is how to handle all the Drag/Drop logic with the
Icons,
Sounds interesting. :) I would make a component, MapViewer extends UIComponent. Composite 2 components into this component. - MapLoader extends SWFLoader - MapAssets extends Canvas MapViewer will be the control into positioning the icons as your drop them INTO the MapAssets aka the map assets instance is position 0,0 with the MapLoader right on top. MapView sizes and positions the MapLoader and MapAssrts instances. Once you have this base set up, set your tool bar - drag off the tool bar, create a dragData object with a new instance of the said icon, - user drops icon onto MapViewer - MapViewer konws how to accept dragDrop, then processes the x,y position converts coords, takes that new instance you created from the tool bar factory and addChild() into the MapAssets component precisely where the user dropped it. Now that the icon is perfectly placed INSIDE the MapAssets instance as the user pans the map around, them icon follows because the MapViewer is positioning the MapLoader along with the MapViewer. May or may not make sense but from what you described I could easily get that scenario going. Peace, Mike On 2/3/07, lostinrecursion <[EMAIL PROTECTED]> wrote:
I agree. AS3 actually has the most incredible drag and drop support and it is also very easy to implement via Flex. In fact, all List based components have this functionality native to them. But adding it to a non list base component isn't awfully hard either. Look in the docs for drag and drop and look for "Image to a Canvas" examples on drag/drop - I believe that ought to answer many of your questions. Good luck with the app. Sounds heavy. -Kenny
