Q: How do I get an SWT layout to display properly?

A: The size of a control sometimes defaults to zero width and height – this drives us all mad. The solution lies in the composite, rather than the control...

Method 1: call the layout() method

Composite parent = new Composite(grandParent, SWT.NONE);
...
(create controls)
...
parent.layout();

Method 2: resize the composite

• programatically with parent.setSize(...)?
• manually by the user
