There are a number of bugs in the updating processes of TListView and TTreeview.
If I remember correctly a Begin endUpdate wrapping up the .SubItems changes
helped matters both in performance and presentation. There is no solution for the
invisible root-item bug in the Treeview though (I'll find the code example that causes
it so that someone with D5 can check the behaviour)...
We have considerable code handling report layout multicolumn ListViews that perform
the following sequence of instructions successfully...
LV.Items.BeginUpdate;
LV.Items.Clear;
with LV.Items.Add do begin
Caption := 'Spam';
with SubItems do begin
BeginUpdate;
Add('Spam2');
Add('Spam3');
Add('Spam4');
Add('Spam5');
EndUpdate;
end;
end;
LV.Items.EndUpdate;
I believe there are display issues if the Clear is not called in the above for
Listviews with existing items...
