Re: How to determine if a

  To: comp.lang.java.gui
After some trial I figured that one can cast the items added to the
JMenuBar to a Container and use the getComponent() and
getComponentCount() to iterate through the items inside that container.
 The only exception was the JMenu object.  Calling the
getComponentCount() method would always return 0.

After some reading and browsing the source code for the JMenu class I
noticed that a JMenu does not behave like other containers.  One need
to call the method getMenuComponent() or getMenuComponentCount() to
iterate through the subcomponents of the menu.  So I placed an if
statement to deal with this specific class using the alternate methods.


Just in case I went about this the long way, does anyone have any
better suggestions?
