Creating Design Objects and
Elements 
Creating a Design Object
Firstly, you define the basic layout for your design object. You decide whether to display a single element, a sequence of elements in a row, or elements arranged in multiple rows and columns. You use one of the following classes for this purpose:
Classes for the Layout of Design Objects
Layout |
Class |
Single element |
See Elements Types and Their Classes (except for the element type Label) |
Row-type layout |
CL_SALV_FORM_LAYOUT_FLOW |
Table-type layout |
CL_SALV_FORM_LAYOUT_GRID |
When creating an element of the element type Label, you must always specify the corresponding text element. This means that you cannot use this element as a single element in a design object.
Creating an Element
After you have created a layout for a design object (see above), you can use methods to create elements with the various element types: These methods can be found in the classes CL_SALV_FORM_LAYOUT_FLOW and CL_SALV_FORM_LAYOUT_GRID.
Methods for Creating Elements for a Design Object
Function |
Method |
Create row-type layout (for nested layouts) |
CREATE_FLOW |
Create table-type layout (for nested layouts) |
CREATE_GRID |
Create text element |
CREATE_TEXT |
Create a label for a specific text element |
CREATE_LABEL |
Create a header element |
CREATE_HEADER_INFORMATION |
Create action information |
CREATE_ACTION_INFORMATION |
You use the elements to create objects of the following classes:
Element Types and Their Classes
Element Type |
Class |
Row-type layout (for nested layouts) |
CL_SALV_FORM_LAYOUT_FLOW |
Table-type layout (for nested layouts) |
CL_SALV_FORM_LAYOUT_GRID |
Text element |
CL_SALV_FORM_TEXT |
Label element |
CL_SALV_FORM_LABEL |
Header element |
CL_SALV_FORM_HEADER_INFO |
Action information |
CL_SALV_FORM_ACTION_INFO |
No parameters are required for the row-type layout.
However, for the table-type layout you specify the parameters ROW and COLUMN.
Exception: When creating an element of the element type Label, you must always specify the corresponding text element (R_LABEL_FOR) too, regardless of the layout type.
