Flow text within selection sceen

Former Member — Tue, 17 Jun 2008 13:45:11 GMT

Hey, Folks.

Is there a chance to have an input field with more lines on a selection screen? Like an input text box on va01-> head-> texts?

Let's say, users can type in a text which is printed on a form.

thank you for any ideas.

Use class 'CL_GUI_TEXTEDIT'.

Check the program 'DEMO_CUSTOM_CONTROL'

Does this work on Selection Screens, too?

You need to use class CL_GUI_TEXTEDIT or if you are working on ECC6 (Netweaver7) then please check demo program RSMDS_DEMO.

Pl. follow the steps:

Step 1 - Create a sub-screen using screen painter in the repot program.

Step 2 - Set the size of the sub-screen.

Step 3 - Place a custom control on the screen set its name to u2018C_CONTAINERu2019 and set the size of the custom control to the size of the required multi-line input output field.

Step 4 - Save and activate the sub-screen.

Step 5 - Code the Data Declarations

Code snippet: -

Create a reference to the custom control

DATA: v_text TYPE REF TO c_textedit_control.

DATA: v_line(72),

internal table to hold user entered text

i_tab LIKE STANDARD TABLE OF v_line.

Step 6 - Define Selection Screen.

Displaying a sub-screen in a sub-screen area on a selection screen is a special case of a tab-strip control on a selection screen. A sub-screen area on a selection screen, is defined using following statements:

SELECTION-SCREEN: BEGIN OF TABBED BLOCK <sub_area>

FOR <n> LINES,

END OF BLOCK <sub_area>.

Code snippet: -

PARAMETER matnr LIKE mara-matnr.

Data transfer error. Your installation is faulty.

SELECTION-SCREEN: BEGIN OF TABBED BLOCK sub FOR 6 LINES,

END OF BLOCK sub.

SELECT-OPTION DATE FOR SY-DATUM.

Step 7 - Before the selection screen is displayed, the subscreen must be assigned to the subscreen area <sub_area>. This is done in the initialization event by using the components PROG and DYNNR of the structure <sub_area>, which is created automatically when the subscreen area is defined . The program name of the sub-screen screen is assigned to the component PROG, and its screen number to DYNNR.

Then Create the Multi-line Input Output custome control instance and set its properties.

The Constructor parameters are explained below

a) wordwrap_mode can have following values.

WORDWRAP_OFF = 0: No line break

WORDWRAP_AT_WINDOW_BORDER = 1: Line break at the edge of the window

WORDWRAP_AT_FIXED_POSITION = 2: Line break at a fixed position

b) wordwrap_position Position for the automatic line break in a line (if <wordwrap_mode> = 2)

c) wordwrap_to_linebreak_mode Converts soft line breaks to hard ones when you save in the R/3 System.

0 or false: Soft line breaks are ignored when you save

1 or true: Soft line breaks are converted to hard breaks when you save

The method set_statusbar_mode allows to show or hide the status bar of the control. It has following parameter possible values.

a) statusbar_mode

True: Status bar visible

False: Status bar invisible

The method set_toolbar_mode allows to show or hide the toolbar. It has following parameter possible values.

b) toolbar_mode

True: Toolbar visible

False: Toolbar invisible

Code snippet: -

INITIALIZATION.

sub-prog = sy-repid.

sub-dynnr = 110.

create an object of class c_textedit_control

CREATE OBJECT v_text

EXPORTING repid = sy-repid

dynpro_container = u2018C_CONTAINERu2019

wordwrap_mode = 2

wordwrap_position = 70

wordwrap_to_linebreak_mode = 1.

set the status bar display off

CALL METHOD v_text ->set_statusbar_mode

EXPORTING statusbar_mode = '0'.

set the toolbar display off

CALL METHOD v_text ->set_toolbar_mode

EXPORTING toolbar_mode = '0'.

Step 8 - Code the flow logic of the sub-screen.

Code snippet: -

PROCESS BEFORE OUTPUT.

MODULE PBO.

PROCESS AFTER INPUT.

MODULE PAI.

Step 9 - Code the PBO and PAI modules.

Code snippet: -

****PBO Module.

MODULE PBO OUTPUT.

CALL METHOD v_text ->set_text_as_r3table

EXPORTING table = i_tab.

****Synchronize the front and back ends

CALL METHOD c_textedit_control=>flush

EXCEPTIONS

flush_error = 01.

IF NOT sy-subrc IS INITIAL.

Data transfer error. Your installation is faulty.

MESSAGE a001(cndp).

ENDIF.

ENDMODULE. " PBO OUTPUT

****PAI Module.

MODULE PAI INPUT.

CALL METHOD v_es_1->get_text_as_r3table

IMPORTING table = i_sys_1.

ENDMODULE. " PAI INPUT

Step 10 - Save and activate the program.

Regards,

Joy.

It will work in Module Pool programs. You can upload data from this textbox in the PAI module
