Hello All,

Recently I have been working on a Swipe_Down menu for an application I am TRYING to build for the PB.  At this point I should explain that without the previous support of Zezeke and Jtegen I would probably have less hair than I already do!

Its also worth mentioning, I am NOT a programmer and am embarking on this as the subject matter interests me greatly.

Ok!  I now have zero errors in my application and can build it quite successfully and transfer it to my PB.  But the Swipe Down menu is not working,  I then went into debug and this is the error that I am getting.

VerifyError: Error #1014: Class qnx.pps:PSChannel could not be found.

Simplyput, this would probably be clearer to me if it were written in Zulu!

Please can someone throw some light on how I overcome this and get the menu to appear on the PB?

Many thanks

Bob

It sounds like the qnx-air.swc is being merged into code when linking against the project.This library must be linked externally.

If you are using Flash Builder you can have it do this for you automatically by selecting

Project > Properties > ActionScript Build Packaging > BlackBerry Tablet OS > Include platform specific libraries.

You can also do this manually in Flash Builder by going to

Project > Properties > ActionScript Build Path > Library Path > qnx-air.swc and double click on Link Type and set it to External.

And if you are using the command line you want to use the "external-library-path" switch instead of "library-path"

Hope that helps

Hi Julian,

Thanks for your reply.

I think I may have a further problem as I dont have an option for actionscript build path in the project properties dialogue.

I think maybe I need to add an ANE to the path but then again maybe I am clutching at straws!!

Please advise what you think my next step should be.

Many thanks

Bob

First of all it's zezke Are you sure that's an ActionScript Mobile Project? Because it suppose to look like the screenshot below (Flash Builder 4.6). What version are you using?

Hi Zezke,

I built the project as Flex Mobile project which incorporates the file Menu.as which resides in the utils folder . This is imported from the main MXML file at the line <utils:Menu id="slideMenu"/> (see code below).

In the Project Properties I have included qnx-air.swc in the library build path (see image).

The project compiles and creates a .BAR fie which I can then load to my PB but the swipe_down does not function.  When i run the project on the desktop virtual playbook I get the same errors as I do when I run debug.

Where is your method createMenu called?

[ukracer1]

If I understand your question its in the main MXML under the '//Registers the drop down menu for PB'

protected function createMenu( event:FlexEvent ):void

{

QNXApplication.qnxApplication.addEventListener( QNXApplicationEvent.SWIPE_DOWN, pullDownMenu );

}

private function pullDownMenu( event:QNXApplicationEvent ):void

{

 trace( "Menu pulled down" );

Tweener.addTween(slideMenu, {y: 0, time: 0.5, transition: "linear"});

I don't know MXML, I use pure AS3. You have a method that creates a menu, but that method isn't being called anywhere if I see it correctly.
