Jtextarea stays blank when typing in it

Hi all,
When I try to type into a Jtextarea, no text appears at all. The area stays blank.
I know it is there because I did a select all + copy, then pasted it into notepad and it was there.
Anybody had the same problem?
Thanks!

no...
i also tried revalidate() and repaint() and it didnot work...

Hi,
Did you make any changes to its Background or Foreground color ? It could be both colors are corresponding to each other, then you will not be able to see anything in it. If this is not the case, can you show me your code ?

Firestarter's hit list stays blank when portscanned locally

I have no real understanding of Iptables and just realized that after switching to AL I needed to set up some sort of firewall on my desktop.
So I pacman'd firestarted, found it in /opt/gnome/bin and ran the gui app
I set up everything according to how I wanted it to act and then dropped it down into KDE's tray.
I hopped over to one of my other local computers and scanned it with nmap and Xscan and both turned up blanks. Thats great... but Firestarter's hitlist is staying blank. Not a single notification has popped up as it should, the home LAN has numerous M$ and *nix boxes.... and our public IP is scanned quite regularly by kiddies out there....
Is there some configuration I need to carry out? I've read the manual at Firestarter's homepage and drew a blank.
Anyone seen this behavior with firestarter? It will stay running on the comp as its keeping my desktop slightly less vulnerable but I'd really like to gain full functionality from the program.
If ya'll need any more information please don't hesitate to ask... Or a URL to go read at... I've drawn a blank on google and linuxquestions.org....
Appreciate any replies,
James

I use normal iptables logging (the LOG chain) [from gShield (PKGBUILD available on the forums)] and I redirect all my kernel output to vc12 from within syslog-ng. I could create a filter for those messages in syslog-ng to show, for example, the firewall messages on vc11, but haven't looked in the configs yet.
Or, now I've thought of something else. You can create a FIFO with mkfifo and pipe all the firewall messages to that (also using a filter in syslog-ng). Let's assume you've created it with
mkfifo /var/log/iptables_pipe
Config your syslog-ng (I don't know if syslog is so flexible) to redirect iptables messages to /var/log/iptables_pipe (I can't tell you how to do this, because I haven't tried it yet).
Do (in a console)
while read line; do echo $line; done < /var/log/iptables_pipe
and you'll have live report from iptables.
^ I think this should work, but haven't tested it yet (as I've said).
Good luck.

P.S.1. There are some more advanced programs (as far as I remember) for detecting intrusions on Linux. I don't remember these advanced programs having a GUI, probably because they're enough complicated on the inside to create an interface for them. They just put the output in a log, you follow it whatever you want. You won't see much interactivity from the Linux firewalls, mostly because they were supposed to just sit on a machine and do their work.
P.S.2. I haven't seen on linux a GUI firewall on linux doing popups and so on. This is probably because the components are well defined, the firewall runs as root and you probably log in as a normal user. Allowing a normal user to modify live the firewall rules creates a security hole.

The back, forward, reload and stop buttons are greyed out, the address bar stays blank when I go to a website and firefox loads to a blank page, not my home page. There are 3 users on this computer and it only happens on one user.

Firefox loads to a blank page, not my home page. When I click on the home button it takes me to the home page. The back, forward, refresh and stop buttons are greyed out and not usable. The webpage I am on does not show up in the address bar. If I type something into the address bar, that address stays there no matter what page I go to next.

Just upgraded to v4. It did NOT fix the problem.

How can I prevent my previous login strings from showing when I starting typing. I'd rather the field stay blank and not start to fill in, based on previous entries.

I don't know what setting to change so that when I start typing my login (to an email account, etc), the previous entries do not show up. I want the field to start out and stay blank, and have me type the whoe string

I am having exactly the same problem right now. After some research, it looked like my HD was toast. I replaced it today, that part was easy, but now I cannot seem to use my original Install Disk to format the new HD. I get a grey restart screen, or if I get to the Language Selection screen, my cursor is frozen in left corner and I can't use it.
Very frustrating, hope someone else has some ideas!
PS My MacBook was about same age, and "expired" in exactly the same way as yours.

It could be the work of one of your add-ons, or even add / mal-ware.
Look thru your add-ons list and make sure you know what each one is

My iTunes is asking me to fill in 3 questions but when I tap on the first question the pop up screen stays blank!!! Any help...

When using my new ipad I am trying to download an app,when I press install it is asking me to fill in 3security questions...when I tap on first one it just stays blank! Can anyone help?

Hey herbthewelder,
I'd give these troubleshooting steps a try, they're for when your iPad appears frozen or unresponsive:
If the device is unresponsive or certain controls aren't working as expected, try restarting
To turn off the device, press and hold the Sleep/Wake button until the red slider appears.
Slide your finger across the slider to turn off the device.
To turn on the device, press and hold the Sleep/Wake button until the Apple logo appears.
If the device remains unresponsive or does not turn on (or power on), try resetting
Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds.

IBooks stays blank - cannot add files to library

My iBooks library is simply blank. I cannot see the files I 'added' to the library. I cannot see the files it supposibly imported from my iTunes (which now no longer has a 'Books' section.
Even tho i can open pdf's on my iPhone 5 just fine, none of those files can be seen anywhere in iBooks on my Macbook Air (Maverick), even tho iCloud i enabled and works fine in all other apps.
When i try to add files to my library it asks me if i want to replace the files they match that are already in it (again, these files cannot be seen), but it makes no difference whether i tell it yes-replace or no-cancel at that point: my iBooks stays blank.
I cannot uninstall iBooks because it says it is required by OS X.
When i open the app, view its info or try to delete it my whole laptop laggs.
Someone please please help. I haven't been this frustrated with a computer since i was still using pc's

Satellite Pro P100 - Screen stays blank

Computer seems to be on, but the laptop screen stays blank.
Ok so right now the power light is on and HD and the back fan is not on, and when I press the power button, the HD and the back fan comes on and then the power light just flashes, but nothing is on the screen, and the the keyboard lights (capslock/numlock etc) do not flash like they would on a boot up. That leads me to assume that the laptop is hibernating or something, but it should come out of hibernation (if it was) on a press on the power button, but nothing happens when I do that.
also connected an external monitor to the back of the laptop, got nothing on the screen as well.
any ideas?

Hi
Hm, it could be a mainboard issue or something else. I doubt that its a problem of the internal display because tested an external display and there you can notice the same issue.
What you can do is this following workaround: Remove the battery and AC/DC adaptor and then wait one hour. Connect the AC/DC adaptor and battery again. Now you can try to start the notebook again.
If it doesnt work I would ask a notebook technician from an authorized service provider. Maybe its a hardware malfunction and the ASP can test your notebook.
Bye

Samsung 205BW goes blank when using DVI

Hi
I have a G4 Mac Mini. I recently purchased a [url="http://komplett.ie/k/ki.asp?sku=322266"]Samsung 205BW 20in widescreen LCD monitor[/url].
I connected it via the DVI port on my mini with the DVI cable that came with the monitor and it seemed to work great but occasionally the screen will flick black as if there was nothing connected to it. It happens most noticeably when I go from a fullscreen quicktime video to the desktop or if I activate Expose. Also if the Mini goes to sleep and I try to wake it the screen stays black and I either have to reboot or change to using the VGA cable.
The monitor works perfectly if I use a DVI-VGA adaptor and connect to the VGA port on the monitor but I'd prefer to use DVI.....
I read on here of people using SwitchResX to change the settings for the monitor. I downloaded it but I don't really know what to input in the custom settings... perhaps someone here can help?
Here is the DDC file from SwitchResX:

I had the exact problem you report with my core duo Mac Mini connected to a Syncmaster 204B. This problem persisted when I returned the monitor several times to Samsung for replacement 204B's. They eventually upgraded me to a refurbished 204T and the problem disappeared.
It seems to me that Samsung has some real problems with screen blanking when their monitors are hooked by DVI to certain Macintoshes. For anyone contemplating a Samsung monitor, I'd recommend another brand until it's known that this screen blanking problem has been resolved with all Samsung models.

Mail ok in preview and blank when tapped

My mail accounts were working fine until 2 days ago. I've done nothing different. Now I can see mails as they arrive in preview in the inbox but the message is blank when opened. If I then open it in Outlook it's fine. It doesn't seem to be displaying messages and I can't write messages either for same reason. Help anyone?

Hi Weird Exactly the same thing happened to me! But I am worried I will lose other info/data/settings if I try the reset trick - or will everything stay as is except (hopefully!) my mail issue will be fixed?!! Thanks
