For the execution of user dialogs, you need input and output services that can be accessed through the user interface (UI). The user interface is used for interaction between the user and the program. If parts of the user interface are displayed in the GUI window on the screen, this is a graphical user interface (GUI). SAP GUI is a specific implementation that uses dynpros to execute dialog-based applications, which are installed in the presentation layer on the server as underlying software components of ABAP. It contains all the control elements needed to execute the dialog between the user and the program. Follow the official account: SAP Technical for more content

Let's take a look at the graphics

On the screen, SAP GUI displays the screen of dynpro (dynamic programs) in the GUI window. The screen can contain screen elements for displaying content or for receiving user actions. Use Layout Editor in the Screen Painter tool to process the screen and its screen elements. Each screen element has properties that are statically predefined in Screen Painter, and some of them can be modified dynamically in ABAP programs.

As another part of the graphical user interface, each standard window contains a menu bar, a standard toolbar, and an application toolbar. The GUI window that appears as a modal dialog box contains only the application toolbar. Bar charts are independent components of the ABAP program and are grouped together in a GUI state. In addition, they are assigned to the dynpro when the GUI state is set. In addition to graphical elements, function keys are also part of the user interface. They are defined as independent components of the ABAP program and are therefore part of the GUI state. Use the Menu Painter tool to deal with the components of the GUI state and the GUI state itself. In most cases, the control elements displayed in the user interface are linked to the functional code and can be evaluated in the ABAP program. A description of the current GUI status can be found in the system field sy-pfkey.

The GUI window in SAP GUI is completed when it has a title bar and a status bar. The title bar is also edited using Menu Painter and contains the title of the GUI window. The status bar displays the information that can be transferred during the execution of the ABAP program using the MESSAGE statement. In addition, it contains system information that can be shown or hidden using the icon on the right side of the column.
