  The correct syntax for PORCEDURE4 is:

  It is clear that you are interested in reading the documentation. All the answers are there.

  You're mixing two things:

  How can I do this?

  For classified call a function from another ClassB (or instance of it) he should be aware of two facts: 1) that ClassB exists and 2) that ClassB has a special function.

  Another approach might be to establish a communication between classes by the events.

  You explanation, it is not clear what you want to accomplish. Do you need to call a function on the class itself or by an instance of this class?

  So old - you must create a static function and just call it:

  inside ClassB:

  public static void classBFunction()

  ClassA can call it:

  ClassB.classBFunction)

  If you call the function on an instance - you, of course, need to instantiate the class and then call the function.

  Say you have inside ClassB

  public void classBAnotherFunction() - Note that there is no static Word

  There is an other fork here: either you instantiate the ClassB inside the ClassA or you pass a reference to the instance of ClassB in ClassA

• Simple enough, but calling one method from another class

  Hi all
  I know it's pretty simple, even though I do not see where I am going wrong for some reason any. Basically, I have a class that extends JPanel but when I try to call one of its methods in my main class I get an error. The code (I hope) is:
  
  Main.Java

  import java.awt.BorderLayout;
  // ...
  import javax.swing.UIManager;
  
  public class Main extends JFrame implements ActionListener {
  
       JFrame frame;
       public static JPanel statusBar;
  
       public Main() {
  
            // ...
  
            // Add a status bar
            statusBar = new StatusBar();
            mainPanel.add( statusBar, BorderLayout.SOUTH );
  
            setContentPane( mainPanel );
            // ...
       }
  
       // ...
  
       public static void setStatusBarText( String s ) {
            statusBar.setStatusText("Test");
       }
  
       // ...
  }

  StatusBar.java

  import java.awt.Color;
  // ...
  import javax.swing.SwingConstants;
  
  public class StatusBar extends JPanel {
  
       private int barWidth;
       private static JLabel status;
  
       public StatusBar() {
            super();
            //barWidth = Main.getProgramWidth();
            //setPreferredSize( new Dimension(barWidth,22) );
            setLayout( new FlowLayout( FlowLayout.LEADING ) );
            setBorder( BorderFactory.createMatteBorder(1, 0, 0, 0, new Color(160,160,160) ) );
  
            status = new JLabel("Test", SwingConstants.LEFT);
            //status.setVerticalAlignment( SwingConstants.CENTER );
            add( status );
       }
  
       protected void setStatusText( String s ) {
            status.setText( s );
            revalidate();
       }
  }

  The "statusBar.setStatusText ("Test")"; call in the main class file does not work and I get the error:
  
  >
  cannot find symbol
  symbol: setStatusText (java.lang.String) method
  Location: class javax.swing.JPanel
  statusBar.setStatusText ("Test");
  >
  
  Any ideas what I am doing wrong? I created an instance of the class called status bar StatusBar, can I use it to call the setStatusText() method (via statusBar.setStatusText ()) I thought everything is OK, then it does not work? Even if there is an easier way to do what I want to achieve (i.e. to update a JLabel since the 'central' main class file instead of setting the JLabel static and have all classes call him directly), I'd be glad to know where I am going wrong here nevertheless.
  
  Thank you very much
  Tristan

       public static JPanel statusBar;
  
       public static void setStatusBarText( String s ) {
            statusBar.setStatusText("Test");
       }
  

  >

  symbol: setStatusText (java.lang.String) method

  statusBar.setStatusText ("Test");
  >

  The type of variable statusBar is JPanel. That's all the compiler takes into account. It is not relevant that at a certain point in the program, the type of the object pointed to by this variable is a subclass of JPanel (because at another time, it might be an instance of another subclass or JPanel itself.

• Preserve class Runtime - why?

  LV2013.

  This code works, but I'm trying to understand why I need the operation of preserve.

  If I don't get that, I get a compile error in the ShiftReg on the right:

  "One or more of the entries to this terminal registry or shift comes dynamic no frontal entry terminal."

  

  The VI used, looks like this:

  

  I have a root called "Addon" class and a class called "Addon for TC programs.

  Another class of root is called "Bench shows" - not a child of one or the other.

  "Addon for TC programming" class contains an array of "Bench Emissions" are

  The purple screws are the ADDON (root) class methods.

  So I look for each bench, do some work on it and put it back into the table.

  Some of this work is to a root method.

  But I do not understand the error.  It is impossible for the connector must be one class other than class who came out.

  If I put the turf inside the VI itself - operation there always the error.

  I can't do this second terminal DYNAMIC of entry (LV doesn't let me) - that is the question?

  Can someone walk me through what the compiler?

  The problem is not due to the static nature or dynamics of the terminal Addons, it related to the dynamic state of the seizure of the bench shows.  Because THESE entries are dynamic, LV CANNOT guarantee that the code you currently see is even the code that will be executed at run time.  Therefore, it does not guarantee that the type is preserved.

  If you wrap the "Emissions bench: bench Menu Items" VI in a static VI (who calls the dynamic VI) you can then put the preserve in the Subvi.  This will then give the appearance of the double dispatch.

• Problem with the combination of LabVIEW (dynamic distribution) classes, statechart module and module FPGA

  LOCATION:

  -I am developing a software plugin based on plug-ins based on LabVIEW classes that are instantiated in running. Plugin real classes come from the plug in generic classes that define interfaces to the VI instantiation and can provide basic functionality. This means that many of the methods of the class are dynamic distribution and even methods of child classes can call the parent method.

  -Plugins top level (the ones directly accessible by the main VI) each have a run method that animates a plug-in specific state transitions.

  -Transitions of the plug-in data acquisition (DAQ class) class calls a method of the DAQ class that reads data from an FPGA card OR and transmits to another component via a queue.

  PROBLEM:

  -Higher sampling rate, a FPGA-to-host FIFO overflow occurs after some time. When I "weigh" the system just by moving a window of Firefox browser on the screen, the overflow is triggered immediately. I did not have this kind of problem in older software, where I was also reading a FIFO of FPGA, but made no use of LabVIEW classes or diagrams.

  SOLUTIONS I'VE TRIED (WITHOUT SUCCESS):

  -J' put the transitions in a timed (instead of a simple while loop) loop that I assigned specifically to an own kernel (I have a quad-core processor), while I left all the other loops of my app (there many of them) in any simple loops. FIFO overflow still occurs, however.

  QUESTION:

  -Does anyone have a tip how I could fix this problem? What could be the cause: dynamic distribution methods, the acquisition of data of state transitions or just the fact that I have a large number of loops? However, I cannot change the fact that I have dynamic distribution methods because it is the essence of my architecture...

  Tips are greatly appreciated!

  I've now changed the execution priority of all the screws involved in reading of the FPGA FIFO '(highest) priority critical time '. This seems to be improving the situation much: so far I have not a FIFO overflow, even when I move around the windows on the screen. I hope it stays like that...

• Confused about the use of accessors with classes.

  With a new assignment thought, it would be appropriate to increase the use of labview OO features. In my case, I'm trying to use a class to contain a bunch of different calculations. The calculations require multiple entries to finish so I built a control to take care of these data. My plan was to build separate methods for each calculation. This will allow to easily add new calculations and considering that many calculations depend on preliminary calculations seem to be an excellent opportunity to learn a new part of labview.

  My problem is to find an elegant way to complete this great control; I believe that I must write accessor vi to allow outside access to the objects. I don't know if there should be one vi for EACH parameter accessor, or if I can access these items in a cluster.

  I can only relate to the use of get / set in .NET and usually I would write one for each variable that I have access to. I'm not sure how to proceed in LabView. Any ideas would be great.

  I enclose a few images. One showing just a sumple calculation and one of my ctl. Still, my main question is what is the best way to populate the items in this list.

  -Chris

  Since there is no such thing in LVOOP as public members of class (and thank God / NOR) you must always provide accessors (getters/setters) to join the data members of the class outside of the classroom.

  Inside the method of class VI, there is no need for them since you can reach directly from the wire with bundle/unbundle (like photos).

  I've implemented a similar class that performs calculations and I chose to use the recursive calls to deal with the problem of some variables must be calculated before the others.

  I'm a member of the VI class called GetCalculatedVariable.vi which takes the name of the variable to calculate input (like typedefed enum).
  Inside of this VI have a structure dealing with a box for each variable that can be calculated.

  The inside of the box, I define the calculation, and if I ever need another variable, I here call GetCalculatedVariable.vi recursively.

  In addition, I also have a CalcBuffer so I don't have to call GetCalculatedVariable.vi more than once for each variable.

  The class also has a GetMeasuredVariable.vi which also uses the recursion in the same way, but works on my measurement files instead.

  The advantage is that my application code gets very clean because it contains only a single Subvi callto obtain and use any calculated variable.

  I also have a GetCalculatedVariables that takes an VariableNames array and returns an array of values.

  I hope this helps...

• Determine the name of class LVOOP? d ' a class of child...

  Hello

  I have a number of modules (classes) that inherit from a base class called "Module".  I have all these in an array of type 'Module', I would like to save some information of each of these modules, but I need to make the distinction between each module.

  Is there a way to determine the class name of the data cable?

  Can I use the flattened string Variant, but I was wondering if it had built in property for this node/function?

  Thank you
  Jonathan

  Examples of joint:

  

  

  

  Malkieri,

  There is no generation in function that does exactly what you are looking for, but you can use the 'Get LV class Path' VI to return the *.lvclass of an object path given.  Using this way, you can either parse the name, or you can use Server VI to get the name of the class, as shown in the picture as an attachment.

• Use a typedef in a class?

  Hello.  I work on an OSGA application to communicate with the ANT +.  I am currently working on the message of ANT factory and I have a question about the typedefs.  I want to give the user the option of selecting a ring of text of a message to send to the device.  My research on this Web site discovered so far plans to be completed by programming the 'strings []' property of the ring of text and load classes dynamically.  I also found a way to use variants as lookup tables (that is, dictionaries are used in Python).  This is great and allows me to add new classes to the application simply by creating a new child class and adding his (name, path) pair in a file.  I use a ring typedef text to store the values of message names that the user can select.  My question is, can / should I keep this typedef in a class?  Some research has found that the classes are considered to have eliminated the need for typedefs in many cases, so I suspect that I might be missing something.  I have attached the VI message factory.  Not that this will make a lot of sense without its dependencies, but maybe this will help show my thought process.

  I also wonder what class to store the typedef in.  I have a message class (called "ANT_Command") as well as a device class and a class session.  My gut says to put in the class of sessions, but the device class can be a better place for this.  I suppose it could also live in the superclass message...

  Any comments would be appreciated

  Thank you

  -Jamie

  But values and associated channels are NOT stored in the typedef information, having thus a typedef ring just makes no sense.

  Update the typedef of a ring to include different channels will NOT update all controls bound to this typedef because the strings are NOT part of the data type.  With an ENUM, the ropes ARE part of the data type and so are spread with each change in control typedef.

  localStorage.setItem("save", test);
  var test2 = localStorage.getItem("save");
  

  I have my own class called Foo and I save and load. I wanted then the same test and test2.

  but when I load the stuff in test2 is not something more. How to achieve this?

  Hello

  localStorage can save only the name/value pairs; essentially, the strings. You cannot save complete objects in this storage.

  https://developer.BlackBerry.com/HTML5/APIs/localStorage.html

  It is where IndexedDB would come in, but for now was not implemented on the platform.

  The solution here would be to save the table in localStorage as strings, potentially even with toString to avoid creating multiple entries:

  Then, when you want to create your table test2 , you must read this entry, analyzed and complete your table by program rather that expecting to be created directly by calling getItem . To the stage of the analysis, you can use something like split.

• 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.
