SYMPTOMS
========
When a node of a Treeview control is scrolled out of view, the Visible property
of the node is still True.

=====
The Visible property of the node indicates that the node is open and visible as
part of the tree. It does not indicate if it is viewable in the viewport.
STATUS
======
This behavior is by design.

Steps to Reproduce Behavior
---------------------------
1. Create a new Standard EXE project in Visual Basic. Form1 is created by
default.
2. Select Components from the Project menu. Check the box for "Windows Common
Controls," and click OK.
3. Add a Treeview control to Form1.
4. Double-click on Form1 to bring up the code window and add the following code
to Form1:
Option Explicit
Private Sub Form_Load()
TreeView1.Width = 2200 ' so that node 4 is unseen
TreeView1.Indentation = 750
TreeView1.Nodes.Add , , , "Node1"
TreeView1.Nodes.Add 1, tvwChild, , "Node1-1"
TreeView1.Nodes.Add 2, tvwChild, , "Node1-1-1"
TreeView1.Nodes.Add 3, tvwChild, , "Node1-1-1-1"
TreeView1.Nodes(1).Expanded = True
TreeView1.Nodes(2).Expanded = True
TreeView1.Nodes(3).Expanded = True
DoEvents
Debug.Print TreeView1.Nodes(4).Visible
End Sub
5. Run the project. Note that Node 4's Visible property is True even though the
node is not visible through the viewport.
