| check | | public String check(JComponent component)(Code) | | Returns a non-null value if the check failed. Sometimes the return value
is used (for example, it is displayed as a tooltip for menu-items);

the return value). An advanced use of an EnableCheck is simply to change
some property of a menu item (such as the text), as it is called when
menu items are displayed.
