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.

You'll have to do it in two steps in order to avoid namespace redeclarations at child level :

SQL> SELECT xmlserialize(document


  2           insertchildxml(


  3             appendChildXML(


  4               xmltype('<A xmlns="namespace" xmlns:def="myns_namespace"><B/></A>')


  5             , '/A'


  6             , xmlelement("C", xmlattributes('attribute' as "attr"))


  7             , 'xmlns="namespace"'


  8             )


  9           , '/A/C'


 10           , '@def:attribute'


 11           , 'def_attribute'


 12           , 'xmlns="namespace" xmlns:def="myns_namespace"'


 13           )


 14           indent


 15         )


 16  FROM dual;




XMLSERIALIZE(DOCUMENTINSERTCHI


--------------------------------------------------------------------------------


<A xmlns="namespace" xmlns:def="myns_namespace">


  <B/>


  <C attr="attribute" def:attribute="def_attribute"/>


</A>

Weird, I really thought I had tried this approach and it didn't work. I must not have commented out another line that I should have. This works, thank you.
