Backspace

Hi, is there a way to backspace automatically without the user having to press backspace.
e.g.
int selection = inputting.nextInt();
while ((selection < 1) || (selection > 2))
selection = inputting.nextInt();
In the above code the user is forced to select either 1 or 2 and press enter. What I want is if the user presses anything but 1 or 2, it should delete the previous input(backspace), so the user can input 1 or 2 again. At the moment it goes onto a new line.
Thank You!

System.out.println(ascii_char_for_backspace)
I'll leave it for you to find out the ascii char.

Problem with backspace on JFrame

Hello,
I have a problem on a JFrame. Indeed, I add a keyListener to the frame, but the "Bakcspace" don't work. There is anything when a I press on Backspace (with KeyTyped, KeyReleased and KeyPressed). All other keys are working.
Thanks.

the solution of the problem is :
Version note: This page reflects the focus API introduced in released 1.4. As of that release, the focus subsystem consumes focus traversal keys, such as Tab and Shift Tab. If you need to prevent the focus traversal keys from being consumed, you can call
component.setFocusTraversalKeysEnabled(false)
on the component that is firing the key events. Your program must then handle focus traversal on its own. Alternatively, you can use a KeyEventDispatcher to pre-listen to all key events. The focus page (in the Creating a GUI with JFC/Swing trail) has detailed information on the focus subsystem.

Text Message incomplete or missing? Also-SMS editing / backspace malfunction...

First issue - sometimes I received text messages that are missing the last few words/characters. I don't think this is an Android or iPhone originated issue as this happens at random from people that I know have different types of phones. Sometimes the 160 character split will break up the message and send the rest in another message, but most of the time I never see the end of the message. I currently use the existing text messaging app in conjunction with the SMS pop-up. The issue was prevalent when I used Handcent and then uninstalled it to see if that was the problem. I have also uninstalled SMS pop-up to see if it was the problem with no luck. I have looked over the settings multiple times and still cannot find anything that would be causing this. Suggestions are welcome.
Second issue - when editing a text message in portrait mode I may erase multiple characters by holding down the backspace key. On occasion, the app flips out, reverts to showing the very first message that was sent or received for the contact, freezes momentarily, and then two buttons appear on the bottom giving me the option to Cancel or Delete. I will hit Cancel or use the back button on the bottom of the phone multiple times before it will return to my message, which at this point has saved as a draft. This is EXTREMELY frustrating. It does it only at random, but it seems to be getting more frequent. The only option most of the time is to go Home and then return to text messages, find my draft, and use the backspace key carefully (and one quick push at a time to erase) so as not to invoke the same issue.
I think both of these are bugs that may be inherent with this phone in particular or possibly Gingerbread...
Thanks!

I've been having this same issue for the past few months, in my case the problem seems to be more prevalent with text messages originating from other carriers (but not always, occasional partial incoming text issues from Verizon wireless phones as well). I called technical support, followed all their advice (basic tech advice, power cycle, remove sim, reboot, etc.) and was also transferred to HTC support that recommended a hot fix, which didn't really do anything to resolve the issue, also then did a factory reset and still no resolution. Not sure what other options I have....besides waiting for a new device when I am able to upgrade. Off topic, I think its Bee S to not be able to upgrade to a new device within 2 years, when Verizon does not fully support, properly updated/hotfix, existing issues in a timely manner...why is it that we are using and outdated OS, when a new one is out and available. Another compelling argument to purchase an iPhone (on any carrier), one device, one OS.....everyone gets an update at the same time, and phone issues are rapidly resolved. I can continue my rant, but I'll leave it as is...same issues, different day and I'm sure you've all heard the same rants of frustration.

CTRL_ALT-BAckspace not working in KDE4 [SOLVED]

Hi,
I use KDE4 (not modded) and have noticed recently that CTRL-ALT-Backspace won't work. I use it infrequently to jump to terminal mode so I'm not sure when this started. Is there a setting somewhere for KDE4 or KDM that I can alter or is this an issue with X???
Thanks

Android, backspace doesn't work properly in a flash.text.TextField

Hello,
I have a bug on my Nexus 5 Android 4.4 Air 4.0.
when I scroll the text in the textField and I select the text (in my example near "subclass" word), the TextField get focus, if I put on the backspace key, the character deleted is the previous character the first time, and if I put again on the backspace key, the caracter deleted is the first character and not the previous character.

How can I disable 'backspace' key from navigating back a page?

Several times over the last couple weeks, I type up a very well thought out response on Facebook in political conversations with friends. An hour or two into my work, I hit backspace with the intent of editing what I wrote (maybe after I scrolled or something, so maybe I unintentionally took the edit window out of focus). The navigator takes me back a page and I lose my two hours of work. Infuriating! Shortcuts with the ability to wipe out two hours of works should be disable-able. Not only that, I feel that is an unsafe shortcut for this very reason, and would have added a SHIFT modifier key or something like that. I think I invented a cool word: disable-able.

You can set the Integer pref browser.backspace_action to 2 on the about:config page to disable the backspace action. BTW Shift + Backspace does the reverse: going Forward if possible, so that is taken as well.

Apostrophes trigger weird backspace behavior in Mail

I upgraded to Mavericks a couple of days ago, and since then I've had the weirdest and most annoying problem in my Mail app (and ONLY in my Mail app):
If I type a contraction ending in "re", (example: we're, they're), the spacebar sends the cursor back one character instead of adding a space after the word. So, it deposits the cursor back beteween the "re".
If I form a contraction with any other letter combination (I'll, he'd, it's), the spacebar does nothing on the first strike. I have to hit it twice to get a space after the word. At all other times, the spacebar functions normally.
I've tried turning off spelling checks on my global keyboard preferences, and on Mail.app preferences; I've tried restarting the app and my MacBook. Nothing helps. And since I'm not a very formal writer, it bites me in the *** approximately seventy thousand times a day.
Is there any way to cure this disease?

Are you sure that the "smart quotes" box really fixed the problem? I have the same problem, but what happens is that when I type an apostrophe, it is at first a straight apostrophe, until I hit the space bar after the word in which I used it, at which time the straight apostrophe turns into a "smart" (i.e., slanted) apostrophe, and the cursor jumps back to the end of the word that was just autocorrected from straight to smart apostrophe.
Turning off smart quotes indeed prevents the backspace, but it does so by *not* turning the straight apostrophe into a slanted apostrophe. So yeah, it prevents the annoying backspace, but at the cost of functionality. How has apple not fixed this after all these months? Does mail just not misbehave this way for most people?

I need some assistance on stopping my backspace key from "sticking" on my iPad 2?

I have reset, restored, and rebooted. Nothing is working. My backspace key goes rogue even if I only hit it once. I've had this pad for 3 days and I'm a bit frustrated. I've noticed that the backspace key goes haywire in almost all third party apps but it also happens when I type email, calendar , events, and notes. The only way I can stop this from happening is to hit the spacebar multiple times or any other key on board. I am not new to Apple products as I have had several iPhones, iPod touches, and I had a Mac Book Pro for work. I have searched the communities and saw that this was an issue with earlier iPhones but I have not read anything to iPad 2. Any helpful assistance you can provide is appreciated.

I assume that you know if you hold down on the delete/back space key that it picks up speed and will rapidly delete sections of text as opposed to one letter at a time.
If you have restarted and reset (hold down the sleep and home buttons until the Apple logo appears) and have had no success, I can only suggest closing apps. Go to the home screen and double tap the home button to bring up your recent apps at the bottom. Tap and hold down on any app icon until they all wiggle. Tap the minus signs on the apps to close them. Close every app in the task bar. Tap the screen above the task bar and then restart the iPad.
I have no idea if this will help, but it can't hurt to try it. If your iPad is only three days old, I would also suggest a call to technical support. You get 90 days of phone support when you buy an iPad.

Programming backspace function in a java calculator.

I am doing a java calculator.
I want to program the backspace function, here is the code I have:
private void jbbackspaceMouseClicked(java.awt.event.MouseEvent evt) {
// TODO add your handling code here:
caja=Float.valueOf(jtfpantalla.getText()).floatValue();
if(caja==0){
jtfpantalla.setText("0");
else{
char caja2;
caja2=Float.toString(caja);
caja2.getChars(0,24,caja2,0);
jtfpantalla.setText(String.valueOf(caja));
Netbeans sends me 2 errors. I don't know how to use caja, as string or as an array. I want to convert it ,to print the characters of the array except the last character when the backspace button will be pressed.
I want to count the decimal point as another character, and print the characters except the last two when the decimal point is the penultime in the array.

I'd suggest that you store the temporary or displayed value in the calculator as a List of characters, or a String, and then don't ever turn it into a number until someone pushes the '=' button.
That's assuming I know what you're doing, which maybe I don't.

Backspace starts working as delete?

Hello,
Since two days ago I'm experiencing a very strange problem with my keyboard/OS. When I press the backspace button, the OS recognizes it as (forward) delete. Although, when I press backspace as some combination of button, it's recognized OK. I've checked the keyboard layouts (this also happens on foreign keyboard maps) and reset the keyboard shortcuts to defaults, but nothing changed. Furthermore, I have ControllerMate installed and it also reads a delete. I'd be very grateful for any ideas on what to do in this situation. Thanks!

And I think I answered my own question... I feel kinda dumb?
I've been creating new files inside the Paladin project. In any document in that project, that was included or that I created, the backspace key doesn't work. But, I created a new project and then some files within that and it works fine.
So, ultimately user error. But, weird for sure.
Thanks,
Gino

Hello, the 'Save As' dialog box used to allow the backspace button to go up one level in the directory when the focus is in the folder contents box but it does not work any more, please help.

Hello, the 'Save As' dialog box used to allow the backspace button to go up one level in the directory when the focus is in the folder contents box but it does not work any more, please help. BTW the same 'Save As' dialog in other applications still allow the backspace button to go up one level in the directory.

cor-el,
I kept forgetting and procrastinating about following your instructions, since I have internet access only for limited amounts of time and usually I am busy with important tasks when I am.
Out of the blue, the problem corrected itself (the Save As box started to open full screen, then shrunk down to a normal size and the edges can now be dragged to a custom size).
Even the copy and paste problem in the filenaming area seems to have been less troublesome lately even though there have been no updates to Firefox in a few weeks.
Even though I marked the solution as not helpful, the problem has in fact been resolved. I will save the solution instructions in case the issue returns.

Whenever i press backspace, the same thing that happens when i press 'ctrl + shift + I' happens

Whenever i press backspace, it does the same the same thing as if i press 'ctrl + shift + i', and again the same thing as if i press 'toggle tools' from the web developer option under tools from the menu at the top of firefox. I'm not a developer, i don't need this console thingy, and wouldn't mind getting rid of it. I didn't install it on purpose, and i have no idea what made this start happening recently. It's getting INCREDIBLY annoying.

The backspace key shouldn't be opening the Console.

When I use find, Firefox does not let me complete typing the word. Keystrokes effect the page as opposed to the find box (ex. backspace goes back a page instead of a character in the box). How do I fix this?

When I type in the Find box, Firefox interrupts me before I complete typing the word (usually in the first 4 letters. "Focus" moves from the Find entry box to the page itself. If I type backspace Firefox goes back one page of browsing, not one character in the box. I disabled Searchmenu, but that did not help.

Thanks for responding Chris.
I hadn't restarted after disabling SearchMenu. Having restarted, it would appear that the problem was, in fact, SearchMenu. Which was my suspicion. Once Find highlights a "word" SearchMenu interrupts to offer its services. I guess I'll post on their board, to see if there's a solution.
I should have restarted before posting. My apologies. Rookie move.
Thanks again, Chris.

Backspace in X apps

I ssh in to Solaris 10 boxes with PuTTY 0.60, and backspace works fine at the command line. In an X application, though, backspace and delete do nothing.

Yes. I'm forwarding X back to my PC, which is running Cygwin. The Oracle installer is my problem child. I tried with xcalc, and both backspace and delete clear the value in the window back to 0. Backspace works just fine in an xterm. The delete key is a little off in the xterm... it moves the character the cursor is on to the left, instead of replacing it with the character to the right as I'm used to.
