Selecting a node creates a new node

[ankurankan]

You might have noticed that clicking on a node to select it is creating a new node there. Also I don't think a click for creating a node is a good idea. We should have some other way to create a node. Something like an option on the top of the page labelled "create node" clicking on which will create a new node. That would result in a better user interface. What do you think? @pramttl @gargshashank5 @snigam3112 @abinashpanda

I have noticed that clicking on a node is creating a new node. I also agree with @ankurankan that there should be an option at top labelled "create node".

Yeah correct, so far what we have done here is an experiment (not a final feature) to make sure we can:

• Add node at a desired coordinate
• Map mouse pointer location to a coordinate on the canvas.

Yes, we must have a "Create Node" button as you guys suggest as otherwise it conflicts with "selecting a node" and creates more latent problems that I can already see.

(1) After a user clicks on "Create Node" button a possible idea is to shift states. (A state machine :p)

State Diagram:

Normal-State ------(A1)-----> Create-Node-State

Action:

• (A1): Clicking on "Create Node" button.

States:

• Create-Node-State: is the same as you see now. ie clicking on a location adds a node there.

• Normal-State: In this state clicking should not create new elements like nodes or edges.

  Thoughts?

Yes I think this would be a good interface. Because if we have a simple create button the user will have to click on the button and then move each node after it is created.
