Align a TableViewer and TreeViewer

Question

I am creating an SWT application with two TreeViewers and a TableViewer in between them.

The TableViewer contains images in each row that indicate something about the date in that row of the TreeViewer.

However the problem is that the images in the TableViewer are not properly aligning with the rows in the TreeViewer. Is there any way for me to ensure that their rows stay exactly leveld?

Thanks

You can change the way the height of a row is measured by overriding the behaviour of the "measuring method", i.e. adding a Listener to SWT.MeasureItem. There is a good example here. Just use the height of the icon you use in the TreeViewer plus maybe a couple of border pixels.

Here is the important code part:

Display display = new Display();
Shell shell = new Shell(display);
shell.setBounds(10,10,200,250);
final Table table = new Table(shell, SWT.NONE);
table.setBounds(10,10,150,200);
table.setLinesVisible(true);
for (int i = 0; i < 5; i++) {
   new TableItem(table, SWT.NONE).setText("item " + i);
}
table.addListener(SWT.MeasureItem, new Listener() {
   public void handleEvent(Event event) {
      int clientWidth = table.getClientArea().width;
      event.height = event.gc.getFontMetrics().getHeight() * 2;
      event.width = clientWidth * 2;
   }
});
shell.open();
while (!shell.isDisposed()) {
   if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
