• I have problems with JavaFX applications run on raspberry pi!

  I have problems with JavaFX applications run on raspberry pi. I did all the steps of the course videos: overclocking, without comment that I had to uncomment on the framebuffer, but Exceptions are always produce. Demonstration of fireworks as an example does not work. Someone went through this problem? Java applications are ok. Like the versions of java in netbeans project and also on 'Properties' and they are all JDK 8. So if anyone can give a clue, I am very grateful!

  Can you provide the exceptions that you got so I can help you better?

• 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.

  For more help

  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...

  I did some research and aparently you must republish the same answer for me to be able to show your answer as being correct (for some reason, it is not editable)

  Answer:

  You can launch an application Java to the main thread by calling Application.launch, but you can call it only once per process or an exception will be thrown:
  http://docs.Oracle.com/JavaFX/2/API/JavaFX/application/application.html#launch%28Java.lang.class, %20java.lang.String...%29

  ---------

  Partners:

  The cycle of life and the management of threads that run user by the JavaFX application code is documented in the javadoc for JavaFX Application:
  http://docs.Oracle.com/JavaFX/2/API/JavaFX/application/application.html

  Conditions of application output is kept by Platform.setImplicitExit:

• methods of a JavaFX application from another application

  Hallo.
  
  So, I did some work on JavaFX 2.0 integrating graphics into a program called Max/MSP. It is a kind of Visual language for handling the music. Among it's features is the ability to write your own classes java, extended by the MaxObject class and create the custom components in your Max Patches. I received a MaxObject to launch a JavaFX applications, so I know that this part can be done. Now, I need two programs to talk properly with each other.
  
  So, what I'm looking for is a pretty standard, reliable way to get ApplicationA, i.e. which launches application (and thusly can pass arguments by hand), to be able to transmit information in application B and vice versa. I'm assuming that someone else out there he wanted a JavaFX application to interface with another piece of java code. An Advisor on what should I look for in? Both applications are running on the same computer. And I hope my question is clear decently...
  -Jean

  Hey John,

  I would like to try some of the following to refine your question:
  * Put your launch within another thread code to see if that stops the problem of blocking
  * use a random value that is passed to your application instead of 42 so that you can tell if new instances are created, etc.
  call a different method for bang for your second call to the method just separate the flow to isolate your question

  Something like:

  public class MaxPart extends MaxObject {
  
      private boolean started;
      private Circles circles;
  
      public synchronized void bang()
      {
          if (!started)
          {
              outlet(0, "Starting Circles application...");
              started = true;
              new Thread()
              {
                  public void run()
                  {
                      Application.launch(Circles.class, null);
                      outlet(0, "Circles application launch completed");
                  }
              }.start();
  
              // you could do some synchronized blocking here to wait for the instance to be set, try just doing a
              // simple sleep for now and add synch in if it works
              try { Thread.sleep(2000); } catch (InterruptedException e) {};
  
              circles = Circles.instance;
              Double randomValue = Math.random();
              outlet(0, "Circles assigned random value: " + randomValue);
              circles.setValue(randomValue);
          }
          else
          {
              outlet(0, "Circles is already started, not starting another one");
          }
      }
  
      public void anotherBang()
      {
          outlet(0, "Circles random value was: " + circles.getValue());
      }
  }
  

  Either way, you mention that you want to use the Singleton pattern. You pretty much are already - the 'instance' is a singleton that gets the value once (when the Application is launched) and is then used in the world. There is nothing real magic of singletons.

  Also, just to let you know the 'main' method in your application of circles is not needed or used. The bang method directly calls the launch. You only need this main method if you want to run the standalone app of circles (which is still useful for testing).

  Hope that helps,
  zonski

  I just bought an Iphone 6s and not yet am possession of en from the Sim Card. Ook, do you know if I can use the phone including applications via Wifi and put the chip later? Thank you. Renault JL

  No, because if you bought a new iPhone, then you need a SIM card to activate it before you can use the wifi applications.

  This is a phone after all, you don't need a sim card any to be able to activate it.

• 2007 Mac Pro screens with pixelated strange habits travel &amp; can't access files or applications.

  Have a 2007 Mac Pro 2.66 GHz Dual-Core Intel Xeon (OS 10.7.5). Today both screens started having strange pixelated, modes of travel, and we can not access files or applications.

  Thought that maybe the video card went bad, but would not be prevented from using the apps, or click files would it? Have to keep restarting the box. Working temporarily, then pixilation and locked files races again.

  Ideas or suggestions?  Don't know how to solve problems

  Thank you!

  -What video card is installed?

  I suspect that the pixilation is due to a video card problem.

  Open the cover, with Mac off nd unplugged and clean inside. If the map includes a fan make sure it turns freely.

  -What do mean by "we can't access files or applications? What is going on?

  Try to download to your computer, iTunes then sync it to your device.
