Tree View, horizontal scroll problem

I have a problem with the TreeView horizontal scrolling.

When I set the TopItem propertie and the tree node text's lenght is
greater than the TreeView's Width, Delphi scroll horizontally the tree
so it can show more of the tree node's text in the Tree View.

I need that the tree never scroll automatically horizontally.

Is there a way to stop this ?

I need to scroll horizontally but manually with the mouse !
