JComboBox Dropping Problem

Hi, I have a JComboBox in a table cell with all the Item I need. But the problem is when I click on JComboBox, dropdown menu pops up and immediately hides automatically. And cannot allow me to choose anything.
Any suggestions plz.
Thanks

You've got a coding problem, so read this section from the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html]How to Use Combo Boxes for example on how to do this correctly.

Drag and drop problem on Lion... doesn't work

Hi,
I have had a drag and drop problem since I installed Lion on my computer. I grab a file and by the time i try to drop it on a folder it is not released. This happens in all programs and it is really annoying, finder, iphoto, mail, you name it.
I've tried repairing disk permissions directly from lion and then from the repair disk partition and it has been no good.
Any ideas???

Drag and drop problem from wizard inside another drop

I am using JDK 1.5.0_11 Swing.
I am facing a Drag and Drop problem which is described below:
A drag and drop operation invokes a wizard, from which another wizard is invoked. Within one of the panels of this 2nd wizard, I am trying to do a drag and drop from a JTextarea to a JTree node, but am NOT able to. I am not getting any exceptions. I have written a transfer handler for the JTree node to handle the text transfers from a JTextArea. When I try to do a drag and drop from a JTree node to another JTree node I'm getting the 'InvalidDNDOperation: drag and drop in progress' exception.
When the 2nd wizard is invoked directly, I am able to do the drag and drop from JTextArea to a JTree node and also from a JTree node to another JTree node.
I tried spawning a new thread for the 2nd wizard, but am still unable to initiate drag and drop.
Should I be spawning a new thread for the 1st wizard?

Displaying something other than a list in a JComboBox drop down section

Dear all,
i'd like to be able to put a JTree into a JComboBox drop down section, or at least appear to have done this. has anyone done this or have an idea how this might be achieved?
Cheers,
Matt

Sounds like a job for a custom renderer. The JTree tutorial shows an example of one.

DWCS3 Float Drop Problem?

My site passed the Browser compatibility check in DWCS3, however, after launching site online and viewing it on a IE6 PC computer, the home page does not display correctly: the center section drops down. I checked for a potential float drop problem by adding up my widths including margins and padding: Sidebar left is 170 px, main content area is 370 px (this is the area that drops), sidebar right is 180 px = 720 px. The container is 780 width so I don't understand why the center doesn't fit but drops down because there seems to be 60 px left in the overall width to provide plenty of room. The main content area doesn't have a width specified, just a left and right margins (left set at 170 and right set at 180). I didn't try a conditional comment because I am not that familiar with coding. Any suggestions would be helpful. Also, don't understand why this wasn't flagged in the DWCS3 Browser compatibility check when it scanned for IE6. The address is http://www.eastontroop66.org and it's the home page. Thank you!

Pls Help! Drag and Drop problem, identical symbols acting differently - same code! WHY?

In the attached file, I have a series of symbols that have a drag and drop command to change colour at different sections of a bullseye, and that are also text editable (html).
However, some of the symbols get stuck and will not be moved after moving once or at all, and some get stuck once their text has been edited.
I have poured over the code and it appears to be the same for each symbol - can anyone explain as to why this is happening?
I also cannot now edit the text properly on the ipad (it is really fiddly to change between different symbols to edit their text -- is there maybe a better way to do this? A button to change between symbols to then edit their text, can you help with this too?)
THANK YOU SO MUCH!!!

Has any one found a fix for the iOS 5 WI FI dropping problem?

I own an iPhone 4 and when I upgraded to iOS 5.1.1 it began dropping the WI FI connection randomly, usually after only a few minutes of inactivity. The only solution is to re-start my router and it works fine for a while then drops the connection. I am certain the problem is not with the iPhone hardware. It must be a bug in iOS 5.1.1.
I have been an apple user since the beginning and I have owned just about every model of Mac, I hope Apple will address this issue soon, as I can not imagine any way end users can fix the problem. For the record; my iPhone is factory fresh and not hacked in any way.
Thank you in advance for any assistance...

I'm not aware of any wifi drop problem, which leads me to believe that your router is the problem (or your wifi carrier). Have you had problems using wifi at a public location, like a coffee shop or any store that provides free wifi?

10.5.2 failed to fix wireless connection dropping problem

10.5.2 did not fix wireless connection dropping problem. I lose wireless connection whenever my MBP restarts or wake up from sleep in the building where I am and have to retype password about 10 times a day. I had not had this problem when I used Tiger. Everyone who has upgraded to Leopard or has it installed on their Mac is experiencing the same problem. Is there any solution or trick to resolve this problem? Thank you.

Amularya,
Please read the post I made in this thread earlier. No less than a dozen solutions are offered in the link I provided for wireless issues. Troubleshooting wireless issues requires individual attention because of the plethora of issues which can't be tested for. So please start a new topic thread here:
http://discussions.apple.com/forum.jspa?forumID=1225&start=0
So you can get a wider audience, and won't confuse the original poster with solutions that don't apply to them.
There literally hundreds of different WiFi adapters.
Dozens of different virus and firewall combinations.
Possibilities for damaged WiFi cards and routers, as well as routers whose firmware is not to spec with the latest wireless standard.
To top it off, bad RAM, hard disk being too full, and bad preference, cache or or logfiles can make various aspects of the operating system misbehave, and/or even the directory leading to those files.
Until each person starts their own thread looking for solution individually, chances are they won't find one. Yes, 10.5.2 addresses WiFi for some people. Obviously it doesn't for everyone. The point is, there are some people, like myself who have never had a WiFi issue either with Intel or PowerPC Macs that they couldn't resolve without a little bit of troubleshooting. I'm happy to help you walk through it, but only if you start your own thread asking for help.

Update 2, if it can help someone:
Finally I don't manage the drag and drop by myself using
DragManager.doDrag(...). Why? Because doing so if the user clicks
on the scrollbars, on the datagrid header or on an empty row, it
triggers the drag start and that is ugly. By letting Flex managing
the drag and drop process, this doesn't append. BUT I was unable to
use a custom proxy image then. Until I found this article:
http://www.dgrigg.com/post.cfm/11/03/2006/DataGrid-Drag-Image
The trick is:
1) save the mouseX and mouseY using the mousedown event.
2) override dragImage(), as the article says, to create your
custom proxy, attaching to it a FlexEvent.UPDATE_COMPLETE event,
saving it to a class variable and returning it.
3) When you receive the FlexEvent.UPDATE_COMPLETE event, you
update the proxy position (that is saved in a class variable) using
the saved mouseX and mouseY and you remove the listener to the
event:
When you drop the proxy, you access the dragged items in :
event.dragSource.dataForFormat("items")
Hope this helps, I spent lot of time trying to resolve this
issue! Now it works perfectly! :-)

ASHA 210 SIGNAL DROP problem

I purchased a nokia asha 210 but am experiencing signal drop problems. I lose signal bars very very frequent;y. I would be glad if some one can direct me in resolving this issue.
Shivam

To rule out the phone,how old is your sim card,if its older than one year i suggest you change it.If you try your sim in another phone and the same issue occurs its your sim card.
If i have helped at all a click on the white star below would be nice thanks.

Signal drop problem in Asha311 network mode is kep...

Hi All,
I just purchased new Asha 311. i just noticed one strange thing. If phone network mode is kept on "Dual mode"
I am facing signal drop problem after every incoming or outgoing call ( same the case with SMS ). when we keep network mode in "GSM" mode there is no problem at all.
is anybody facing that problem.
guys please suggest what should i do ? . is it a problem in cell phone.
Regards,
amit kushwaha
Solved!
Go to Solution.

When you select the dual mode the device will try to find the 3G connection. If the strength of 3G is adequate it will connect and when the strength falls it switches to GSM. Now if you are in an area where 3G is available but the signal strength is not that good, it will constantly switch between 3G & GSM. That leads to problem. Keeping phone in GSM mode forces it to stay that way & ensures constant connection. If you have 3G activated, then you can force the device to stay on 3G by selecting that mode. Please note that the coverage area of GSM in some places is more than 3G so you may get no signal on 3G but it may be present in GSM mode.
Please mark the post as solution if it solves your problem.

**Fixed** WRT54GS V6 - Intenet drops problem/router stoped responding

The important parts:
Windows XP SP2
WRT54GS V6
Motarola Cable router.
So after 3 days on the phone with Tech Support and 2 senior advisor's, they officialy gave up... or they say they will get back to me
Heres the problem:
Everything was working fine until one day one day the internet connection on my WRT54G v2 decided to stop working, after trying everything i could, and connecting directly to the modem, i concluded it must be the router, and after owning it for 3 years, went out to by a new one, WRT54GS.
Take it home, open it up, same problems... Internet works for about 30 seconds, then drops again for good. I can restart/reset the router, again it will last for about 30 seconds then drop again. The router itself after these 30 seconds cannot be pinged or connected too.
Tech support says to return it and get a new one, maybe it was defected....i did, now router #3 same problem, keep in mind that the network still works, just the internet dosnt. I upgraded the firmware with tech support on the phone, tried just about every troubleshooting technique they could possibly try,(Power cycle, pinging, renewing, upgrading firmware, changing ip, changing to half duplex...)you name it iv tried it and still no internet, btw, im connected via wire to the router, wireless experiance same problems with other computers.
So im kinda hopeing someone had same problem? Any idea's will help. please god! Thank youMessage Edited by helfandeli on 01-18-200712:02 AM

Try resetting the router to factory defaults, using the procedure below. Hopefully this will get you access to the router so you can update your router settings.
1)  Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4)  Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button, click on "Run". In the box that is labeled "Open:", enter the following: "ping 192.168.1.1" (no quotes). A black box will appear. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out."   If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, then in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
If you get this far without problems, try the setup disk, and see if you can get your router set up and working. When you get to the password prompt in setup, be sure to leave the user name blank.
If you have a problem, note the exact error message and the status of the lights on the router, and report back.
Hope this helps.

Need help with IE6 box drop problem DW CS4

Having a problem with this page: http://www.recoverings.com/tarzan.html in IE6. Maincontent drops below the sidebar menu. Looks fine in FF, Safari, IE7.
All other pages work well. I assume that this has something to do with the width of the .wrapnail and .thumbnail divs, but reducing the margins doesn't seem to help and the images start to get too close together. What am I missing here?
Can someone help me solve this?
I would also appreciate any suggestions on cleaning up my CSS. Seems like I have an awful lot of stuff in there. Maybe it's okay but could it be cleaner?
Thanks for your help,
Phil

IE bug Float Drop is fairly common. Make sure your page wrapper division is wider than the combined width of left sidebar + main content + left & right borders if any. If that doesn't help, add an overflow: hidden rule to your floated container and make sure you have cleared both floats.
More about float drop and the expanding box problem can be found here:

Drag & Drop Problem

Hi,
I've got a drag and drop pyramid and the aim is to drop words
in to the correct section of the pyramid. The problem is if the
target area for one of the drag objects is the bottom section, then
you cannot have another drag object to go to that section. anyone
know a way around this, or how to use the same taget for more than
one object.
thanks
