How do you perceive a swing through the console Panel?

While I'm not a Swing / GUI developer, I have a question. How do you perceive a simple swing through the console panel?

I created a simple method of hand [see below]. It compiles perfectly, but when I go to run the compiled file, nothing happens. He returned to the command line. I have a feeling I'm missing something, but I don't know exactly what it is. Can someone point me in the right direction?

Thank you!

     public static void main (String args[]) {
          JPanel header = new JPanel();
          
          JPanel spacer = new JPanel();
          spacer.setPreferredSize(new Dimension(150, 20));
          spacer.setPreferredSize(new Dimension (150, 20));     
                    
          header.add(spacer);
          
          JLabel title = new JLabel("Current Testing");
          header.add(title);
          
          JPanel spacer2 = new JPanel();
          spacer2.setPreferredSize(new Dimension(150, 20));
          spacer2.setPreferredSize(new Dimension (150, 20));
          
          header.add(spacer2);
          
          JSeparator jSep = new JSeparator();
          header.add(jSep);
     }

You must add the Group of experts to a top-level container and display this container.

Start by reading the Swing tutorial [url http://download.oracle.com/javase/tutorial/uiswing/TOC.html]. Maybe start with the section "use of the Swing components. Choose a component that you want to use, and look at this article for examples of work.

    I bought a new diagnosis program and quarantined the virus once it has been identified. I tried to remove the virus in several ways, but it comes back. The best way that I thought would work enter safe mode and by changing the attributes of the svchost.exe file and then delete and checked the registry AWI hwo to the Web site, but it continues to be problematic.

    Hello

    During the uninstallation of antivirus/antispyware/security programs always check for an uninstall
    tool and/or removal instructions special to avoid leftovers.

    ------------------------------

    Here's what I use and recommend: (these are all free and very effective versions.)

    Avast and Prevx proved extremely reliable and compatible with all I have
    launched on them. Microsoft Security Essentials and Prevx have also proven to be very
    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leave the file system, Web,.
    Operational network (Script and behavior are also recommended in Ver 6 +).

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (It may temporarily turn off with the little icon to the left of the + bottom
    right of IE)

    Two versions of Avast are available 6.x and 4.8 x

    Avast - home - free - 6.x stop shields you do not use (except files, Web, network, &)
    Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
    Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
    Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
    disabled - click OK
    http://www.avast.com/free-antivirus-download

    Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
    and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
    Finish those you don't use).
    http://www.avast.com/free-antivirus-download#TAB4

    Or use Microsoft Security Essentials - free
    http://www.Microsoft.com/Security_Essentials/

    Prevx works well alongside MSE or Avast

    Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
    programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
    or use Google to see how to remove.
    http://www.prevx.com/   <-->
    http://info.prevx.com/downloadcsi.asp?prevx=Y<-->

    Choice of PCmag editor - Prevx-
    http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
    would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
    (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
    never find anything of note that I started to use this configuration.

  • How would you like non-destructive change the color of some pixels depends only on their RGB value?

    How would you like non-destructive change the color of some pixels depends only on their current color?

    Constraints: the goal is to avoid having to select with the lasso tool or any other tool. I'm talking about adjustment layers here, who would not need to select parts of the first image.

    The input image has only a haldful of discrete colors: it is made of, say, about 10 areas with 10 different colors, alias 10 different RGB values.

    The goal is to find a way to organize the adjustment layers and only pixels with given RGB value (for example) blue, while some other pixels with another RGB value data become red, etc. ?

    I will then apply these to each image adjustment layers in an animation, to selectively change the colors.

    If I understand you correctly, "Mix" so should work.

    Here, you can target specific values/ranges in each channel, for the underlying layer and current standards.

  • GANYMEDE user through the console?

    Hi all

    We had a strange problem with authentication via GANYMEDE. Logging on to a switch via VTY works well... I enter my user name and PW and start at the privileged exec prompt. But when I am trying to connect through the console, I won't get it priviledge rights exec without entering in a passage of the ena. This phenomenon occurs in different versions of IOS.

    Config looks like this:

    AAA new-model

    AAA authentication login default group Ganymede + local

    the AAA authentication enable default group Ganymede + activate

    default AAA authorization exec group Ganymede + none

    AAA authorization network default group Ganymede + local

    AAA accounting send stop-record an authentication failure

    AAA accounting newinfo periodic update 15

    AAA accounting exec default start-stop Ganymede group.

    orders accounting AAA 15 by default start-stop Ganymede group.

    Default connection accounting AAA power Ganymede group.

    !

    username privilege 15 password

    What you are experiencing is a behavior of Cisco implements voluntarily. As has been explained to me, to directly enter mode privilege is a combination of authentication and authorization. For the vty ports it is enabled. For the console, it is the authentication, but not the component of the authorisation. The reason for this is that it is easy to misconfigure the framework for approval of the configuration. It's one thing to lock you into the vty ports and it's something of another (and more serious) If you lock you out of the console. So as a safety mechanism Cisco only default not apply permission on the console. You will need to enter the password to enable on the console.

  • How can I remove a link in the links Panel?

    I moved an item out of the folder of links on a project that I train in IDCC and opening of the project he said, rightly, that a link is missing. When I go in the links Panel, I see the alert that the bound element is missing, that I know, and I want to remove the link in the links Panel, but do not see any option to do this, also the delete key does nothing when the item is highlighted and do a right-click (^ click) don't offer no delete choice either. How can I remove this item in the links Panel?

  • How can I make javascript - entry via the console action/target - easier to navigate?

    Hi all

    Someone find that navigate the continuous and uninterrupted lines constituting the blocks/paragraphs of the text in the JavaScript code, entered through the console of the target/action, is of a daunting task, especially when making some amends?

    Other than the obliques, which seem to cause problems when published and displayed through some browsers - does anyone have a cross-platform solution for separating the code in lines sensible and readable for ease of navigation?

    Thanks much for any help.
