Graphic Type-Specific Method Calls

Use

The graphics proxy classes can implement other methods in addition to the general interface methods; for example, methods for node handling (ADD_NODE, SET/GET_PARENT and so on) may be useful for hierarchy graphics. If a graphics proxy provides such methods they are documented in the graphics proxy-specific documentation.

The interface for graphics proxies is general and can be used independently of the required graphic type (business graphic, hierarchy graphic and so on). The graphic type is determined by the selection of the graphics proxy class that implements the interface. An appropriate interface should be defined for every graphic type (for example, IF_GP_HIER for hierarchy graphics) so that different implementations can use the same method names.

Integration

The black dots to the right of the graphics proxy are the ports. The customizing objects on the right CL_CU_DIAGRAM, CL_CU_DISPLAY_CONTEXT, CL_CU_DRAWING_AREA and so on are assigned to the ports.
