i have a handler class which needs to set text of the tree items in the GUI.
the tree is like
> expandable treeitem
- treeitem 1
- treeitem 2

i want to change the text of "expandable treeItem", "treeitem 1", ....

this seems not to work:

TreeItem clusterItem = selectedForm.getTreeWidget().getTopItem();
clusterItem.setText("gaga");

the clusterItem is set, but not changed

selectedForm is an instanceOf dialog, the GUI i want to change the text.

The tree widget is exposed so i can access it from my handler class

see attachments

what do i do wrong?

Suggest you to refer below Tree Snippet which modify text of the TreeItem at runtime (double click on a TreeItem to get into editor mode)
http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet111.java

Tried adding below line at line 66 & line 88 in above "Snippet111" and it works fine:
tree.getTopItem().setText("Test");

thx, studied it already
did not reflect my case, where i do need to change the text, from another class.
solved it though for initial display by calling the display after changing.
not sure yet if this will work changing stuff after the dialog is displayed already.
