How to "listen" to a disabled JCheckBox?
Hi,
I have a checkbox that I'd like to behave as follows.
Initial state (enabled and de-selected)
1st click - selected (as normal)
2nd click - remain selected (but disabled)
3rd click - de-selected and re-enabled (back to initial state)
My action listener is able to perform these basic tasks.... but I can't figure out how to get the action event to fire while the JCheckBox is in the disabled state. That is to say, when the JCheckBox is disabled, clicking on it does not fire my ActionListener.
How do I override this and fire the ActionListener? Custom Action? If so, I don't know how to override the appropriate methods. Any advice is appreciated! Thanks in advance...
Thanks for the responses.
I want to avoid having 21 sets of triple radio buttons (Currently have 21 checkboxes) as my UI doesn't have the real estate for this. And it would be overwhelming to look at.
The checkboxes are used for inclusion criteria to narrow down data based on 21 boolean fields. I don't actually want to disable the checkboxes, I simply want to make them look different, grayed out being a very nice distinction. My intention is for checked (+enabled) to mean include logic, checked (+disabled) to mean exclude logic, and unchecked to be ignore logic (aka OR).
At the moment, I recheck the checkbox upon the second click and change the label. I'd rather not change the label but instead change the component's appearance. I like the disabled look for this purpose.
Can I gray it out without disabling it, then?
Alternatively, can I add a separate MouseListener to "listen" to clicks on the checkbox, and programmatically only perform an action if it meets my criteria (disabled)?
Surely there's a workaround...?
Thanks again.

How do you grey out/disable fields under a radio button if another radio button is selected in Adobe Acrobat XI Pro?
I’m creating a form where the user has three options to make a payment.
1. charge to my credit card
2. charge associated costs to bank account
3. By cheque or money order
My Problem is, under each option, there are required fields that has to be filled out. So if the user picks the first option, charge to my credit card, they would fill out the required fields (credit card number, expiration date etc.). But when they click submit button to submit the form, it won’t let them, because there are required fields under the second option. Also, I have the radio buttons for the three options setup so that if the user holds the shift key and clicks a radio button, it unchecks it. So what I'm trying to do is this: If the user selects the radio button for option 1, the other two options are greyed out/disabled. And if the user holds down the shift key and clicks radio button for option one again, it unchecks the radio button and the other two options are available again. Is there a way to grey out or disable the two other payment options when the other one is picked. I’m assuming I will have to use javascript, but what would the coding be and which field do I write it under?
Thanks in advance guysYou will have to use custom JavaScript to access the various properties of the field object.
The radio button group has a value. When no button is selected that value is "Off". When an individual button has been selected the value for the group will be the option or export value for that individual button.
Once you have determined the button selected, then you will know the form fields that need to be made required. You use JavaScript to access those fields and change the "read only" property to false, and set the "required" property to true. For the fields associated with the other options, those fields should be reset, made read only, and have the "required" property set to false.

>> Also, I have the radio buttons for the three options setup so that if the user holds the shift key and clicks a radio button, it unchecks it.
Radio button in a PDF do not work that way. Only check boxes can be unchecked by clicking on one that has been checked.
If you plan the coding for the Mouse UP action to test for all possible options and code for each of those options you should have what you want.
If you want actual code you need to provide a lot more details.
It is even possible to perform some credit card and bank routing number validations with JavaScript and some check digit formulas. -
How do I use GarageBand as a amp/speaker to listen to my Electronic Drum set? I have a MIDI-USB cord already but I can't figure out how to listen to my set through the software using my computer speakers?
If you want to listen to the sounds of your drum set, you should use an audio cable and connect it to the computer's line-in, then create a real instrument track.
If you use a Midi/USB interface, you'll have to create a software instrument track and select one of GB's drumsets as the instrument. Hopefully your drumset's midi notes are mapped to the right sounds in GB. -
When I upgraded from 3.XX to 4.0.1, it informed me that 2 extensions were not compatible and it never gave me the option to remove them. Firefox 4.0.1 disabled them and now I'm not able to remove them.
Also they were added by Acrobat Pro X (Adobe Acrobat - Create PDF 1.0) and Nokia Ovi Suite (Firefox Synchronisation Extension 7.3.4.51).
These extensions won't probably be updated unless they update the software that installed them. With this said, How can I remove the disabled extensions? Why it doesn't give me a button to remove them to start with?I think it's not the problem of compatibility. Extensions installed into Windows registry won't have a remove button ( or it's greyed out ). For these extensions, you can have a look into these keys:
HKEY_CURRENT_USER\Software\Mozilla\Firefox\Extensions\
HKEY_LOCAL_MACHINE\Software\Mozilla\Firefox\Extensions\
If you are under a 64bit OS as I am, you may also try this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mozilla\Firefox\Extensions\
And you may find the registry entries corresponding to the extensions you want to remove. Just export them to a backup.reg, then delete these entries. Firefox will do the rest, but it seems that fx still leaves extensions.rdf untouched. You can also delete the RDF entries corresponding to those extensions inside extensions.rdf
cf: http://kb.mozillazine.org/Uninstalling_add-ons#Windows_Registry_extension
BUT the Wow6432Node key wasn't mentioned in the above article
I had to search the registry to find out the entry corresponding to a Fiddler2 extension, then I found the Wow6432Node key. I also saw the Nokia Ovi Suite entry beside the Fiddler2 entry.
Hope it helps. -

How can i reset my disabled iphone to factory setting without itunes?
how can i reset my disabled iphone to factory setting without itunes?
When you made the backup, you may have told it to encrypt the backup so that you can recover iPhone to factory settings successfully.
http://support.apple.com/kb/HT1414
Therefore I used the normal iTunes backup and restore found under the Summary tab in iTunes. If your data is still on the other phone, back it up again with iTunes. To use iTunes you have to start it, connect your phone to the computer with a cable, then select the iPhone button near the top right corner of the screen. Be sure not to check the encrypt button. -

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.
