Adobe AIR Development

[jtegen]

Revision 6 of the community library has been posted to Google Codes at:

http://code.google.com/p/playbook-as3-lib/downloads/list

It has been awhile for an update, but here is a high level list of the changes:

• TextInput fontSize added.
• TimePicker center colons added.
• AirtimeAlertDialog removed (no longer needed).
• Some TabletApplication functions renamed to be more consistent.
• TabletPagedAppBarApplication class added to integrate application bar and pages into one application.
• TabletApplication addLocaleListener added to manage device locale manager correctly.
• Alert code added so items do not get re-added on the draw function.
• Alerts will automatically rotate when the screen orientation changes.
• Slight changes to default alert sizes due to orientation changes.
• Pages will automatically adjust/resize when device orientation changes
• TabletApplication can request an array of services.  This currently allows for AudioManager and Device functionality.

An example AS3 application is also provided that utilizes the library.  It started as a test bed for the library and will be expanded to meet different tests and show examples of how certain things work.  It currently has pages to test alert dialogs and a page to play with the video camera.

jtegen,

 You've been busy! Library is quite different in this version than it was in version 5. Having said that, however, I really like what you've done. It'll take me a while to convert our app over to it, but I like what you've done. Despite taking so long to post, I think I speak for many when I say, "Thank you".

jtegen,

As a suggestion, in the next release a "NextPage" and "PreviousPage" feature would be nice. It'd make it easy to have a unified navigation bar using the TabletPagedAppBarApplication. I've faked it using a check against the current index and total number of indexes. It then either +1 or -1 the index if it's not at either end.

However, setPageIndex keeps returning a "Cannot access a property or method of a null object reference." error.

TypeError: Error #1009: Cannot access a property or method of a null object reference.
	at com.lib.playbook.views::PageViewStack/setPageIndex()[C:\data\flex451\playbook-as3-lib\src\com\lib\playbook\views\PageViewStack.as:135]
	at KitchenSink/nextPage()[C:\Documents and Settings\jpinkerton\Adobe Flash Builder 4.6\Kitchen Sink\src\KitchenSink.as:89]

For reference, the code I'm using to advance an index:

private function nextPage(e:Event):void {
	var i:int = this.page_stack.currentIndex;
	if(i == pvsIndices) {
		trace("End of line.");
	} else {
		trace("Leaving Index: " + i);
		this.page_stack.setPageIndex(i + 1, PageViewStack.RIGHT_LEFT);	
	}
	hideBar();
}

Is there a better method of doing this that I'm not aware of?

Good idea.

Not certain what line 135 is since in my code that is a blank line.  I beleive the index you are passing is out of bounds. I added the following to the library, so you should be able to copy/paste this.  I tested it and it worked fine.

//////////////////////////////////////////////////////////////////////
        public function nextPageIndex( direction : String ) : void
        {
            if( this._current_index + 1 == this._pages.length )
            {
                this.setPageIndex( 0, direction );
            }
            else
            {
                this.setPageIndex( this._current_index + 1, direction );
            }
        }
        
        /////////////////////////////////////////////////////////////////
        public function previousPageIndex( direction : String ) : void
        {
            if( this._current_index - 1 < 0 )
            {
                this.setPageIndex( this._pages.length - 1, direction );
            }
            else
            {
                this.setPageIndex( this._current_index - 1, direction );
            }
        }
