Question

I’m trying to disable mouse wheel scrolling on the Imageflow gallery plugin (http://imageflow.finnrudolph.de/)
I’ve tried commenting out sections that relate to mousewheel; but it seems to affect the autoscroll option. Any helped would be much appreciated.
Here’ the code:
var my = this;

/* Initiate ImageFlow */
this.init = function (options)
{
    /* Evaluate options */
    for(var name in my.defaults) 
    {
        this[name] = (options !== undefined && options[name] !== undefined) ? options[name] : my.defaults[name];
    }

    /* Try to get ImageFlow div element */
    var ImageFlowDiv = document.getElementById(my.ImageFlowID);
    if(ImageFlowDiv)
    {
        /* Set it global within the ImageFlow scope */
        ImageFlowDiv.style.visibility = 'visible';
        this.ImageFlowDiv = ImageFlowDiv;

        /* Try to create XHTML structure */
        if(this.createStructure())
        {
            this.imagesDiv = document.getElementById(my.ImageFlowID+'_images');
            this.captionDiv = document.getElementById(my.ImageFlowID+'_caption');
            this.navigationDiv = document.getElementById(my.ImageFlowID+'_navigation');
            this.scrollbarDiv = document.getElementById(my.ImageFlowID+'_scrollbar');
            this.sliderDiv = document.getElementById(my.ImageFlowID+'_slider');
            this.buttonNextDiv = document.getElementById(my.ImageFlowID+'_next');
            this.buttonPreviousDiv = document.getElementById(my.ImageFlowID+'_previous');
            this.buttonSlideshow = document.getElementById(my.ImageFlowID+'_slideshow');

            this.indexArray = [];
            this.current = 0;
            this.imageID = 0;
            this.target = 0;
            this.memTarget = 0;
            this.firstRefresh = true;
            this.firstCheck = true;
            this.busy = false;

            /* Set height of the ImageFlow container and center the loading bar */
            var width = this.ImageFlowDiv.offsetWidth;
            var height = Math.round(width / my.aspectRatio);
            document.getElementById(my.ImageFlowID+'_loading_txt').style.paddingTop = ((height * 0.5) -22) + 'px';
            ImageFlowDiv.style.height = height + 'px';

            /* Init loading progress */
            this.loadingProgress();
        }
    }
};

Answer 1

I had the same problem. But of an unmodified version 1.3.0 I edit line 313 which contains:

my.MouseWheel.init();

Just comment it out.

Now I had it auto scroll too, but when you click the div or image, it stops, so I disabled line 819 using a comment.

my.Slideshow.stop();
