Method Detail

check

public java.lang.String check(javax.swing.JComponent component)

Description copied from interface: EnableCheck

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.

an error message if the check failed, or null if the check passed
