Hi,

There is a function FlowChart.getBoxes() which gets all the boxes on the flowchart. Now, in very interactive diagramming, where we write logic on mouse moves/drags using this function turns into a lot of processing, especially if there are like 1000 boxes spread over the canvas.

Can a similar function be provided where the search scope could be reduced to a specified rectangle so that we deal with fewer objects?

I know there is getNodesAt(Point), I was thinking maybe getNodesIn(Rectangle2D.Float)

Thanks,

Hi Stoyan,

The Rectangle2D.Contains method would return a true or a false.

So, I will have a Rectangle2D object with me. Then I will have to pass each of the box's bounds to that guy to check if the rectangle contains it.

So, I will have to loop through each of these boxes on the flowchart.

I hope I didn't understand your explanation wrong.

I was just wondering having a trimmed down function that was something like Flowchart.getNodesIn(Rectangle 2D.Float)

Thanks,
Praveen

Hi,

That's alright. I was wondering if you'd internally use a more optimized method than searching through all the boxes. If that is how your API would be doing it anyway, I will include that code myself right now.

Thanks,
