Re^2: GUIs in Tk.:Zinc; a perl module experiment

[rocklee]

Appreciate your feedback as always, Sir!

I use the ztkbubble example as a basis for making almost any type of composite item on Zinc.

I think you missed the operative word 'complex', and I failed to explain properly as is tradition by now. Specifically I need to create objects that have one-to-one, one-to-many or many-to-many relationships. Each object has a visual representation on the canvas (filled curve in most cases); Each relationship has a visual representation on the canvas (bezier). I can figure out how to do this -- the question is if some project exists that use Zinc (or canvas) to visualize complex relationships between objects; ie how to best approach this problem in an efficient way using PTK, hopefully saving me hours upon hours of experiments and refactoring ;-)

Subclassing Zinc might be a viable option for me - I will look into this. When I understand bless(). ;-)

Look at Tk::CanvasDirTree where I subclass the Tk::Canvas. You could easily substitute Zinc in that, with minor syntax changes for things like finding the root group and scrollbar control, etc.

You might want to post a new node asking about modules for handling complex interactions, I'm sure I've seen it discussed here before.

Oh great! From browsing it quickly (at work;) it seems to contain quite a few useful pointers. OTOH I am also considering the Zinc C API to do the dirty work - obviously faster, and possibly easier to maintain in the long run.

I guess I'll post a node when I have some more specific questions on this subject.

Thanks again :-)
