Nodes have a .Expand() method, which executes whenever the node is expanded,
either by clicking on plus sign or clicking on icon. You may use a custom
method that expands and collapse nodes, called from both Node.Click and
Node.Expand, after checking if the node is already expanded (otherwise
Node.Click will call the method, then the Node.Expand event will occur,
doing the things twice). You may also check if the node to be expanded is
the selected node (Nodes(node.Key).Selected = .T.), otherwise
expanding/collapsing nodes programatically will trigger the whole process
over and over again.
I don't have a list of differences, but the most important one is SP4
version does not support themes. :(

Hi Grigore
Must be the SP2 version as I cannot see a SingleSel property.
Your suggestion works if you click on the Icon but not if you click on
the plus sign. This may work better as it gives the operator the choice
of either method. But it would be nice to know how to make it work
clicking on the plus sign
Incidentally do you know if there are any differences in the two
controls, would it be easy just to use the other control and transpose
the PEM's
Cheers
Peter

Hi, Peter
If you are using the SP2 one, you can scan the nodes and collapse each
one,
except the one clicked.
In NodeClick Event:
lParameters node
For lnI = 1 To This.Nodes.Count
This.Nodes(lnI).Expanded = .F.
EndFor
This.Nodes(node.Key).Expanded = .T.

Thanks Grigore
By the way congratulations on your MVP Status.
Still waiting to hear about Prague as to whether it will be worth
attending. I would like to go as I enjoyed meeting you and the rest of
the Crowd.
Cheers
Peter

Hi.
Set the treeview.SingleSel property to .T. VFP comes with two treeviews:
Microsoft TreeView Control 6.0 (SP 4) and Microsoft TreeView Control,
version 5.0 (SP 2). Only the SP4 one has this property.
Hope this helps.
Grigore Dolghin.

Hi All
You may have seen previous questions of mine about TreeView Controls.
Some of my applications use a the Microsoft TreeView Control as a Menu
at the side of the application Screen.
The Nodes expand fron the top of the tree to emulate a VFP Menu at the
first Left and then each node can be expanded to display the pads of the
menu. When the application is closed the current state of the TreeView
is saved so that the Treeview opens when the Application is opened in
the same state it was. This has worked fine but. Some of the
applications have so many pads open that they extend below the bottom of
the screen.
I wonder if anyone has any idea how I could make each (First) node
Collapse as another is clicked to Expand it. I.E. I have Four Menu Pads
System, File, Windows, Help. I click on File and it expands. I click on
Window and it expands and File collapses.
TIA
Peter
