• How to upgrade the style sheets when running?

  Strangely the style does'nt changes if I manually change the rules of css class in one of the css document and switch between the 2 files.

  @Override

  Public Sub initialize (URL url, rb ResourceBundle) {}

  final String cssUrl1 = getClass().getResource("/tracker/view/fxmlgui1.css").toExternalForm ();

  final String cssUrl2 = getClass().getResource("/tracker/view/fxmlgui2.css").toExternalForm ();

  rootPane.getStylesheets () .add (cssUrl1);

  rootPane.addEventHandler (KeyEvent.KEY_PRESSED, new EventHandler < KeyEvent > () {}

  @Override

  {} public void handle (KeyEvent keyEvent)

  If (keyEvent.getCode () .equals (KeyCode.DIGIT1)) {}

  rootPane.getStylesheets () .clear ();

  rootPane.getStylesheets () .add (cssUrl1);

  msgLabel.setText ("Css1 selected.");

  } ElseIf (keyEvent.getCode () .equals (KeyCode.DIGIT2)) {}

  rootPane.getStylesheets () .clear ();

  rootPane.getStylesheets () .add (cssUrl2);

  msgLabel.setText ("Css2 selected.");

  }

  }

  });

  }

  The event occurs and the style change of css1 and css2, as it was at the scene is rendered, but if I change one of the rules in the sylesheets after step is planned, the does'nt lifestyle changes more.

  So who is the General method to change the style of nodes change the css document at run time?

  It's like the original stylesheets in css documents someway implemented cache and does'nt update to any switch.

  Is the purpose of being able to edit the css file, and then press a key or press a button "recharge style" on the user interface and see the models updated? I don't think that's really the purpose of the css style: intent is really that the css file that will be provided in the your application jar file and never even extracted, both and edited and reloaded. (It can even be converted to a binary format that is faster to load).

  That said, however, the following works fine for me. (JDK 1.7.0_25, JavaFX 2.2.25). Run the application, you see the label in blue. Edit the css and save (without leaving the app), press the button reload the style, and you see all changes take effect. Who does not work for you?

  import javafx.application.Application;
  import javafx.event.ActionEvent;
  import javafx.event.EventHandler;
  import javafx.scene.Parent;
  import javafx.scene.Scene;
  import javafx.scene.control.Button;
  import javafx.scene.control.Label;
  import javafx.scene.layout.VBox;

  public class CssReloader extends Application {
  
   @Override
    public void start(Stage primaryStage) {
    final VBox root = new VBox(5);
    final Button reloadButton = new Button("Reload style");
    reloadButton.setOnAction(new EventHandler() {
              @Override
              public void handle(ActionEvent event) {
                  loadStyle(root);
              }
          });
    final Label label = new Label("A message");
    root.getChildren().addAll(reloadButton, label);
    loadStyle(root);
    primaryStage.setScene(new Scene(root, 300, 150));
    primaryStage.show();
    }
  
    private void loadStyle(Parent node) {
        node.getStylesheets().clear();
        node.getStylesheets().add(getClass().getResource("editMe.css").toExternalForm());
    }
  
    public static void main(String[] args) {
    launch(args);
    }
  }
  

  editMe.css:

  
  @CHARSET "UTF-8";
  .label {
   -fx-text-fill: blue ;
  }
  

  Update: of course, this code will not work if you combine this as a jar file and run it from there. getClass () .getResource (name) produces a URL that represents a resource loaded from the same location as the class underway (in this case the jar file), and toExternalForm() that allows to convert to a string. Of course to edit a css won't help in the bundled jar file. (Try to view as follows. Launched from a file system class loader, you will get a file:// url; launched from a jar class loader, you will get a pot: / / class loader.)

  private void loadStyle(Parent node) {
        node.getStylesheets().clear();
       String resource = getClass().getResource("editMe.css").toExternalForm() ;
       System.out.println(resource);
        node.getStylesheets().add(resource);
    }
  

  To force a system file URL, even if you run from a jar file, you can do this:

  privatevoid loadStyle(Parent node) {
        node.getStylesheets().clear();
        try {
              final String resource = Paths.get("/path/to/editMe.css").toUri().toURL().toExternalForm();
              System.out.println(resource);
              node.getStylesheets().add(resource);
          } catch (MalformedURLException e) {
              e.printStackTrace();
          }
    }
  

  Now, of course you have something of a headache of deployment; you will need to make sure somehow that there is a css file in the correct location - outside packaging jar - as part of the deployment of your application. You can check for its existence at startup, and if she's not here read a default version of your jar file and write it in the location in which you expect to find; or find another strategy.

• How to upgrade the enum labels when enum is inside an array of clusters?

  Hello gurus of LabVIEW,.

  I'm stuck with one aspect of the design and I was wondering if you could share some ideas on how to move beyond this: I want to fill an array of strings, and then complete an enum inside a table with string values.

  For the purposes of discussion, I'll break you in two actions steps, where it takes place before the second (sequential, not in parallel)

  Action - the user will first ask you to fill a table with 'strings '. The table might look like,

  row0 - "string0".

  Row1 - 'string1 '.

  row2 - "word2".

  and so on...

  Action 2 - whenever the user "action selects two" I would like to fill out an ENUM inside a cluster with the values of 'Action '. In other words, I am trying to dynamically write enum values.

  The cluster has several objects such as Boolean controls, String, control, AND YEAR ENUM (see attachment .png)

  I tried using the ring and enumerations at this stage and have failed him. I read somewhere that the enum/ring is in a cluster and the cluster within a table, what I'm trying to do is simply not possible. If this is the case, can you please throw my ideas, my ideas? :-)

  In advance, thank you very much.

  See you soon,.

  First of all, the question is your cluster is a strict type def and preventing you from updating the ropes of the ring then I turned into a normal type def.  I've also got rid of the sequence and the while loop they were not useful anyway.  Just unzip and run the VI then enter values in the table, as you enter data, that the ring is updated with the new value.

• How to disable the button submit when running

  Hello
  
  I create a page with buttons createEmployee, deleteEmployee and updateEmployee employee management.
  
  I want to disable the buttons send above if the user is "OPERATIONS".
  
  My code as follows:
  
  String userName = pageContext.getUserName ();
  
  {if ('Operations'. Equals (username))}
  OAPageLayoutBean page = pageContext.getPageLayoutBean ();
  page.prepareForRendering (pageContext);
  OAGlobalButtonBarBean buttons = (OAGlobalButtonBarBean) page.getGlobalButtons ();
  OAGlobalButtonBean button = (OAGlobalButtonBean) buttons.findIndexedChildRecursive ("CreateEmployeeButton");
  button.setDisabled (true);
  }
  
  but he throws NullPointerException.
  
  For this code, I guide the OAF Dev R12.
  
  can you explain what is function_name in the next line
  
  Button OAGlobalButtonBean = (OAGlobalButtonBean) buttons.findIndexedChildRecursive ("< function_name >");
  
  I tried with the id of the button, but I didn't work.
  
  Can you explain about this clearly.
  
  Thanks in advance,
  SAN

  Hello

  I think that your button on the page is in the region of pageButtonBar.

  Use code below.

  String userName =pageContext.getUserName();
  
  if("OPERATIONS".equals(userName)){
  OASubmitButtonBean button = (OASubmitButtonBean) webBean.findChildRecursive("CreateEmployeeButton");
  if(button!=null)
  {
      button.setDisabled(true);
  }
  }

  You can try Capabilities.version. I used it to make the distinction between IOS and Android, and you can probably find Windows or Mac from that, too.

• Help!  How to upgrade two dimension collection ArrayCollection?

  Hello
  
  I'm having a problem of understanding of documentation on populating a DataGrid of two dimension collection ArrayCollection. My situation is that I have a DataGrid with a bunch of information, currently stored in a two-dimensional array (digital in the first dimension and by field name in the second dimension). I also have a bunch of data streaming from an XMLSocket, which, when it happens, is analyzed, resulting in one of the fields of the table in need of update. I can do very well with the table directly, but I can't try to understand how use the ArrayCollection collection features to cross this two-dimensional structure - setItemAt() does not seem suited for this purpose? I need to trigger the effects on the relevant cell that has been updated, when I round coding, so I will try to use some structure that handles update events and others for me automatically, such as the ArrayCollection collection.
  
  I do not know is still the best technique to use, and the intermediate level (the ArrayCollection collection and others) could be changed completely, so if you can suggest (and illustrate, if she is as confused as this!) a better method, I would be grateful.
  
  Thank you
  
  David
  

  Ah.

  You must look for the item in the collection ArrayCollection. This is usually done with a loop in the collection. When you have found the item you would:

  Item.Quantity = new quantity;
  dp.itemUpdated (item);

  You must call the method of collection itemUpdated to make the signal Collection all interested parties (for example, the DataGrid bound to her) she's changed.

  A Collection can also views and ViewCursors that might be useful to have a lot of data.

• How to check whether or not the arraycollection collection is initialized

  Hi all

  I am bit new to use the collection arraycollection in flex. I'm having this particular scenario, where I get Server data in a table. So I have to check if the arracollection I created is initialized or not. If it is not initialized I need to initialize it or other wise, just add collection from table to table. Here is the code snippet

  currentTrajectory = new collection ArrayCollection (event.result as Array);

  var _multiTrajectoryEvent:MultiTrajectoriesEvent;

  _multiTrajectoryEvent = new MultiTrajectoriesEvent (MultiTrajectoriesEvent.DRAW_AUTO_TRAJ);

  If (!) (_multiTrajectoryEvent.trajectories.source is nothing))

  {

  _multiTrajectoryEvent.trajectories.addItem (currentTrajectory);

  }

  else

  {

  _multiTrajectoryEvent.trajectories = new ArrayCollection ([currentTrajectory]);

  }

  But unfortunately the above code does not work for me, because the arraycollection collection is not initialized first, there is no way of checking me if it is initialized later or not as the compiler gives me the error checking to null...

  Can any Walter suggest how can I check if the table collection is initialized or not?

  I would appreciate any suggestions and thouhgts for the same

  Thank you

  Akshay

  Sorry to say, but it's not the right approach...

  I'm abt don't know what is exactly done so I'll give a generic example...

  I have an ArrayCollection collection...

  private var arrC:ArrayCollection;

  Maybe it's getting used internally in several places, so you be sure if she be initialized already or not. Then use a code something like that...

  If (arrC! = null & arrC.length > 0)

  {

  ...

  ...

  }

  If you are using

  If (arrC.Length > 0)

  {

  ...

  ...

  }

  and it is not initialised it will give exceptional at the time to compile...

  For a logic if(a && b) be true both a and b must be true, so if same first one (a) is false it will not evaluate the second logic (b).

  Thus, the previous logic works.

• How to access the Flex collection ArrayCollection in Action Script components?

• How to upgrade the Switch application icon

  Hello

  I'm working on a UiApplication in Java that runs in the background all the time.  I need support the 7290, some 8,000 s and the "BOLD".  The screen resolution is very different between the 7290 and "BOLD" and the icon that looks good on the 7290 seems jerky on the "BOLD". And the icon that seems good on the "BOLD" is not full screen on the 7290, and we know, that there is a problem.  So, I followed the information contained in these two links to update my icon based on that screen resolution that we, to make my icon looks good no matter what device has a user.

  BB in Knowledge Center article - how to set an icon of overview

  BB Forum of Discussion on the overview icon

  Now on the 7290, I use an icon of size 32 x 32 pixels and on the "BOLD", I use an icon of size 64 x 64 pixels.  I know that 64 x 64 is not the recommended size for the "BOLD"... and it looks better for what I do.

  OK, so to enter some details, I have a main entry point, which has an icon associated with it (which is the icon that I have 'default', you can tell).  And it's the icon of my startup code updates (via HomeScreen.updateIcon (getHomeScreenIcon (), 0) and is what you see in the Applications folder (or on the main Menu, depending on what device, of course).)  And on the menu, when you click this icon, it brings my application in the foreground and here we go. It works just as advertised and is great.  I have the icon on the right showing on the right screen resolutions.  No problem.

  Is then where I run into trouble.  I have another point of entry, who calls my startup code and gets my application running in the background.  It has an associated icon also (once again just the icon I want 'default' before I can get the Update icon.  It is the icon that can be found on the Ribbon for switching applications (when the user presses ctrl-esc).

  And once again, in my startup code, I try to use - HomeScreen.updateIcon (getHomeScreenIcon (), 3); -Please note the different entry point number that corresponds to this entry point.  I checked the CAP file to determine the correct entry point number and this update still does not take effect.  I also tried each number from 1 to 5, no chance.  I can't get this icon to update.

  How to upgrade the icon that appears on the Ribbon for switching applications?  And if I can't be updated for a reason, how can I specify a different icon for different screen resolutions?

  Thank you, Tara

  PS. I use JDE 4.1.0.185, simulators and devices of 7290, 8100, 8300, 9000 (Bold).

  The issue of the HomeScreen.updateIcon do not update the icon displayed in the application of task switch has been resolved in BlackBerry handheld software version 4.7.0.  The only work-around from earlier versions is to have several versions of the application that are built with different application icons.

• Is it possible to search the ArrayCollection collection by index?

  Hi all

  I know, we can loop and compare each element of the ArrayCollection collection to get the correct item that we want. Obveriously, performance is going to hurt and it is not a wise method of search. Can we create an index for the key field of each item? Or any other class offering such a feature?

  Thank you

  When you say "a clue" are you talking like one in a table of database index?  That is something that can speed up a search?

  I'm trying to understand your desire and I think that what I hear, is that you have an ArrayCollection collection contains a number of objects.   When you want to find a particular object, you have found a way to locate the desired instance to browse each item in the collection ArrayCollection and ask "this element is equal to the key of the object I'm looking for?   I think that you are concerned by the amount of time it can take.

  Go back decades to my knowledge of computer science, this is an o(n) algorithm where n is the number of items in the table.

  Now, if there was an 'index' (ala databases) on the data, so if this index have been sorted, you would be able to find your match in O (log n)

  You can pay an O (n log n) cost the sort index when the data structure is created, but if you have a large number of research, then it can pay for itself.

  I'm not aware of any function that will help you on this out of the box (but that doesn't mean not there does not exist, only that I don't know about it.)

  I would like to also truthly ask yourself "is it worth the cost?   How many items you will have a typical table?  How often do you locate an entry in this table?

• Refresh the ArrayCollection collection

  How to refresh an ArrayCollection collection? My table shows the correct data at the start to the top, but will not update when a value changes via a slider or a climber. I have bound value of a slider to a NumericStepper and will use the value of the stepper in the table.
  
  any help would be greatly appreciated.
  
  The following code Snip:
  
  [Bindable]
  public var fresh: ArrayCollection collection;
  
  private function init (): void
  {
  cool = new ArrayCollection([)
  
  {FixedValue: 'Implied default rate', result: 15.80, expenses: (stepper.value-stepper2.value)/stepper0.value*(100)}
  

  I think you need to listen the NumericStepper change event and fill the value in the table in this eventhandler.

  I have an arrayCollection collection each time it updates, I need to make some sort of a calculation, how can I do with mechanizm binding?
  
  Thank you
  Jean Michel

  There is an event collectionChange on the ArrayCollection collection that gets shot above power off when the ArrayCollection collection changes. You can capture this event and then sort the collection out of that.
