The provided class ZCL_UITOOLS can be used via inheritance or as an instance.
Instead of using loop at screen., you can now use the following calls to influence on the screen behaviour. The following examples are based on a class that inheritates from ZCL_UITOOLS
" hide a field by group or name
group( 'GR1' )->hide( ).
field( 'MATNR' )->hide( ).
" hide a selection or a parameter of a report screen
selection( 'S_MATNR' )->hide( ).
" set fields to no-input
group( 'GR1' )->set_noinput( ).
field( 'MATNR' )->set_noinput( ).
" make a field obligatory
group( 'GR1' )->set_required( ).
field( 'MATNR' )->set_required( ).
Using the field( ) method, you can set dropdown values for a list box
field( 'GROUPNR' )->set_dropdown_values(
value #(
( key = '1' text = 'First group' )
( key = '2' text = 'Second group' )
( key = '3' text = 'Third group' )
( key = '4' text = 'Forth group' ) ) ).
The methods ask( ) and ask_with_cancel( ) provide a simple interface to POPUP_TO_CONFIRM
if ask( question = 'Is this OK?' ).
message 'OK' type 'I'.
else.
message 'not OK' type 'I'.
endif.
" verson that displays also a cancel button
try.
if ask_with_cancel( question = 'Is this OK?' ).
message 'OK' type 'I'.
else.
message 'not OK' type 'I'.
endif.
catch zcx_uitools_user_cancelled into data(e).
message e type 'I' display like 'E'.
endtry.
Both methods provide also an optional parameter LONGTEXT where you can pass a longtext object created with SE61
