How do I use Tooltip in a thread?

Hello Everyone.
I'm trying to use Tooltip in a (added) thread, but I've got IlligalStateException.
Task task = new Task<Void>() {
    @Override
    protected Void call() throws Exception {
        Tooltip tooltip = new Tooltip();
        return null;
new Tread(task).start();NetBeans 7.1
JDK 1.6.0_30
JavaFX 2.0.1
I can use other controls (like Button, etc).
Thank you in advance.

How do I use Tooltip in a thread? You can only create Tooltips on the JavaFX Application Thread due to this bug: http://javafx-jira.kenai.com/browse/RT-17716

  • How to correctly use a fixed size thread pool?

    I am quite new to using concurrency in Java, so please forgive if this is a trivial question.
    I would like to make use of something like pool=Executors.newFixedThreadPool(n) to automatically use a fixed number of threads to process pieces of work. I understand that I can asynchronously run some Runnable by one of the threads in the threadpool using pool.execute(someRunnable).
    My problem is this: I have some fixed amount of N datastructures myDS (which are not reentrant or sharable) that get initialized at program start and which are needed by the runnables to do the work. So, what I really would like to do is that I not only reuse N threads but also N of these datastructures to do the work.
    So, lets say I want to have 10 threads, then I would want to create 10 myDS objects once and for all. Each time some work comes in, I want that work to get processed by the next free thread, using the next free datastructure. What I was wondering is if there is something in the library that lets me do the resusing of threads AND datastructures as simply as just reusing a pool of threads. Ideally, each thread would get associated with one datastructure somehow.
    Currently I use an approach where I create 10 Runnable worker objects, each with its own copy of myDS. Those worker objects get stored in an ArrayBlockingQueue of size 10. Each time some work comes in, I get the next Runner from the queue, pass it the piece of work and submit it to the thread pool.
    The tricky part is how to get the worker object back into the Queue: currently I essentially do queue.put(this) at the very end of each Runnable's run method but I am not sure if that is safe or how to do it safely.
    What are the standard patterns and library classes to use for solving this problem correctly?

    Thank you for that feedback!
    There is one issue that worries me though and I obviously do not understand it enough: as I said I hand back the Runnable to the blocking queue at the end of the Runnable.run method using queue.put(this). This is done via a static method from the main class that creates the threads and runnable objects in a main method. Originally I tried to make that method for putting back the Runnable objects serialized but that inevitably always led to a deadlock or hang condition: the method for putting back the runnable was never actually run. So I ended up doing this without serializing the put action in any way and so far it seems to work ... but is this safe?
    To reiterate: I have a static class that creates a thread pool object and a ArrayBlockingQueue queue object of runnable objects. In a loop I use queue.take() to get the next free runnable object, and pass this runnable to pool.execute. Inside the runnable, in method run, i use staticclass.putBack(this) which in turn does queue.put(therunnableigot). Can I trust that this queue.put operation, which can happen from several threads at the same time works without problem without serializing it explicitly? And why would making the staticclass.putBack method serialized cause a hang? I also tried to serialize using the queue object itself instead of the static class, by doing serialize(queue) { queue.put(therunnable) } but that also caused a hang. I have to admit that I do not understand at all why that hang occurred and if I need the serialization here or not.

  • How can I use a Selector in a thread safe way?

    Hello,
    I'm using a server socket with a java.nio.channels.Selector contemporarily by 3 different threads (this number may change in the future).
    From the javadoc: Selectors are themselves safe for use by multiple concurrent threads; their key sets, however, are not.
    Following this advise, I wrote code in this way:
             List keys = new LinkedList(); //private key list for each thread
             while (true) {
              keys.clear();
              synchronized(selector) {
                  int num = selector.select();
                  if (num == 0)
                   continue;
                  Set selectedKeys = selector.selectedKeys();
                  //I expected this code to produce disjoint key sets on each thread...
                  keys.addAll(selectedKeys);
                  selectedKeys.clear();
              Iterator it = keys.iterator();
              while (it.hasNext()) {
                  SelectionKey key = (SelectionKey) it.next();
                  if ((key.readyOps() & SelectionKey.OP_ACCEPT) == SelectionKey.OP_ACCEPT) {
                   Socket s = serverSocket.accept();
                   SocketChannel sc = s.getChannel();
                   sc.configureBlocking( false );
                   sc.register( selector, SelectionKey.OP_READ );
                  } else if ((key.readyOps() & SelectionKey.OP_READ) == SelectionKey.OP_READ) {
    //.....Unfortunately synchronizing on the selector didn't have the effect I expected. When another thread select()s, it sees the same key list as the other thread that select()ed previously. When control arrives to serverSocket.accept(), one thread goes ahead and the other two catch an IllegalBlockingModeException.
    I'm not willing to handle this exception, the right thing to do is giving disjoint key sets to each thread. How can I achieve this goal?
    Thanks in advance

    A single thread won't be enough cause after reading data from the socket I do some processing on it that may take long.So despatch that processing to a separate thread.
    Most of this processing is I/O boundI/O bound on the socket? or something else? If it's I/O bound on the socket that's even more of a reason to use a single thread.
    Anyway I think I'll use a single thread with the selector, put incoming data in a queue and let other 2 or 3 threads read from it.Precisely. Ditto outbound data.
    Thanks for your replies. But I'm still curious: why is a selector thread safe if it can't be used with multiple threads because of it's semantics?It can, but there are synchronization issues to overcome (with Selector.wakeup()), and generally the cost of solving these is much higher than the cost of a single-threaded selector solution with worker threads for the application processing.

  • How to use Wait Screen and Thread?

    Greetings,
    I was wondering If I could ask a question...
    Here it goes:
    How can I use a Wait Screen in a MIDlet so that I can do the Following:
    1.- Create and Open an Http Connection[b[i]](using an Object which extends Thread) in a Form by pressing an OKCommand.
    2 .- Show the Wait Screen Until the Thread Object finishes execution(finishes whatever is inside run() method)
    3.- Finally show the Result(s) of the Connection(bytes obtained from URL) in another Form.
    First of all, Is what I ask even possible? and more importantly...
    Can a Wait Screen actually Detect when a Thread finished execution? so that only when the thread finishes the program proceeds to the next statement?
    Thank you very much in advance!
    Sincerely, your friend,
    Jose

    Thank you very much Sir, I suppose that narrows it down a bit,
    Because I definitely need my applications as standard as possible.
    But good to know there's a way to do it.
    Well, Thank you very much as usual!
    Sincerely,
    Keep up with the fantastic job you do every day!

  • How can I use a 3rd party XML parser such as xerces with OC4J ?

    Hi all tech experts,
    I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
    installed Portal and Wireless and OracleAS Infrastructure on the same
    computer.
    i tried all the solutions on this thread
    Use of Xerces Parser in out application with Oracle App Server 9.0.4
    but still fighting.
    I have also posted this query on OTN on following thread
    How can I use a 3rd party XML parser such as xerces with OC4J?
    but no reply....
    Please help me on this issue.
    Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
    i have read the following article which states that
    OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
    The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
    It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
    If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
    i have also run the following command
    java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
    but no success.
    How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
    All reply will be highly appreciated.
    Thnx in advance to all.

  • How do I use my wireless Led TV as a second monitor using my home network without any cables? Both of them are connected to home network

    How do I use my wireless Led TV as a second monitor to my mac book pro using my home network without any cables? Both of them are connected to home network

    Having a gateway there is not going to be a problem. We just need to configure the Time Capsule correctly to work with the 2Wire.
    You will need one ethernet cable to connect the 2Wire to the Time Capsule and a second ethernet cable to temporarily connect your computer to the Time Capsule so that it can be configured.
    The 2Wire you have now should already be broadcasting a wireless network, so once you have the Time Capsule setup, you will actually have two wireless networks there.
    Here's how to configure the Time Capsule to work with the 2Wire:
    Connect an ethernet cable from one of the LAN <-> ports on the 2Wire to the WAN (circle icon) port on the Time Capsule.
    Connect another ethernet cable temporarily from your computer to one of the LAN <-> ports on the Time Capsule
    Open Hard Drive > Applications > Utilities > AirPort Utility
    Click Manual Setup
    Click the Base Station tab below the row of icons to assign a name for the Time Capsule, a device password (write this down) and adjust time zone settings
    Click the Wireless tab below the row of icons
    Wireless Mode....Create a wireless network
    Wireless Network Name....Your choice
    Radio Mode....Automatic
    Channel...Automatic
    Wireless Security...WPA/WPA2 Personal
    Wireless Password....Your choice (write this down)
    Check mark next to....Remember password in keychain
    Click the Internet icon
    At the bottom, change the setting for Connection Sharing to "Off (Bridge Mode)"
    Click Update at the lower right and the Time Capsule will restart after 20-25 seconds and you should get the green light.
    You should now be able to connect to your Time Capsule wireless network.
    I'm not clear on whether you have tried to setup the Time Capsule to backup your computer. Post back if you need some info on that. We may need to start another thread for that as that will be a different subject.

  • How to assign a tooltip for a field in ALV editable grid?

    I have to display some instructions ( 50 chars long) for an editable field in alv.
    How to do this?
    BCALV_DEMO_TOOLTIP tells about assiging tooltip to an icon or symbol.
    Thanks,
    Ven..

    Neither of these two example programs help much in regards to tooltips against any field of any row. Both of these examples use tooltips for Icons. I have also been looking for a single example of tooltips usage outside of these two programs, and have found nothing in SAP, or on the internet, so far.
    Having said that, I have tried to implement the same method used by the later example, but have not got this to work. What I think we need is an example of this functionality where these Icons are not used!. I believe.

  • How can I use the "Copy and paste" tool in order get stamps in the same position in different pages (Acrobat XI for PC)?

    Now I am using Acrobat XI and it seems like it is not possible anymore: I am copying a stamp and I am trying to past it in anoter page, but it appears in the center of the page (or wherever it wants to...).

  • How can I use XMLBeans in a Web Services client?

    How can I use XMLBeans in a standalone Java client with a Web Service?
    I posted the message below earlier in the year, but have not yet been successful
    in my
    attempts.
    regards
    Eddie
    Hi,
    I'm trying to using XMLBeans to send a document to a web service from a standalone
    Java client. I'm using the PurchaseOrder (easypo) example document, and the service
    expects a parameter of type PurchaseOrderDocument. The client proxy class generated
    by WebLogic Workshop, however, expects to send a parameter of type PurchaseOrder.
    In the client, I can instantiate a PurchaseOrderDocument, and then obtain a PurchaseOrder
    (e.g. pod.getPurchaseOrder() ), but the returned class is not compatible with
    the PurchaseOrder type that the client proxy expects.
    In a previous attempt (not using Workshop), the client would not compile because
    it expected to send a non-abstract class with a public default constructor (presumably
    a JAX-RPC requirement), and XMLBeans had generated an interface.
    Any help would be greatly appreciated!
    thanks & regards
    Eddie

    I have been experiencing similar problems with the HTML Editor and have managed to find an answer that should start to answer some of my questions. The Apex HTML Editor Standard is actually an HTML editor called FCKeditor. The FCKeditor has a Javascript API that can be found at http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/JavaScript_API. Unfortuately this doesn't seem to give the whole answer and I found more at http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:49607.
    I needed to get the text entered within my html editor standard (e.g. P1_MYTEXT) and use it within my javascript function. I did this by using the following script
    <script language="JavaScript" type="text/javascript">
    function showtext(){
    var oEditor = FCKeditorAPI.GetInstance('P1_MYTEXT');
    var editortext = escape(oEditor.GetXHTML(oEditor.FormatOutput));
    alert(editortext);
    </script>
    Hope this helps.

  • How can I use my iPod as source for reinstalled iTunes?

    Hello @ all.
    Unfortunately I had to completely reinstall my system (WinXP Pro PC) and lost my media library!
    How can I use my iPod as a source to copy all my songs and settings (incl. covers, aso) to iTunes?
    iPod: 30GBs Video iPod
    iTunes Version: 7.0.2.16
    can u guys help me with that?
    Thanks very much!

    The transfer of purchased content to authorised computers has been introduced with iTunes 7. A paragraph on it has been added to this article: Transfer iTunes Store purchases using iPod
    The transfer of non iTMS content is designed by default to be one way from iTunes to iPod. However there is a manual method of accessing the iPod's hard drive and copying songs back to iTunes on Windows posted in this thread: MacMuse - iPod to iTunes
    If you prefer something more automated then there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod, this is just a selection. Have a look at the web pages and documentation for these, they are generally quite straightforward. You can read reviews of some of them here: Wired News - Rescue Your Stranded Tunes
    YamiPod Mac and Windows Versions
    iGadget Windows Only
    iPodCopy Mac and Windows Versions
    iPod Access Mac and Windows Versions
    PodUtil Mac and Windows Versions
    iPodCopy Mac and Windows Versions
    PodPlayer Windows Only
    CopyPod Windows Only
    If your iPod is set to update automatically take care when connecting back to your computer and an empty iTunes. You will get a message that your iPod is linked to a different library and asking if you want to link to this one and replace all your songs etc, press "Cancel". Pressing "Erase and Sync" will irretrievably remove all songs from your iPod. Your iPod should appear in the iTunes source list from where you can change the update setting to manual and use your iPod without the risk of accidentally erasing it. Check the "manually manage music and videos" box in Summary then press the Apply button. Don't uncheck Sync Music it will be unchecked by default when you choose the manual setting: Managing content manually on iPod
    Whichever of these retrieval methods you choose, keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync again. I would also advise that you get yourself an external hard drive and back your stuff up in case you have problems again. External drives are comparatively inexpensive these days and you can get loads of storage for a reasonable outlay.
