  Hello. I am very new to JavaFX so please forgive what may be an obvious question.
  
  Can anyone provide a code example to create a menu entry for example, file-> exit to quit a JavaFX application?
  
  I can create the menus, but I don't know how to perform the actual output.
  
  Use the setOnAction method? What is the code performs the actual closing of the app?
  
  Thank you.

• Preserve the State of the radio between the frames button

  Is there a way to CS3 to preserve the radio button state (selected or not) from the frame to the frame?

  I have a multi application where users select Yes or no (radio buttons) to an array of questions; they complete these questions they click a button before moving on to the next section (set of questions). But I'm wanting to add a back button that allows them to go back and change their answers... How can I preserve the State of radio buttons clicked on the previous images, so that when they return to a previous image (or frameworks) these radio buttons, they chose are still selected?

  If the design is chronology based on you need to configure a form any memory (for example, a table) to keep the selection data so that when you enter a framework will you use what is stored to configure things.

• How to maintain the same State of the application after closure and reopen the app?

  Hello

  My problem is while accessing the request, if I close and reopen the application then the previous state of the application is at a loss.  Please help me to maintian the same State of the application after close and reopen the app means reopen after application, enforcement should be focused on the last viewed item and I used the browser component if I reopen the app, then content browser also be there under the previous state.

  Advanced thanks for any help.

  One proposed by Simon is 'Close' and that you save enough information to rebuild your Application in the State was restoring it when it is reopened.

  Alternately, instead of really close your application, you could just put it on the bottom using

  UiApplication.getUiApplication () .requestbackground ();

  Once in the background, when the user selects again your application it will start immediately and will be exactly as it was left.

  This does not, of course, runs through judgment or commissioning of treatment you could want, so, for example, will not store all resources you want to put away when you know that the user is going to use your app for a while.  To help with this, look at the Application.activate () and Application.deactivate () methods.

  I hope this helps.

• 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...

• Looking for a replacement for opening that preserves the adjustment (in opening).

  Photos for Mac OS is not rushing to meet the needs of more than 90%, so I need a replacement of spares for Aperture.

  I have a library approaching 100 000 photos so import is a major concern. I'm looking for an app that will preserve the adjustments made within the opening. It's almost not negotiable :/

  Thank you

  Photos for Mac is the only application I know of, who keeps the aperture settings. Too bad it does not your other needs. It does not allow to customize the workspace with presets like Aperture, it does not support the presets for metadata and bath not changing, almost no support for the referenced images.

• How do 'Enum Control' disabled during the execution of an executable application and make activated when the application is stopped/abandoned?

  Hello

  I use a "Enum control" on the façade of an executable application built with application builder for LabVIEW 2013 full professional development system. I want Enum control remains activated prior to execution of this request so that I can choose any value from the list of available numeric values, but when I run this application; Enum control should become disabled so that the user can not select another value in the list of data during application execution values so that the default setting remains unchanged during the execution of this application. Enum control must also be activated when the application is stopped/abandoned so that the user can select any value.

  Could someone pls suggest a solution to this problem?  If I select the active state' to 'Disabled' in appearance tab then all listed values becomes disabled.

  Concerning

  Jamal

  I suggest to use the node property of persons with reduced mobility.  You can then disable the enum at the beginning of the program and then activate it in the judgment.

• Cannot connect in application translated when other than the main language is selected

  Hello

  I am facing a problem due to a translated application.

  Whenever I'm trying to connect to the translated application (which means that I enabled the language of the application to another language in the primary) I will not be connected. It ist, no error message is displayed. Apex just redirects to the login page.

  I'm currently debugging the connection process, but unfortunately I did not help. Maybe someone is able to tell me what means this debug. Although the research he gave some results, none of them were useful in some way.

  It is translated into Polish (pl). There is a running application process "on the new instance", the setting of the APEX_UTIL. SET_SESSION_LANG('de') for testing purposes (later it will be dependent on the language of the browser).

• 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?
