drag and drop (orders into a tour)

This forum deals with any kind of web based client technology, whether it is the well known java script based Ajax servlet or the upcoming approaches such as Leaflet, OpenLayers and so on.

drag and drop (orders into a tour)

Post by danper »

Hello everyone,
I'm trying to help a custumer doing interactive stuff with ajaxmaps and I would share with you my considerations. The feature is to drag some points (orders or clients) on the map and drop them in an already drawn tour (polyline).
Obviously the business logic will check whether the orders are compatible with the selected tour and so on, my effort, at the moment, is to provide a method that intercepts the second click (drop) and establish the nearest tour (within a tollerance). Having the n-points and the tour will be easy to code a method that puts the orders inside the tour, if it is feasible. Do you have any suggestion about this? It would be nice to have a look to some code if you even had done it.
Thanks to all!
Dan

Hello Daniele,

I'll forward your request to some developers... as far as I know them they'll answer quick.

Best regards Bernd

Hi Daniele,

here's a tutorial sample for creating selectable and draggable elements that can be dropped on each other (including lines). It consists of a custom marker class (for selectable and draggable icons), a custom line class (for selectable lines that can serve as drop targets) and a VectorLayer subclass to handle drag-and-drop events.

Regards,

Andreas
