Instances of this class are controls which are capable of containing other controls. <dl> <dt><b>Styles:</b></dt> <dd>NO_BACKGROUND, NO_FOCUS, NO_MERGE_PAINTS, NO_REDRAW_RESIZE, NO_RADIO_GROUP, EMBEDDED, DOUBLE_BUFFERED</dd> <dt><b>Events:</b></dt> <dd>(none)</dd> </dl> <p> Note: The <code>NO_BACKGROUND</code>, <code>NO_FOCUS</code>, <code>NO_MERGE_PAINTS</code>, and <code>NO_REDRAW_RESIZE</code> styles are intended for use with <code>Canvas</code>. They can be used with <code>Composite</code> if you are drawing your own, but their behavior is undefined if they are used with subclasses of <code>Composite</code> other than <code>Canvas</code>. </p><p> Note: The <code>CENTER</code> style, although undefined for composites, has the same value as <code>EMBEDDED</code> (which is used to embed widgets from other widget toolkits into SWT). On some operating systems (GTK, Motif), this may cause the children of this composite to be obscured. The <code>EMBEDDED</code> style is for use by other widget toolkits and should normally never be used. </p><p> This class may be subclassed by custom control implementors who are building controls that are constructed from aggregates of other controls. </p>
