you don't want to use mnemonics at all, use the non-mnemonic version explicitly (e.g. "Gtk2::Button::new_with_label"). METHODS
