Widget Gears httprequest

• Loading an image out of a widget... Legend/display until this only charged text?

  I create an image using google static graphics and display it inside one of my widgets. Once the web request is made to the chart, I place the on the form, but I would like to be able to set the ALT text or something to show somehow a text until the image appears. Any ideas/thoughts?

  

  I did similar things in the widgets that might be of help in this situation.

  When your page loads all first use an image of "loading" to act as a space reserved where the graph is supposed to go.  Make sure that this placeholder image is generic and local for the widget so that it loads instantly.

  Then use AJAX to retrieve the table.  Specifically, I use the Gears HTTPRequest object because it has a responseBlob property.  Once you have retrieved into a blob content save your image graphic/blob with a unique name locally on the file system (be sure to white list this place).  Then replace the placeholder image "src" with the local path to the saved image.

  Now at this point you're probably thinking... Why the hell would I do that?

  The reason why I suggest this is because caching is not enabled in the widgets.  By doing this you are essentially caching the image to the next, and it will be much faster.  On the next view, if your data points in the chart are the same, just pull the image directly from the local file system to the place to recover again.

  It becomes like your own little hidden on the file system that you control.  We will also be providing built in caching in a near future of widgets that will help you in this scenario.  But it is also a good technique for all AJAX requests for data that are just snippets of XML/HTML.  Put in browser cache only put cache files and not blocks of data retrieved by XMLHttpRequest.  I found creating a small cache of the generic file system is quite simple and quite convenient.

  I hope that gives you some ideas

• Widget that uses google gears on Blackberry 8530 will not work

  Hello world

  I have developed a widget that uses google gears and the file gears_init.js as the method to use sqlite. I am able to load and to see the widget to work on the 8530 Simulator, however it seems that the sqlite database is not created, and all I see are my html pages.

  Does anyone know what could be the problem? I have also deployed the app my physical device to the 8530, but are experiencing the same problem. I'm on OS 5.0.0459 and Google gears version 0.5.0.0.

  Any help is appreciated.

  Thank you.

  Hi drjg22,

  Make sure when you are finished with any game registration you explicitly close it.  If you do not explicitly close your record sets it will cause a memory leak.

  Do a quick check to see if your code is close your recordsets.  The signature of your error as this sounds could be the cause.

• OS5 HTML5 gear - openDatabase fails - undefined database

  Hello..

  Today, I tried to create a simple widget with intervention from the database. I started with reading a few articles on the blackberry developer pages and found some interesting resources. Especially since the support gear was abandoned with OS6.  Widgets my future must run on OS5 OS6 devices, so I followed the instructions to support the gears using HTML5 in the BlackBerry Widget applications.

  After reading a few things about this Api WebSQL, I tried to create a little Gizmo, which stores a simple text input in the database. I tried the WebSQL Code in my browser (Opera) normal and it worked, but not when I test it in the BlackBerry Simulator.

  I created my widget as described in the tutorial "how to avoid recompiling a BlackBerry Widget during development.

  In my widget, the "openDatabase" call fails, even if this function exists. I tried to get the error with a try-catch block information, but the call fails "silently". After investigating this feature (display its content in a textarea component) I found creating a database object in a try-catch block.

  When I try to create these objects in database for me, it throws the following exception: ReferenceError: "Database" is not defined.

  You have any ideas?

  I use the widget in a Curve 8520 Simulator, OS Version 5.0.0.50 9, Version 2.13.0.97 Simulator.

  If you would like more information, please ask!

  Thank you for your help and I hope that my English is not too bad. (It is not my native language)

  Here is my html and javascript code:

  You simulate a SD card inserted in the Simulator?  A SQLite database on 5.0 must either be stored on a card inserted SD or built in the MEM card.  Built in card MEM is only on storm devices and 9000 "BOLD".

  If you simulate a SD card on your curve Simulator, the database must be created

• Output of widget with red button.

  Hello

  This blackberry.app.event.onExit (handleExit) function does not work when we exit the widget with the red button.

  Is there another function to intercept this event?

  If I use the red button to leave my application when I reopen it the application, I got a "file system (12) error" error when I do that:

  Private = google.gears.factory.create('beta.database');
  _db. Open ('notesBase');

  Any idea?

  Thanks in advance

  The (red) end call button will not end an app.  He moves to the background.

  If you want your 'handleExit' method that is called when the user clicks on this button, register you the handler in your application:

  blackberry.system.event.onHardwareKey(blackberry.system.event.KEY_ENDCALL, handleExit);
  

• Widget displays daily - best solution?

  Hello

  I made a widget that shows 40 new each morning.

  For the moment, I push the news every morning, as a string of 40.

  When my widget news, it stores it in a database of google gears.

  On my index.html page, I have a table. Each line is a new.

  My problem is that it is very long to load.

  ------------------------------------------------------part of my load method ------------------------------------------

  If (rs.isValidRow ()) {}
  Add entries to the table

  While (rs.isValidRow ()) {}
                                     
  "linkTable.innerHTML +="."+ rs.field (1) +""+ rs.field (2) +""+ rs.field (3) +"";
                    
  RS. Next();
  }
  RS. Close();
  }
  Data.Close ();

  ------------------------------------------------------------------------------------------------------------------

  If I go to another page and back to the index.html page, I still have to wait for loading...

  What is the best solution for this kind of request?

  Thank you very much

  The manipulation of the DOM is extremely costly on a mobile browser. Whenever you update the DOM it will recalculate a layout and re - calculate the information on the page.

  In your code example, you would be able to accelerate a lot just using a variable to concatenate all your DOM elements in the first loop and then just call "linkTable.innerHTML" once to then update your page.

  Your code is now updates the DOM 40 times and whenever it updates, it must recalculate the page layout. Each update of the 40 will be progressively slower because the DOM increases in size.

• Widget Sqlite using a packaged .sqlite file?

  If I have a sqlite database must be installed with my widget on the package, how to access these data in the widget? I read that the documentation of gears and 'fix' and 'Detach' commands are the two people with reduced mobility?

  You will not be able to distribute a database SQLite pre-packaged with your application.  All data transmissions are encrypted on the device and cannot be replaced.

  You will need to build your database through JavaScript.  For your data by default, you can incorporate XML files in your widget and then loop through them to feed your database in a worker thread.

• Wow. Display encrypted Gears db

  I just read a post that a little amazed all hope of debugging easily using the Sqlite database. http://208.74.204.192/T5/Web-development/widget-SQLite-using-a-packaged-SQLite-file/m-p/380088/highl...

  When I try to open a Sqlite database created in the Simulator (using the Sqlite database browser or browser Sqlite Expert), I get the message: "file is encrypted or not a database.

  I take this means that using any tool is impossible on the basis of the gears, since they are encrypted?

  Yep, to clarify, non encrypted db should be used for debugging purposes.  When your application is ready for production, allow the application to create the correctly encrypted db.

• Future gear

  In light of Google's announcement that they are no longer developing Gears and gradually in favor of HTML 5, how does this affect the Widget SDK?

  That HTML 5 standards evolve, RIM will also consider to provide support in the rendering engine of the browser that is shared by the native browser for BlackBerry and BlackBerry Widget SDK.

  At this point, there are no current plans to end support for the gears in BlackBerry Widgets or the browser.
