The "delay" I talked means there is distance between the cursor and the last point of stroke when drawing a long line quickly. As we know the whole stroke was redrawed on every point added, the amount of points may cause the delay. I am sure this not happened in my example.

I managed to see a noticeable delay after showing the alignment grid. If you are using the grid, you might try hiding it when drawing free lines.

Thanks

Another question:
I notice that during creating a node in the diagram, first I need to click at a point ,then move the mouse to size the node.

I need to create a node within the diagram by click once. (Add a point ) But when I click the mouse, I found only StartCreate() method was called. So there is nothing created in the diagram.

You can create it from the Diagram.Clicked event handler. E.g. this code creates a node centered at the clicked point:

Code
Select All
private void OnDiagramClicked(object sender, DiagramEventArgs e)
{
	if (e.MouseButton == MouseButton.Left)
	{
		var rect = new Rect(e.MousePosition, new Size(0, 0));
		rect.Inflate(40, 30);
		diagram.Factory.CreateShapeNode(rect);
	}
}


I hope that helps,
Stoyan
