How to unlock node size, and apply force directed layout in Cytoscape app?

[Tib Tony]

Hi,

I am a Cytoscape 3 app developer. After create network and view, I cannot find a place to uncheck the lock node size option to make the node ellipse. In old API there is a NODE_SIZE_LOCKED property but I couldn't find the counterpart in 3. Also, where is the counterpart to apply force directed layout in 3?

Thanks for saving my day!

In Cytoscape 3.1, this should be right on the Style tab (in the Node section). In 3.0.x, you will have to click on Defaults and then the Dependency tab. To change these programmatically, I'd call the getAllVisualPropertyDependencies() method and look for one for which getDisplayName returns "nodeSizeLocked". Then, set that one to true opt false depending on what you want.

As for force-directed layout, it is there - look for "Prefuse Force Directed Layout" on the Layout menu. You can also get it programmatically by calling getLayout("force-directed") from a CyLayoutAlgorithmManager.

Hope this helps...

Thanks Tim!

I am trying the layout programmatically. So I registered the CyLayoutAlgorithmManager clam in Cyctivator and pass it down to the function where I need to apply layout.

getLayout("force-directed") gets the algorithm, but how to "apply" it to the view I generated using addNetworkView? Sorry I am really inexperienced in sorting out java docs.

The visual style has an apply method that accepts a CyNetworkView - that should work, though you may have to call the view's updateView method afterwards...
