Text Editor Using CL_GUI_TEXTEDIT Displaying Text ... - SAP Community

In ABAP (Advanced Business Application Programming), cl_gui_textedit is a class used for creating and manipulating text editor controls in Object-Oriented ABAP (OOABAP). This class is part of the SAP GUI (Graphical User Interface) framework and is specifically designed for handling text editing within SAP GUI applications. 

Here's a brief explanation of how you can use cl_gui_textedit in OOABAP: 

cl_gui_custom_container class is used to embed custom controls or UI elements within a container on the SAP GUI screen. This class is part of the Object-Oriented ABAP (OOABAP) programming paradigm. The cl_gui_custom_container class is often used in combination with other classes and methods to create interactive and customized user interfaces. 

Creating an Instance:  

To use the cl_gui_textedit and cl_gui_custom_container class, you first need to create an instance of the class. You can do this using the create object statement. 

Create screen 101 (Modal Screen in this case) by double clicking on “101”. 

Create a custom control on the screen with the name “CONTAINER”. 

Now, add the logic for displaying the edit control in PBO and PAI Modules of screen 101. 

In pbo, create object container go_custom. Then create text editor object by exporting the container go_custom. 

    if go_custom initial 

Create object for go_textedit 

The cl_gui_textedit class in ABAP is used for displaying and editing text. The set_text_as_r3table method is used to set the content of the text editor as a table that is typically used in SAP R/3 systems. This method allows you to display tabular data within a cl_gui_textedit control in an Object-Oriented ABAP (OOABAP) program. 

The method set_readonly_mode is used to set the read-only mode of the text editor. 

read-only mode; eq 0: off; ne 0: on
