Help!What should I handle the selectionListenner of my Tree.

Question

In our project,The gui is divided into two parts by a splitpane.In left part,there is a tree which lists many functions by leaf nodes,the right part will show the data needed.I want to add a new module to the right part when one tree node is clicked.When another node is clicked then another component will be added.
What should I do with the selectionListener to guarantee adding the correct module into right part associated to the corresponding function node?

Hi,
You need to create your own component X (say extending JPanel) and
add the following to the listener method.
JRootPane itsParent = y.getRootPane();
//y is the current instance of X
itsParent.getContentPane().remove(y);
x = new X(); //(A new instance of X)
getContentPane().add(x);
validate();
Of course you have to put logic to verify that y exists, before removing it.
Hope this helps.
