I have treeviewer, hooking own contentprovider and labelprovider, in contentprovider, I implement getChildren, getElement, returns my model object, model object has toString method, the labelprovider implements getText, getImage. When I record select last tree node for my test case, RCPTT gives me:
get-view Home | get-tree | select [get-item "" | get-item "" -index 2]
It uses index to find tree. But I want to use tree node name to find tree node, like the follows:
get-view Home | get-tree | select [get-item "Home" | get-item "Book1" ]
But it failed, it said [Home, Book1] can not be found.
I checked detail message and found there is no name for each tree item in swt.info block
swt.info
{
Tree()
{
Item()
{
Item()
Item()
Item()
}
}
}
I also checked sample rcpmail code, it gave me treenode name during recording the selection;
get-view Mailboxes | get-tree | select "me@this.com"
I would like to know how rcptt get treenode name in swt.info, which API RCPTT check it? Where is the implementation for it. Maybe I need to tweak my code to get it work.

My solution works!!!
Here is the script, maybe not expert level script, any comments or simplification of my script are welcome and appreciated:
Requirement: Given tree node name, find tree node one level under root node in the View, name "Home", then select ( applies to treeitem text is empty, like me using OwnerDrawLabelProvider)
**
* the procedure to find first matching node one level under root given node name
*/
proc "find-node-under-root" [val nodeName]
{
let [val root [get-view Home | get-tree | get-item ""] ]
{
let [val count [ $root | get-property childCount -raw]]
{
loop [val index [int 0]]
{
let [val nodename [ $root | get-item "" -index $index | get-object |invoke getData | invoke toString ] ]
{
if [ $nodename |eq $nodeName]
{
$root | get-item "" -index $index
}
-else
{
if [ $index | lt $count ]
{
recur [ $index | plus 1]
}
}
}
}
}
}
}
select-item [ find-node-under-root "Book1" ]
Result: Book1 node under root, "Home", is selected
