com.volantis.mcs.eclipse.ab.editors.layout.FormatComposite
The superclass for all FormatComposites. Extend this and implement getTopLevel() to return the top-level composite of the actual specialization. This returned Composite is then placed inside a Group widget by this superclass. Subclasses should define their own public void dispose() methods to dispose of any system resources not taken care of by super.dispose(), and also to remove any listeners that the FormatComposite registered with ODOMElements. An alternative design would be to separate ISelectionProvider from FormatComposite by providing a FormatViewer that is a ContentViewer. The relationship between FormatViewer and FormatComposite is effectively the same as that between TreeViewer and Tree. This would mean that setSelection would take an array of FormatComposites rather than elements as well as other similar changes. However, the only real benefit from this alternative is that it is consistent with the way Eclipse JFace/SWT works. It would be slower and use more memory. On the other hand since there would be content and label providers the design may be more flexible. On balance it is not likely that FormatComposite will need to be more flexible - unlike a Tree, FormatComposite is designed specifically for FormatComposite objects that have a well defined relationship with particular kinds of layout element. The FormatViewer/FormatComposite approach would also take longer to implement and as usual time is lacking. FormatComposites create and maintain their own layout. Setting a Layout on a FormatComposite will cause an UnssuportedOperationException. This is necessary because the layout is used to represent the cells of the FormatComposite so it must have control over it. The layout of a FormatComposite is a GridLayout. @todo Remove the mouse specific selection support & replace withgeneric keyboard & mouse
