But not much about TListBox.
It simply needs a scrollable list of custom drawn rects with click,
double click, selected item, ensure selected is visible, begin update,
end update. TStringGrid can do that.
Can TStringGrid handle 30.000 rows?
Because this is easily created by compiling with -vt and TListBox can
not handle it fast enough.
