Adding new types of Connectors

Hi all,

Any advice on where to start to add new types of Connectors? I'd just like a "Decision" connector ( a diamond shape that I could type some text into) to graphically create some algorithms for a project I am working on.

From there, I want to create different kinds of decision "steps" that would be subclasses of this basic "decision" connector. Then, hopefully, I can "read in" the structure to create a file based on the algorithm that will be the input for my project.

Thanks in advance,

Rob

You mean like the "Text Ellipse" and "Text Rectangle"? Look at NCEllipseMorph, you basically just need to change the drawOn: method.

OTOH you can do this without coding, just take a polygon to make the diamond shape and embed the text in it. For convenience, adjust the layout to keep the text centered, and your done.

Oh...I see...the Connectors package works with any Morph...!

I'll try what you mentioned...thanks!

Hehe. You're beginning to understand what's so powerful about Morphic and Etoys.

Yep. Also look at StarMorphs. They can have 2 points which is a diamond.
Any orientation and any aspect ratio.
