Multithreading in a Swing Application

Hello,
my Problem is:
I did a Swing Application which shows data records from a Database.
In a layer I fetch the data records from the database and create "SelectRowObjects" which are put into a Vector These SelectRowObjects have a Method "createView()" which returns a JPanel
In My Application I click on the button "fetch data" and then the EventDispatchingThread executes the DataBaseConnection ....... until The Panels are shown in my Application.
That takes a several time.
Can I create an extra Thread??
How can I do so??
Can you give me a short hint???
Thank you

Have a look here, particularly post #4 from camickr, and follow his link

  • How to give Common Background color for all JPanels in My Swing application

    Hi All,
    I am developing a swing application using The Swing Application Framework(SAF)(JSR 296). I this application i have multiple JPanel's embedded in a JTabbedPane. In this way i have three JTabbedPane embedded in a JFrame.
    Now is there any way to set a common background color for the all the JPanel's available in the application??
    I have tried using UIManager.put("Panel.background",new Color.PINK);. But it did not work.
    Also let me know if SAF has some inbuilt method or way to do this.
    Your inputs are valuable.
    Thanks in Advance,

    It is not the fault of NetBeans' GUI builder, JPanels are opaque by default, I mean whether you use Netbeans or not.Thank you!
    I stand corrected (which is short for +"I jumped red-eyed on my feet and rushed to create an SSCCE to demonstrate that JPanels are... mmm... oh well, they are opaque by default... ;-[]"+)
    NetBeans's definitely innocent then, and indeed using it would be an advantage (ctrl-click all JPanels in a form and edit the common opaque property to false) over manually coding
    To handle this it would be better idea to make a subclass of JPanel and override isOpaque() to return false. Then use this 'Trasparent Panel' for all the panels where ever transparency is required.I beg to differ. From a design standpoint, I'd find it terrible (in the pejorative sense of the word) to design a subclass to inconsistently override a getter whereas the standard API already exposes the property (both get and set) for what it's meant: specify whether the panel is opaque.
    Leveraging this subclass would mean changing all lines where a would-be-transparent JPanel is currently instantiated, and instantiate the subclass instead.
    If you're editing all such lines anyway, you might as well change the explicit new JPanel() for a call to a factory method createTransparentJPanel(); this latter could, at the programmer's discretion, implement transparency whichever way makes the programmer's life easier (subclass if he pleases, although that makes me shudder, or simply call thePanel.setOpaque(false) before returning the panel). That way the "transparency" code is centralized in a single easy to maintain location.
    I had to read the code for that latter's UI classes to find out the keys to use (+Panel.background+, Label.foreground, etc.), as I happened to not find this info in an authoritative document - I see that you seem to know thoses keys, may I ask you where you got them from?
    One of best utilities I got from this forum, written by camickr makes getting these keys and their values very easy. You can get it from his blog [(->link)|http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/]
    Definitely. I bit a pair of knucles off when discovered it monthes after cumbersomely traversing the BasicL&F code...
    Still, it is a matter-of-fact approach (and this time I don't mean that to sound pejorative), that works if you can test the result for a given JDK version and L&F, but doesn't guarantee that these keys are there to stand - an observation, but not a specification.
    Thanks TBM for highlighting this blog entry, that's the best keys list device I have found so far, but the questions still holds as to what specifies the keys.

    Hi
    In my mouse, i am having mousewheel to support scrolling.With the help of the wheel, i can scroll the pages in IE browser or any other appliction.
    In swing application ,i have scroll bar inside a JFrame.I want to have mousewheel action in my swing application to support scrolling.
    any idea ???

    As far as I know,there is no facility for detecting mouse scrolling wheel in JDK 1.3.

    First off, note that this question should have been posted in the Swing section.
    GUI events run in a separate thread (the AWT / Event Dispatch Thread) than your program.
    You should be invoking AWT/Swing events via SwingUtilities.invokeLater().
    If for whatever reason you want to have the program thread wait for the event to process
    you can use invokeAndWait().

  • Problem with "find" mode in adf/swing application

    Hi all,
    I'm working on ADF Swing application which uses MS SQL Server 2005 (JDeveloper 10g 10.1.3)
    I think that my issue might be well-known…sorry if it has been already discussed somewhere else…
    I have a problem with the “find” mode for a detail panel in a master-detail form…(To make it clear the “find” mode is switched on when clicking on the special button on a navigation panel).
    So this mode works well in a master panel, but it demonstrates strange behavior on a detail panel, i.e. it takes me two attempts to find the necessary child object and it doesn’t switch back in a simple way from this mode to the normal mode….say if we are in the department 10 (Dept is a master form) we can’t simply find KING employee (Emp is a detail form)…is there any workaround for this?
    Thanks in advance. Alex.

  • Problem in Opening HTML Page in Internet Explorer from my Swing Application

    Hi,
    I am opening a HTML file in Internet Explorer from my swing application.I am using the code given below
    private final static String WIN_FLAG = "url.dll,FileProtocolHandler";
    private final static String WIN_PATH = "rundll32";
    String cmd = WIN_PATH + " " + WIN_FLAG + " " + url;
    // url is HTML file Path
    Process p = Runtime.getRuntime().exec( cmd );
    Here there are two things i need to address ...
    1)The HTML file is opening up,but it always opens behind the swing application,that makes me every time to maximize the HTML file after it being opened up.I want to open it in front of the Swing Application.I need to implement "Always On Top" functionality for the html page.
    2)Whenever i trigger action to open different HTML page,it opens in new Internet Explorer window.
    I need to open it in same IE window.
    how to solve out these problems ??? any help would be greatly appreciated .Thanks in advance.

  • Certificate support in Java Swing application

    Hi There,
    I am new to this Certificate thing and running into issues! Would appreciate for all the help and please ignore for any stupid questions.
    Here is my scenario.
    1. I do have a client server application and client is a java swing application which connects to a Server application (Using Jetty 4.2.22 as embedded server)
    2. Initially, it had a self signed certificate but goal is to support third party certificate (i.e import in the server and then show warning to the client during login)
    If somebody has already done this or point me to some example (using Jetty APIs) that would be great help. If not, here is what I am trying to do and some questions.
    1. I tried to get some free SSL certificate from the web and imported into the server's KeyStore.
    If I do a list from the server using Keystore, this is what it looks like
    keytool -list -keystore /tmp/keystore -storepass genview
    Keystore type: JKS
    Keystore provider: SUN
    Your keystore contains 2 entries
    self, Dec 3, 2008, PrivateKeyEntry,
    Certificate fingerprint (MD5): 0D:58:E8:77:89:09:F8:2B:37:64:37:D5:03:AD:C9:0B
    rapid, Jan 6, 2009, trustedCertEntry,
    Certificate fingerprint (MD5): 64:9C:EF:2E:44:FC:C6:8F:52:07:D0:51:73:8F:CB:3
    QUESTION 1 : why the third party certificate's entry as "trustedCertEntry"? Is it always like this? Do I need to have only one certificate at a time? (If so, just remove the self signed and have 3rd party one)
    My Jetty server comes up but when I connect from Client Swing App, the "getServerCertificates()" method only returns one entry i.e self signed one but not the third party one.
    I am using like this
    URL url = new URL("https://127.0.0.1:port");
    HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
    conn.connect();
    Certificate[] certs = conn.getServerCertificates();
    Is not this API supposed to return all the server's certificate?
    Please guide me or instruct me what to do.
    Thanks,
