Supporting Blackberry Webworks trackball/mouse

**pagameba** · 4 Nov 2011 1:24 PM

In trying to get TabBar buttons working with a blackberry trackball/mouse in a webworks packaged application, I've discovered that Blackberry supports an x-blackberry-focusable="true" (or false) attribute on elements which enables them to be focusable by scrolling the trackball. This doesn't actually make it work, though. It also needs to support a 'click' event which I have faked by creating my own Ext.Button subclass and adding a click handler since the Ext.Button init method only tacks on tap events. This only works on buttons that I specifically create with my own xtype, I'm not sure how to get it to work with the automatically generated back button in a NestedList (for instance). Which also brings up the point that items in a list/nested list are not clickable either.

Are there any quick work-arounds that would enable both tap and click events to be registered everywhere? Is this something that could make it into the next release?

Problem is we don't support non-touch blackberry devices.

I realize that

What I am suggesting is that it is theoretically it shouldn't be too hard to support non-touch events since the framework does already support them for browsers and, if you add a handler for click as well as touch it will actually work. What I could not discover (and I wasn't sure if I should be hacking around in the core) is how to generically enable routing touch and click events to the same handlers when running on a mobile device. I believe this is worth doing as all blackberry phones seem to include the trackball and users seem trained to use it.

Cheers

Sorry for self-plug but see my blogpost. This was for ST1.1, I haven't tried it on ST2

Interesting ... hopefully I can get to try this out shortly and report back here. It would be great if Sencha would add this to the main code base!

Yup, if you see my other post I show how to set up a listener on scrolling with the ball since you can't touch and scroll on some BB OS6 devices. (make sure to check comments, some have their own implementations that may/may not be better)

Hi, I'm trying to start working with st2 for blackberry. I'm using a bold 9780 with os6 I have not tested yet your proposal to scrolling using the trackball but I want to incorporate it to my application. Before it, I have an issue I need to solve:

I have an application that works (more o less) in the emulator but in a phisical device doesn't render anything.

Doing some testing I've discovered that the sencha-touch-all-debug.js is not fully loaded. Seems stop loading at any moment and only what I get is a blank screen.

Since this only occur in the phisical device I have not so much alternatives to inspect where the problem is.

Here you have the details of the device:

Blackberry 9780 (3G, Wifi)
6.0 Bundle 2391 (v6.0.0.534, , platform 6.6.0.200)
I ve tested the st2-pr3 and the st2-gpl final release with same results

This is the application I'm testing:

HTML Code:

<!DOCTYPE html>
<html>
   <head>    
        <meta charset="utf-8">    
        <script type="text/javascript" src="sencha-touch-all-debug.js"></script>
    </head>
    <body>
          <script type="text/javascript">
            Ext.setup({
                 onReady: function() {        
                       alert('start');    
                 }
            });
           </script>
       </body>
</html>

Please, could you tell me what devices have you tested, and if you know how can I debuggin from a phisical device?

FidoX, sencha-touch-all-debug.js is pretty big, try the non-debug version sencha-touch-all.js

Also, I've found Sencha Touch 2 too slow for BB6 so I've had to bump the min requirements to BB7....
