OO syntax problem

[Former Member]

Hi everyone,

from an object of the class cl_salv_table I got another object of type cl_salv_columns_table, let's name it as lo_columns.

In debug mode, when I double click this object I find in the attributes column other classes.

My question is, how do I access to those attributes from other classes?

My example:

for lo_columns object I have

CL_SALV_COLUMNS_LIST and I need the private attribute CELL_TYPE_COLUMN.

There is no method in cl_salv_columns that returns an object of this kind.

Could you help me please?

Best regards,

in your event handler

• Create the Grid object and then access methods within sub / superclasses of the cl_salv_table class.

sorry Jimbo, couldn't get your point.

What's the type of vr_list? CL_SALV_COLUMN_LIST?

I want to set a column as a checkbox... Maybe I'm understanding this all wrong #-/

Thanks a lot,

Hi your original question wasn't clear.

However to get a selection box on this type of grid look at SAP program

SALV_DEMO_TABLE_SELECTIONS.

Note in the SALV functions you don't have any editing capability although you do have event handling. You can only put your cursor on the selection boxes - single, block or multiple selections allowed.

Tthere's no INPUT capability to put an X in the box etc. however.

If you need to CHANGE data via user input to the grid you'll have to use the class cl_gui_alv_grid instead which is a bit more complex.

Cheers
