Graphical Editing Framework (GEF) is a framework that was developed for the Eclipse platform. It is used to create graphical editors for various diagrams like electrical networks or tree diagrams. Such diagrams offer easy editing capabilities for data in specific domains and are well suited as a graphical representation of that data. GEF editors can be used inside an Eclipse RCP application, the application framework offered by Eclipse. Usually, GEF is used as a part of the Graphical Modeling Framework (GMF) which combines the Eclipse Modeling Framework (EMF) and GEF to create the code for both the data model and the diagram editor. ==Structure== Editors generated with GEF consist of the following components: * The diagram editor including tool palette * Figures which graphically represent the underlying data model elements * EditParts which match figures and their respective model elements * Request objects for user input * EditPolicy objects which evaluate the requests and create appropriate command objects * Command objects that edit the model and provide undo-redo 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Graphical Editing Framework」の詳細全文を読む スポンサード リンク
