  • input type="email"

    - by Charles
    I have a form where I ask for email addresses. Usually I'd use <input type="email" ...> but I want to allow a user to type foo rather than [email protected] in the (likely) case that they are using an @mycompany.com email address. Is there a way to get around the validation (if format matches this regex, accept; otherwise, validate normally), or should I just use <input type="text" ...> and ignore the semantics and so forth?

  • How to make a UITextField move up when keyboard is present

    - by philfreo
    EDIT: Over 1k views with 3 upvotes? If this question is helpful, vote it up :) With the iPhone SDK: I have a UIView with UITextFields that brings up a keyboard. I need it to be able to: Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up Automatically "jump" (by scrolling up) or shortening I know that I need a UIScrollView. I've tried changing the class of my UIView to a UIScrollView but I'm still unable to scroll the textboxes up or down. Do I need both a UIView and a UIScrollView? Does one go inside the other? [EDIT: I now know that you want a UIView inside of a UIScrollView, and the trick is to programatically set the content size of the UIScrollView to the frame size of the UIView.] Then what needs to be implemented in order to automatically scroll to the active text field? Ideally as much of the setup of the components as possible will be done in Interface Builder. I'd like to only write code for what needs it. Note: the UIView (or UIScrollView) that I'm working with is brought up by a tabbar (UITabBar), which needs to function as normal. Edit: I am adding the scroll bar just for when the keyboard comes up. Even though it's not needed, I feel like it provides a better interface because then the user can scroll and change textboxes, for example. I've got it working where I change the frame size of the UIScrollView when the keyboard goes up and down. I'm simply using: -(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height - 215 + 50); //resize } -(void)textFieldDidEndEditing:(UITextField *)textField { //keyboard will hide scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height + 215 - 50); //resize } However this doesn't automatically "move up" or center the lower text fields in the visible area, which is what I would really like.

  • Enable/disable virtual keyboard

    - by dr.Xis
    I'm using a virtual keyboard. I have a checkbox that controls whether the virtual keyboard is displayed or not. The thing is that I don't understand how to disable it. I try to unbind it but it doesn't work... I also tried to use namespaces and then unbind all namespaces but still the keyboard remains accessible after a click on the text box. <input class="virtualKeyboardField ui-keyboard-input ui-widget-content ui-corner-all" data-val="true" data-val-required="The User name field is required." id="loginUserName" name="UserName" type="text" value="" aria-haspopup="true" role="textbox"> <script type="text/javascript"> $(function () { //show login $("#showLogin").on({ click: function () { $("#loginFormDiv").toggle("slow"); } }); $("#cb_showVKey").on('click', CheckIsToShowKey); }); function CheckIsToShowKey(event) { //var isCheck = $("#cb_showVKey").is(':checked'); //alert("ischecked? " + isCheck); if ($("#cb_showVKey").is(':checked')) { //if checked BindKeyboards(); } else { //not checked UnBindKeyboards(); } } function bindVirtualKeyboards() { $("#loginForm").delegate(".virtualKeyboardField", "click.xpto", BindKeyboards); } function UnBindKeyboards() { $("#loginForm").undelegate(".virtualKeyboardField", "click.xpto", BindKeyboards); } function BindKeyboards() { // alert(event.currentTarget.id); //alert("xpto"); if ($("#cb_showVKey").is(':checked')) { $("#loginUserName").keyboard({ layout: 'qwerty', lockInput: true, preventPaste: true }); $("#loginUserPassword").keyboard({ layout: 'qwerty', lockInput: true, preventPaste: true }); } } $(document).ready(function () { $("#loginForm").validate(); BindKeyboards(); }); </script> Any help guys?

  • /dev/input/uinput Device appears to be 'broken'

    - by Adam Luchjenbroers
    I'm trying to setup Pystromo so that I can remap the keys on my Belkin N52TE gamepad. Pystromo basically captures the key strokes and then outputs the remapped keystrokes to the uinput device. However, at the moment it simply swallows the input and outputs absolutely nothing. I've tracked the issue to something being wrong with my uinput device, with the smoking gun being: # ls -l /dev/input/uinput crw-rw---- 1 root plugdev 10, 223 Dec 31 2009 /dev/input/uinput # cat /dev/input/uinput cat: /dev/input/uinput: No such device The uinput module is loaded, and can be clearly seen via lsmod. Anyone seen this before, or can think of something worth attempting? Current Setup Gentoo Linux Kernel 2.6.32 (Gentoo Sources 2.6.32-r1) HP DV7 Laptop Output dmesg dmesg | grep uinput does nothing, and no new lines appear if I run modprobe -r uinput && modprobe uinput. Yet the uinput module can clearly be seen when running lsmod: # lsmod | grep uinput uinput 6200 0 lsusb # lsusb Bus 005 Device 003: ID 050d:0200 Belkin Components Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 002: ID 1532:0101 Razer USA, Ltd Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 5986:0143 Acer, Inc Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 002: ID 03f0:171d Hewlett-Packard Wireless (Bluetooth + WLAN) Interface [Integrated Module] Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub lsusb -v PasteBin Update Hmm, updating evdev and hal seems to have partially fixed it. /dev/input/uinput still can't be accessed but Pystromo is now remapping keys successfully. I'm a little bit mystified about what's going on here, but it seems that my understanding of how all this works is flawed. Since I've posted a bounty, I'll leave this here for someone to post an explanation for how user-space input devices work under the hood.

  • Kernel Error during upgrade or update commands

    - by Ashesh
    I am getting these errors during sudo apt-get update and upgrade... I tried all possible options no success. I recently upgraded to 13.04 and had problems with Broadcom WiFi.

  • What makes games responsive to user input?

    - by zaftcoAgeiha
    Many games have been praised for its responsive gameplay, where each user action input correspond to a quick and precise character movement (eg: super meat boy, shank...) What makes those games responsive? and what prevents other games from achieving the same? How much of it is due to the game framework used to queue mouse/keyboard events and render/update the game and how much is attributed to better coding?

  • Can you restrict the location of input type=file?

    - by dcp3450
    Is there a way to restrict the user to a folder on the server when they choose to browse for a file using the input type=file button? for example: If you have images you want the user to choose from that only exist in the server's image folder to prevent them from search for and uploading their own images.

  • Should the function or the caller be resonsible for input validation?

    - by haudenschilt
    I'm doing a security audit on a fairly large php application and was wondering where I should include my user-input validation. Should I validate the data, then send the clean data off to the back-end functions or should I rely on each function to do it's own validation? Or even both? Is there any standard or best-practice for this sort of thing? Currently the app does both inconsistently and I'll like to make things more consistent.

  • Why is Gnome-Shell thinking my "d" key minimizes all windows?

    - by Limitless
    I am on Ubuntu 12.04 LTS (in gnome-shell) and I am unable to use my "d" key. Regular gnome-2 works perfectly fine, but for some reason I cannot use my "d" key in gnome-3. I recently installed it and have been trying to figure this out, but I have no clue what's going on. I attempted to disable the keyboard shortcut that minimizes active windows, but that did not work. (My only option right now is to use CTRL-V to paste my "d"s.) On top of this, my arrow keys automatically move my windows and I cannot move through text using them. What's going on here, folks?

  • Working with Lightweight User Interface Toolkit (LWUIT) 1.4

    - by janice.heiss(at)oracle.com
    Vikram Goyal's informative and practical article, "Working with Lightweight User Interface Toolkit (LWUIT) 1.4," shows developers how to best take advantage of LWUIT 1.4. LWUIT is a user interface library designed to bring uniformity and cross mobile interface functionality to applications developed using Java Platform, Micro Edition (Java ME). Version 1.4 offers support for XHTML, multi-line text fields, and customization to the virtual keyboard.Goyal notes in the article that, "Perhaps the most important feature of this release is the ability for LWUIT to support XHTML. Specifically, it now supports XHTML MP (Mobile Platform) 1.0, a version of XHTML designed for mobile phones. To be even more specific, it now supports CSS styling for the HTMLComponent within the LWUIT library through Wireless Application Protocol CSS (WCSS)." Read the entire article here.

  • Difference in fans on Windows 7 and Ubuntu 12.04

    - by Timo
    I have bought a Hp Pavilion DV7 with Core i7 CPU and installed Ubuntu 12.04 on dual boot with Windows 7 alongside. Apart from the difference in battery life (although that's fixed with Jupiter), I have another problem with the fans. On Windows my fans work perfectly and the laptop is cool, but it seems to overheat in Ubuntu. It becomes quite hot and it looks like my fans are not working under Ubuntu. I think I'm having the same problem as How can I keep the cpu temp low?, but since I cannot comment because of the lack of reputation (?), I post the question as a new thread. I think the result of the overheating is that my keyboard doesn't seem to follow when I start typing a long text. It just freezes and types the last letter multiple times. For example: when I type the word freezes, it shows freeeee so the zes changed into eee...

  • '6' key stuck when outside the graphical interface

    - by Felipe Jacob
    A strange thing has been happening since I installed Ubuntu. Whenever I'm not on the graphical interface, that is, if I do ctrl+alt+f2, or while the system is shutting down, or when I try to reset my password accessing root on security mode, the '6' key seems to be stuck. This doesn't affect my day-to-day usage at all, but whenever I change from the graphical console, I can't do anything because it keeps pressing '666666...'. Does anyone know why that might be happening? My keyboard is a Logitech G710+, and hasn't shown any other possible compatibility issues.

  • Detecting extremely fast joystick button presses?

    - by DBRalir
    Is it usually possible for the player to press and release a button within a single frame, so that the game engine doesn't have time to detect it? How do programmers usually handle this situation? Is it even necessary to handle it? Specifically, I am asking about GLFW's joystick input capabilities. I am currently using GLFW to make a game, and I've noticed that keyboard and mouse have callback functions, while joysticks do not. Also, it does not appear to be possible to enable "sticky keys" for a joystick. (I have only recently started using GLFW, so please correct me if I am wrong, as having either of those would solve the problem.)

  • Wifi function key not working on HP laptop

    - by lopsided98
    I have an HP Pavilion g7-1260 with Ubuntu 13.10 on it. I would like to be able to use the wifi toggle key on the keyboard to enable and disable wifi. My wifi works fine and the light on the key turns on when I enable wifi through the Ubuntu networking menu. The problem is that pressing the key does not do anything. It should be activated when I press fn + f12. I tried using xev to see if an event was generated but there wasn't one. I also tried the same thing with apci_listen but it didn't output anything. Does anyone know how to get the key to work?

  • How to specify which keys CapsLock affects?

    - by Seattle Jörg
    Using Maverick, I am not able to get the CapsLock behaviour I want: I would like it to affect essentially the alphabetical, numerical, and punctuation keys, i.e. all the keys that print something (as opposed to, say, the error keys), but only them. To illuminate this with an example: when writing code that uses % as the symbol for a comment, I want to be able to position the cursor at the start of a range of lines I want to comment out, then hit CapsLock, then iteratively hit the 5 key (using QWERTZ, Shift+5 gives %) and the arrow down key, so that I can quickly place a % at the start of the lines. Ubuntu in default configuration takes CapsLock literally, so that it affects only alphabetic keys. Under Preferences/Keyboard/Layout/Options I can make it act as a pressed Shift, but then the action of the arrow keys is to select text. All the other options available are equivalent to one of these two in my case. Is it possible to somehow get this behaviour? This is standard in Windows.

  • Text reverses on remote gnome session

    - by Andrew Stern
    I have two computers running 10.4 . The first machine is a wired desktop with sshd. The second is a wifi connected laptop with the ssh client. When I use my laptop to bring up a remote gnome session to my desktop all the text gets reversed. Steps: 1) login as a user on the laptop to activate the wifi with a stored key. 2) goto a console Ctrl-Alt F1 3) do a xterm -- :1 to bring up a blank graphic session 4) ssh -Y user@desktopmachine gnome-session This shows reversed text and messes up the keyboard so I can't type
