• 77 Line code implementation ABAP ALV Double click event handling in

The previous step in this tutorial , From interpretation BDC Auto generated code , Explain SAPGUI Part of the program , We introduce a typical inclusion Screen The in SAPGUI Operating in the environment ABAP Components of the program , It mainly introduces some theoretical knowledge .

In this article, we begin to practice , Introduce how to do it yourself , Create a containing Screen That is, the user interface ABAP Program .

This program is very simple , The appearance is as follows ：

We can enter something in the input text box , such as 1234, Then click the execute button or F8 Shortcut key , The program will pop up a dialog box , Print out what we entered 1234：

below Is the detailed implementation steps .
