    Default Answered: pre/post callback between each carousel transition

    Answered: pre/post callback between each carousel transition


    Hi,

    I have a carousel and i wanna know if it is possible to launch an action when i leave a one item and another action when switch to.

    In other words, can i define callbacks (pre and post) called between item transition.

    Indeed, i wanna start and/or stop some points before or after a transition.

    I join a diagram that explain the state diagram i want to use.

    Thanks in advance for your reply.

    Regards

  2. You can use the activeitemchange event with the before and after order option.

    Thanks, it works fine as expected using the following code :

    Code:
            horizontalCarousel.on("activeitemchange", function(me, value, oldValue, index)
            {
                console.log(horizontalview[this.getActiveIndex()] + '-' + this.getActiveIndex());
            });
    And my whole code :

    Code:
    var Myapp = Ext.application(
    {
        name:   'Myapp',
        launch: function()
        {
            var horizontalCarousel;
            var verticalCarousels = [];
            var items, i, j;
                
            /* ------------------------------------------------ */
            /*                 Vertical items                   */
            /* ------------------------------------------------ */
            //alert("nbHorizontalItems="+nbMaxMainScreen);
            for ( i=0 ; i<nbMaxMainScreen ; i++ )
            {
                items = [];
                    
                /* ------------------------------------------------ */
                /*              Horizontal items                    */
                /* ------------------------------------------------ */
                //alert("nbVerticalItems="+nbMaxSubScreenPerMainScreen[i]);
                for ( j=0 ; j<nbMaxSubScreenPerMainScreen[i] ; j++ )
                {
                    //alert("i="+i+"/j="+j);
                    //alert("content["+i+"]["+j+"]="+mainScreen[i][j]);
                    items.push(
                    {
                        html : mainScreen[i][j],
                        style: 'background-color: #FFFFFF'
                    });
                }

                /*             Fill vertical's carousel             */

                verticalCarousels.push(
