Focus Travel in the JInternalFrames (ctrl+tab and ctrl+shift+tab)

hi ,
i have a JFrame inside which i have a JInternalFrame.
in this JInternalframe I have 4 JPanels when I click ctrl-tab from a JFrame the focus should go to
next panel'sand similar for other panels vice-verse ctrl-shift-tab .
how to achieve this .
looking for help.
Thanks in Advance

According to my [Key Bindings|http://www.camick.com/java/blog.html?name=key-bindings] program those keys are already mapped to the next/previous frame Action.
However, the problem seems to be that the KeyboardFocusManager is intercepting the KeyStroke so you need to remove those KeyStrokes from the focus traversal set. I don't know how to do that, but you can create a new set:
Set set = new HashSet();
set.add( KeyStroke.getKeyStroke( "TAB" ) );
frame.setFocusTraversalKeys( KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set );You will need to use similiar code for the backward traversal keys.

  • I am traveling from the US to France and have a Macbook Pro. Can I just use a plug adaptor or do I need a power converter to plug in?

    I am traveling from the US to France and have a Macbook Pro. Can I just use a plug adaptor or do I need a power converter to plug in?

    Just an adapter to change the US plug style to the one in the country you are going to. The AC charger will do the rest. It is rated for 120-240 volts and will adjust on  its own.

  • I am travelling to the Philippines next week and I have been told my iphone and ipad chargers will work with the 220v there.  Do I need to be concerned and buy any type of converter?

    I am traveling to the Philippines next week and am confused on whether I need to buy a converter to be able to charge my Iphone (and Ipad).  I was told I did not as the chargers were universal and automatically converted anywhere from 100 to 240v depending on what you plug into. 
    I would just like some more confirmations if any one has traveled internationally.
    Thank you.

    No, but most international airports I have been to have convenience stores that sell the plug adapters.  And there are always other shops with the adapters so it is easy to get exactly what you need after you get there.

  • What is the Mac equivalent of the command "ctrl shift  I"  for a PC

    HI
    what is the Mac equivalent of the command "ctrl+shift + I"  for a PC to get to the cookies and delete them

    It varies depending on which browser you're using. In Safari, choose Preferences from the Safari menu, click on the Privacy tab, and then on Details.

  • The new field blur and tilt shift filters have stopped working

    The new field blur and and tilt shift filters worked a few times but are now greyed out in the menus. Any ideas why? Thanks.

    Did you check the settings Chris mentioned? Your issue sounds like there might be a video card or driver issue, which can disable the GPU related features and give you a lesser version of the blur filters. See this link for some troubleshooting suggestions. See if issues with the video card have disabled - Edit>preferences>performance use graphics processor.  Also check the advanced settings drawing modes. Be sure you have the current driver (system is updated and current on mac or go to the video manufacturer's website for pc) . That is often the cure.
    You might want to copy your system information (photoshop help>system info)  here for us to look at.

  • "When you create a new tab, the Location bar will be focused so you can just start typing the name or address of the website you want to go to" Um...no it doesn't. IN the "improved" Firefox 5, the focus remains on the previously opened tab...very annoying

    New tabs are not getting focus. Typing an address after opening a tab opens the address in the first tab, not in the tab that was just opened

    Tools > Options > Tabs: [ ] "When I open a link in a new tab, switch to it immediately"
    This issue can be caused by an add-on that isn't working properly.
    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    * Don't make any changes on the Safe mode start window.

  • I am travelling from the US to France and England - do I need a voltage converter or can I just plug my iphone 4 and ipad into a plug converter?

    Both France and UK use 240 v and I have a US iPad and iPhone4.  Can I just just the plug converter or do I need to use a voltage converter for both?
    Thanks!

    No voltage conversion needed, just an adaptor for the plug, anywhere you go.

  • Focus Lost when Dragging JInternalFrame?

    Hopefully this should be a simple question:
    I have a JInternalFrame with numerous simple components like JTextFields.
    When I click the title bar, or click and drag the Frame, the JTextField that had focus prior to that clicking loses focus. Focus goes to the Main Frame window, and if I use setFocusable(false) on the main frame, focus goes nowhere (getFocusOwner() == null).
    I want focus to remain in the same component (the JTextField) when clicking on the title bar and when dragging. How do I do this?
    I'm using jdk1.4.1_01. Thanks for the help!
    Joel

    I HAVE AN ANSWER!!!
    First of all, when you click on the JInternalFrame's title bar, I was losing focus. To fix this, I added a mouse listener to the title bar. I then reset my focus on a mouse clicked event. To find the title bar, I did the following:
    private BasicInternalFrameTitlePane findTitleBar()
        Component[] comps = this.getComponents();
        for (int i = 0; i < comps.length; i++)
             if (comps[i] instanceof BasicInternalFrameTitlePane)
                  return (BasicInternalFrameTitlePane)comps;
    return null;
    If the findTitleBar method doesn't return a null, add a mouse listener to it. In the mouseClicked method, reset your focus. I found by using the SwingUtilities.invokeLater, it worked better. So my mouseClicked method looked like:
    public void mouseClicked(MouseEvent  e)
       initFocusFor(getFocusComponent());
    public void initFocusFor(final JComponent comp )
       if (comp == null)
          return;
       SwingUtilities.invokeLater(new Runnable()
         public void run()
            comp.setRequestFocusEnabled( true );
            comp.requestFocusInWindow();
    }Now, for the resizing and dragging.... I was losing my focus on that as well. I believe my desktop manager was getting the focus on resizing and dragging. So, on my subclassed desktop manager, I just added logic to reset my focus on the JInternalFrame on the following methods: endDraggingFrame and endResizingFrame.
    Hope this helps someone else.     

  • Since the last update, I cannot attach a file to my email in MobileMe. It has always worked until the latest update. Now, nothing happens when you click on the paper clip icon and 'choose' the file to add.

    I am using MobileMe on my Mac. Until the last update a few days ago, Firefox always allowed me to attach files to my emails. Now, when I click on the paper clip, and it takes to me find the file I want to attach, and I highlight the file I want to attach and click on 'open', nothing at all happens. the screen just goes back to my email. It always worked before, it does not now. It DOES work on Safari but I hate Safari, i want to use firefox.

  • Ctrl+shift+U - Unicode input, how to disable?

    Anyone knows how to disable ctrl+shift+u unicode input?
    Whenever I press ctrl+shift+u, I get an underlined "u" and can enter some unicode number. However, I don't need it, and because of this, for example in qt creator the predefined "ctrl+shift+u" keyboard shortcut doesn't work.
    I have no idea where this mapping comes from (obviously not qt, since ctrl+shift+u is mapped to an important shortcut), but maybe gnome or the xserver?
    Thanks already

    I just updated from Ubuntu 13.10 to Ubuntu 14.04 and I found that I have exactly this same problem, which is being caused by ibus (my up to date Arch system doesn't seem to have the problem).  You can see if ibus is running on your system via:
    $ ps aux | grep -i ibus

    I'm running XFCE and there is now a "Language Support" icon in the "Settings" panel (select "Settings Manager" on the main menu.)  The Language Support app contains a "Keyboard input method system" selection on Language tab.  I changed it from 'IBus' to 'None' and now Ctrl+Shift+u works again.  (This is a quick and dirty solution that works for me because I'm only using English and never have to type special characters.)

  • [LAVA Cross Post] CTRL+SHIFT+Alpha Shortcuts don't work in LabVIEW

    Cross-post from LAVA: http://lavag.org/topic/15619-ctrlshift-shortcuts-sometimes-not-working-in-labview/
    Bug Synopsis: CTRL+SHIFT+Alpha shortcuts do not work in LabVIEW. Most notably, CTRL+SHIFT+Z, CTRL+SHIFT+E, and CTRL+SHIFT+S
    Test setup: LV2012 32bit with f1 patch running in Win7 64bit inside a Parallels 8 VM in OS X 10.8.1
    To summarize the testing I have tried:
    Many different LabVIEW, Guest OS, and Host OS combinations all fail, including:
    LV2012f1 32 and 64 bit, and LV2009 32 bit
    Win7 32 and 64bit, and also WinXP x64
    Parallels 7 and Parallels 8
    OS X 10.7 and 10.8
    Capturing the keyboard by the VM
    Twiddling every keyboard setting possible on Parallels, Guest, and Host
    Reinstalling keyboard drivers
    Plugging in a known-good keyboard that works on a native Windows machine
    Deleting LabVIEW.ini and letting it regenerate
    Remapping the shortcuts from, e.g., CTRL+SHIFT+E to CTRL+E - in this case, "Show in Project" works, so this might indicate it's a problem registering the shortcut press, not invoking the action itself.
    Sending the keystrokes via on-screen keyboards from both Guest and Host
    Sending the keystrokes via SendInput from user32.dll WinAPI
    Testing every imaginable combo of FN, CONTROL, ALT/OPTION, COMMAND/CMD, SHIFT
    Reinstalling VMs from scratch and reinstalling LV
    Here's a kicker: CTRL+SHIFT+Alpha shortcuts work fine on other Windows programs (I've tried 4 different programs, including Chrome, Notepad++, Paint.NET), yet it does NOT work for VIPM with CTRL+SHIFT+C. This means that the only two programs where the CTRL+SHIFT+Alpha bugs exist are both LabVIEW-related.
    Here's another kicker: It's only CTRL+SHIFT+Alpha shortcuts with the prob - CTRL+SHIFT+3 properly toggles grid alignment, and the "Tools >> Options >> Menu shortcuts" will register any CTRL+SHIFT+Non-alpha shortcut; it just does not respond to the CTRL+SHIFT+Alpha shortcuts.
    Any new troubleshooting ideas are highly appreciated; please feel free to jump in here or on LAVA.

  • How to stop ctrl+shift+s in reader

    I am opening a pdf in browser as popup. I have hidden the browser menu bar and reader plug-in's copy/save bar. So user is not able to select save command from any menu. But he can use the shortcuts (ctrl+shift+s) to save the pdf. I think this is reader's plug in command can I restrict this.
    My intention is not to make user, able to save the pdf to his system directly. Cache is not a problem.
    Please help me....

    I m agreed what u said.
    As I said before cache is not problem.
    I just do not want to give any option to the user through the popup window(which contains the pdf) to save the pdf.

  • How do I clear the chash instantly with refresh key (+ Shift, Control or Alt)

    Hello,
    I, build websites online using "Firefox" latest version, I modify the website I work on and refresh the browser, sometimes the browser will not refresh.

    You can reload the page and bypass the cache with:
    * Press and hold Shift and left-click the Reload button.
    * Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
    * Press "Cmd + Shift + R" (MAC)
    See [[Keyboard shortcuts]] and [[Mouse shortcuts]]
