You can work with SWT layout managers with the visual editor for
Java.
See the following topics for more information:
Using RowLayout (SWT)
The SWT RowLayout layout manager lays out its components in rows, but is more robust than FillLayout.
Using GridLayout (SWT)
You can use the GridLayout with SWT containers to arrange widgets in a grid arrangement.
Using FillLayout (SWT)
The visual editor makes it easy to work with the SWT FillLayout manager.
Using FormLayout (SWT)
You can set an SWT container to use the SWT FormLayout layout manager, but the visual editor does not provide additional visual support.
