BSP: BTF editor example, Non Model View Controller

[thomas_jung]

Introduction

Recently I received an Email from Marco Nickel pertaining to a past weblog I had done on BSP Developer's Journal Part XVI - Using the BTF Editor.  Marco was looking for a BTF example that wasn't implemented in Model View Controller.  Quite frankly I haven't coded much that wasn't MVC in quite some time.  Let's hope my Non MVC BSP programming skills aren't quite as rusty as my German is. 

• event handler for data retrieval

****If we don't have any data coming in from a previous event,

****then we want to initialize it with some default text.

****This could also be some code to load text from the database.

IF s_documentdata-btf_doc IS INITIAL.

   DATA: text(25) TYPE c.

   DATA: l_text TYPE xstring.

   text = 'This is test text'.

   FIELD-SYMBOLS:

• event handler for checking and processing user input and

• for defining navigation

****Perform this code before we handle any events.  Regardless of the event,

****we have to bring the editor content back in to keep it.

• Read data from editor:

  DATA: editor TYPE REF TO cl_btf_bsp_editor.

  editor ?= cl_btf_bsp_manager=>get_data( request = request

                                          name     = 'editor'

                                          id       = 'btf1' ).

  IF editor IS NOT INITIAL.

    s_documentdata-btf_doc = editor->document.

  ENDIF.

Closing

I hope that this little example has been a useful addition to the content that already exists on BTF.  At the very least it might be the starting point for further questions.
