SAP Design Object Settings in SAP Netweaver Managing ALV Output Areas

You can make settings for a design object, each contained element, and, in the case of a table-type layout, for the individual columns.

Design Object Settings

You can make the following settings for a design object and for design object elements:

Settings for Row-Type Layout (CL_SALV_FORM_LAYOUT_FLOW)

Function	Method
Move element within the layout	SET_ELEMENT
Get number of elements in row-type layout	GET_ELEMENT_COUNT
Set tooltip for design object	SET_TOOLTIP
Get tooltip for design object	GET_TOOLTIP

Settings for Table-Type Layout (CL_SALV_FORM_LAYOUT_GRID)

Function	Method
Move element within the layout	SET_ELEMENT
Append empty row (FLOW object)	ADD_ROW
Get number of rows	GET_ROW_COUNT
Show lines between columns and rows	SET_GRID_LINES
Set tooltip for design object	SET_TOOLTIP
Get tooltip for design object	GET_TOOLTIP

Settings for Elements

You have quite similar functions available for the different element types:

Settings for Element Types

Function	Method	Class
Set wording for element	SET_TEXT	CL_SALV_FORM_TEXT CL_SALV_FORM_LABEL CL_SALV_FORM_HEADER_INFO CL_SALV_FORM_ACTION_INFO
Get wording for element	GET_TEXT
Set tooltip for element	SET_TOOLTIP
Get tooltip for element	GET_TOOLTIP
Set corresponding text element	SET_LABEL_FOR	CL_SALV_FORM_LABEL
Get corresponding text element	GET_LABEL_FOR

Width and Alignment in a Column

A column in the table-type layout of your design object is an object of the class CL_SALV_FORM_GRID_COLUMN. Whenever you create an element in your layout and enter a column that does not yet exist (for example, COLUMN = 2), one or more objects of this class are generated as appropriate. You can use the class CL_SALV_FORM_LAYOUT_GRID to create several column objects in one go.

Methods for a Column in a Table-Type Layout

Function	Method
Get column	GET_COLUMN
Create columns in table layout	SET_COLUMN_COUNT
Get number of columns in table layout	GET_COLUMN_COUNT

You can use the column object to define the width of the column and the alignment of elements in the column.

Methods for Width and Alignment

Function	Method
Set width of column	SET_WIDTH
Get width of column	GET_WIDTH
Set horizontal alignment of elements	SET_H_ALIGN
Get horizontal alignment of elements	GET_H_ALIGN

Width and Alignment of a Single Element

You can define the width and alignment of elements individually. For technical reasons, you must determine whether the element is in a row-type or table-type layout:

· For a row-type layout, use the class CL_SALV_FORM_LAYOUT_DATA_FLOW

· For a table-type layout, use the class CL_SALV_FORM_LAYOUT_DATA_GRID

To change the layout data, first cast the element to one of these classes.

Methods for Layout Data of an Element

Function	Method
Get layout data on the alignment and width of the element	GET_LAYOUT_DATA

To define the width and alignment of the element, now use the methods of the casted classes:

Methods for the Width and Alignment of an Element

Function	Method
Set width	SET_WIDTH
Get width	GET_WIDTH
Set horizontal alignment	SET_H_ALIGN
Get horizontal alignment	GET_H_ALIGN
