[news.eclipse.platform.swt] Re: Layouts, minimal height and grabExcessXX

["Carolyn MacLeod" <Carolyn_MacLeod@xxxxxxxxxx>]

It might be easier to use a FormLayout, because you will have a bit more 
control.
For example, here is a snippet.
Hope this helps,
Carolyn

import org.eclipse.swt.*;
import org.eclipse.swt.graphics.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;

public class FormWithTables {
 public static void main (String [] args) {
  Display display = new Display ();
  Shell shell = new Shell (display);
  FormLayout formLayout = new FormLayout ();
  formLayout.marginWidth = 4;
  formLayout.marginHeight = 4;
  formLayout.spacing = 4;
  shell.setLayout (formLayout);

  Button button1 = new Button (shell, SWT.PUSH);
  button1.setText ("button1");
  Point size = button1.computeSize(SWT.DEFAULT, SWT.DEFAULT);
  int center = size.y / 2;

  Table table0 = new Table (shell, SWT.BORDER);
  table0.setLinesVisible (true);
  for (int i = 0; i < 5; i++) {
  TableItem tableItem = new TableItem (table0, SWT.NONE);
   tableItem.setText ("Item" + i);
  }

  Table table2 = new Table (shell, SWT.BORDER);
  table2.setLinesVisible (true);
  for (int i = 0; i < 5; i++) {
  TableItem tableItem = new TableItem (table2, SWT.NONE);
   tableItem.setText ("Item" + i);
  }

  FormData data = new FormData ();
  data.top = new FormAttachment (0, 0);
  data.bottom = new FormAttachment (button1, 0, SWT.DEFAULT);
  table0.setLayoutData (data);

  data = new FormData ();
  data.left = new FormAttachment (table0, 0, SWT.CENTER);
  data.top = new FormAttachment (50, -center);
  button1.setLayoutData (data);

  data = new FormData ();
  data.top = new FormAttachment (button1, 0, SWT.DEFAULT);
  data.bottom = new FormAttachment (100, 0);
  table2.setLayoutData (data);

  shell.pack ();
  shell.open ();

  while (!shell.isDisposed ()) {
   if (!display.readAndDispatch ())
    display.sleep ();
  }
  display.dispose ();
 }
}
