Hide horizontal and vertical lines in a JTree

843806Oct 23 2007 — edited Oct 24 2007

Hi,

suppose we have three JTrees in a Windows L&F where the second one shall not show any vertical or horizontal lines for a node. If this restriction would be true for all three JTrees one could invoke

UIManager.put("Tree.paintLines", Boolean.FALSE)

.

However only the second one must not show any lines. I tried something like

tree.putClientProperty("Tree.paintLines", Boolean.FALSE);
tree.updateUI();

But unfortunately this does not work as the lines are still shown. Furthermore we need to set "on/off" the lines dynamically dependend on the user data.

Does anyone have a clue to solve this problem?

Thx.
