Item only show partial text in List View
2
I am using Delphi XE3. In a form, I add a TListView and set its ViewStyle to vsList. Then I try to add an item with a long text to the list view, as follows:
procedure TForm1.Button1Click(Sender: TObject);
var
ListItem: TListItem;
begin
ListItem := ListView1.Items.Add;
ListItem.Caption := 'A very very long text long text long text long text long text';
end;
However, the added item will only show partial text, as below:
How to solve the problem?

@TomBrunberg Don't think so, perfectly possible for the full text to be display in list view style

BeginUpdate/EndUpdate recalculates columns widths (but why this is not done during adding?) and calls WM_SETREDRAW (perhaps adding redraws only rectangle with "old" item size)
var
ListItem: TListItem;
begin
ListView1.Items.BeginUpdate;
try
ListItem := ListView1.Items.Add;
ListItem.Caption := 'A very very long text long text long text long text long text';
finally
ListView1.Items.EndUpdate;
end;
end;

- .. recalculates columns widths .. " - Only those that exist. I mean you don't have to have any columns in vsList mode. What matters is theWM_SETREDRAWcalls, seems to trigger some sort of internal layout calculation.

I think the using of BeginUpdate/EndUpdate will improve the performance when updating a large volume of items. That is the reason why Delphi does not update when each item is changed.
