My first Playbook application

• Need help developing a Playbook application

  I need to write a user interface application based for playbook that needs to interact with C++ code

  an existing application of the playbook.

  I was wondering what would be the best option

  #1 develop the user interface using native C/C++ SDK - interface with C++ application code

  #2 develop the user interface using native Java SDK - Java interface for my C++ application

  #3 develop the UI using AIR - use a feature of the NDK to interface with C++ library code.

  Option #1 seems straight forward. Option #2 and #3 might need an interface to call a C++

  methods of Java or AIR.

  As I'm new to developing Playbook applications please let me know what would be the best option.

  The PlayBook has no support for Java outside the Android player, resulting in applications with a feeling distinctly not native.

  However, AIR has an interface fairly good native extension let's you call native code. AIR also has a current user interface infrastructure which is very good.

  The native SDK currently has no native toolkit UI and will not be until the release of Cascades. So if you design your user interface with the native SDK, you will need to bring your own UI toolkit. You'd probably want to focus on Qt.

  So, unless you are already a Qt or willing developer to wait for waterfalls you probably want to do UI in the AIR.

• Should I wear my Playbook applications to BB10?

  As the title.

  My apps is able to automatically resize with density and different screen size.

  My application is an a porting android on the Playbook.

  Can I use this app BB10?
  If so, what I need from my android/playbook application to port BB10?

  Android applications on the BlackBerry PlayBook would be also supported in BlackBerry 10.  The main differences that you need to consider is the different screen size.  But you mention that your application handles itself.

  Download the Simulator BlackBerry 10 Dev Alpha and give it a try.

• First JavaFX application with time sequential process

  Hi all

  I'm working on my first JavaFX application.  I have a user (view) UI elements in place, I have a controller that works properly (with the exception that I will mention below), and I have a model that works properly (processes data correctly), but the model code was written to run under a user interface.

  What I want to do is the following.  When the user clicks on the "Run" button, the user input is passed to the model via the controller and the data is processed.  It's a do - once a sort of thing where the input is transformed into the output and that's the end of it.  The user interface can be reset and new entry provided, and all this happens again by clicking the run button.  Here's the problem: the treatment has several steps that need to occur in order, but some may take some time.  I want to provide feedback via a message (what is done) and overall progress via a progress bar (the two items in the current user interface).  The problem is that I am still very confused on how to accomplish the user comments.

  The user interface was built in SceneBuilder, and I attributed to the onMouseClicked event to call the runButtonClicked() method in the controller.

  The runButtonClicked() method calls the private methods that run the processing steps (I'll do something more intelligent exception - please ignore that for now)...

  public void runButtonClicked() {}

  runButton.setDisable (true);

  sdfFileBrowseButton.setDisable (true);

  outputFileBrowseButton.setDisable (true);

  try {}

  prepareSDFFile();

  prepareModels();

  collectDescriptors();

  makeSamples();

  evaluateSamples();

  writeResultsToTextFile (results, outputFile);

  } catch (IOException exception) {}

  System.out.println ("Caught an IOException:" + exception.getMessage ());

  } catch (JAXBException exception) {}

  System.out.println ("caught JAXBException:" + exception.getMessage ());

  }

  }

  Each of the calls in try-catch are tasks that need to be linked in the order listed.  Some of them may take a long time (for example, collectDescriptors(), evaluateSamples(), and writeResultsToTextFile().  The work is not done in the controller.  The controller creates instances of classes that do the actual work (this seems to be a departure from most of the tutorials I've seen - it seems the model and the controller are mixed in the tutorials).

  I would like to alert the user about this step is execution (by means of a message in the user interface) and at what stage of the process as a whole is in (through a progress bar).  It would be nice if the progress bar might reflect the status of each individual step (back to 0 at the beginning of the next step), but given the bar just reflect more all the advances (e.g., how many six steps were finished) would be sufficient.

  I also want to be able to manage a Cancel key event and just stop the whole process and reset the app (lose whatever work has been done is OK).

  -I can truly say what should be the best approach.  None of the examples in several tutorials, I went on that have really touched on this type of sequential process.  I would like suggestions.

  Thank you

  
  Dave.

  
  

  Suggested approach

  What you describe is a quite classic case to use the utility javafx.concurrent (task and Service).

  Your application is a perfect fit for the use of these services, which will provide you with:

  1. an execution thread concurrent to run your journal of the current process

  2. a feedback mechanism of thread-safe for the progress that you can link to a ProgressBar for interactive progress feedback.

  3. a feedback mechanism of thread-safe for messages that you can bind a label to your interactive status feedback.

  4 code example that illustrates the ability to cancel and restart the process.

  5, a setter callback method of success that can be configured to provide a result and decide on the success.

  6. a reminder Set accessor method failure which can be set to make an exception and to take measures in case of failure.

  Task and Service samples

  There are a lot of examples of tasks if you search for task of JavaFX.

  There are also great documentation in the javadoc task and Service .

  Here is an example of using a service of JavaFX.  The example is a bit old and uses does not use some new features of the API such as setOnSucceeded or setOnFailed, it also uses models of generator now frowned upon, however, the bulk of it is still relevant to what you want.

  Here is another sample more complicated to make 300 cards off screen and save the files in JavaFX, although I doubt that your task should be as complicated and probably a unique control service is all you need, in order to not pay too much attention to the more complicated example unless you need this kind of functionality.

  Here's another simple example for Re: create several parallel tasks into a single service, which shows in fact sequential and a side event of the stage of the tasks within a service.

  Progress can be reset between the steps, so that the message indicates the current step and progress indicates the status of the market rather than overall progress.  You can expose different processes for feeding of the overall progress back in addition to the progress of the step.

  If you're still having problems, I'm sure someone on the forum could easily model a draft sample application illustrating the techniques based on the info you provided in your question, just ask if you would like that...

• Some Notes after completing my first Mobile application...

  I just finished my first mobile application with Flash Builder Burrito AIR.  It took me a little over 3 weeks.  Even though I'm an experienced programmer, I had no experience with Flash Builder, AIR, ActionScript, etc.  If so, I could fall out this app in a week!  I am very impressed with the ease of development compared to some other platforms I have developed on (native Android, webOS, titanium and a few others).  That said, I ran into a number of issues that I believe, if properly addressed, would be very beneficial for developers, users and the platform as a whole (so I hope that Adobe employees visit this post and read on!).

  
  

  Forms and fields

  
  

  Support for the forms could be much better.  Any questions I have met, those related to fields of form took longer time to resolve that any other.  Three Markdown really however...

  
  

  1. There is a kind of property "placeholderText" which displays its value within a field unfinished (gray part preference).  When the user clicks in the text field should disappear.  If the user leaves the field without entering anything, it should reappear.  This will cancel the need for labels they are currently used, save precious screen space.  It was not difficult to write a function that does this, but it's something that should be built in.
  2. Form validation tools are essential!  There should be a way to test & flag common types of fields that are not filled correctly (single currency, numeric, text, email, etc.). Built in functions that do this would save developers time.  I created my own, but I have not found a way to change the background or color of the text fields on the fly.  Instead I just asked the user without bringing out the specific areas.  This may be due to my inexperience with this platform, but once again, it is something that developers should not have to reinvent the wheel with over and over again.
  3. There should be a way to specify which keyboard is displayed whenever a field is selected.  For example, if I know that the user enters a zip code and then a keypad should display.  There are a multitude of available keyboards, but the ability to switch between text and digital should be the bare minimum.

  
  

  Guests user

  
  

  I found it strange that there is not a way to quickly invite users.  I tried the function of Alert.show () without success.  I got my own all kinds of bearing warning system.  It works very well indeed, but still...

  
  

  Projects under implementation

  
  

  It is something minor, but annoying.  I don't know if it's a problem of Flash Builder or Eclipse issue, but if you run an application and you already have an open instance you receive an error indicating such.  It would be great if she is simply closed the old instance and opened a new.  I know, very minor.  I'm just saying...

  It seems to be missing the library 'png' on the link phase. Can you confirm for me that the link against it?

  Go into the settings of your project, build C/c++, select tab "settings of the tool. You will see the folders 'QCC Linker, libraries' on the list. You must have "png" it.

  Another way to check is when you compile look at the last line (the link phase, starting with "qcc o", you should see a '-lpng ' modifier.)

• The missing PlayBook Application icon

  Hi all

  I hope someone can help me with a problem I have. I am currently coding my first app webworks for the Playbook, and everything went well except that my application icon does not appear. I tried my compiled bar line on the Playbook 1.0.1 Simulator and a physical Playbook running OS 1.0.7.2670, which do not show the icon. The icon I use is 86 x 86 pixel, named "icon.png". I have included the call of the icon in a file ' blackberry - tablet.xml "as:

  
     
     
     
      Core.All
      0
      1.0.4.0
     
          Icon.PNG
     
      strangled
  

  (the names of the author, authorID and the editor have been removed)

  I also called the icon in the config.xml file:

  
  http://www.w3.org/ns/widgets ".
  "xmlns:RIM ="http://www.blackberry.com/ns/widgets"
  version = "1.0.4.0.
  RIM: header = "" RIM-Widget: RIM / widget ">"
      Game
     
      Game
      <>
  RIM: copyright = "2011".
  email =""
  >
     
      <>committees mode = "landscape" / >
  

  My sidebar file was compiled using Webworks 2.1.0.6. The three files ("blackberry - tablet.xml ', 'config.xml',"icon.png") are located in the root directory of the application. If you need more information to help me with this problem do not hesitate to ask and I will answer as soon as possible. Thank you in advance for your help!

  I assume you are using the file blackberry - tablet.xml in the execution of an application not signed in the PlayBook device. This file is not necessary for signed applications, only the config.xml file is required. And for your problem, I guess it must solve it. In blackberry - tablet.xml , use the following code for the icon.

• Who go first?  Applications or the OS El Capitan?

  Hello.  I am running Cougar and to finally upgrade, as Safari works barely any longer, and I guess that it is only at this time.

  I have a couple of 3rd party Applications that I've already updated as they will continue to run on the ML and THIS, but I don't know what to do with those who, like Sonos or MyHarmony.   Spend these first, although they will be more accessible on my ML?

  Or first switch to CBS and I will then be able to upgrade the Sonos & MyHarmony?

  I have Time Machine on a time Capsule backup so I guess I can always restore if there is a gigantic fiasco, but at some point, I'll have to upgrade.

  I use an iMac 2012 (later) 2.7 GHz with 8 GB

  All opinions are appreciated.

  Lilskye

  Hi Lilskye,

  Thanks for the detailed question!

  If you have saved any Time machine, you can go ahead and check the developers Web sites to see if their software supports El Capitan.

  If so, you can go ahead and update the software first, and then upgrade your Mac to El Capitan.

  I always advise first put the software, otherwise, it may be inaccessible when you use the new operating system.

  Thank you

• vendor name change affects existing playbook applications?

  I would change my name of the app World vendor and I was wondering how it would affect the apps (playbook) existing. For example, when I get a new key of LSB and make a new cert p12 for the new name, I'll be able to sign an update of an application with an existing application ID? Or the signature/app install would fail due to different names/certs? I had problems with the evolution of the certs/names in the Office of the AIR, so I was wondering if the same applied to the playbook. Thank you.

  With a new key, if she has the same name of provider or not, seems to make an app to look like a different application (as others have pointed out a number of times).

  So, if you change the name of your provider requires you to get a new key, the app will appear different.

  If your application involves the application-specific data, I suggest that issue you an update to the old app that allows you to export and make it clear to users who install the new application that they will not have access to their old data until they export it and import it into the new application.
