Draw attention to the application of the user interface

• Detect if an application has the attention of the user

  Hey guys,.

  I have the BlackBerry to get the attention of the user (e.g. by vibrating) If an important event occurs.

  However, it does not vibrate if the application already has the attention of the user. What is the best way to check if the application has the attention of the user?

  Something to consider:

  -App is in the background (probably using Application.isForeground ())

  -If the BB is in the Holster (Application.isInHolster or something similar?)

  -If the request is put forward, but the screen is off. In this case, I still want the BB to vibrate and turn on the screen.

  Thanks in advance!

  Thanks in advance!

  Well, I found a solution for the bug here. I was using sockets to communicate between my headless and requests for benefits and in my slot look for disconnect events in my application without a head, I got this code:

  void disconnected()
  {
      ...
      _socket->close();
      delete _socket;
      ...
  }
  

  I then changed this slot to look something like this, that solved my problem:

  void disconnected()
  {
      ...
      _socket->close();
      _socket->deleteLater();
      ...
  }
  

  My guess is that I tried to remove the plug while he was still waiting to be delivered to her events. Using deleteLater(), the event loop is responsible for the removal of the plug once all the events have been delivered, preventing the application from crashing.

• deployment of a BPM Application large Oracle with several projects of the user interface

  Hello world
  I'm working on a large application with Oracle BPM 11.1.1.5.0.
  
  I use JDeveoper 11.1.1.5.0 to build the application.
  The application has many tasks user with a lot of the UI (one for each task of the user).
  
  My problem is, whenever I make a small change in the project, I need to deploy this, which includes a master project and five or six projects UI (for now) for tasks of the user.
  As demand grows, I'm sure that this will certainly become a problem.
  
  So my question is if I do this the good sense? or should there be a more effective way?
  
  Thanks in advance

  Hi Luke
  1. as a general rule, there is NO need to have a user interface project for an individual task. As initiator, approver, reviewer, LegalApprover etc etc, you have like 10 tasks (.task files). You can have just a single project of TaskForms UI and have taskDetails.jspx generated for each of these tasks. This is appropriately.

  2. any Application workflow must have only 2 deployers. Deploy resources are for real Workflow stuff that will have the main BPEL or process, BPM, human tasks etc. Basically, everything that goes into the workflow project. And another official of the deployment is that the REST of things means that the UI TaskForms project and other project support as useful projects, WebServices, EJB projects (if you have Web services). All this will be deployed as a SINGLE EAR.

  Lets take an example JDeveloper IDE point of view.
  1. application Name: SalesOrderApp
  2 workflow project name: SalesProcess (he is a a project jdeveloper project SOA or BPM Project type and has all human tasks, bpels, process bpm, rules etc.).
  3 interface user Project: SalesTaskForms (it is a form generated automatically for the first task you choose. Then for the rest of the tasks you can use this same project, to generate jspx for all others. WORK files. VIEW documents online on how to do it. I'll see if I can compile this list of URLS for you).
  3. support the EJB projects: MyEJBProject1 (some EJB project that connects to some specific to your back-end database project)
  4. support another Service EJB project: MyExtServiceProject1 (as another project EJB that uses data from an external source)
  5. some WebService project: SalesCreditCardValidationWebService (some WebService project to be deployed as. WAR file that performs a service).

  Try to apply the Concepts of SOA for each Service your application needs. Instead of putting all the EJBs and everying in one giant project, try to split their need logically commercial/sage and geenrate separate projects so that they can maintain as it is to other projects and other applications.

  Anyway, coming back, in the example above, you should have deployment just 2: 1 is the JAR file of SCA in the Workflow and another complete of the EAR file.
  (a) for the workflow project, right-click and generate a deployment profile to deploy all the workflow and NOT on the other projects of the user interface.
  (b) for each project individual genereate a profile of deployment such as MyEJBProj1, MyEJBProj2, MyWebService1, etc etc.
  (c) for TaskForms project, generate a deployment as SalesTaskForms profile. It is a WAR file.
  (d) at the level of the Application, create a new profile of deployment of the EAR type and now assemble all the projects in this EAR, with the exception of the Workflow project.

  First of all, you deploy file JAR of SCA of the Workflow. You need to redeploy this again only when you make changes to the workflow, humantasks etc etc.
  Deploy the full blown EAR file that has all the stuff (EJB JARs, TaskForm WARs, WebService wars etc.).

  At any time, you change your code taskforms or redeploy a java, ejb, EAR file.

  You should have a POT and an EAR to deploy at the end of the day. Infact this is how it should go into UAT, and production. They may not have many pots, multiple wars deployed. The reason why we have separated Workflow SCA Jar file is, because the workflow will not change frequently. And also older versions of SOA/BPM (before 11.5 FP) have a huge disadvantage. Whenever we deploy a workflow project, it will make existing processes VITIATED, unless you deploy a different version. This isn't a problem anymore for 11.5 + FP (Feature Pack applied). Therefore, be careful when you redeploy workflow project.

  Thank you

• Background image on the User Interface

  I'm trying to place a background behind my screen of the application image. So instead of the usual white, there would be a "background.png". I am following this thread with the blackberry API set

  http://supportforums.BlackBerry.com/T5/Java-development/drawing-bitmap-in-mainScreen-background/m-p/...

  So far, I tried to apply it within my own application, with the code to start as follows:

  final class UserInterfaceScreen extends MainScreen {
      HorizontalFieldManager _fieldManagerTop;
      VerticalFieldManager _fieldManagerMiddle;
      HorizontalFieldManager _fieldManagerBottom;
      BitmapField _bitmap;
      Bitmap _canadaImage, _ukImage, _usImage, _backgroundBitmap, _fieldBitmap;
      LabelField _label;
      BasicEditField _input;
      String _canadaCapital, _ukCapital, _usCapital, _capital;
      int displayed = 0;
  
      public UserInterfaceScreen() {
          super();
          LabelField title = new LabelField("User Interface Sample",
                  LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
          setTitle(title);
  
          HorizontalFieldManager _horizontalFieldManager = new HorizontalFieldManager(HorizontalFieldManager.USE_ALL_WIDTH | HorizontalFieldManager.USE_ALL_HEIGHT){
  
              //Override the paint method to draw the background image.
              public void paint(Graphics graphics)
              {
                  //Draw the background image and then call paint.
                  graphics.drawBitmap(0, 0, 640, 900, _backgroundBitmap, 0, 0); //240
                  super.paint(graphics);
              }            
  
          };
          _backgroundBitmap = Bitmap.getBitmapResource("background.png");
          _fieldManagerTop = new HorizontalFieldManager();
          _fieldManagerMiddle = new VerticalFieldManager();
          _fieldManagerBottom = new HorizontalFieldManager();
  
              add(_horizontalFieldManager);
              add(_fieldManagerTop);
              add(new SeparatorField());
              add(_fieldManagerMiddle);
              add(new SeparatorField());
              add(_fieldManagerBottom);
  

  Basically, I'm trying to combine the thread above with the user interface tutorial.

  http://supportforums.BlackBerry.com/T5/Java-development/user-interface/Ta-p/442781

  The question is when I run the code, I just get the background image, none of the other content is displayed in the foreground. I am this approach correctly?

  I'm not sure the solution you received one will work - it may well do, but the approach is different from what I do.  I based my image of background processing around comments in this article:

  http://supportforums.BlackBerry.com/T5/Java-development/MainScreen-explained/Ta-p/606644

  But if you look at what you said your screen, you will see why you don't see all your real fields.

  The first thing that you add to your screen is as follows:

  HorizontalFieldManager _horizontalFieldManager = HorizontalFieldManager(HorizontalFieldManager.USE_ALL_WIDTH | nouveau HorizontalFieldManager.USE_ALL_HEIGHT) {}

  You said this Manager to use the full height and width.  Then what place is left for any other Manager/field.

  You only add this option to provide abackground.  So actually, to do this, you must you add all your fields and managers in this HFM.  Otherwise that will expose after this one (which, as noted way they have no space to display in). I think you'll see something, if you replace this:

  Add (_horizontalFieldManager);
  Add (_fieldManagerTop);
  Add (new SeparatorField());
  Add (_fieldManagerMiddle);
  Add (new SeparatorField());
  Add (_fieldManagerBottom);

  with

  Add (_horizontalFieldManager);
  _horizontalFieldManager.Add (_fieldManagerTop);
  _horizontalFieldManager.Add (new SeparatorField());
  _horizontalFieldManager.Add (_fieldManagerMiddle);
  _horizontalFieldManager.Add (new SeparatorField());
  _horizontalFieldManager.Add (_fieldManagerBottom);

  But it probably won't be good, so you should follow the advice given in the previous Post or see the KB article.

• Offset of the user interface after update of El Capitan

  Hello. Since I upgraded my Macbook Pro late 2013 to El Capitan retina, I've known GAL of the user in function, mainly opening animation of safari and switching between desktop computers. These issues are only to make my user base, I created a test user and concluded that the test user was not the offset of the user interface. I have reinstalled the operating system, as well as talked to apple. Apple had me reset the Pram so that delete files, including:

  / Library/LaunchAgents

  ~/Library/LibraryAgents

  / Library/LaunchDaemons

  / Library/Caches

  ~/Library/caches

  and many other files like these.

  None of that helped, my UI lag is still there and fine. Also, I'm not sure if this is relevant; However, my recovery HD (available from start by pressing the alt/option key) is not an option. I'm not sure if the files I deleted with apple support caused it or reinstalling the operating system has done this. IM thinking delete files because I reinstalled the operating system using the HD recovery.

  Does anyone know how to fix the lag in the UI? I know other people have this problem, google search and this forum but no clear answer has not developed.

  Thank you

• Error variables look a tab after race change the user interface

  Hello

  I have a problem which seems to be a bit like this:

  http://forums.NI.com/T5/NI-TestStand/error-viewing-variables-tab-in-runtime-operator-interface/m-p/1...

  The VI I'm running is a step of edit of a type of step. LabVIEW checks if the property 'Step.Setup.ReadMeasName' exists, fills a listbox with her if she does. An another ListBox with all available measure names will also appear on the user interface. The user has an Add and Remove button to remove the 'ReadMeas' list box measures or add them to it of the listbox 'MeasNames '. Several names may be added/removed according to what is selected when you press the buttons. Once 'Fact' is clicked the VI writes the 'Ref' to the list box "ReadMeas" property to "Step.Setup.ReadMeasName", using a node to set the value of property that is passed the TestStand sequence context. If the property does not exist it creates.

  The only time where I have any problem is when I try to remove items from the property, after it is already initialized (i.e. non-empty). In other words, if I run the VI of teststand, put several names as in "ReadMeas" click on done, again run the VI (already added names appear in the box when the user interface is displayed, LabVIEW reads "Step.Setup.ReadMeasName"), then remove the names. IF "ThisContext.Step.Setup.ReadMeasNames" has opened in the tab 'Variables' step when you try to remove the names, I got this message in the Variables tab: 'one or more errors occurred. Please save your work and restart the application. "If I'm careful of not having expaded 'ThisContext' in the variables tab, but check the property before and after the removal of names in the list it does not work properly, and there is no error.

  This isn't a big problem because I doubt that the end user will check to see that the property has actually filled, but I still want to fix the bug if possible. I installed the patch for TestStand 2010 and the .net Framework 4.0. Someone has an idea of what might be happening here?

  Thank you

  -Josh

  Josh-

  Looks like you are running in a known issue 193751, which is documented in TestStand 2010 and 2010 SP1 known issues list. It is a problem that we intend to fix in a future version of TestStand.

  I hope this helps and I'm sorry for any inconvenience this issue may cause you.

• How can I update the user interface controls in the UI thread

  Hi all

  I want to do a custom image to display this URL source support.

  I start a thread to ask the image of the network data, and then update the display of the image with the data, but I get the error:

  ApplicationPrivate::resourceManager: ERROR called from the thread of user QThread (0x81eeb8c) interface
  ApplicationPrivate::resourceManager: A user interface thread named method

  It's my code segment:

  class URLImageView: public CustomControl, public QThread
  {
  public:
      URLImageView();
  private:
      void run();
  
      ImageView* mImageView;
      Container* mRootContainer;
  };
  
  URLImageView::URLImageView()
  {
      mRootContainer = Container::create().background(Color::Gray).preferredSize(100,100);
      mImageView = ImageView::create().image(QUrl("asset:///button.png"));
  
      mRootContainer->add(mImageView);
      setRoot(mRootContainer);
      start();
  }
  
  void URLImageView::run()
  {
      //get data from network
      //...
      //...
              //create image from binary data        Image* image = new Image(pixelBuffer);
      mImageView->setImage(image);
  }
  

  I know that in the old BB OS (Java Platform), I can get the lock of event request like this UI:

  synchronized (Application.getEventLock())
  {
          // I can update UI control here
  }
  

  Is it same way to Cascades BB10 or what is the right way, if I want to update the user interface in the UI thread?

  Thank you

• to access the QML attached objects in C++ and best practices for the handling of the user interface in classes

  Hello

  I have in fact 2 queries

  (1) how can we access attachedobjects defined in QML in C++?

  (2) I'm loving development on Blackberry 10 C++ is one of my favorites. But I'm a bit lost when it comes to managing the user interface in classes. For example when we create the project through momentics we have a class called ApplicationUI. It manages all the (default) user interface commands, we in C++. as for example creating the document qml and setting as root user interface, etc. I am now working on an app that have NavigationPane as root, and then I continue to push pages (like the screens). But now the code for all pages is inside my ApplicationUI. What is the best practice to keep the UI for each page logic in a separte C++ class?

  I also develop for Android that a separate class for each activity, this code does not mingle for each activity. Please guide me how can I keep logic of user interface of each Page into a separate class of C++?

  regarding your second question:
  I think this is the simplest approach to keep all things in the UI in QML. You can easily put things into separate files.

  If you want to use c ++ to the user interface: can be done, too. just put it in separate classes and include those in your application class.
