Label.newWithMnemonic
gtk.label.Label newWithMnemonic(string str = null)Creates a new [gtk.label.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.Label.setMnemonicWidget].
If [gtk.label.Label.setMnemonicWidget] is not called, then the first activatable ancestor of the [gtk.label.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.
Parameters
str | The text of the label, with an underscore in front of the mnemonic character |
