Hi,<br />
I use the class MyJTree with one MyDefaultMutableTreeNode (as a root) in its MyDefaultTreeModel.<br />
Where:<br />
<br />
MyJTree extends JTree<br />
MyDefaultMutableTreeNode extends DefaultMutableTreeNode<br />
MyDefaultTreeModel extends DefaultTreeModel<br />
<br />
When I add a child node, it only seen if I double-click the root.<br />
I want it to be seen automatically.<br />
How do I do this easily?<br />
Thanks.

Hi,

How do I do this easily?

Add a DefaultMutableTreeNode to the root

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
