shell.setBackgroundMode(SWT.INHERIT_FORCE);

constant to indicate that an attribute (such as background) is inherited by all children.
public static void main(String[] args)
{
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new GridLayout(1, false));
shell.setText("StackOverflow");
shell.setBackground(display.getSystemColor(SWT.COLOR_BLUE));
shell.setBackgroundMode(SWT.INHERIT_FORCE);
new Button(shell, SWT.PUSH).setText("Button");
new Label(shell, SWT.NONE).setText("Label");
shell.pack();
shell.open();
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
{
display.sleep();
}
}
display.dispose();
}
