[Solved] Force position of vertical scrollbar ?
Posted: Thu Nov 22, 2007 1:58 pm
Is it possible to force the position of the vertical scrollbar ? Sometimes i must build again all my treeview, and i would like to show the treeview at the same position as before it has been rebuilt.

To solve this problem, I would need a function like TTreeNode.MakeVisible() which doesn't exist in TeeTree (as TTreeNodeShape don't inherit from TTreeNode).
Still no support about this problem ?

You can move the scrollbars to a position with the VertOffset and/or HorizOffset of the View3DOptions.
So before rebuilding, you could store these values in temporary variables. After rebuild, you assign them back to VertOffset and HorizOffset.
Code: Select all
procedure TForm2.btnRebuildClick(Sender: TObject);
var tmpH, tmpV: Integer;
tmpH := Tree1.View3DOptions.HorizOffset;
tmpV := Tree1.View3DOptions.VertOffset;
Tree1.View3DOptions.HorizOffset := 0; //Simulate rebuild
Tree1.View3DOptions.VertOffset := 0;
Tree1.View3DOptions.HorizOffset := tmpH;
Tree1.View3DOptions.VertOffset := tmpV;

Thanks for the answer, it works well. User just sees the scrollbar "blinking" because it jumps to the position 0 and then to VertOffset, but it is still far less annoying than before.
