[AIR] How to hide bar at the bottom of application

damian — Thu, 07 Oct 2010 17:51:10 +0000

Every AIR application has by default a bar at the bottom. It is shown in the picture below:

Status bar

To hide it, you have to add one line for example in application’s applicatonComplete handler:

/**
* Application's applicationComplete handler
*
* @return void
*/
protected function this_APPLICATION_COMPLETE():void {

statusBar.visible = false;

}//function

Drag and drop in AIR appliaction

The following post presents steps that should be taken to enable drag and drop action of files in AIR appliaction.

In order to use drag and drop funcionality we need to implement two functions that will react to nativeDragEnter and nativeDragDrop events.

NativeDragEnter event is dispatched when mouse pointer with dragged content passes boundaries of a component. All we do in this handler is accepting the dragged data. If we don’t do it the plus-sign-icon won’t appear next to the mouse pointer and we won’t be able to drop dragged data. To accept the dragged content we need to use acceptDragDrop(target:InteractiveObject) function from the static NativeDragManager class.

private function nativeDragEnter_handler(event:NativeDragEvent):void {
NativeDragManager.acceptDragDrop(some_interactive_object);
}

If you’d like to to check what kind of data was dragged over component you can use event.clipboard.hasFormat(format:String) function which takes one of the following consts as a parameter:

BITMAP_FORMAT: a BitmapData object,
FILE_LIST_FORMAT: an array of File objects,
HTML_FORMAT: HTML-formatted string data,
RICH_TEXT_FORMAT: a ByteArray containing Rich Text Format data,
TEXT_FORMAT: string data,
URL_FORMAT: a URL string.

It returns TRUE if the dragged data is compatibile with the specified format.

NativeDragDrop event is dispatched when user releases the dragged item over the component. In this handler we will use event.clipboard.getData(format:String) function to get the dragged data. If the dragged items were some files from a hard drive then the specified format would be FILE_LIST_FORMAT.

private function nativeDragDrop_handler(event:NativeDragEvent):void {
var files:Array = event.clipboard.getData(ClipboardFormats.FILE_LIST_FORMAT) as Array;
}

Updating AIR application with ApplicationUpdaterUI

The following post shows how to use ApplicationUpdaterUI class to update AIR application.

How to use ApplicationUpdaterUI?

How to use ApplicationUpdaterUI?

AppliacationUpdaterUI may need to restart the application therefore it is good to check for updates during application startup.

applicationUpdaterUI = new ApplicationUpdaterUI();
applicationUpdaterUI.updateURL = "URL to your XML udpate descriptor";
applicationUpdaterUI.addEventListener(UpdateEvent.INITIALIZED, applicationUpdaterUI_INITIALIZED);
applicationUpdaterUI.initialize();

Once application updater is initialized we can start the update process with checkNow() method.

private function applicationUpdaterUI_INITIALIZED(event:UpdateEvent):void {
applicationUpdaterUI.checkNow();
}

XML update descriptor should use the following template:

version="1.0" encoding="utf-8"?>
xmlns="http://ns.adobe.com/air/framework/update/description/1.0">
>Version of the AIR file.>
>URL that points to the new version of the AIR file.>
>Description of the new application version>
>

Demotywatory Reader

Chcąc sprawdzić jakie są różnice w robieniu aplikacji webowej i desktopowej we Flexie, postanowiłem napisac prosty programik, który umożliwia w szybko sposób prześledzenie ostatnich wpisów na stronie demotywatory.pl :)

Wiem, że dużo ludzi tam zagląda – teraz będzie szybciej i prościej :)

Program do ściągnięcia tutaj.
Nie wiem czy się przyjmie, dlatego wszelkie dodatki będę robił dopiero jak program się komuś spodoba i ktoś go zacznie używać. A tymczasem będę ulepszał komponent z poprzedniego wpisu – chce go zrobić na podobieństwo ExtJS’owego DataGrida.
