Any way to listen for changes in Spark TextArea?

Hello,
What is the best way to listen for changes in a Spark TextArea? My scenario is simple: I need to know when some text is added or deleted (with from/to index).
Regards,
Dinko

  • Is there any way to listen for OS-commands like LINUX/UNIX "kill myApp"?

    Hello, world! ;)
    I would like to get help on the following problem:
    Situation:*
    Implementing my first server-daemon I was wondering if there is any way to listen for OS commands/events affecting the application.
    One particular handling I intend to implement is after an OS termination command (like *"kill myDaemon.jar"* on LINUX/UNIX) to shut down the daemon.
    This would be really helpful, because in this way I would not just shut down the daemon brutally but being able to handle an event like this to shutdown the Thread pool, send all connected peers that the server/daemon will be down for a while, close all connections ...
    Need help:*
    Am I completely forgetting something which solves this problem really quick? :D
    Is there any Listener Interface which I can use to achieve this?
    Is maybe the JVM/JRE handling this and running garbage collectors?
    Is there any site/tutorial/... focusing on problems like this?
    Thanks in advance for any help on this subject!

    Thanks, this was indeed very helpful.
    I implemented a shutdownHook and it works like I hoped it would:
        Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
          @Override public void run() {
            // shut down commands
        }));After typing *"kill process_ID"* in a terminal the shutdownHook is invoked (like mentioned before) and the shut down commands are executed.
    Works fine.
    Am happy. :D

  • Is there any way to register for changes in a NetworkInterface?

    Greetings. I'm interested to know if there's a way to register for changes to a NetworkInterface. Changes could include ifup/ifdown, a change in the displayable name, adding/removing InterfaceAddress or InetAddress, or even a change in the hardware address. It doesn't look like it but I thought I'd check.
    Thanks. Jerry.

  • Way to listen for change in JTable cell?

    I am having troubles trying to catch a key event while the user is entering text inside a given JTable cell (x/y location). The JTable only seems to manage String objects in it's cells so I can't place a JTextField in there with a KeyListener on it.
    Currently, I can only get control of the application once the user has left the cell they are editing.
    Does anyone have an example of a JTable 'cell KeyListener' scenario? At this point I want to see if I can print 'hello world' each time I type a character within a cell. Then I'll go from there....

    If you want to know when the contents of a cell have been updated you should use a TableModelListener.
    If you want to know when a character is added/removed from the cell editor then you need to first understand how this works with a simple text field.
    Typically you would use a DocumentListener to receive notifies of a change to the text field. However, within the DocumentEvent you wouldn't be able to change the text field as this notification comes after the text field has already been updated.
    If you need to ability to intercept changes to the text field before they happen, then you would need to use a DocumentFilter. An example of using a DocumentFilter is given in the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html#filter]Text Component Features.
    Once you get your regular text field working the way you want, the next step to create a DefaultCellEditor using this JTextField and use this editor in your JTable. The above tutorial also has a section on using editors in a table.

  • How do I listen for changes in a container's components?

    I have a JScrollPane that contains a JTextPane. I want any Container that can possibly contain my JScrollPane to be able to listen for changes in the JTextPane's Document.
    For example, at the moment I'm using a JTabbedPane to hold a number of my JScrollPanes and I want to alter the tab title when any associated JScrollPane-JTextPane-Document is updated.
    Any suggestions on how best to handle this?

    I would use a controller object that manages all your gui components (tabs, scrolls, documents, text panes). Your controller object can register as a listener to the appropriate component, and when it changes, update the title of a tab (or do whatever else) as appropriate.
    Never put business logic like this stuff inside the actual gui components. Create, layout, etc. all the gui components (and related components like Document) from another controller like object instead. It makes handling the various listener stuff like this much easier. Read up on MVC (model view controller) stuff for more info.
    As for the actual mechanics, you could get the document that is used in the JTextPane and register as a DocumentListener. As a document listener, you get notified of all changes that are made to that document.

  • Is there any way to search for a term using the Firefox search field, and have the results automatically open in a new tab?

    Is there any way to search for a term using the Firefox search field, and have the results automatically open in a new tab? When there was support for Google Toolbar, I was able to do this; now, whenever I want to search for something, I have to open a new tab to do it, and cut-and-paste my search into the search field in the new tab. I used to be able to highlight, drag, and drop something into the search field and have it automatically open in a new tab. This is enough for me to switch to Chrome . . .

    Set a preference to have searches from the Search Bar (upper right) automatically open all searches in a new tab
    #type '''about:config''' in the URL/Location/Address bar and press the Enter key
    #if you see a warning, accept it (promise to be careful)
    #Filter = '''browser.search.openintab'''
    #in the lower panel, double click the item (or right-click and choose "Toggle") to change the value to "true"
    #close the about:config tab and test

    About Google toolbar............
    Google decided that they will no longer produce the Google Toolbar for Firefox 5 and newer version. It is best to move on to other alternatives than to try any "hacks" to the toolbar that may or may not perform in the future. Future versions of Google toolbar will only work with IE7-9. Google Toolbar is not available on any other browser, even Google's own browser.

  • How do I listen for change in the global position of a Node

    Hi there,
    I want to create a Wire/Connection node between two scene nodes. I want this Wire node to be updated when one of the nodes is moving. In the common scenario I would listen for change events in the target nodes position and update the Wire :
    targetNode1.translateXProperty().addListener(new ChangeListener<Number>() {
    public void changed(ObservableValue value, Number oldValue, Number newValue) {             
    wire.setStartX(targetNode1.getTranslateX());
    wire.setStartX(targetNode1.getTranslateY());
    wire.setEndX(targetNode2.getTranslateX());
    wire.setEndY(targetNode2.getTranslateY());
    The problem is that the target nodes are children of another container nodes(that are actually moving). So listening for change events in the translate properties of the target nodes does not work(their parent nodes are actually moving)
    Is there way to listent for change in the global position of the target nodes relative to the Scene?

    It sounds very similar to a problem I posted about earlier...
    How to implement a UI similar to a UML Diagram with connections?
    I ended up making my own special bounds property, that updates when the parent's special bounds property changes.
    I also had to listen to the parentProperty change event to add/remove my listener on the parent node.
    All in all, a pain in the butt. There should be an easier way.
    The shortcoming of the solution is that all the nodes in the hierarchy must have my special bounds property implemented (ie. they're all classes under my codebase such that I can implement it), which for the moment is true... I'd like a cleaner solution however.

  • Is there any way to block PR changes when PO exists in project builder

    Dear All,
    Could you please advice...is there any way to block PR changes (quantity,price, etc) when PO exists in project builder ?

    Hi Nies,
    If you are not using the material then you can go for Validation, under Operative Structure> Network> Validation.
    Attach the validation with OPSA click on Automatic.
    In the second scenario if you are using Material Component, as Mr.Muralidharan said OPSG there you can restrict the change by selecting Error Message.
    1. Tcode OPSG in Setting see all the object are selected.
    2. Click on Component tab under change in Purchase Order Exist tab select Error.

  • Is there any way to control or change the email notification format deliver

    Hi,
    Is there any way to control or change the email notification format delivered by iBots? I have created an iBot to deliver the scorecard report to the team with type chosen as 'Attachment (HTML)' option. With this definition of iBot - notification being sent in MIME HTML (.mht) format. Due to some security settings at my email client - the attachement gets quratined because of .mht format. So, I am looking for an option to send the notification only in HTML (.htm) format with which I don't have any issues with my email client?
    Any help is really appreciated.
    Thanks,

    Why do Orange and EE blame Apple for the delays in unlocking my iPhone. 10 months now. What is the exact process that these companies have to go through to unlock an iPhone and is Apple in any way to blame for the delays.
    Indeed how long does Apple take to carry out its part of the process. 
    It seems to me that Orange are just trying to stall me despite the fact that I am out of contract with them now.  I originally paid to have the phone unlocked back last November.  This was never done. 
    I have phoned them numerous times over the last two months but still they haven't done it.  Can anyone advise me and has anyone had similar problems with them.
    Thanks

    I certainly understand that only Orange can unlock my phone.  My annoyance is that they blame Apple so I am keen to know what exactly is Apple's involvement. 
    I presume that Orange have to tell Apple that the phone has been authorised for unlocking by Orange and that Apple then notes that in some way on iTunes so that the user can then complete the process on iTunes. 
    What I would like to know is how much time Apples part in this process takes.
    I would also like to make contact with others who have had similar problems.
    Many thanks

  • Any way to search for transparent items?

    Is there any way to search for items that have an opacity of less than 100%?  I found that some of the advertisements I placed inexplicably came in at 76% opacity.  And I noticed some tiny endmark graphics came in with 0% opacity.  I don't know why.  I'm just trying to make sure I didn't miss correcting anything.
    Thanks, Phyllis

    Err, whoops. That's not going to work, because there's not a list of images in the document, only a list by page. And it's probably better to use Graphics instead, which include, e.g., PDFs.  So you probably want instead:
    var d=app.activeDocument, im=d.allGraphics, i;
    for (i=0; i<im.length; i++) {
      if (im[i].transparencySettings.blendingSettings.opacity < 80) {
        alert("Page "+im[i].parentPage.name+" has "+
          im[i].itemLink.filePath);
    And this iterates over Graphics which are the things inside containers (like rectangles). You might have the transparency applied to the container rectangle instead, in which case you'd probably need to replace allGraphics with allPageItems, except then it would fail on all the objects that don't have a transparency property [sigh...], so you'd need something (ick) like this:
    var d=app.activeDocument, im=d.allPageItems, i;
    for (i=0; i<im.length; i++) {
      try {
       if (im[i].transparencySettings.blendingSettings.opacity < 80) {
          alert("Page "+im[i].parentPage.name+" has "+
            im[i].itemLink.filePath);
      } catch (e) { }

  • Listening for Changes to JTextArea

    I am writing a program that listens for changes to the contents of a JTextArea to obtain input for its execution. But I have implemented DocumentListener, PropertyChangeListener to listen for changes to the JTextArea for deriving input without success. Please could anyone advice on what to do.
    My code is below.
       myListener implements DocumentListener{
       JTextArea txt = new JTextArea();
       txt.getDocument().addDocumentListener(this);
