How to disable hints in a TTreeView

Answer:

Solve 1:

If you have installed the Internet Explorer 4.0 or high, in TTreeView component always displaying a hint for cutted items. It's useful but sometimes prevents and irritates (at least, me).

But there is a simple way to switch off this feature:

const
  TVS_NOTOOLTIPS = $0080;
begin
  SetWindowLong(yourTreeView.Handle, GWL_STYLE,
    GetWindowLong(yourTreeView.Handle, GWL_STYLE) xor TVS_NOTOOLTIPS);
end;


Solve 2:

const
  {Treeview has no standard way of disabling tooltips}
  TVS_NOTOOLTIPS = $00000080;
  TVS_UNDERLINE = $00000200;

{Disable the hint window of the treeview, Underline items}
SetWindowLong(tvApplications.Handle, GWL_STYLE, GetWindowLong(tvApplications.Handle,
  GWL_STYLE) or TVS_NOTOOLTIPS or TVS_UNDERLINE);
