[ CCode ( has_construct_function = false , type = "GtkWidget*" ) ]
public Label.with_mnemonic (string? str)

Creates a new `GtkLabel`, 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 [method@Gtk.Label.set_mnemonic_widget].

If [method@Gtk.Label.set_mnemonic_widget] is not called, then the first activatable ancestor of the `GtkLabel` 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.
