It can be frustrating to suddenly want a group instead of a composite after you have already completed the design of the composite. It is very easy to remedy this using the professional version of the Designer.
The Designer allows you to morph similar controls from one type to another. When a control is morphed from one type to another, the properties that are the same between the two types are kept. This allows quick design changes without having to recreate all the controls.
To morph a control from one type to another, right-click on the control and select a control type to morph to from the Morphing cascading menu as shown below.
There are numerous control types that are able to morph into other types. Below is a list of the morphs that are possible with SWT controls. A bi-directional arrow means that the morph can go both ways. A list of control types with bidirectional arrows between them means that one of the types can morph to any of the other types.
