hello everybody:
I am loooking for a way to add a node (a child) under the node that is currently selected in the tree. I am currently able to add a node under the root node, but the problem is that I do not know how to get a pointer on the current node.
who can help me?
Thank you very much

in this code ,you can add a node in the root ,but you can not add node in what your chioce.
this is dirtree.xml:
<entry name="/" type="dir" >
<entry type="dir" name="usr">
<entry type="dir" name="bin">
<entry type="file" name="awk"/>
<entry type="file" name="grep"/>
<entry type="file" name="perl"/>
<entry type="file" name="bash"/>
</entry>
</entry>
<entry type="dir" name="var">
<entry type="dir" name="tmp"/>
<entry type="dir" name="log"/>
</entry>
<entry type="dir" name="home">
<entry type="dir" name="root">
<entry type="file" name=".profile"/>
</entry>
</entry>
<entry type="dir" name="lib"/>
<entry type="dir" name="etc"/>
</entry>
