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").

widget = Gtk2::Button->new

widget = Gtk2::Button->new ($mnemonic)

$mnemonic (string) used to label the widget, see "MNEMONICS"

widget = Gtk2::Button->new_from_stock ($stock_id)

$stock_id (string) creates a new button using the icon and text from the

specified stock item, see Gtk2::Stock

widget = Gtk2::Button->new_with_label ($label)

$label (string) used to label the widget

widget = Gtk2::Button->new_with_mnemonic ($mnemonic)

$mnemonic (string) used to label the widget, see "MNEMONICS"

'focus-on-click' (boolean : default true : readable / writable / private / static-nick / static-blurb)
Whether the button grabs focus when it is clicked with the mouse
