I need to disable key events - J2ME

Is there anyway, in J2ME, to disable key events while processing a current key? I want to avoid queing up of key events and then re-enable key events when I am done handling the current key.
public void keyPressed(int keyCode) {
switch (keyCode) {
case -50:
// I want to disable key events here
// process this key
// re-enable key events
break;
default:
break;

I had tried using a boolean to skip avoid the key as you suggested. That does not work. It seems as if the keys are only being processed in a serial manner. By that I mean the keyPressed method is not receiving the second and third keys while I am processing the first. So when I am done processing the first key I set isOkayToProcess=true and then the second key comes in.

  • Disable key event

    Is there a way to disable keys from being pressed?

    With current technology, you can't prevent the user from pressing keys, but you can ignore any key presses that they make. Here's a handler that will make your movie ignore everything except vowels:
    on startMovie()
      the keyDownScript = \
    "if "&QUOTE&"aeiou"&QUOTE&" contains the key then"&RETURN&\
    "    -- Let the key press be treated"&RETURN&\
    "  else"&RETURN&\
    "    stopEvent"&RETURN&\
    "  end if"
    end
    If the #keydown event is stopped then no sprite or member will receive an indication that a character has been typed.
    You might like to look at the keydown event handler and build your own custom solution.

  • I need to disable the delete key from going back a page.

    My son is doing online homeschooling. If he is taking a quiz and accidentally hits the delete key to correct a word in his answer the page goes back and he is kicked out of the quiz. I need to disable this function in Safari to protect him from this. Please help.

    HI John,
    That would require remapping. This thread has some links available that may help.

  • Need key events in JPanel

    I can't receive key events in a JPanel, and need to figure out how. While the JDialog I added my JPanel to originally could catch these, once I added more components (like a JTextBox and JCheckBox), neither my panel nor dialog caught any key events at all. Isn't there some way when my panel has focus to capture and respond to key press events?
    Thanks,

    This works for a JFrame, didn't test it on a JDialog:
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    public class PanelEvents extends JFrame
         public PanelEvents()
              JPanel main = new JPanel();
              main.setPreferredSize( new Dimension(300, 300) );
              main.setFocusable(true);

  • How to disable the F4 Key Event?

    Hi Guys,
    I have written my own FocusManager which allows me to traverse through disabled components. If a user presses the F4 key while the focus is in a disabled JComboBox, the popup becomes activated. Is there any way deactivate the F4 keystroke?
    I have tried:
    event.consume();
    combobox.setPopupVisible(false);
    combobox.hidePopup();
    I also read that F4 is a low-level event maintained by Windows. Is this true? Is there no alternative?
    -Sri :)

    To anyone who may be interested:
    I have tried all available solutions:
    1. hidePopup()
    2. setPopupVisible(false)
    3. unregistering the F4 key event
    4. catching the F4 key event and snubbing it
    I have had no luck with the above solutions. It leads me to believe that F4 key is registered under the windows environment and it is a low-level event.

  • Is there Key Event in J2ME?

    Hi there,
    Is there key event in j2me? It seems we only can get event from Command.
    By the way, there is only few messages in KVM disscussion home. I thought J2ME is getting more popular recently, So we should have more people in Forum.
    However, Microsoft put more on WinCE; and Qualcomm has BREW for wireless device. Do you think Java will win?

    why don't you look in the specs B4 posting.

  • Adobe reader control kills key events

    I am using visual studio express 2013 on Win7 professional (x64) to write a private c# form application.
    Adobe reader is installed and added to my project.
    The control shows a pdf, wounderful.
    But at the moment, my form has the adobe reader control, no key events where triggered.
    Without the control: all works fine.
    I record a video to show my problem: https://www.youtube.com/watch?v=V0Vo2p2jz9M
    Is there a solution or workaround to give the key events to my form?
    Are more information needed?
    Thanks a lot.

    Check if you have full access to
    HKEY_CLASSES_ROOT\AcroExch.FDFDoc and sub keys,
    Disable any antivirus or backup applications while installing Reader.

  • Sleutel Bind, fancy key events handler for standalone window managers

    I began using Openbox in my laptop a while ago, and I was amazed by the speed, customization and simplicity it provides. After I started customizing my desktop I noticed that some of the special keys (TouchpadToggle, Volume, PrintScreen, etc) didn't worked at all. There are some applications for the Volume keys to work, but not for keys like touchpad-toggle and print-screen. Of course, there's a workaround for each case using simple scripts, but I wanted something a little more fancy, so I made:
    Sleutel Bind
    It's made in C and provides key events handling for:
    XF86TouchpadToggle
    Print (prtsc key)
    It makes use of libnotify to display states ( touchpad enabled/disabled, screenshot taken, etc) and imlib2 (a very popular library, probably already installed in your system) to grab the screenshots. Almost all other keys are covered already by another application, but if needed, more key events will be added in the future.
    Feel free to post your thoughts about Sleutel Bind, it's my first contribution to the community.
    How to use
    Once installed just run the command as a normal user.
    If using openbox, place the following command in the "~/.config/openbox/autostart" file:
    sleutelb &

    Do you still have issues with the latest version? Otherwise I will mark this thread as solved.
    well, still do not work... But I do not want to try it any more...So you can mark.

  • Unable to find Key Events when there are multiple Commands

    Hi,
    I've developed a simple J2ME Appln containing 3 commands
    for ex- Exit,Help and Info(all with same priority).
    As there are 3 commands, Exit command is present at the left and the other two namely Help and Info have been listed under Menu and this Menu command is presented at the right.
    My MIDlet class has extened MIDlet and implemented CommandListener. Using CommandAction(), I'm able to generate action for Command press and i've also created a nested class which extends Canvas so, using keyPressed and keyReleased, I'm able to find the Key Press Events.
    Now, my appln needs to find just the key press events. After i press the Menu command, the two commands namely Help and Info are listed. In tht screen, I need to find out whether any other key events are being generated but my keyPressed and keyReleased are not being called.
    Please provide me solution ASAP.

    I'm going to make a few assumptions:
    1. The menu you're describing is the automatically generated one caused by having more than two commands.
    2. The subclass of Canvas is the currently active Displayable (otherwise you won't get any key events at all).
    If this is the case (and someone correct me if I'm wrong), key events are being handled by the phone's subsystem to drive the menu, which means there's no way to get them. The way I've approached this kind of problem is to create my own menu painting and handling code and incorporated it into the Canvas. Then, make one Command called 'Menu' and have it invoke your custom menu code.
    I realise this isn't an ideal solution, but it's something.

  • Can  DISABLE preProcess Event Handler add to the Orchestration parameters?

    I have a DISABLE pre-process event handler defined on the User object. I need to set the current date on a USR UDF attribute whenever the user is disabled or enabled or created. The CREATE handler works and the date value shows up on the user profile. However, when I try to set this attribute on the pre-process DISABLE or ENABLE event handlers, the new date does not show up. Here is the code I am using in my DISABLE/ENABLE event handler:
    Date currentTime = new Date(System.currentTimeMillis());
    orchestration.addParameter(USER_STATUS_DATETIME_ATTR_NAME, currentTime);
    Where the orchestration object is from the execute() parameter list.
    Any ideas as to why this is not working? Is adding to the orchestration not allowed for DISABLE or ENABLE event handlers? I know my handler is getting calls as I am logging the orchestration.getOperation() value.
    Thanks for any suggestions.

    When you update the field, make sure you are using the field label name, and not the UDF value.

  • Macbook misses some key events for a few seconds

    I have noticed that for last two months or so something strange happens to my Retina MBP. Once in a couple of days it stops responding to some key events. It is like it handles only one keypress out of 4-5. Nothing seems to be wrong with the keyboard and it is not about a particular key or keys. And about 10-15 seconds later everything goes back to normal. I do not see any suspicious messages in the logs, the computer is connected to the power supply...It happens just by itself in the middle of the day, when I am typing.
    Almost looks like some interrupts get lost by the system while it is busy with something else. But I have checked the load level and running processes - nothing interesting there....And whatever it is - it happens during a very short period of time.

    Hi,
    No, I have not returned my MBP yet. In fact, I would rather avoid doing this unless I am convinced if it is a hardware issue. And I do believe it is not. Just recently I have spent some time investigating it and I have found very stroing correlation between the moments when this happens and these messages in the kernel log:
    Jan 13 10:49:54 mbp-wifi kernel[0]: Sandbox: sandboxd(96471) deny mach-lookup com.apple.coresymbolicationd
    Jan 13 10:54:31 mbp-wifi kernel[0]: Sandbox: sandboxd(96499) deny mach-lookup com.apple.coresymbolicationd
    Jan 13 10:54:31 mbp-wifi.home sandboxd[96499] ([96497]): mdworker(96497) deny mach-lookup com.apple.ls.boxd
    Jan 13 10:54:31 mbp-wifi.home sandboxd[96499] ([96498]): mdworker(96498) deny mach-lookup com.apple.ls.boxd
    Jan 13 10:56:32 mbp-wifi.home sandboxd[96504] ([96503]): mdworker(96503) deny mach-lookup com.apple.ls.boxd
    Jan 13 10:56:32 mbp-wifi.home sandboxd[96504] ([96502]): mdworker(96502) deny mach-lookup com.apple.ls.boxd
    And I have also noticed that my Spotlight database gets reconstructed too often, which means it gets corrupted.
    From all this I conclude that it is most likely the software issue and it seems to be linked to spotlight. I saw people reporting similar things. So now I am researching on how to fix it without disabling the spotlight.
    In general, I believe that the quality of Apple software is going down, it is not like 4-5 years ago And Apple does seem to care less and less about it.
    If in your case it happens all the time, not just once in a while, and you see that a particular key has problems - it is possible that we are talking about the different issues and yours might be really about the keyboard.

  • Detect key events on anything

    If I have a JFrame with many components on it, how do I detect if a key is pressed, without having to add a listener to every component? For example, how can I check for the escape key being pressed, but not having to have componentN.addKeyListener(this); for everything?
    Thanks
    US101

    The correct way to collect the key events is the following:
    from java 1.2 to java 1.3 use the FocusManager. This class can be found in the javax.swing package. You would then need to extend the DefaultFocusManager and override specific behavior.
    for java 1.4 use the KeyBoardFocusManager. This class can be found in the java.awt package.
    Please see the following for a better explanation:

  • KEY events in MIDlets

    Hello all,
    I am basically new to J2ME MIDP development and also new to this
    forum. So apologies if this has already been covered or turns out to
    be a stupid question :) Here goes:
    I am trying to develop a MIDlet where I have a Form to accept certain
    values from the user. This is fairly straightforward and is easy to
    create with the high level Form a and TextField objects.
    Now, I wish to add a functionality to my MIDlet, in which, the user
    can press a specific key.. say the "Select" key or the "Call" key.. at
    any time during the form to start another thread of operation which
    performs something totally different... say for example, the user is
    entering values into the form and in between somewhere he presses this
    specific key and the phone start playing music. I hope you get my
    point.
    Basically I want to listen for key pressed or key held events on a
    Form object. Now I understand that Key events can be found only on the
    low-level Canvas based UIs. So is it possible to do it with Screen class
    elements..?
    Thanks,
    Nik

    You can try to use a CustomItem. What events will be delivered to the custom item depends on the implementation, though. Also these events will be only delivered when the CustomItem is focused.
    Have a look at the J2ME Polish GUI for using CustomItems for MIDP/1.0 devices as well.

  • 2nd JFrame at Full Screen not registering key events

    I've written an application that launches other applications distributed as JARs with a particular method (replacing the main method). These other applications run at full screen.
    Whilst I have got these other applications to work in that they display correctly and do everything else, I require them to register key events. If I run these applications on their own (i.e. having not been launched by the primary application) then the key events are processed correctly. However when they are launched from the primary application the key events are not registered.
    I have tried requesting focus from the full screen JFrame but it doesn't seem to be able to.
    Any ideas?

    Possible that the keystrokes are really being trapped by the other gui, which stops registering them when it's not visible.
    IF that's the case, you'll need to re-design your keyboard trap as part of the second JFrame, wholly independent of the original JFrame or originating app. Also, it may be thread-starved i.e. operating off the originating program, which thread may be stopping when it has no focus.
    That's all the ideas I have.
