Coloring Rows 

Purpose

You can color rows in the grid control different colors and in this way highlight data in the list.

Columns can be colored using the field EMPHASIZE of the field catalog (see: Column Output Options).

 

Process Flow

...

       1.      Define the Layout Structure of type LVC_S_LAYO.

       2.      Extend your output table by a four-digit character field as in the following example:

DATA: BEGIN OF GT_OUTTAB OCCURS 0.
        INCLUDE STRUCTURE <DDIC Structure>.

DATA:   linecolor(4) type c.  "Color for corresponding line

DATA: END OF GT_OUTTAB.

       3.      Select your data and copy it into the output table.

       4.      Read one row of the output table at a time in a loop. To change the color of rows, assign the character field a four-digit color code.

You can find more about color coding in the EMPHASIZE field of the field catalog (see Column Output Options).

       5.      Assign the name of the internal table to the field INFO_FNAME of the layout structure (which, in our case, is 'LINECOLOR', see step 2).

       6.      Pass the layout structure and the output table with method set_table_for_first_display.

If you do not want to color cells for the first display, execute step 4 later and refresh the output table with the method refresh_table_display.

 

 

Accessible Color Display

To make colored identifiers of ALV elements accessible to visually-impaired users it is necessary to maintain a tool tip for the color.

For this you have to maintain some fields in the table it_except_qinfo for the interface CL_GUI_ALV_GRID->SET_TABLE_FOR_FIRST_DISPLAY:

 

TYPE	Required	4                (= Color)
FIELDNAME	Optional	Only has to be completed if the meaning of the color in relation to the related values for VALUE and TEXT is only valid in a special column of the ALV.
VALUE	Required	Color of elements.
TEXT	Required	Tooltip text.

 

Table it_except_qinfo is of type slist_t_qinfo_alv.
