[Moose-dev] TreeMapLayout

Hi, I made some progress with the TreeMapLayout. Two challenges remain to be solved. The first one is related to dragging. It is kind if complicated to explain in words, so I made this short screencast: http://cl.ly/150n1t2Z2h1y3L0z1U0L As you can see the positions of the shapes get updated only when hovering over them, not instantly when dragging, as I would like them to. One difference code-wise to other graph layouts is that the owner of all shapes is, in this case, not MORoot but the node "org", which is a normal MONode. I had to do this (change ownership) because MORoot does not get drawn (is this by design?). Does anyone have some ideas on what could explain this behavior? Another question would be: Is it possible to make the inner nodes not draggable? The user should not be able to move individual shapes inside the TreeMap around. Cheers, Dennis
