Where is the 'hiden' code?

Hello!
I need to controll all events in JComboBox class. I've been looking into src code of Java 1.4 to find where is the code which makes popup window of JComboBox dissapear when you click over another GUI component (not over the same JComboBox) but I was not able to find it. Does anyone know where it is?

i don't know about making it "disappear", for that I think you'd have to redo your gui itself and take out the component.
however, there is the function java.awt.Component.setEnable(false) which will disable the box.
hope that helps!

    Hi,
    If you are aware of BSP_WD_CMPWB transaction then you may be able to notice the  'View Layout' section towards the bottom of the 'View Structure' tab. In the section if you double click on the htm page it will take you to the htm page layout. The htm page has the same name as the view.

  • Where does the source code of linux reside in arch

    Just wonder where is the source code. In freebsd, all the source code is in /usr/src, does arch have that directory? or do I need to install something to get source code?

    tomk wrote:Arch does not install the source code for anything. Under /usr/src/linux-2.6.17-ARCH, you will find the kernel headers required for building other apps, but apart from that, if you want the source code for the kernel or any of the apps, you need to get it from the relevant website/ftp server/etc e.g. kernel.org for kernel source.
    no, those headers in there are for kernel modules only. the headers for applications are a sanitised copy based on 2.6.12 and exist in /usr/include/linux.
    As for the source to Arch packages, we have something similar to fbsd's ports system (ports is on fbsd isnt it or am I wrong), it's called abs:

  • THIS IS DRIVING ME CRAZY - WHERE IS THE PRINTER CODE

    I cant find the printer code????
    I cant set up eprint  ((
    Help - where is the printer code!!!!

    Which printer do you have? Were you able to enable web services on your printer? The reason I asked is because once Web Services is activated, ePrint for your printer also gets activated. When ePrint gets activated it will assign an email address to your printer. The printer code is actually the email address minus "@hpeprint.com".
    Let me know if it works.

  • Where all the ok codes will be saved

    hi
         in which table all the okcodes will be saved.
      and what is the text table where we can find the long text data for va01 and other transaction. in which table all this test table will get stored.
    regards
    sri

    Hi,
    sy-ucomm is for doing the functions what the user wishes to do at that particular event. You use it in menus and pfstatus.
    ok_code is generally used in screen as of I have used. You will define the function in the screen and you can use it in the main program.
    ok_code acts just as a temporary variable that stores the value of sy-ucomm.
    When user interacts with the screen elements, the function code that you have assigned is filled in the sy-ucomm field which is turn gets reflected in OK_CODE.
    In your ABAP programs, you should work with the OK_CODE field instead of SY-UCOMM. There are two reasons for this: Firstly, the ABAP program has full control over fields declared within it, and secondly, you should never change the value of an ABAP system field. However, you should also always initialize the OK_CODE field in an ABAP program for the following reason:
    In the same way that the OK_CODE field in the ABAP program and the system field SY-UCOMM receive the contents of the corresponding screen fields in the PAI event, their contents are also assigned to the OK_CODE screen field and system field SYST-UCOMM in the PBO event. Therefore, you must clear the OK_CODE field in the ABAP program to ensure that the function code of a screen is not already filled in the PBO event with an unwanted value. This is particularly important when the next PAI event can be triggered with an empty function code (for example, using ENTER). Empty function codes do not affect SY-UCOMM or the OK_CODE field, and consequently, the old field contents are transported.
    I hope it gives you the difference between the two.
    Reward if usefull..

  • Where is the HTML-Code for the Dashboard-Links defined? How to edit it?

    Hello everyone,
    I'd like to know where HTML-Code for the Dashboard-Links (My Dashboard, insert random Dashboardname here, ...) is defined.
    Inspecting HTML-Code via the browser, i'll got the following HTML-Tag:
    an <a'' href="...url"... class="CurrentPortal" name="DashboardBannerLink" title="...">Dashboard-name</a''>
    What i know is, that i can modify portalbanner.css and edit the style of those links.
    But thats not what i want, though. I want to modify the html-code itself, for example change the layout of the table etc, to meet our company's corporate design requirements.
    Thats why i tried to find the terms PortalLink and CurrentPortal within the Message-Database (/msgdb).
    Unfortunately, i got no results.
    As a consequence, I believe HTML for those Links is generated by saw.dll internally and therefore can not be edited.
    Now i need someone to prove me wrong ;)
    Thanks in advance,
    Chris

    -had to edit the html tag, as the code was turned into a clickable link when i posted the thread

    I still didn't find a solution until now, although i checked almost every xml file, that i was able to find.
    At the moment I am sure, that it would be necessary to edit sawm-Parameter "bannerHtml" to meet my requirements. Now, i dont know whether its possible to edit it or not, since those saw-parameters do not seem to be documented on the web.
    That's the part, i found in dashboardtemplates.xml (Line: 362)
    <WebMessage name="kuiDashboardBanner" translate="no"><!-- Param bannerHtml --><!-- Param dashboardsURL -->
    <HTML>
    <table class="PortalBanner" width="100%" border="0" cellspacing="0">

  • Where in the JTextArea code is line/word wrapping handled?

    Hi all--
    I was making a custom renderer using a JTextArea, and was looking in the source code for JTextArea trying to figure out how it determines when to break a line given it's width and the current font...but I can't find it anywhere. I can find this function:
    public void setLineWrap(boolean wrap) {
            boolean old = this.wrap;
            this.wrap = wrap;
            firePropertyChange("lineWrap", old, wrap);
        }but it appears to simply set a private boolean called "wrap" that isn't in its superclass JTextComponent. So one can only imagine that it must somehow calculate where to wrap its text. But this code is no where to be found in JTextArea. In fact, the only thing I can find is that it fires this "lineWrap" property change, but I cannot find in either JTextArea or JTextComponent where this event is handled to recalculate where to draw the string and when to wrap it to a new line.
    Mostly I'm just curious how it's done more than anything else. Anyone know where the missing code is to handle this?

    Yeah, this stuff gets pretty twisted. The main entry point is the getViewFactory() method in the RootView member class of BasicTextUI. (RootView is just what it sounds like: the root of whatever View hierarchy finally gets built.) It first tries to get a ViewFactory from the EditorKit, and if that doesn't work, it returns the enclosing BasicTextUI object. If the component being constructed is a JTextPane or JEditorPane, the EditorKit will be a StyledEditorKit or a subclass thereof, which will provide a ViewFactory that can vary with the kind of document being displayed/edited. But in the case of JTextArea, it will be a DefaultEditorKit, which returns null from its getViewFactory() method, meaning the BasicTextUI object is expected to serve as the ViewFactory. BasicTextUI provides only a dummy implementation of the ViewFactory interface, but its subclass, BasicTextAreaUI, implements create(Element) to return either a PlainView or a WrappedPlainView, depending on the relevant setting the the JTextArea.

  • Where Is The Edge Code Compiler?

    I was just wondering where the Java Compiler is supposed to be accessed in the Edge Code application? I have a fairly long Java source code program which pretty badly needs compilation as soon as possible.

    There is no Java compiler component for Edge Code. Edge Code is designed for JavaScript (not Java) developers.

    You can copy it from some VI made in previous version of LV. It works fine.

  • Where's the source code for the JavaFX 8 Samples?

    Hi,
    I just downloaded the samples for JavaFX 8 and the menu popup on the top left really caught my attention.
    I'd like to study the source code for it. Does anyone know where I can find it?
    I expected it here http://hg.openjdk.java.net/openjfx/8/master/rt/file but it seems it's not there.
    Alternatively: Jasper Potts presented a Kiosk App at Devoxx 2012 (Antwerp), which was also used at JavaOne. I think this app uses the same Menu. And he said sources are available. But I can't remember the link.

    Oh, too obvious. They are directly included into the zip. My bad I didn't notice them. I had expected them to be online somewhere. Thanks!
