Gtk.Expander.prototype.get_label

function get_label():String {
    // Gjs wrapper for gtk_expander_get_label()
}

Fetches the text from a label widget including any embedded underlines indicating mnemonics and Pango markup, as set by Gtk.set_label. If the label text has not been set the return value will be null. This will be the case if you create an empty button with Gtk.Button.new to use as a container.

Note that this function behaved differently in versions prior to 2.14 and used to return the label text stripped of embedded underlines indicating mnemonics and Pango markup. This problem can be avoided by fetching the label text directly from the label widget.

Since 2.4
