Icon with StyledTreeCellRenderer

[stars]

Hi,

I'm using StyledTreeCellRenderer in JTree. There is a strange behaviour that I reproduce into Jide examples (@see attachment).
The UserObject from node is updated to the customizeStyledLabel add an icon. The icon is printed but the text is truncated with 3 dots.

In StyledLabelDemo.java, expand the 2nd error node, clicks on button then collapses/expands this node: icon is well painted but text is printed with 3 dots. If node is not expanded before UserObject modification, the display is correct.
Any ideas ?

Regards,

The reason is that BasicTreeUI has a cache to store the bounds of the paths and it does not trigger recalculation while setting object. I modified your test case to customize the BasicTreeUI to make it work FYI.
