Pressing the space-bar on a JTree results in TreeSelectionEvent.

Hello,
Have a JTree and a TreeSelectionListener that listens.
If the focus is on the tree and most of keys are pressed nothing happens.
However, if the focus is on the tree and the space-bar is pressed then the TreeSelectionListener.valueChanged(TreeSelectionEvent e) method is called.
How is it possible to know that the TreeSelectionListener.valueChanged(TreeSelectionEvent e) is called due to the space-bar press and not due to common tree navigation.
thank you,
Rami

Emails get sent in Mail when pressing the space bar whilst spell checking

Why do emails get sent in Mail when pressing the space bar whilst spell checking ?? This is beyond annoying. It's been happening for ages on my MBP. I have seen others complain and I can't understadn why this simple bug has not been fixed. Any help on this would be very much appreciated. thank you.

Hi
In composing I have Check Spelling "when I click send" selected. I tried on my iMac, my Mail account is sync'd via iCloud etc.. I got the same thing, when you hit send and review your spelling, I need to do that a lot, as well as insert missing words. As soon as you hit the space bar off goes the email. I have seen others complain of this on the google. I have now switched to check as I type but when i make a typo Mail just puts a red line under the word, it doesn't open up the Spell Checker dialog.
Is there away of resetting my Mail Apps database ? MAybe something is corrupt.
thanks.

First time I press the space-bar the text entry hangs for several seconds

Hi,
When entering text, the first time I press the space-bar the text entry hangs for several seconds.
From then on, there are no problems when entering text.
iPhone 3G, iOS 4.2.1, no automatic correction and no spell checking.
Thanks,

Didn't resolve the problem
There was some duplicated fonts fixed, but there wasn't the problem.
Right now i'm writin this in Firefox and here is fine. Couldn't do this in Safari.
I did make a video showing the problem.
Also strange is the fact that in some tabs there isn't (aparently) the problem in Safari.
Any other ideas?
Tks

Which is OS 10.7.x. Why does your system profile confirm you are actually using OS X Mountain Lion (10.8.4)? Please correct your system profile so that you will get the proper troubleshooting suggestions. Thank you.

Final Cut keeps blurring my footage even after processing it. It is in focus until I press the space bar...

I have just started a major project in Final Cut and I am having lots of issues with it.

If you make the Viewer the active window, and do a Shift+Z, does that help?
Are you seeing orange render lines in the Timline window?

I have created a table on pages. Somehow I have set something so a blue dot appears every time I press he space bar. How did I do it? and how do I get rid of it?

two questions-- I have created a table on pages. Somehow every time I press the space bar, I get a blue dot between words--How did I do it? and How do I get rid of it. Also, I created a template on pages--How do I "save as" for a new file using that template?

All you are seeing is the word space (from the spacebar).
Menu > View > Hide Invisibles you had Show Invisibles on.
When you are using a template it should be named "Untitled" and it will ask you to save when you go to close or you simply go to Save under the File menu.

Get the letter "B" after double tapping the space bar.

How do I stop the B? It's either hit or miss. Sometimes it happens, sometimes it doesn't.

VibrantRedGT wrote:
I wish it were that. Many times when I erase the B it comes back when hitting the space bar only once. The B is not really close to where I press the space bar either.
Then try the usual things:
1. Restart your phone.
2. Reset the settings (Settings > General > Reset).
3. Restore to factory settings.
If after step #3 you're still having problems contact Apple support and make an appointment at your nearby Apple Store to have it checked out.
If you have the problem with another device then I'm betting the problem is on the user-side and not the phone-side.

Beach ball when i hit the space bar

Hi All,
I have a song that freezes logic when i push the space bar to play. i open the song, cue it to the beginning, press the space bar and bam. spinning beach ball.
I've been working in Logic for about a year now and have finished dozens of songs and this is the first time I've had this problem. And this particular song is far less complicated then many others so i'm not sure what the problem is

What happens in a new user? What happens in Safe Mode? How about if you wipe the system, start clean and proceed from a clean OS before the migration? Any change?

On occasion the space bar will "click", but there will be nospace between the two words

At times and only occasionally when I press the space bar it does not perform the spacing between the two words.

As you probably know, the key is 'seen' by the computer when the two contacts touch. In the case of a key not working or working intermittently, there could be dust, dirt or cookie crumbs between the contacts. With the computer turned off, unplugged and the battery removed, carefully flip the computer upside down and give it a shake and be amazed at the amount of stuff that comes out of the keyboard. Try using a small vacuum cleaner on the keys. Try it again. If that did not fix the problem, you may need to get the keyboard replaced. As a temporary fix, consider using a USB external keyboard until you get the built-in one replaced.

What can I do to use the space bar as Hand Tool?

I'm using Photoshop CC and I could not use this tool pressing the space bar. Did this function change on CC version?
Thank you

Sometime it can be other applications grabbing the space bar, especially if you use Google Chrome browser which has been known to cause conflicts. See solution #2 on this link:

I wake up, unhibernate my laptop and suddenly I can't scroll by hitting the space bar, or clicking on the scroll bar itself, or even use the scroll arrows. In other programs it works fine. What happened and how do I fix this?

After hitting the space bar in Finder no Quicklook

On my Imac with OS 10.6.8 installed Quicklook stopped working completely. After hitting the space bar in Finder nothing happens at all. What could cause that problem?

Upgrading will NOT fix a problem. That needs to be resolved first to the point you have a stable system. I'd recommend doing a SMC and PRAM reset, if it doesn't work the first time you may have to do it 2-3x. Also restart in Safe Mode (hold down the shift key when you hear the startup gong and continue holding it until the progress bar appears).
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Why do none of the links that I put in my outgoing yahoo emails no longer underline themselves and become live when I finish typing them and hit the space bar?

Previously, when I typed my email address in an outgoing email or cut and pasted a link from my browser bar the link would become 'live' when I hit the space bar or 'enter' key. The link would turn blue and underline itself and the person receiving the email could just click on that live link and be taken to the site. Now the link does not turn blue or underline itself and the receiver must cut and paste the link into their browser bar to use it.
Why? I did not change anything in Yahoo or Mozilla.
I have deleted and reinstalled Java to no effect. I am using html in Yahoo.

As it turns out, many others have been having similar issues on other browsers. It seems that maybe Yahoo! is taking a much longer time to load or something like that. Either way, its been working on and off all week, and the same issue even showed up yesterday with IE 8 instead of FF. It still loads faster than IE 8, but again is spotty. Some people think the issue may be with mail.yimg.com or s.yimg.com, which I could see was the loading url in the left corner whenever Yahoo! Mail was refusing to work. A couple of people said blocking it caused the issue. Alternatively, some people suggested blocking it to solve the problem. Does anyone have any information on that? Again, I have no add-ons that would be blocking any urls, and my firewall hasn't any records of it. I really don't want to do anything to mess up my browsers more than they may have already been. Thanks for all of your help so far!
