Mark treeNode as selected (Swing)

I have a simple JTree.
I set it's selected node in the code via setSelectionPath().

Everything works fine for that but what I want is that the respective node (the end of my path) is highlighted as if the user had clicked on it with the mouse so that there is also a visual feedback in the tree itself to indicate which node is selected.

Greetings Raven

EDIT:
How I want it to look (just like it looks when selecting a node with the mouse Properly highlighted (after selection with mouse)

How it currently looks after selecting node via program Current result after selecting node via program

Solution

  • I found my problem:
    I was refreshing the content of my tree when selecting the pane where the tree is located on.
    But instead of just updating it's nodes I recreated the complete model and that was the problem.
    The path I was using was a path of the old model and this is the reason why the path couldn't be properly selected in the new tree. I switched to the approach of just updating the model and now setSelectionPath() has the effect I wanted it to have.
