Keyboard listener question

Hey guys
Just wondering if there is a way to change a keyboard listener I have set up, so that instead of reacting instantly when it hears a key_UP event, it waits to see if there's another KEY_UP within, say 50ms?
Cheers
Shaun

Use Timer class:
var myTimer:Timer = new Timer(50, 1);
function keyUpHandler(event:KeyboardEvent):void
     if (myTimer.running)
          myTimer.stop();
          //     code to do what you want after second KEU_UP within 50 ms
     }else{
          myTimer.start();

Registering keyboard listener

Hi,
In my application I have a JFrame and I add panels to the frame. The JFrame has a menubar which contains menus and menuitems. My problem is that I want to catch keyboard events. After the frame comes up, I should be able to hit certain keys and perform certain actions which will modify the UI.
I tried adding a keyboard listener to the content pane of the frame but it didn't work. What I did was as follows:
getContentPane.addkeyListener( new KeyAdapter()
public void keyReleased (KeyEvent ke)
// do something
Can anybody help?
thanks a lot in advance,
-Amitabh

The events are probably being handled at a lower level (subcomponents) and never getting fired to the ContentPane.
I would suggest extending the DefaultKeyboardFocusManager class and overridding the processKeyEvent or dispatchKeyEvent method.
public class YourKeyboardFocusManager extends DefaultKeyboardFocusManager
    private   KeyboardFocusManager m_initialManager   = KeyboardFocusManager.getCurrentKeyboardFocusManager();
    public YourKeyboardFocusManager()
        super();
        KeyboardFocusManager.setCurrentKeyboardFocusManager(this);
    public boolean dispatchKeyEvent(KeyEvent event)
        Component component = event.getComponent();
        System.out.println("component dispatching the KeyEvent : "+component.getClass().getName());
        switch (event.getKeyCode())
          case KeyEvent.VK_WHATEVER_KEY_YOU_WANT:
                 //DO YOUR STUFF HERE
                  event.consume();
                  break;
          default:
                return m_initialManager.dispatchKeyEvent(event);
         return m_initialManager.dispatchKeyEvent(event);
} Now this class will pick up every single key event posted to the AWTEventQueue before it is dispatched. This may be overkill but it does what you need. You can look into setting up your own keyevent dispatcher if you want and adding that to the current KeyboardFocusManager opposed to writing your own like above.
Anyway, should be enough here to fix your problem.
Hope this helps

Jampack and keyboard connection questions

2 questions:
1. I have just bought GB Jampack (the one with lots of extra loops), but can't seem to notice any difference. How do I know that the disc has downloaded OK? Can't remember how many loops were there in the first place!
2. I'm trying to connect an Roland SK-50 Soundcanvas keyboard. Do I need some sort of interface or drivers before it will work?
Very basic questions, I know, but hey, that's what this discussion group is for isn't it?!
Regards
Mark

How do I know that the disc has downloaded OK?
If you bought the JamPack DVD you didn't download anything. Did you run the installer on the JamPack DVD?
To see just loops from your JamPack disc, open the Loop Browser and click on the top bar where it likely says "Loops" with a double arrow, and select "JamPack 1". Then only loops from the JamPack will show in the loop browser.
Re: the Keyboard
What kind of conection doesd it have? All I could find was " complete with direct Mac or PC connection" and "Connections: MIDI In, MIDI Out, MIDI Thru, Line In (LR), Line Out (LR), Computer port, and 1/8" stereo headphones jack."
"Computer Port" isn't very specific. Is it a USB connection? You might need to find a driver for it. Does the Manual say anything about installing software to make it work?

IBook G4 Keyboard Replacement Question

I need to replace the keyboard on my iBook G4 14" 1.42GHz which I bought in Sep 2005.
However, I can't figure out which replacement keyboards online are compatible.
The bar code number on the keyboard is KY5322DDTGKA.
I see sellers saying that their replacement keyboards are compatible with p/n 922-6637, 922-6189, 922-6913, PBF8415 for instance. I can't figure out though if my iBook is compatible with this.
Can someone give me the correct Apple part number for a replacement keyboard that is compatible with my iBook?
Thanks

mac-question:
Welcome to Apple Discussions.
iFixit lists Apple part numbers, then says, this keyboard works in all G4 14" iBooks.
PowerBook Medic also suggests the part is interchangeable.
PowerBookTech offers these links which you can check out.
Be sure you call or email and ask questions before you buy, to be sure you are getting the right part.

Third-party keyboard security question

Hello everyone,
Apple says that third-party keyboard developers have access to all of the data user types. Then it says "If you enable Full Access", developers are permitted to access, collect and transmit the data you type".
So my questions are:
1. Do developers have access to the data I type with full access enabled or no?
2. If I'm using apple keyboard but third-party keyboard is installed do they still have access to the data I type?
For example: When I access to my credit card I will use apple keyboard but while I'm chat in Facebook or watsApp I use third-party keyboard. Do they(Third-party keyboard devs) have access to my credit card password?

NO. The 3rd party keyboard is only communicating with your iPad.

10g listener question

Hi
All,
First question
When I do some minor modification in tnsnames.ora. Do I Need to stop and start listener again.
Second question
And If I want to stop and start listener Do I need to stop all the databases before I can stop and start listener ? (9i and 10g)
Thanks,
Vishal

When I do some minor modification in tnsnames.ora. Do I Need to stop and start listener again.No, tnsnames.ora is totally independant to the listener.
And If I want to stop and start listener Do I need to stop all the databases before I can stop and start listener ? (9i and 10g)No, the listener is used only to connect new client to the server, once the connection is done, listener is not used anymore for that connection.
Note you can reload instead of stop and start the listener.

Keyboard layout question

Out of interest, is there an easy way to make/print/download or otherwise obtain a visual keymap for the Mackbook - what keys do what with given modifiers etc?
I know you can use the keyboard viewer, I was thinking of something hardcopy for a visual reference.
On that note, can anyone tell me what fn-6 on the UK keyboard (a sort of square box with a superimposed 'x') is for?
Thanks in advance.

Hey there henripla,
I compared your keyboard to a great list i found on wikipedia, I believe it most closely resembles a Portuguese Brazilian Keyboard. Looking at it key for key, it is an exact match with the exception of the E key. Hope this helps!
Oh and also just to help, here's the part list for the T420 keyboard!

Keyboard illumination question.

I just bought a 15 in macbook pro. the question I have is that I thought the keyboard was only suppose to illuminate when there was no light. My keyboard stays lit up all the time. I even used it in a brightly lit room and it is still on. Do i need to change some settings or what? any help appreciated, thanks.

You think it should do the complete opposite of what it does, which, imo, is only logical. The illumination stays on all the time, even when it's lit, but then gets dimmer when the light goes down (if you have the key illuminations set to full and then turn the light off, you'll see it goes down halfway). I'm like you, this seems backwards, but for some reason this is the way Apple has set it up. I wrote them a message saying I thought this was stupid. You should too. Maybe they're fix it.

Terminal keyboard shortcut question

Hello. I'm asking this question on behalf of a tech who works in our school. He would like to know what the keyboard shortcut on a Mac is to take you to the end of a line or the beginning of a line. (Apparently on a pc it is the home and end keys but on the Mac that takes him back to the very start of to the very end.) Sorry if this is a silly question.
Jenny

The standard keys to move to end of line is Ctrl-E.
Ctrl-A will take you to the beginning of the line
Other useful control characters include Ctrl-T (transpose two characters) and Ctrl-U (erase line)

Multiple USB keyboard controller question

hey everyone ... Happy new year by the way !
quick question .. i want to use 2 USB controllers to play one source ( software synth )
I have a USB audio interface with a midi keyboard controller patched in the mdi input jack and would like to use another USB keyboard ( in another available USB port ) to access the same source track .
When I record enable the track with the instrument , my midi controller can the synth but the USB one won't
I checked the audio midi setup utility and coreMidi recognizes both midi inputs but Logic Pro X won't
Does this has to be set up through the environment window of Logic ? I thought that coreMidi would take care of things automatically for me .
thanks for your help !

Hi
Under normal circumstances, 2 keyboards that show up OK in Audio MIDI Setup should work fine.
In Audio MIDI Setup (MIDI Window), click the "Test Setup" button and play some notes on each keyboard. You should see a blue flash on the Interface Icons in AMS, and you should hear a beep through the System Audio when you release the keys. (Turn this off when done).
In Logic, check the MIDI transmission channels of each keyboard (some instrument plugs are channel-sensitive).

Keyboard Problems Question button

The question and forward slash key is not working on my MacBook (Leopard). I've tried every combo of keys and nothing works, restarted as well.

Took the machine to my local Apple store and in 30 minutes the keyboard had been replaced and it's all good. Except iSight and the Address Book now open on restarts.

Android keyboard setup question

I'm asking an Android question in these forums and if you don't think it makes sense, bear with me, it will... this is the kind of question I couldn't ask at an Android forum without expecting a lot of mud being thrown at me... mind you I try to stay away from flame wars and even though I do prefer the iPhone I wouldn't be (too) negative against other devices, unless they really don't work at all for me which is the case here. You can see this as a success story in favor of iOS...
I am and was always an iPhone user, but recently I got ahold of a few Android devices at my job for eh, job reasons (I'm an app dev). I'm supposed to have an Android as my work phone.
Which leads me to: I need to setup the Android device similar to how I always used my iPhone:s. I always use at least these three keyboards: Japanese (ten key), English, Swedish. Sure, I use some emoji keyboards and sometimes I play with other ones as well but those are my main ones I literally need without going insane, because I switch between them alot, all the time, in-sentence, and so on.
Trying to setup the same on an Android device has still proved impossible. Mind you I don't have a lot of experience with Android, but still... With iPhone, this always just worked and I never thought about it.
I actually do have access to a number of different Android devices, but the one I'm carrying with me is a Sony Xperia, currently at Android OS 4.0.4.
I'm living in Japan, and Sony seems to have made the decision to throw out the default/stock Android keyboard, and just provide something they call "Xperia keyboard", "Xperia Japanese keyboard" and "Xperia Chinese keyboard". This setup generally means I can only choose one keyboard like Japanese, and then use a single other one like English, OR Swedish. I can never have them all at once.
I know there are a lot of 3rd party keyboards out there, but popular ones like Swype etc does not support Japanese at all so that seems not a way to go...
I don't know if the default Android keyboard could pull this off - I haven't been able to turn it on or anything, and am reluctant to downloading a 3rd party keyboard claiming to be the stock keyboard for reasons like security and what-happened-to-the-out-of-the-box-experience.
My case is probably a bit narrow in a sense, but still, this should be easy, shouldn't it.
Any suggestions?

Here is how to do it in Android: http://android-developers.blogspot.com/2012/12/in-app-billing-version-3.html
How do I do it in Flash Builder?
An answer to this question and I'll start up development to a GPS coordinate game.

Q10 Keyboard Shortcut Question/Suggestion

I've entered several keyboard shortcuts. One of them is a person's name that I text regularly. The keyboard shortcut works in the body of a text, but not in the address field. Keyboard shortcuts should work in these fields also. I repeatedly text this person and don't want to start typing their name everytime. I want the three letter shortcut to automatically pull up the name.

The available keyboard shortcuts are also listed here in this forum, but that's not the user's question..

Keyboard backlight question and/or issue

When I am on a call after like 30-60 seconds the screen and keyboard dim and then go off. I am using a bluetooth but it also does this on handset audio when you do not press a key for a while during a call. I know this is normal. What I do not know is if the next part is normal. On the Tour the Green Talk key, menu, back, and red end key all stay lit up after the dim. I had to exchange my first tour and on this second one sometimes even the main row (green, menu, back, end keys) will dim so the entire keyboard is not lit up. That main row is lit up sometimes and sometimes not. Sort of like how the LCD dims sometimes and then the backlight will come back on for no reason like all blackberry's seem to do. Is my main row backlighting acting normal or is that row supposed to be lit the whole time and i have a short?

I too would love to know the answer to this question.
DJs use MB Pros under the same conditions, and I have heard from some that they have never experienced any issues after two years of intense use.
