Rearrange Containers on Fold/Unfold?

Hi,

i have several ContainerNodes, each is a new graph.
The layout places them vertically:
layout.MultipleGraphsPlacement = MultipleGraphsPlacement.Vertical;

When i fold one container i want the diagram to be rearranged so the gap between the now folded container and the next ohne is closed.
And when i unfold the container it has to be rearranged so the distance to the next one is the same again.

layout.Arrange(myDiagram) seems to ignore the fact that a container is folded.

How can i get this done?

thx

Hi,

Indeed the GraphsPlacement function allocates space for container's children even if the container is folded. There is no way to prevent that now. If you only need to arrange all containers vertically, you could directly set their Bounds instead of using Layout.Arrange:

Code
Select All
private void diagram_ContainerFolded(object sender, NodeEventArgs e)
{
	float x = 10, y = 10, p = 5;
	foreach (DiagramNode node in diagram.Nodes)
	{
		if (node is ContainerNode)
		{
			node.Move(x, y);
			y += node.Bounds.Height + p;
		}
	}
}


I hope that helps,
Stoyan
