Question

Is there a way to update my website with a google map feature that allows mousewheel events for panning instead of zooming?

I am currently working on a unique project that involves creating a mashup with Google Maps (v3) to display real-time GPS data of Boston's buses. While Google typically uses scrolling for zooming in the maps, I believe using panning would be more practical, especially considering that many computers, particularly Macs, now have two-finger scrolling capabilities for both horizontal and vertical movements. My challenge lies in finding a way to access scroll events in order to trigger panning. I came across the mousewheel jQuery plugin, but it seems to only detect vertical scrolling easily. According to Mozilla, Firefox version 3.5 onwards assigns an "axis" property to scroll events, but I have yet to find similar support for other browsers. Could this feature simply be too new to receive widespread compatibility among different web browsers?

This piece of code has been utilized in the past to detect mouse wheel events. It functions well with IE6+ and FF1.0+, although it hasn't been tested with the most recent browsers.

/** A high-level function that reacts to delta being more or less than zero.
 */
function handle(delta) {
        if (delta < 0)
        …;
        else
        …;
}

/** Event handler for mouse wheel event.
 */
function wheel(event){
        var delta = 0;
        if (!event) /* For IE. */
                event = window.event;
        if (event.wheelDelta) { /* IE/Opera. */
                delta = event.wheelDelta/120;
        } else if (event.detail) { /** Mozilla case. */
                /** In Mozilla, the sign of delta differs from IE's.
                 * Also, delta is a multiple of 3.
                 */
                delta = -event.detail/3;
        }
        /** If delta is not zero, handle it.
         * Essentially, delta is now positive if the wheel was scrolled up,
         * and negative if the wheel was scrolled down.
         */
        if (delta)
                handle(delta);
        /** Prevent default actions caused by the mouse wheel.
         * It may not look good, but we manage scrolls somehow,
         * so don't worry too much about it here.
         */
        if (event.preventDefault)
                event.preventDefault();
    event.returnValue = false;
}

/** Initialization code.
 * Modify it accordingly if you have your own event management system.
 */
if (window.addEventListener)
        /** DOMMouseScroll is for Mozilla.
         */
        window.addEventListener('DOMMouseScroll', wheel, false);
/** IE/Opera. */
window.onmousewheel = document.onmousewheel = wheel;
