GUI Designer Part Interface.
Each KPart that wants to act as a GUI Designer must implement this interface.
It defines necessary signals to communicate with an IDE and abstract virtual
functions to determine designer type.

Parts that implement this interface must emit its signals when necessary.
See signals documentation for an explanation on when to emit those.

If a part which can "design" user interface files of a certain mimetype
implements this interface and sets itself as a default handler for that 
mimetype then it becomes automatically integrated into TDevelop IDE.
