Hi Markus,
Could you please tell me which version of ULC are you using and which JRE?
I assumed that you are using ULC 6.0.4 and hence tested your samples with
that version.

I ran both the classes, I see no difference. The icon defined by the
renderer is drawn in both cases.
However, say I specify only the openIcon. Then the behavior is different in
Swing and ULC.
For closed nodes, Swing shows default icons while ULC shows no icon at all.
So, when you set a renderer in ULCTree which does not specify any icons,
ULCTree should draw default icons.
Is this the problem you are talking about?
The DefaultTreeCellRenderer in Swing takes default icons from L&F and sets
them on the renderer.
The DefaultTreeCellRenderer in ULC does not take default icons from L&F.
You will need an extension to overcome this problem.
I.e. you will have to define MyDefaultTreeCellRenderer extends MyULCLabel
and MyULCLabel extends ULCLabel.
Then in MyUILabel extends UILabel override getTreeCellRendererComponent and
set the default icons for leaf, open, close if no icon is specified.

In Swing, on the DefaultTreeCellRenderer, there is a property
"drawsFocusBorderAroundIcon" which is defined by L&F
UIManager.get("Tree.drawsFocusBorderAroundIcon"). For Metal it is false.
DefaultTreeCellRenderer extends JLabel and overrides the paint() method in
which it considers this property.
This property is not being considered in case of ULC.
You will need an extension to overcome this problem.
I.e. you will have to define MyDefaultTreeCellRenderer extends MyULCLabel
and MyULCLabel extends ULCLabel.
Then in MyUILabel extends UILabel create your own JLabel in
createBasicObject() and override its paint method.
See Swing's DefaultTreeCellRenderer.paint()
>- On a ULCTableTree with a custom cell renderer: The lines of the
>tree are not drawn on the selected row(s). (See class ULCTableTreeTest)
I did setSelectionBackground(Color.white).
I can see the line connecting parent node with child node if that is what
you meant by "lines of the tree".
The color of the lines and the selectionBackground color are the same and
that is the reason you don't see them.
I hope I understood your problem.
>- Setting a default tree icon of the look and feel to null (e.q.
>UIManager.put("Tree.leafIcon", null) ) results in a
>NullPointerException in the TableTree-Widget.
Can you please send me a small snippet and the stack trace?
Doing the above in your ULCTableTreeTest did not give any error.
Thanks and regards,
Janak
