We discovered some Issues / Swing differences on the ULCTree and ULCTableTree:
- Using a custom renderer extended from
DefaultTreeCellRenderer/DefaultTableTreeCellRenderer on ULCTree / ULCTableTree
results in the lost of the default icons provided by the current look&feel.
Using Swing's JTree the default icons are drawn. (See classes SimpleULCTree and
SimpleJTree at the bottom of the mail)
- On a ULCTree with a custom cell renderer (or on the tree column of
ULCTableTree) the focus is drawn differently than the Swing counterpart. In ULC
the icon is inside the focus border.
- On a ULCTableTree with a custom cell renderer: The lines of the tree are not
drawn on the selected row(s). (See class ULCTableTreeTest)
- 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.
Is there a workaround especially for the focus and line drawing issue ?
