Because we are not to deal with a whole new set of files which
may go unmanageable in the long run.
Also we agreed that this mechanism will be usedonly where we have
problem with the destruction mecanism.

Local aItems := {}
for i:= 1 to len(aL)
aAdd( oGridItem0x0 , "" )
t := QTableWidgetItem():new()
t:setBackground( oBrushBackItem0x0 )
t:setForeground( oBrushForeItem0x0 )
t:setText( "cella "+str(i) )
oGrid:setItem( i-1, 0, t )
aadd( aItems, t )
next
// And destructor
for each aItm in aItems
qItm := NIL
next
This mechanism has an advantage.
You have all the control over items spread in different columns,
and can later deal with them if there is a need of changes, for example,
if you would like to let it be edited or changing the colors.
This is how it looks close to Clipper syntax.
