So I have a JPanel that is a container for a number of JLabels. Let'ssay I have a reference for a particular JLabel that is in the JPanel'scomponent list. How can I find the index of the JLabel in theJPanel..? JPanel has a getComponent(int index). What about theoposite..?Sorry for the trouble..

Every time a element were added or deleted, the embeddedindex number would have to be updated in every Component.  It would befaster just to scan the component list when you need the reverseindex.-- Roedy Green Canadian Mind ProductsThe Java Glossaryhttp://mindprod.com

So if you extended Container, you could notaccess the array of children to do the scan.-- Roedy Green Canadian Mind ProductsThe Java Glossaryhttp://mindprod.com
