Victor Voilevitch

1. Display table .

This tiny program just displays the T001 table using grid control and all its defaultfeatures.

Used object: cl_gui_alv_grid

2. Display table .

Like previous but added print events handling for printing the table contents using grid"Print" button.

Print events:

o print_top_of_list

o print_top_of_page

o print_end_of_page

o

print_end_of_list

Used object:

o cl_gui_alv_grid

o cl_gui_splitter_container

o cl_gui_container

3. Display table and show details.

Like previous but added double click event handling. After double clicking on a table line

detailed information for the line is displayed in another grid.

Events:

o print events (see above)

o double_click

Used object:

o cl_gui_alv_grid


o cl_gui_container

o cl_gui_dialogbox_container


Like previous but added my own button to the grid toolbar. The function is the same as fordouble click.

Events:

o print events (see above)

o double_clicko toolbar

o user_command

Used object:

o cl_gui_alv_grid


o cl_gui_container


o cl_alv_event_toolbar_set (in event handler)


Like previous but changed context menu for the column #2 - added my own function codeand disabled all standard functional codes. Context menus for other columns remainunchanged. The function is the same as for double click or additional button.

Events:

o

print events (see above)o double_click

o toolbar

o user_command

o context_menu_request

Used object:

o cl_gui_alv_grid


o cl_gui_container


o cl_alv_event_toolbar_set (in event handler)o cl_ctmenu (in event handler)
