set_revealed
Description:
Sets whether the `GtkInfoBar` is revealed.
Changing this will make this reveal or conceal itself via a sliding transition.
Note: this does not show or hide this in the [property@Gtk.Widget:visible] sense, so revealing has no effect if [property@Gtk.Widget:visible] is false.
Parameters:
