7,406,247 | 0 | <p><code>Too much recursion</code> means that something is looping over and over again, possibly infinitely. The reason that's happening with your current code is because <code><a></code> is a parent of <code><img></code>, so any click event on <code><img></code> bubble up to the parent <code><a></code> (search for "event bubbling" in Google). So your code is basically saying "when someone clicks on <code><a></code>, trigger a click on <code><img></code> and then <code><a></code> (because of event bubbling)" -- which of course causes the code to run again.</p> <p>If the JavaScript plugin already has binded events to clicks on the image, I don't see why you need to bind a click event to the parent <code><a></code> that simply clicks on the image. What do you need to happen that isn't already happening when the user clicks on the <code><img></code> -- without including your jQuery code?</p> |

18,169,735 | 0 | <p>The input method framework is based upon the idea of an input connection. The framework instantiates one between the keyboard and the EditText. If you want to accept text from the keyboard you need to implement that side of the interface yourself, then get the framework to use your interface as the other half of the input session. This is really, really non-trivial and if you do it wrong specialized keyboards like Swype, Swiftkey, etc will not work correctly. I wouldn't suggest doing it without a very good reason. </p> <p>If you just want them to type into an existing edit text, focus that view instead. That way the input connection will be set to that view and everything will be done for you.</p> |

17,611,242 | 0 | <p>First of all, C++ is not designed to work like that. So it is not a surprise that this is happening.</p> <p>But, since you're using Visual Studio, you could take advantage of <a href="http://en.wikipedia.org/wiki/C%2B%2B/CX#Partial_classes" rel="nofollow">partial classes</a>. Unfortunately, it seems this characteristic is only related to C++/CX so maybe yo won't be able to use it.</p> <p>You will still need to declare a partial class in your namespace hierarchy, but I guess it could be empty.</p> <p>To be honest, I haven't used this feature and I don't know how far can it be bent in order to achieve what you want. But you could anyway give it a try.</p> <p>Remember that this is a Visual Studio extension, so your code won't be cross-platform.</p> <p>Hope this helps. Somehow.</p> |

972,282 | 0 | <p><strong>Regarding #9:</strong></p> <p>When you provide a context to your selector queries you limit the size of the tree being traversed to find the elements matching your selector, especially if you're using selectors that use tag names like: $('div > span').</p> <p>Performance depends on the type of selector and the number of elements in the context you're providing.</p> <p>Take a look at <a href="https://developer.mozilla.org/En/DOM/Document.getElementsByTagName" rel="nofollow noreferrer">getElementsByTagName</a> to better understand these issues.</p> <p>As for "which one is better" - this depends heavily on the size of the DOM being traversed and on a number of other elements, but in general, the first selector (the one with the context) should be faster.</p> <p><strong>Regarding #12:</strong></p> <p>In general, it is good practice to use event delegation when the number of child elements inside a parent element (cells inside a table, for example) is unknown and is expected to be quite large. This usually applies to cases where data is pulled from a server. The common scenarios are tree and grid structures.</p> <p><strong>Regarding #13:</strong></p> <p>I think the example provided in the document you're referring to does the job, but I'll try to elaborate a bit further. Classes are a common and standard way to attach additional information to HTML nodes. Lets take a Tab bar as an example: assuming you have a standard class "tab" which applies to every tab in your tab bar, you could add an additional class to one of the tabs to indicate that it is currently selected. Adding an additional class called "selected" would allow you to apply a different style to the selected tab and query the tab bar using jQuery for some additional logic (for example: check which tab is currently selected to perform an HTTP request and retrieve the content for this tab).</p> <p><strong>Regarding #14:</strong></p> <p>Classes are limited in the type and amount of data you can (or should) store in them. Data is a more flexible way to store large amounts of state data for HTML elements.</p> |

I also have a subclass of <code>UIView</code> called <code>MyView</code> that is a container view for 2 <code>UIViews</code> all in the same <code>UIViewController</code> and has some methods that control the interactions between the two views. </p> <p>My question is should I create delegates for <code>MyCollectionViewCell</code> and <code>MyView</code> so that the <code>ViewController</code> can handle all the logic or should I keep the classes self contained so that they control their own actions which can be called via the <code>ViewController</code> that they are both contained in?</p> |

26,009,819 | 0 | <p>Qt does not include a compiler. On Windows you're probably either compiling with mingw or Visual C++. Either way, the issue is that you're calling a function that expects a wide character string but you're trying to hand it an 8-bit character string.</p> <p>For compatibility reasons, <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ff381407%28v=vs.85%29.aspx" rel="nofollow">Win32 uses a different set of API functions if you have _UNICODE defined</a>. In your case, you do have _UNICODE defined. You can continue using the 8-bit std::string but simply change the method from <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms648045%28v=vs.85%29.aspx" rel="nofollow">LoadImage() to LoadImageA()</a>. Or if you don't mind changing your Bitmap class, you could switch from std::string to std::wstring to take advantage of Windows' Unicode features.</p> <p>But perhaps the larger question is why use Win32 to load bitmaps and std::string if you're using Qt? Qt's <a href="http://qt-project.org/doc/qt-5/QImage.html" rel="nofollow">QImage class</a> and <a href="http://qt-project.org/doc/qt-5/qstring.html" rel="nofollow">QString class</a> provide a full-featured, cross-platform strings and image loaders.

16,591,239 | 0 | Is this the true difference between using PhoneGap and simply opening a WebView in my application? <p>I was lately assigned to create a PhoneGap application for 4 different mobile platforms. After playing around with PhoneGap for a while , i decided it wasnt good to serve my purposes as there were no push-notification plugins for the WP7 and BB platforms.</p> <p>So i went native. I wrote native code for the different platforms that simply does 2 things:</p> <p><strong>1)</strong> <em>implement push notifications</em></p> <p><strong>2)</strong> <em>open an in-app webView</em></p> <p>My plan was that now with the webView i can open my "html-javascript web page" that i would use with the phonegap framework and it would be the same thing..</p> <p><strong>However...</strong> lately i found out that some javascript wont run in the BB (some older versions of OS) . So now i think i understand whats the difference between using PhoneGap and by simple opening a WebView.</p> <p><strong>IF</strong> i was using PhoneGap , the html-javascript code that i would write , would be <em>translated</em> through the framework to <em>native</em> code so it would run in the mobile. Now that i try to run javascript through the Web Browser , it simply wont run if the device doesnt support it.</p> <p>Am i right here? Is this the final big difference between these 2 things?</p> |
30,253,046 | 0 | <p>There are a few opportunities for speedup, but my first concern is <em>vector</em>. Where is it initialized? In the code posted, it gets n^2 entries and sorted n times! That seems unintentional. Should it be cleared? Should final be outside the loop?</p> <p>final=sorted(vector, key=lambda vector: vector[2],reverse = True)</p> <p>is functional, but has ugly scoping, better is:</p> <p>final=sorted(vector, key=lambda entry: entry[2], reverse=True)</p> <p>In general, to solve timing issues consider using a <a href="https://docs.python.org/2/library/profile.html" rel="nofollow">profiler</a>. </p> |

11,900,001 | 0 | Default parameter template vs variadic template : what is the last template parameter? <p>I'm a little confused because both a default parameter template and a variadic template parameter have to be the last parameter of a template. So what is the good official syntax for my function ?</p> <pre><code>template<typename T, class T2 = double, unsigned int... TDIM> myFunction(/* SOMETHING */) </code></pre> <p>or</p> <pre><code>template<typename T, unsigned int... TDIM, class T2 = double> myFunction(/* SOMETHING */) </code></pre> |
