Class RowData

java.lang.Object
org.eclipse.swt.layout.RowData
public final class RowData extends Object
Each control controlled by a RowLayout can have its initial width and height specified by setting a RowData object into the control.

The following code uses a RowData object to change the initial size of a Button in a Shell: 

                Display display = new Display();
                Shell shell = new Shell(display);
                shell.setLayout(new RowLayout());
                Button button1 = new Button(shell, SWT.PUSH);
                button1.setText("Button 1");
                button1.setLayoutData(new RowData(50, 40));
