JButton and JComboBox problems!!!

I have a program that has a bunch of different panels, and each of those has panels in it and soforth. Several levels down the line I add a JPanel that has a JComboBox, some JButtons and a JTextField. The textfield works fine: you can type in text, etc. However, I cannot click the JButtons (when you mouse over them, they change color appropriately, but clicking does nothing visually, and the ActionListener does not catch anything). In addition, when clicked, the JComboBox displays in a totally inappropriate area!!! (see screenshot below)

Any ideas?

However, I cannot click the JButtons (when you mouse
over them, they change color appropriately, but
clicking does nothing visually, and the
ActionListener does not catch anything).Make sure you have added the ActionListener to the JButton, and provide implementation for the actionPerformed() method.

JButton and JComboBox

Hi,
I'm having problems with my comboboxes. Basically, I need that after I press a button, it would take what's selected in the combobox and pass it to database. What would be the sample code for that. Do I need to add ActionListener or ItemListener to the combobox. I'm a little confused with those.
Thank you

That's not really how you implement an actionlistener. Whenever the JButton is clicked the actionPeformed method of your actionListener is called. The way you have it set up, you parse what's in the combo box once and then repeatedly send this value off to the database everytime the button is pressed.
And making a component static just to access almost always constitutes as a bad idea. You can make the DataEntryButton an innerclass. Alternatively you can declare a field in the class and pass along the combo box.
public DataEntryButton implements ActionListener {
     JComboBox semesters;
    public DataEntryButton(JComboBox semesters) {
        this.semesters = semesters;
    public void actionPerformed(ActionEvent event) {
         int semester = Integer.parseInt((String) semesters.getSelectedItem());
        //and then I send it to DB
}

JButton and exception problem

Hi all,
I created a JButton, named open _DB, and add an ActionListener to this. I want that when I click the button the methods in the loop executed (see below for code). However, I always get exceptions. How can I catch these exceptions?
If I use a try-catch loop I got the error:
ModelClipTest.java:559: ';' expected
public void actionPerformed(ActionEvent e)
ModelClipTest.java:559: missing method body, or declare abstract
public void actionPerformed(ActionEvent e)
How can I solve this problem. Can anybody help me?
Thanks
Murat
//CODE
open_DB.addActionListener
(new ActionListener()
public void actionPerformed(ActionEvent e)
try
ifcdemo = new IFC_Demo();
ifcdemo.execute();
IFC_RelFillsElement_Query.query_fill(ifcdemo);
IFC_RelVoidsElement_Query.query_void_ids(ifcdemo);
IFC_BuildingStorey_Query.query_buildingstorey(ifcdemo);
} //CLOSE TRY
catch(Exception ex)
System.out.println("Exception caught");
System.out.println(":-(");
} //CLOSE CATCH
);

yes, sorry. However, I still get these exceptions for the methods inside.
What should I do to get rid of these exceptions?
Thanks.

Java Audio Metronome | Timing and Speed Problems

Hi all,
I’m starting to work on a music/metronome application in Java and I’m running into some problems with the timing and speed.
For testing purposes I’m trying to play two sine wave tones at the same time at regular intervals, but instead they play in sync for a few beats and then slightly out of sync for a few beats and then back in sync again for a few beats.
From researching good metronome programming, I found that Thread.sleep() is horrible for timing, so I completely avoided that and went with checking System.nanoTime() to determine when the sounds should play.
I’m using AudioSystem’s SourceDataLine for my audio player and I’m using a thread for each tone that constantly polls System.nanoTime() in order to determine when the sound should play. I create a new SourceDataLine and delete the previous one each time a sound plays, because the volume fluctuates if I leave the line open and keep playing sounds on the same line. I create the player before polling nanoTime() so that the player is already created and all it has to do is play the sound when it is time.
In theory this seemed like a good method for getting each sound to play on time, but it’s not working correctly.
At the moment this is just a simple test in Java, but my goal is to create my app on mobile devices (Android, iOS, Windows Phone, etc)...however my current method isn’t even keeping perfect time on a PC, so I’m worried that certain mobile devices with limited resources will have even more timing problems. I will also be adding more sounds to it to create more complex rhythms, so it needs to be able to handle multiple sounds going simultaneously without sounds lagging.
Another problem I’m having is that the max tempo is controlled by the length of the tone since the tones don’t overlap each other. I tried adding additional threads so that every tone that played would get its own thread...but that really screwed up the timing, so I took it out. I would like to have a way to overlap the previous sound to allow for much higher tempos.
I posted this question on StackOverflow where I got one reply and my response back explains why I went this direction instead of preloading a larger buffer (which is what they recommended). In short, I did try the buffer method first, but I want to also update a “beat counter” visual display and there was no way to know when the hardware was actually playing the sounds from the buffer. I mentioned that on StackOverflow and I also asked a couple more questions regarding the buffer method, but I haven’t received any more responses.

Any help getting these timing and speed issues straightened out would be greatly appreciated! Thanks.

JBuilder 8 and GUI Problems

I have an abstract base class that extends JFrame. It's not in a package and is directly in my project.
The base class has some JPanels, JButtons, and JLabels. I create a class and derive from the base class, and the derived class adds a JButton and a few private methods. Everything compiles fine and
the program runs fine.
The problem is when I click F12 to go into designer mode for the derived class to view the GUI, I see a red dialog with the name of the base class in the upper-left corner, and this message in the bottom of the IDE:
Failed to create live instance for variable 'this'. null
Failed to create live visual subcomponent this as BaseFrame(cls); creating a red component in its place
I've tried everything, and have the latest JBuilder8 patch.
Can anyone help with this? I have seen one other person on the web with the same exact problem, but he got zero responses indicating it's probably difficult to solve the issue.

I found out why this is happening, but I don't yet know how to fix it. It's a start.
The reason the derived class does not show the JFrame in the Design mode is
that the base class is an abstract class. When I remove the abstract keyword
from the base class, it works and I can view the JFrame in Design mode for the derived class.
Now to figure out how to keep the base class abstract and still have design mode work.

Strange JComboBox problem

I have a weird JComboBox problem that has me stumped. I am dynamically changing the contents of a JComboBox after creation. When the change function is called it removes all existing contents from the JComboBox and then repopulates it. It is really straight forward. The strange thing is that it is working perfectly under Windows 2000 with JRE build 1.3.0, but with Windows XP I end up an empty JComboBox. I don't even know where to start debugging this. Any ideas?
Thanks

I notice the same problem... with no solution for the moment...

Colors of JSpinner and JComboBox

hello
I like to change the fore- and backgroundcolors of JSpinner and JComboBox. how can I do this?
thanks in advance! nix

this is much easyer code I will use it.
but the button is anyway gray and black!?You want to change the color of the arrowButton and arrow color?
there's probably an easier way, but this worked OK for me

Question
I am not able to launch FF everytime i try to open it, it says FF has to submit a crash report,and restore yr tabs. I even tried doing that and the report was submitted too, but still FF did not start, and the problem still persists, please help me solve this issue
'''(in English)'''

Hi Danny,
Per my understanding that you can't get the expect result by using the expression "=Count(Fields!TICKET_STATUS.Value=4) " to count the the TICKET_STATUS which value is 4, the result will returns the count of all the TICKET_STATUS values(206)
but not 180, right?
I have tested on my local environment and can reproduce the issue, the issue caused by you are using the count() function in the incorrect way, please modify the expression as below and have a test:
=COUNT(IIF(Fields!TICKET_STATUS.Value=4 ,1,Nothing))
or
=SUM(IIF(Fields!TICKET_STATUS=4,1,0))
If you still have any problem, please feel free to ask.

BOSD, Battery issues and Heating problem after iOS 8 upgrade

i have upgraded my iPad mini to iOS 8. Ever since I upgraded to iOS 8 am facing blue screen issues and heating problem as well. This is really frustrating even the patch iOS 8.0.2 dint solve the problem. Are you guys listening our complaints. When will you fixing it.

The same thing happened to me on my 2012 Subaru Outback. I'm not sure this will help you since you have a Honda, but I'm posting this just in case.
I paired the audio on my car with my iPhone 6. However, when I turned the car off and back on again, the iPhone would not pair automatically. I had to manually connect the iPhone with the car. Turns out there are two separate bluetooth pairings on my car: one for phone which allows up to 5 devices and one for audio which allows only one device. So I did the second bluetooth pairing for the phone (had already done the audio), and that fixed it. YMMV

I am making code to try to make a game and my problem is that my code......

I am making code to try to make a game and my problem is that my code
will not let it change the hit everytime so im getting the first guy to hit 1 then next hits 8 and so on and always repeats.
Another problem is that I would like it to attack with out me telling it how much times to attack. I am using Object oriented programming.

          System.out.println("RockCrab hit: " +instance2.done);
          System.out.println("rockCrabs health: " + instance1.health);
}when the code is run it says something like this:
you hit 1
RockCrabs health is 9
RockCrab hit 7
your health is 38
you hit 1
RockCrabs health is 8
RockCrab hit 7
your health is 31
you hit 1
RockCrabs health is 7
RockCrab hit 7
your health is 24
you hit 1
RockCrabs health is 6
RockCrab hit 7
your health is 17
my point is whatever some one hits it always repeats that
my expected output would have to be something like
you hit 1
RockCrabs health is 9
RockCrab hit 9
your health is 37
you hit 3
RockCrabs health is 6
RockCrab hit 4
your health is 33
you hit 2
RockCrabs health is 4
RockCrab hit 7
your health is 26
you hit 3
RockCrabs health is 1
RockCrab hit 6
your health is 20

Remote and IR Problem

A rather odd and annoying problem has recently been occuring on my MBP. A couple days ago my remote (after working without fail for over a year now) suddenly stopped working. Yesterday night and this morning it started working again but after a while it stopped again. I've read dozens of support articles which haven't really helped because there seems to be another problem.
Most articles have stated that there is an option to disable the IR receiver in the "security" window under system preferences. When the IR and remote are not working this option disappears but when they are working the option is present. I have also tried replacing the battery without any result.
I am now thinking that it might have something to do with heat buildup because it is mainly occuring after the laptop has been on for about a half hour, so I am going to try to borrow someone's fan.
If anyone has any suggestions to solve this I would appreciate it if you could help. Thanks!

check out this thread. Seems to be the same problem.

LG Ally text message and gps problems

hello. ive been with verizon for about 10 years maybe. ive been overall happy with the service and customer service. but the prices should be alot lower.lol. i started out with the motorolas then switched to the lg phones. only problem with the motorola was the speakers. not loud enough. could never hear the phone ring. the lgs usually suffer from the same problem.
i had a few phone problems but nothing like this lg ally. im on my second one and about to be my 3rd one in about 3 months. 1st phone i had every problem under the sun. this phone i am suffering from text message problems and gps problems. i suffer from what everyone else has problems with. the messages wont send. they will eventually lock up. it will show the envelope with the red explanation point ( i think thats the graphic). then usually everytime when i sent a text the texts will close. it will send then bounce back and show up as a draft and i have to resend it and wait for it to go thru. finally the last problem with the texts. when i send a text a phone number from my contacts shows up and freezes on the screen. its in white text with a black background. its the same number every time. it stays on the screen until i restart or pull my battery out.
gps. when i open up google gps that comes with the phone i make sure the gps is on... when the directions are found and the map pops up 9 out of 10 times it just keeps saying searching for gps. the turn by turn never is found. the 1 time it does it takes a good 10 minutes to be found. atleast on my first one ally the gps did work 8 out of 10 times. it just took a good 5-10 minutes for gps to be found and show turn by turn.
anyone else have these problems? where you able to fix them or did you need to get a new phone? the 2.1 update was supposed to fix problems. i think they just made it worse. the ally is supposed to have 2.2 froyo. where is it. is it ever going to get it. i got this phone because i like the lgs and the keyboard. also the sales representative on the phone was giving the lg ally rave reviews. why couldnt he say dont buy this go with a motorola droid. this phone is the biggest junk ever made

I do apologize you are having trouble with your device I looked in our information system on the LG Ally in reguards to issues you are having it states if you have the Free Droid Security anti virus protection application down loaded it will cause the phone to lock up or freeze. Check and make sure you do not have the application on your device. Check you GPS settings and make sure correct. Go to Settings; Location & Security; make sure GPS is on wireless network. If this does not fix issue you can try doing a Master Reset on your device. Make sure your contacts are saved in your G-mail account or through Back Up Assistance.
Master Reset/Soft Reset:
Factory Reset option 1
From the main screen, touch menu tab
Touch Settings
Touch Privacy
Touch Factory Data reset
Touch Reset Phone
Warning: This will erase all data from your phone, including:
Your Google account
System and application data and settings
Downloaded Applications
It will not erase: Current System software and bundled applications; SD Card files, such as music or Photos
Factory Reset option 2 - Warning this will reset device back to original factory settings.
Turn off the phone
Press and hold "home" + "end" + "volume up or down" keys together for a few seconds when the device is power off
Once device displays boot information, release keys.
Soft Reset
Press the Power key.
Touch Power off.
Touch OK.
Press the Power key to power on the device.
or
Remove battery cover, remove battery and reinstall.Also there is a new update for LG Ally it will be the Froyo 2.2 but there is not release date available at this time it will post on your device when available. Hope this Helps. Leslie

Hi b,
Have you restarted yet?

How do I fix my ipod classic that says very low batter after I have charged it and the problem persists?

I have an Ipod video 30g that says Please wait very low battery. I charged it for about a day and the problem persists. I've tried using some solutions on the internet and none of them worked including: holding the menu and select, holding select and play to put it in disk mode with no avail. Is there anyone who can help me!!!

Have you read this post written by another forum member?
The Sad iPod icon.
However, as your iPod was purchased on Boxing Day, why not get it serviced under the warranty?
You can arrange online service here.
Service request.
Or if an Apple store is near you, take it there and have them check your iPod.
You can make an appointment by using this link.
