Re: [Dynapi-Help] Control speed in viewport

[Michael Pemberton]

The slideTo method used by the vlewport has a forth variable called "ms".  This defines how long there is between movements.  You could use this to slow down the speed that the scroll works at.

Here's a tweaked version of the viewport from my own version with the feature included.  The code should be similar to the official version, if you have any probs, feel free to email me.

ViewPort.prototype.scrollUp=function(ms) {this.scrollSlide(null,0,ms);};
ViewPort.prototype.scrollDown=function(ms) {this.scrollSlide(null,-this.availableScrollY);};
ViewPort.prototype.scrollLeft=function(ms) {this.scrollSlide(0,null,ms);};
ViewPort.prototype.scrollRight=function(ms) {this.scrollSlide(-this.availableScrollX,null);};
ViewPort.prototype.scrollSlide = function(x,y,ms) {
    if (x!=null && this.enableHScroll) {
        this.invokeEvent("scrollstart");
        this.contentPane.slideTo(x,this.contentPane.y,null,ms);
    } else if (y!=null && this.enableVScroll) {
        this.invokeEvent("scrollstart");
        this.contentPane.slideTo(this.contentPane.x,y,null,ms);
    };
};

Hello

Thanks for a great API. I wonder if there is any possibility to control the speed when using a viewport for scrolling up and down. In sliteTo you can specify this and it would be great to be able to do it in this funktion to. I think the speed is to fast.

Best Regard Stellan
