• Feedback from the user interface

  In the Simulator (090), when the user selects the gear (top right) to display a list of parameters to select, the bar of the background and button scrolls down.  However, it is not intuitive how to return to the "main" screen  Still, the down arrow in the main screen button bar pointing downwards and is grayed out.  There seems to be a second "up" button placed in the Center, but it is masked by the "Media" button  Suggest that it is more obvious to select and restore.  Suggest you hide the button bar, make the less gray background and make the arrow more obvious upward so that the user knows that they can select the area to restore.

  Don't forget, this is still in phase beta/Simulator, I am sure that the final design of the user interface will be better/more intuitive.

• How can I get the user interface in af:SelectManyShuttle

  Hi all
  
  I downloaded the screenshot of the user interface I have to build using af: selectManyShuttle in the URL below.
  
  
  http://www.freeimagehosting.NET/a5f7c
  
  
  Can you get it someone please let me know how I can achieve this or is this still possible using ADF.
  
  The more important thing to realize in the user interface is icon next to each list of items under certain conditions.
  
  Thank you

  As far as I know, there is NO direct support for hierarchical select several shuttles.
  But you can create a custom hierarchical select many shuttle tree/tree-tables on both sides and having some features/custom buttons to add/remove items.

  If you use tables of the tree, you should be able to place the icon.

• 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

• WIN8 registers touch but no reaction from the user interface?

  Anyone having problems with Win8 button when your fingers are clearly registered (Windows gives this feedback from the spherical ripple effect) but the user interface under your finger does nothing? No not the button and so on.

  I live it with some Chrome for example, with the small button tab when it is near the top edge of the screen.

  If I drag the window to the center of the screen, I have no problem with getting keys recorded. Hit the button new little tab gives no trouble.

  When user interface elements are close to the edge, no reaction, even if the wave indicator appears.

  Cannot know if it is a driver or a HW problem. I use X220T.

  Example screenshot

  May be a problem with Chrome, in fact. Tried with Firefox and the new tab button is a lot easier to hit. ---> will give Chrome devs a hint

  EDIT: what you know! The new beta version has already dealt with this issue:

• Flatten to a string to send arbitrary objects by messages from the user interface?

  Hi people,

  I am trying to send arbitrary data by messages from the user interface defined by the user to my labview interface. Something funny happens then: if I send the data through the message of ui, it seems I have something strange. There is only one character or nothing in the message of the user interface that reached my reminder.

  It seems that flatten channel also creates control characters that are interpreted by NI TestStand and Labview not as members of the chain, and for this reason I only get incomplete data. within the action of testand, which creates the flattened data, I put a dialog box to display the string data, and it seems that at least up to 255 (ascii) characters are used.

  Is there something like uuencode/uudecode to avoid this problem?

  Thanks in advance

  Okidoki, found.

  His «binary"produced by «Flatten the string» string Apparently I thought, the LabVIEW data type is incompatible with the API of TestStand from LabVIEW. In conclusion I would classify this as a bug (sorry people, at least there should be documentation) API for LabVIEW TestStand 2014.

  As a solution, I use flatten it in XML, which is a printable and human readable 'normal' string.

  It was trial and error, and I'm not enjoying this.

• custom user interface will not close

  Hello

  I have created a custom UI TS, based on the graphic interface delivered simple TS. When I close the user interface, the process remains in the list of windows processes, I can put an end from the windows Task Manager. This only happens if the adapter of LabVIEW is set to Run-Tiime engine. If I select the LabVIEW development system, the GUI will be entirely closed.

  Hi Madottati,

  the first thing that comes to mind is to close the process programmatically as you do in LV, when you build an executable file. An example how to do this is shown here:

• How to get TS::SequenceContextPtr to customize the user interface

  I want the file of the custom, user interface sequence value therefore need to take stock of the TS:equenceContextPtr, anyone know how to get this point.

  Is there a reason that UIMessages are not enough?

  Just off the top of my head, here are a few concerns with the not not using UIMessages:

  1. How the user interface is unknown when the file of the sequence is developed to set the value.  Without an event or some sort of synchronization you can do exactly that.  UIMessages not only to ensure the right information, but they help also with synchronization.
  
  
  2. The engine does not know this information, and view of execution manager knows that the information for the current execution it is linked to (which changes throughout the life of a series of tests).  Basically, recall of front end, model, and other factors may spawn short executions briefly related to the Manager view of execution.  So if you take the context of the sequence of the current run is perhaps not the right one.
  
  
  3. Writing a user interface will be couple the user interface to your specific sequence file.  At this point, you can use the network variables or global variables or global queues as well.  It might even be better options.

  The situation you describe is exactly why the UIMessages were created.  Maybe you can help me understand why you are set on the use of pointers, you already have?  There might be a better solution for your case if I'm misunderstanding you.

  Thank you

• How to get an array of integers to user in the User Interface

  Hi all. I'm not a very experienced user of the CVI. I have almost exclusively coding in LabVIEW but have a client who wants all of their work in the CVI.

  I've been very fruitful so far (set up a Modbus API from scratch that supports all types of connection) but am confused on how I can get the integer multiples of the user without limiting the number of integers I can get. Essentially, I need to be able to get an array of integers to the user.

  General information, I am building a user interface to test my Modbus API. There are Modbus functions to 'Write multiple registers' and 'write multiple coils. I want the user to be able to enter all the values they want to write in one command.

  What is the best way to get an array of integers through the user interface?

  The easiest way is probably to allow user input in a textbox control numbers: items can be separated by spaces, commas, or even a line break (using ctrl + Enter). You will then need to extract the string from the TextBox and analyzed for numeric values using any non-digit character as a separator: strspn (string, '0123456789'); can be used for this.

  More complex, another possibility is to use a table control to receive user input: you Dresses an empty table with a reasonable number of roews, or you need some codes to add new lines as long as the user fills all those already existing. On the other hand, it will be easier since data recovery in a simple statement, you will all return values: GetTableCellRangeVals (panelHandle, PANEL_TABLE, VAL_TABLE_COLUMN_RANGE (1), table, VAL_COLUMN_MAJOR);

• 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-

  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.

• The best way to separate the user interface in the model LV 2012 queued Message Handler?

  If you create a new "queued Message Handler" new model 2012 LV, you will see a blue box in the case of "Update view" that says the following:

  Code Recommended - If you wish to decouple the Message Handling Loop from your user interface, consider creating User Events (like the "Stop" event in this VI) to message the Event Handling Loop whenever the user interface needs updating.
  

  I would like to give a suggestion, but I am struggling to find the best way to do this and still keep code modular.  The template creates a user - Stop.lvlib "event with a create/Destroy/fire Subvi.  I would like to create a library of "User event - Update UI.lvlib" similar with similar Create/Destroy/fire Subvi keep this new modular and separate user event.  The problem, I am struck, is that there may be only two hydrants in case Structure dynamic event so, how I modularlize creating user events in separate SubVIs and always maintain this dynamic event terminals?

  As a follow-up on the issue, it would be preferable to have a library of user by indicator events that must be updated or that a single UI update of the user and then event pass a cluster as the message that contains the name of the control for the update (to use with a structure of matter), then the data to go with it?

  Thank you!

  Instead of having the events to record in the 'create' methods, you could be part outside your 'create' SubVIs and then simply bundle them. Then, you create your individual event of the user management. See excerpt where I created a vi 'Create user event - Update' in front of the stop.

  

• Slow response from the user interface with acquisition of data of type long time

  Hi all

  I have a question to ask more out of curiosity than necessity right now. I've built a program that acquires data from the accelerometer and the Treaty in a number of ways: filtering, FFT, FRFS, things like that, but the answer of the UI is still slow, because I need a resolution of frequency of 0.2 Hz for my data domain, which means that the sample acquisition time is 5s and all this awaits before execution.

  My question is this: is there a way to completely isolate the user interface of data acquisition so that it responds immediately?

  I tried a design model of producer consumer with queues, but found everything to be always waiting for samples to be taken. Maybe it was exactly as I did.

  Thank you

  Phil

  If you need to sample for 5 seconds in order to have enough data to analyze, so unless you can "predict the future" and "knowing" the five seconds of data, simply wait for the data that arrives.  Using parallel loops of producer-consumer will allow data acquisition to proceed (for the next 5 seconds of data) while you do the analysis, but you still have to wait for the data to be analyzed.

  Note that the previous paragraph assumes you are collecting data in 5 seconds 'chunks' and analyze each "chunk" (independent) on arrival.  You could also do something like having a "second 5 sliding window" which moves, say, a second at a time, giving your FFT a finer resolution of 'time' (at the expense of their independence).  This would be a (slight) change in your loop of producer (you want to taste in 1 second pieces, accumulate 5 these pieces) and the consumption loop (start analyzing, spewing a FFT every second, while replacing the older "chunk" with the most recent - a queue with loss can do for you).

  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.

• 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/...

          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.

• Need help with this code to update the user interface example

  I'm triying to understand the differences between the three methods to manage UI interactions.
  I'm really confused with these three terms when triying them figure out in a real case.
  Basically, I know that I should use invokeLater, invokeAndWat, or getEventLock() to avoid
  This exception: java.lang.illegalStateException: engine access UI without holding the lock on the event

  The code below illustrates the function of the invokeAndWait method, but if I replace it with
  invokeLater or getEventLock() the program will work exactly the same way.
  Could you please change the code to show the differences between the three
  methods of updating the user interface?

  / public final class HelloWorldMainScreen extends form {}

  private LabelField labelField;
  public HelloWorldMainScreen() {}
  labelField = new LabelField ("Hello World");
  Add (labelField);
  Thread MainScreenUpdaterThread = new MainScreenUpdaterThread (this);
  thread. Start();
  }

  {} public void appendLabelText (String text)
  labelField.setText(labelField.getText()+"\n"+text);
  }

  }

  SerializableAttribute public class MainScreenUpdaterThread extends Thread {}
  HelloWorldMainScreen screen;

  public MainScreenUpdaterThread (screen HelloWorldMainScreen) {}
  this.mainScreen = screen;
  }

  public void run() {}
  for (int i = 0; i)< 10;="" i++)="">
  try {}
  Thread.Sleep (5000);
  } catch (InterruptedException ex) {};
  UiApplication.getUiApplication () .invokeAndWait (new Runnable() {}
  public void run() {}
  mainScreen.appendLabelText ("Update");
  }
  });

  }
  }
  }

  These three concepts are very confusing for a lot from people so all explanatory source code
  describing their functions will be highly useful for everyone, I think.

  Thanks in advance!

  With respect to the effect, there is no difference between methods.  The difference is the way in which the result is achieved.  So we can't change the code to show you the difference.

  As we are unable to demonstrate the difference, you have to do with an explanation.  To understand the explanation, you'll need to understand the thread of events, so if you have not already, please consider this:

  http://supportforums.BlackBerry.com/T5/Java-development/what-is-the-event-thread/Ta-p/446865

  If the three options are differentiated by the processing order:

  (a) invokeLater executes the update on the thread of events.  The transformation takes place at a later stage and the code which is in order after the invokeLater will actually run before the code within the invokeLater.

  (b) invokeAndWait also manages the update on the thread of events, which means that all other events that await on the thread of events will be run before this code.  But any code after the invokeAndWait will not be executed.

  (c) the synchronized option, like invokeAndWait, runs the update of the UI before moving on to the following code.  The difference is that the code to run on the event Thread is not executed before code in the synchronized block.

  If this is meaningless, so that probably does not matter too much.  in general, you should use invokeLater, except if you need to update the user interface occur in the order with your background processing.  If so, use invokeAndWait. It has synced are very few occasions where you must use the block, and it should be very small updates to the user interface and you should understand the implications this could have on the wire events.
