Hi

Is there something like the SpaceTreeExpandCollapseManager in the current GEF4 Version?
I was searching for this function but i haven't found anything.

Thank you and best regards

This functionality does not belong to the layout, which is why we have removed it from there. There is a HidingModel, HidingPolicy, and respective *HidingBehavior (with a related HiddenNeighborsFeedbackPart ) implementations, which realize comparable functionality. In contrast to Zest2, the hiding functionality is now generic, it is not bound to SpaceTreeLayout. You would have to adjust that yourself.

Thank you for reply.

A other question. When i open a graph with the SpaceTreeLayoutAlgorithm and my root has some more children, only the root was correctly draw. The children were draw in the left upper corner.
Did is something wrong or is the algorithm not suitable for this case.

Hi Julia,

would you open a separate thread for the issue and provide some more information, please? GEF provides a SpaceTreeLayoutExample where a small tree is displayed, which works fine for me.

Best regards,
Matthias
