Adding Finger Scrolling To Your RhoElements App
You may have read a feature which allows you to do some pretty amazing things, but in this post I will be showing you how to get some simple finger gesturing into you application where you may require scrolling. Right now, the current RhoElements version does not support native finger scrolling if your HTML content is larger then what can be displayed. This means that if you enabled scrollbars in the config.xml you would see those ugly old Windows Mobile scroll bars and you would have to click on them in order to scroll.
These are not very finger friendly, and quite honestly don't behave the way we all have grown accustomed to on on mobile phones. Before I get into how to do this, I want to thank who is in our Motorola Education team for providing the code behind this.He developed a clever way to use the jQuery framework + basic CSS to enable content to be scrollable by simply giving it a "scrollable' class. There may be many other ways to do this and I would urge you to comment if there are other methods you have found, but this seems to be a way that most people can incorporate without much effort. The code behind this uses the jQuery library which is now possible because of RhoElements support for webkit and HTML5. Now jQuery has been around for a while and there are like hundreds of plug-ins for it. This sample does not use any special jQuery plugins (if anyone finds one that works better/easier than this please post a comment). I am not going to walk through jQuery itself here, there are already a ton of postings like that on the web, but really the only thing we are using it for in this example is to easily traverse the HTML tags, assign functions to mouse events and to move the content on the display.
Lets take a look at the html page:

It didn't work for me although it worked on Chrome locally. Sliding is very frustrating in rhoelements
here's a plugin that does the trick, turns any div into scroll-able item...

good documentation too.
