Unconnected nodes in tree

Hi,

I have a tree layout and add a bunch of nodes that I read from a file then connect them.  I would also like to add "unconnected" nodes and have them automatically line up on the bottom or side of the view.  Is there a way to do this?

Thank you,
Joe

Hi Joe,

Try setting TreeLayout.MultipleGraphsPlacement = MinimalArea. If you need more control over the node positions, you could do something like this:

Code
Select All
// add and arrange tree nodes
// ...
treeLayout.Arrange(diagram);

RectangleF r = diagram.GetContentBounds(false, true);
r.Y = r.Bottom + yoffset;

// add the rest of the nodes
// ...
foreach (DiagramNode node in unconnectedNodes)
{
	r.Width = node.Bounds.Width;
	r.Height = node.Bounds.Height;
	node.Bounds = r;
	r.X = node.Bounds.Right + xoffset;
}


I hope that helps,
Stoyan

Hi Stoyan,

Thanks for the tip.  The second way (coding) seems to work a little better as I have more control over things.

Joe
