For opening closing, there is a treeState property of the tree model that stores the expanded/collapsed paths of the tree. These paths are made up of indexes (not node IDs - be careful on this one, it is not documented anywhere) that are zero based.
So the tree (assuming A is the root node) A B C D E Would have expanded 0 (A), 0:0 (A, B), and 0:1 (A, D). The default tree state simple remembers these paths and as it is rendering, looks at these to determine which are expanded and which are collapsed.

Hi Sean I guess I could solve the #5 with checkboxes and an attribute "selected" for every node so it should not be a problem. But I don't know how I can solve #1 to #4. I tried but I didn't work. So is there a example around where I can have a look or a description about this topic.
