OO syntax problem

Former Member — Wed, 25 Jul 2007 10:06:42 GMT

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,

André Costa

in your event handler

----

CLASS LCL_HANDLE_EVENTS DEFINITION.

This returns row and column when a cell is double clicked
Other events are available but we only want this one in this application.

PUBLIC SECTION.

METHODS:

ON_DOUBLE_CLICK FOR EVENT DOUBLE_CLICK OF CL_SALV_EVENTS_TABLE

IMPORTING ROW COLUMN.

ENDCLASS. "lcl_handle_events DEFINITION

----

CLASS lcl_handle_events IMPLEMENTATION

----

CLASS LCL_HANDLE_EVENTS IMPLEMENTATION.

On Double click display factuur, Proforma, or Order (not batch)

METHOD ON_DOUBLE_CLICK.

PERFORM DISPLAY_DOCUMENT USING ROW COLUMN.

ENDMETHOD. "on_double_click

ENDCLASS. "lcl_handle_events IMPLEMENTATION

Create the Grid object and then access methods within sub / superclasses of the cl_salv_table class.
The Object instance is returned in variable gr_table. This is then used as the Instance reference
for accessing attributes and calling methods within the cl_salv_table class.

TRY.

CALL METHOD CL_SALV_TABLE=>FACTORY

EXPORTING

LIST_DISPLAY = GR_LISTORALV "ALV or classic list

IMPORTING

R_SALV_TABLE = GR_TABLE "ALV object instantiated

CHANGING

T_TABLE = TA_LIST. "Data table display (internal table)

CATCH CX_SALV_MSG. "If error in Object Instantiation

ENDTRY.

Set Grid Layout options

GR_FUNC = GR_TABLE->GET_FUNCTIONS( ). "Enable Grid standard functions (and user if they exist)

GR_FUNC->SET_ALL( ABAP_TRUE ). "Show and enable standard Toolbar. (ALV)

GR_DISPLAY = GR_TABLE->GET_DISPLAY_SETTINGS( ). "Enable limited programmable layout setting changes

GR_DISPLAY->SET_HORIZONTAL_LINES( VALUE = ' ' ). "Switch off Horizontal lines

GR_DISPLAY->SET_VERTICAL_LINES( VALUE = ' ' ). "Switch off Vertical lines

GR_TABLE->DISPLAY( ).

----

FORM DISPLAY_DOCUMENT USING I_ROW TYPE I

I_COLUMN TYPE LVC_FNAME.

READ TABLE TA_LIST INDEX I_ROW INTO VR_LIST.

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,

André Costa

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
