I'm creating some kind of drawings/flowchart/UML-diagram like tool with GWT Canvas (Java). For hit-detection of my drawings I could imagine 3 different strategies, but I do not know which would work best for my goal.
- Just keep track of all Shape coordinates and iterate all objects on mouseclick - draw all objects on a ghost-canvas on mouseclick, and use isPointInPath() after every object drawing - using a ghost-canvas and draw each object with its own color (like #000001, #000002), and keep reference of them in a Map<Color, Shape>. Then just detecting the mouseclick on the ghost-canvas and get the object belonging to the pixelcolor under mouse What would you prefer, and why? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
