View Full Version : Tree with Panel as TreeNode

30 Dec 2009, 4:33 AM

I'd like to ask how I can insert a panel as a TreeNode? I'm building an examination page where stutured questions are involved. I need the tree to show the stucture. As for the treenode, a panel is necessary because I will contain all the questions metadata (FormPanel) and editor (HTMLEditor).

Thanks in advance.

Theoretically that's possible, but I would advise against it (it would probably use up a lot of resources and you have to take care to not create unwanted memory leaks when moving or deleting nodes).

I would only display the data in the treenode without using any components (optionally using a different TreeNodeUI to format the data).

Next, I would write a different TreeEditor that displays the panel as an editor on top of the current node.

Thanks for the thought...

One more thing... Is there any example on how to build the custom TreeEditor?
