Hi Folks,

Our requirement is in a report, we have to keep a button. On clicking this button, a text editor must get opened. User shall enter some texts related to a particular document say a sale order. When he presses the save button, the entered text shall get saved.

In the future, whenever we call that sale order, these texts must be present there in the editir. Can anybody throw some light on this.

Use fm EDIT_TEXT to do that or see the code used by SO10 (include MSSCEI00).

Why dont you use a subscreen to do the same

you can use the class cl_gui_textedit which will give you many options to do various operations on the subscreen

Also use READ_TEXT and SAVE_TEXT to update the text based on your requirement.

Hi,

have a look into function group STXD. The function modules, which you need are:

init_text, save_text, delete_text, read_text.

In your SO you will save an object ID, which will be used to retrieve the text when the SO is displayed.

regards, Ulli

Hi,

I have seen replies from you and Max.

Thankx for your suggestions.

I have done this technique already. The reqt is like we need to implement this text editor using Classes & Methods instead using function modules like edit_text, read_text.

Hope you got it. If you all have any solution please let me know.

Try to see the program demo RSDEMO_DRAG_DROP_EDIT_TREE

Here it should find an example on how to use the class cl_gui_textedit.

Hi Manish,

When I copied your code and activated its showing error in the following areas:

PARAMETERS : p_cacct LIKE fkkvkp-vkont.

Field "FKKVKP-VKONT" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement.

Also what does the INCLUDE zsw_cic_contract_acct_top contain.

Kindly help.

Re: Text Editor

Former Member — Wed, 18 Oct 2006 10:24:24 GMT

here is the way to save the data from text editor using classesinto an Internal Table and then u can use it your own way..

***********************************************

report zsd_0001 .

data:

dockingleft type ref to cl_gui_docking_container,

text_editor type ref to cl_gui_textedit,

repid type syrepid.

data: textlines type table of tline-tdline,

wa_text type tline-tdline.

parameters: p_check.

at selection-screen output.

repid = sy-repid.

create object dockingleft

exporting repid = repid

dynnr = sy-dynnr

side = dockingleft->dock_at_left

extension = 1070.

create object text_editor

exporting

parent = dockingleft.

start-of-selection.

call method text_editor->get_text_as_r3table

importing

table = textlines

exceptions

others = 1.

loop at textlines into wa_text.

write:/ wa_text.

endloop.

Hi,

There is an excellent Blog for this by Igor Barbaric some time ago.

Please see> <a href="/people/igor.barbaric/blog/2005/06/06/the-standard-text-editor-oo-abap-cfw-class Standard Text Editor (OO ABAP CFW class)</a>

I have implemented this class and used it for a sales order scenario. It does work perfectly.
