Display Logo on Screen

By Suresh Kumar Parvathaneni

You can display logo(s) on your screen using the custom control function. A custom control is an area on the screen, created using the screen painter. Custom controls are used to embed controls. Container controls are instances of special global classes from the SAP Control Framework. The global class for custom controls is called CL_GUI_CUSTOM_CONTAINER. To link a custom control to a container control, pass the custom control name to the CONTAINER_NAME parameter of the container control constructor when you instantiate it. The following is a sample program to demonstrate the logo display using the custom control. This program was written in SAP4.6C. Design a screen with the custom control, by name PICTURE_CONTAINER. It has the following flow logic:

PROCESS BEFORE OUTPUT.
MODULE STATUS_0100.
*
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.

The GUI status SCREEN100 has the functions BACK, EXIT, and CANCEL (all with type E).
