Retrieve nodes positions #333

Open fpom opened 2 years ago

fpom commented 2 years ago

How can I retrieve from Python the positions of the nodes in a graph?

When a layout is applied, the field position in .graph.nodes objects is not updated. So far, the only way I've found is to bind a mouseover event on nodes and get the positions from the events, but this is not convenient as it requires specific actions from the user.

I would really like the option to save a layout of the graph after one has re-arranged it to a specific liking.

Is this really not possible?

Even if we get the positions updated from python side, I guess next problem is to set them https://github.com/cytoscape/ipycytoscape/issues/254

I answered #254: I have no problem moving nodes from Python, it requires assigning them positions and then calling the relayout method.

Nice, but still no way to get node positions without mouse over user interaction?

fpom commented 1 year ago

Indeed, I'm still unable to get the nodes' positions, only to set them. So frustrating...
