Is there a way to implement google maps style zooming in web app ? For desktop app, I use the “mousewheel” event to adjust the scale and offset of a group2D then redraw in the paint event handler of a canvas. Works perfectly. Is there a way to do something similar for web app ?
Yes, but you’d need to be proficient in Javascript to do it properly. If it’s a chart you’re looking to make there are a few third-party charting libraries for Web Edition that may do what you need.
