  • Create an UIButton with "push button" appearance?

    - by Krumelur
    I want to create a button with the same look and feel as the "Timer" function in the builtin Clock app, but it really eludes me how to do it. By looking at the source code for UICatalog, it seems to create these buttons you need to create a custom bitmap. Is this true? If so, is there a "standard" bitmap that can be used, to ensure consistent user experience?

  • jqTouch - why does the transition has no animation?

    - by teepusink
    Hi, I'm using jqTouch. Trying to figure out why when the scene / div change, it just change abruptly without the slide animation? Here is the setting that I have now: var jQT = new $.jQTouch({ slideSelector: '.link', useAnimations: true }); Again the scene change works just fine, just that I don't see the slide animation. What am I missing? Thanks, Tee

  • Java Socket Connection is flooding network OR resulting in high ping

    - by user1461100
    i have a little problem with my java socket code. I'm writing an android client application which is sending data to a java multithreaded socket server on my pc through direct(!) wireless connection. It works fine but i want to improve it for mobile applications as it is very power consuming by now. When i remove two special lines in my code, the cpu usage of my mobile device (htc one x) is totally okay but then my connection seems to have high ping rates or something like that... Here is a server code snippet where i receive the clients data: while(true) { try { .... Object obj = in.readObject(); if(obj != null) { Class clazz = obj.getClass(); String className = clazz.getName(); if(className.equals("java.lang.String")) { String cmd = (String)obj; if(cmd.equals("dc")) { System.out.println("Client "+id+" disconnected!"); Server.connectedClients[id-1] = false; break; } if(cmd.substring(0,1).equals("!")) { robot.keyRelease(PlayerEnum.getKey(cmd,id)); } else { robot.keyPress(PlayerEnum.getKey(cmd,id)); } } } } catch .... Heres the client part, where i send my data in a while loop: private void networking() { try { if(client != null) { .... out.writeObject(sendQueue.poll()); .... } } catch .... when i write it this why, i send data everytime the while loop gets executed.. when sendQueue is empty, a null "Object" will be send. this results in "high" network traffic and in "high" cpu usage. BUT: all send comments are received nearly immediately. when i change the code to following: while(true) ... if(sendQueue.peek() != null) { out.writeObject(sendQueue.poll()); } ... the cpu usage is totally okay but i'm getting some laggs.. the commands do not arrive fast enough.. as i said, it works fine (besides cpu usage) if i'm sending data(with that null objects) every while execution. but i'm sure that this is very rough coding style because i'm kind of flooding the network. any hints? what am i doing wrong?? Thanks for your Help! Sincerly yours, maaft

  • Clickable TextView in Android

    - by Cris
    i'm building an Android App that has many many TextView that i want to be clickable. I've tried to assign to the single TextView the properties android:clickable="true" and android:onClick="clickHandler" and when the app fires the clickHandler(View v) i correctly get, through the v.getId(), the clicked item. What i don't like is to define, for every TextView, the properties android:clickable and android:onClick ... is there something that i can do by code to say: "all the textviews are clickable and click is handled in 'clickHandler' ?" Thanks and greetings c

  • Can someone explain this 'double negative' trick?

    - by ProfessionalAmateur
    Hello, I am by no means an expert at javascript, but I have been reading Dave Pilgrim's "Dive into HTML5" webpage and he mentioned something that I would like a better understanding of. He states: "Finally, you use the double-negative trick to force the result to a Boolean value (true or false)." function supports_canvas() { return !!document.createElement('canvas').getContext; } If anyone can explain this a little better I would appreciate it!

  • On Click alert if $.get returns a value, if not, submit the form

    - by bradenkeith
    If the submit button is clicked, prevent the default action and see if the field 'account_name' is already in use. If the $.get() returns a result, alert the user of the results. If it doesn't, submit form with id="add_account_form". My problem is that my else{} statement is not submitting the form. I get no response when submit is clicked & there is no value returned. Also I would like to change my code where it goes $("#add_account_form").submit(..) instead of .click() however, would that cause a problem when trying to submit the form later in the script? <script type="text/javascript"> $(document).ready( function () { $("#submit").click( function () { var account_name = $("input[name=account_name]").val(); $.get( "'.url::site("ajax/check_account_name").'", {account_name: account_name}, function(data){ if(data.length > 0){ confirm( "The account name you entered looks like the following:\n" +data+ "Press cancel if this account already exists or ok to create it." ); }else{ $("#add_account_form").submit(); } }); return false; }); }); </script> <p> <input type="submit" id="submit" class="submit small" name="submit" value="Submit" /> </p> </form> Thanks for your help. EDIT So anyone who runs into my problems, it's that $.get() is asynchronous, so it will always return false, or true depending on what submitForm is defined as. $.ajax() however, allows async to be set as false, which allows the function to finish before moving on. See what I mean: $(document).ready( function () { $("#add_account_form").submit( function () { var submitForm = true; var account_name = $("input[name=account_name]").val(); $.ajax({ type: "GET", async: false, url: "'.url::site("ajax/check_account_name").'", data: ({account_name: account_name}), success: function(data){ if(data.length > 0){ if(!confirm( "The account name you entered looks like the following:\n" +data+ "Press cancel if this account already exists or ok to create it." )){ submitForm = false; } } } }); if (submitForm == false ) { return false; } }); }); Thanks for your help @Dan

    I have this form: class Request_Form_Prova extends Zend_Form { public function init() { $this->setMethod('post'); $SubForm_Step = new Zend_Form_SubForm(); $SubForm_Step->setAttrib('class','Step'); $this->addSubform($SubForm_Step, 'Chicco'); $PrivacyCheck = $SubForm_Step->createElement('CheckBox', 'PrivacyCheck'); $PrivacyCheck->setLabel('I have read and I agre bla bla...') ->setRequired(true) ->setUncheckedValue(''); $PrivacyCheck->getDecorator('Label')->setOption('class', 'inline'); $SubForm_Step->addElement($PrivacyCheck); $SubForm_Step->addElement('submit', 'submit', array( 'ignore' => true, 'label' => 'OK', )); } } That generate this HTML: <form enctype="application/x-www-form-urlencoded" method="post" action=""> <dl class="zend_form"> <dt id="Chicco-label">&nbsp;</dt> <dd id="Chicco-element"> <fieldset id="fieldset-Chicco" class="Step"> <dl> <dt id="Chicco-PrivacyCheck-label"><label for="Chicco-PrivacyCheck" class="inline required">I have read and I agre bla bla...</label></dt> <dd id="Chicco-PrivacyCheck-element"> <input type="hidden" name="Chicco[PrivacyCheck]" value=""><input type="checkbox" name="Chicco[PrivacyCheck]" id="Chicco-PrivacyCheck" value="1"> </dd> <dt id="submit-label">&nbsp;</dt> <dd id="submit-element"> <input type="submit" name="Chicco[submit]" id="Chicco-submit" value="OK"> </dd> </dl> </fieldset> </dd> </dl> </form> How can I add a class="Test" to the <dd id="Chicco-element"> elemnt? In order to have it like that: <dd id="Chicco-element" class="Test"> I thought something like that but it don't work: $SubForm_Step->getDecorator('DdWrapper')->setOption('class', 'Test'); OR $SubForm_Step->getDecorator('DtDdWrapper')->setOption('class', 'Test'); How can I do it? And last question: How can I wrap that DD and DT element of a SubForm in another DL element? Like that: ( second line ) <dl class="zend_form"> <dl> <dt id="Chicco-label">&nbsp;</dt> <dd id="Chicco-element"> <fieldset id="fieldset-Chicco" class="Step"> <dl> .......

  • Require a default constructor in java?

    Is there any way to require that a class have a default (no parameter) constructor, aside from using a reflection check like the following? (the following would work, but it's hacky and reflection is slow) boolean valid = false; for(Constructor<?> c : TParse.class.getConstructors()) { if(c.getParameterTypes().length == 0) { valid = true; break; } } if(!valid) throw new MissingDefaultConstructorException(...);

  • SOAP WCF Webservice behaves differently when called locally or remotely

    - by Idriss
    I have a WCF SOAP 1.1 Webservice with the configuration specified below. A concurrent call to any method of this endpoint hangs until the other returns when called remotely (from another computer on the network). I cannot replicate this when these methods are called locally (with a client located on the same machine). I tried to increase the maxConcurrentCalls with no luck ... the service behavior seems to be different according to the client local/remote location. Any guess?
