Gtk.Label.new_with_mnemonic

function new_with_mnemonic(str:String):Gtk.Widget {
    // Gjs wrapper for gtk_label_new_with_mnemonic()
}

Creates a new Gtk.Label, containing the text in str.

If characters in str are preceded by an underscore, they are underlined. If you need a literal underscore character in a label, use '__' (two underscores). The first underlined character represents a keyboard accelerator called a mnemonic. The mnemonic key can be used to activate another widget, chosen automatically, or explicitly using Gtk.Label.prototype.set_mnemonic_widget.

If Gtk.Label.prototype.set_mnemonic_widget is not called, then the first activatable ancestor of the Gtk.Label will be chosen as the mnemonic widget. For instance, if the label is inside a button or menu item, the button or menu item will automatically become the mnemonic widget and be activated by the mnemonic.
