Stopping tab from moving to the next focus component

I have a single TextInput field in my component and I want to
stop the tab key from advancing the focus when I have an error in
the field. I have tried using setFocus() and that seems to do it
although I lose the caret in the text input field. Also when I tab
I notice that even though I am telling the component that the next
focus is the TextInput field it still goes to the Internet Explorer
address bar. Any ideas?

Append the system's line separator usingjava.lang.System.getProperty( "line.separator" );Then the added line will be placed as you've wanted. Code will be written like below:yourTextArea.append( System.getProperty( "line.separator" ) );
yourTextArea.append( yourStringToAppend );Hope it helps.

  • Is there a setting that prevents you from moving into the next "set?"

    A couple times I have mistakenly hit my "next patch" button one too many and ended up in the next set. This is a problem because the backing track that was playing suddenly stops because I am in the next set, understandably.
    Is there a setting or mapping that I can use so I can't enter the next set using the "next patch" button and only use the "next set" button.
    Any ideas out there???
    Thanks!!!!

    Forget the physical controller button for a moment, that's a red herring.
    I have a single button on the screen that for SOME PATCHES ONLY, has the action "Current Program Number" associated with it. In the "Map Parameter" area, there are two sliders for which you set values for "Button On" and Button Off". Those get set to the same value, which is the value of the patch to which you want to go next.
    So suppose you have patch 1 and in that batch, the aforementioned button has its values set to 5, then if you press that button WHEN YOU ARE IN PATCH 1, then you will switch to patch 5. Now, further suppose that in patch 5, that same button has its values set for patch 12. Then pressing that button WHEN YOU ARE IN PATCH 5, will take you to patch 12.
    Now, if you go into learn mode and associate that screen button with a physical controller button, then you can do exactly the same thing by pressing that physical button. The patch to which you will go will depend on which patch is currently active. If the last patch in that chain doesn't have any values associated with the button, then pressing that button (via your controller) will do nothing at all.
    I suppose that if you're concerned with hitting that controller button by mistake, then you might actually want to have two buttons, one that takes you to the next patch in your chain, the other to the previous.

  • Stopping clips from moving along the timeline.....

    Hiya
    Doing quite well with FCE. One thing I haven't worked out is how to 'lock' things in the timeline. eg: if I delete something or change the length then everything else shifts along the timeline.
    Please help!

    There are two types of DELETE in FCE/FCP: 'ripple' and 'lift.'
    A lift delete can be performed using the {delete} key on a standard keyboard (aka as backspace delete). This is the key just below the F11 and F12 keys. A lift delete will delete the selected clip without causing the other clips on the Timeline to shift.
    A ripple delete can be performed using the {del} key (aka forward delete). This key is two keys below the F13 key (above the left arrow key) on a standard keyboard. The ripple delete will delete the selected clip and shift clips other clips on the Timeline to fill the gap.

  • How do I stop firefox from automatically placing the cursor in a textbox?

    How do I stop Firefox from automatically placing the cursor in a text box? On certain pages such as Google.com the cursor will be moved to the search text box automatically after a couple seconds from the page loading. So I'll be typing in the address bar or something and then half of what I am typing in the address bar becomes cut off and starts being entered in the Google.com text box for search. The same happens on Facebook.com and the cursor is automatically moved to the Status Update text box. I assume this is a built in "feature" of the web page, but it's damn annoying. Especially when I start typing in my status update box on Facebook before the page completely loads and then halfway through typing (once the page is done loading) my cursor is moved to the starting position of the text area and my text is cut off.
    Just the be clear the actual mouse pointer isn't being moved, just the prompt for entering text.
    How can this be stopped?
    == This happened ==
    Every time Firefox opened
    == Started since I can remember

    This problem has grown worse over the last couple of years. I use Firefox on Mac and Windows. I consider this problem to be a bug. Here's why: Event Driven interfaces, e.g., OSX and Windows, are never supposed to change typing-cursor focus WHILE SOMEONE'S TYPING!!!
    Firefox allows websites to change focus WHILE USERS TYPE!
    Hey, sorry for the caps, but I haven't used those for awhile and that's kind of fun. But really, more and more websites steal typing-cursor focus WHILE USERS TYPE.
    Efff them, but really, Eff Firefox for allowing this.
    It's almost like a symptom of our hyper scattered age where our attention jumps here and there.
    But really... I love Firefox, some of my best friends are Firefox, they're good people, don't get me wrong, but damn it, WHEN SOMEONE IS TYPING THE UNASSAILABLE RULE OF EVENT DRIVEN DESIGN IS NOTHING ELSE SHOULD CHANGE FOCUS WHILE SOMEONE IS TYPING!!!!
    FIX THIS PLEASE.
    Oh, I just ran out of capital letters. :) :) :)

  • Please make a permanent solution to stop applications from running in the background

    'multitasking' is not a very usefull invention and should have a permanent solution, to stop applications from running in the background instead of having to go in and exit them. the only thing that is usefull is to go in and click on next song under music, everything else running in the background can just be exited as far as im concerned, its not like i have 400 applications, and i have to go searching through my phone to find them

    Push twice on the Home button to display running apps. Press on one and hold until they wiggle. Tap on the circled red "x" to remove each from the background. Note that backgrounded apps are not actually running until you access them except for those that have been written to run concurrently such as Music, which can continue playing while you are using other apps.

    You should take it to an Apple store or an AASP (Authorized Apple Service Provider) Carefully inspect the hinge joint and make sure there is no debris that you can see, you can try carefully sliding some sticky tape thru the joint to clear any loose stuff out. But this sounds like there might be more going on here, and the hinge is something that you do not want to fool with.

    Hi,
    Did you find a way to solve your problem ? We have exactly the same for one application and we are using the same version of HFM : 11.1.2.1.
    This problem is only about webforms. We can correctly input data through Data Grids or Client 32.
    Thank you in advance for your answer.

  • How do I stop programs from running in the background?

    How do I stop programs from running in the background?  In the old system you could delete them.

    Most of those apps aren't running in the background, but what you are asking is how to close the apps.
    To close an app in iOS 7, drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.

  • Songs are stopping halfway and skipping to the next song

    I recently imported some new songs onto my itunes, and some songs are stopping halfway and skipping to the next song. This is happening both on my itunes on mac and on my ipod classic. I have already checked the ending time of the songs, and also checked the audio file to see if it was corrupted. I have also tried deleting the song and importing it on itunes again, but nothing changes. It's becoming quite annoying, and I would really like to fix the problem..

    I, too, am having this problem as of two updates ago. It' been like this for about two weeks now. Music stops, songs skip like I'm using an old CD player and went over a bump - just abruptly stopping/changing to the next song. I've also noticed VERY clear and sudden changes in song quality while streaming, it's a bit jarring.
    I have a Samsung Galaxy S4. I'm in the Phoenix, AZ area, and I'm using T-Mobile.
    I have tried the following:
    Restart phone 
    Clear data
    Uninstall and reinstall
    Lower streaming quality
    I've noticed this seems to only happen on streamed songs.. downloaded ones are OK. Everything was fine until the update that changed the 'Your Music' section :(
    Edit: Wifi works fine.. It seems to either be a) streaming over T-Mobile or b) how Spotify handles streaming/slow connections/whatever has changed in a recent update. Can past and future repliers include their mobile carrier to see if there's a trend?

  • When I have two audio clips next to eachother, how do i 'dissolve' them so its a smooth transition from one to the next?

    I have a few clips besides eachother.. levels are up and down, but i want to do an 'audio dissolve' per se, or fade from one audio clip into the other.. to make it smooth..  how do i do this? thanks

    One might think that you could simply drop a transition effect on to two connected audio clips to fade from one to the next. In fact, that's what the menu seems to imply:
    But you can not. No transition effects can be attached to Connected Clips. The menu lies!
    There are however several ways to do accomplish the transition.
    You can overlap them and drag the fade gadgets like this:
    Another way is to transform the audio clips to a secondary Storyline (command-g). This will allow you to use transitions.
