Thanks Steve! I'll get a stand alone testcase and will file a defect.

Linux GTK had some wierd issues involving deferring work until the event loop.  You might be seeing this.  Does inserting a display.readAndDispatch() fix the problem?  In any case, you'll have to give us more to work with (ie. some code we can test and debug).  Please enter a bug report with a stand alone snippet.  Thanks.

Subject	[platform-swt-dev] SWT Tree performance

Hi There,
 
I have a testcase where in expanding a  SWT Tree node at 5th level fails when using a GUI automation tool. For e.g, expanding the node "E" in the sequence
 
A->B->C->D->E .
 
The failure is because the automation tool is timing out before it expands the tree node D. But, if I expand the nodes upto "E"  manually, collapse everything again and then use the automation tool to playback the above case, it works, i.e, the tool can expand the node "E" (after expanding all the preant nodes leading E). Basically, there is no time out if the Tree nodes are expanded and collapsed once.
 
I can't suspect on the automation tool, because it is just calling the method showItem() from org.eclipse.swt.widgets.Tree package to expand (or make the node visible).
 
Could this, taking more time to expand, is an SWT problem? This problem is seen on Linux.
 
Thanks and regards,
Suma.
