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: 

1   const
2     TVS_NOTOOLTIPS = $0080;
3   begin
4     SetWindowLong(yourTreeView.Handle, GWL_STYLE,
5       GetWindowLong(yourTreeView.Handle, GWL_STYLE) xor TVS_NOTOOLTIPS);
6   end;



Solve 2:

7   const
8     {Treeview has no standard way of disabling tooltips}
9     TVS_NOTOOLTIPS = $00000080;
10    TVS_UNDERLINE = $00000200;
11  
12  {Disable the hint window of the treeview, Underline items}
13  SetWindowLong(tvApplications.Handle, GWL_STYLE, GetWindowLong(tvApplications.Handle,
14    GWL_STYLE) or TVS_NOTOOLTIPS or TVS_UNDERLINE);
