[news.eclipse.platform.swt] Re: Getting Absolute Coordinates of a tree i

[Harry_sim@xxxxxxxxx (Harry)]

Hi Tom

I am trying to simulate the Mouse click event on the tree item by getting 
the absolute coordinates of the tree item..

Right now I am using tree.getItem[0].getBounds() to get the coordinates of 
the tree item relative to the parent....

But I want to convert these coordinates to screen level coordinates so 
that I can simulate the mouse event using Display.post().

  Display.post method is used to simulate the mouse events....which 
requires the absolute screen coordinates where mouse is to be clicked...

 So to get the absolute coordinates..display.map is used as follows..
where parent is the composite from CreatePartControl(Composite parent) 
method...

final Point point = parent.getDisplay().map(treeViewer.getControl(), null, 
new Point(treeViewer.getTree().getItem(0).getBounds().x,
           treeViewer.getTree().getItem(0).getBounds().y)) ;



event = new Event();
               event.type = SWT.MouseDown;
               event.x = point.x;
               event.y = point.y;
               parent.getDisplay().post(event);


But the mouse is being clicked somewhere not on the first tree item..

Thanks
Harry
