Activating/Deactivating the Graphics Proxy

Purpose

The graphics proxy has to be activated to display the graphic.

It can be deactivated to make the graphic invisible without destroying the graphics proxy.

Prerequisites

The application must have created the graphics proxy and the parameters must have been set.

Process Flow

Activating the graphics proxy

The application calls the method ACTIVATE in IF_GRAPHIC_PROXY. The graphics proxy subscribes to the multiplexer and to the data container if it has not already done so. After subscription it reads the data from the data container, checks customizing, prepares this information for the graphics product at the front end and sends the information to the graphic.

Deactivating the graphics proxy

If a graphic is to be made invisible without destroying the graphics proxy object then the application calls the method DEACTIVATE in IF_GRAPHIC_PROXY. The graphics proxy cancels its subscription with the multiplexer - that is, it reduces the search quantity of the multiplexer (performance).

Result

When the graphics proxy is activated the graphic is displayed.

When the graphics proxy is deactivated the graphic is invisible.
