Problems with method "CALL_METHOD"

Former Member — Thu, 27 Dec 2007 18:31:19 GMT

Hello there ...

I want to get a text from a Custom Control and put it in a table. To do it I use the method get_text_as_r3table and this method calls another method : call_method as follows :

CALL METHOD call_method

EXPORTING

method = 'SaveSelectedTextToDP'

p_count = 1

p1 = m_dp_handle.

The problem is that the text is only saved when I select it, because of this statement "'SaveSelectedTextToDP'".

So my question is ... Is there a way to get the text from this custom control without selecting it ?? Maybe something like "SaveTextToDP" ?! I couldn't find anything like it ...

Thanks in advance ...

Pedro,

"from a Custom Control" ??

What kind of Custom Control? Is this an SAP-provided control? Or a Windows OS control? Or VB, C++, etc?

Hi Pedro,

I assume you are using the method get_text_as_r3table belonging to the class CL_GUI_TEXTEDIT.

If so, there should be no problem retrieving the text entered from exporting parameter TABLE.

Please ensure the importing flag (to the method) ONLY_WHEN_MODIFIED is left as ' ' and not checked.

Hope this helps.

Regards,

Aditya

Hi Aditya,

My custom control is like a text editor, in fact i'm using the classes of the new abap editor, that Thomas Jung develop. I inherit this editor from this class "cl_gui_control" and my method "get_text_as_r3table" is declared this way :

I tried to use only_when_modified = '', but the problem is the same.

Is there any function or method that selects all the text ?! Because it's very boring having to select all the text manually when I want to save my text =/
