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_splitter_container
o cl_gui_container
o cl_gui_dialogbox_container
4. Display table and show details.
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_splitter_container
o cl_gui_container
o cl_gui_dialogbox_container
o cl_alv_event_toolbar_set (in event handler)
5. Display table and show details.
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_splitter_container
o cl_gui_container
o cl_gui_dialogbox_container
o cl_alv_event_toolbar_set (in event handler)o cl_ctmenu (in event handler)
