CLASS LCL_EVENT_HANDLER

Former Member — Thu, 02 Sep 2010 08:22:04 GMT

Hi,

I have just started to use object oriented and i have a lot of questions in my head. I am trying to do hotspot on alv list for now.I did it with gs_layout-keyhot = 'X' but i have no idea about how i can see information on another screen for each row when i click a row.I think i should use CLASS LCL_EVENT_HANDLER. The big thing is how i can do that.I will be pleased if you can help me about this.

Regards.

Hi,

1. Define your local class (LCL_EVENT_HANDLER.)

Definition:

public section.

methods:

hotspot_click for event hotspot_click

of cl_gui_alv_grid

importing e_row_id

e_column_id

es_row_no.

Implementation:

method hotspot_click.

perform event_hotspot_click using e_row_id

e_column_id.

endmethod. "hotspot_click

2. Mark in fieldcatalog:

ls_fcat-fieldname = 'YOUR_FILED'

ls_fcat-hotspot = 'X' ( or ls_fcat-style = cl_gui_alv_grid=>mc_style_hotspot. )

3. Event object and handler:

in pbo:

create object o_event. (define: type ref to lcl_event_handler)

set handler o_event->hotspot_click

for your_grid.

Regards,

Hi,

refresh_table_display should work fine.

Just code::

- for the first time display

grid->set_table_for_first_display

- for next times (and after having modified the internal table you are displaying)

grid->refresh_table_display
