components

I have a custom class named MathLib.php and I need to use some login inside this class in all the controllers. Reading CakePHP documentations I found that components are the best way to do this. But Now, I have a problem, I would like to know where do I have to save the MathLib.php class (in what Folder do i have to put custom class), and How can I load it in a component. Thank you! If you wrote the custom class, you put it in app\libs for cake 1.x and in app\Lib for cake 2.x, if not it goes inside the app\vendors or app\Vendor. To load it in a component for cake 2.x you would add before your

Is there a BlackBerry library/component (open source or commercial) for integration in my own application that acts as QR code reader? I'd like to fully integrate it in my application. Or alternatively: is there a way to use the open source ZXing library in combination with the camera, ideally with live detection of the code? If you're targeting BlackBerry 6, RIM has now included the ZXing library as part of the OS: http://devblog.blackberry.com/2010/10/barcode-api/ For pre-6.0.0 applications, the webpage for the zxing project mentions JavaME and RIM-specific modules: http://code.google.com/p

I have a prop <graph :active-metrics="$data.active_metrics"></graph> In my child component I can access the value export default { template: '<div>{{activeMetrics}}</div>', props: ['active-metrics'], methods: { What I need to do is trigger a method in the child whenever there is a change. How can I achieve this? You can use v-bind to make the data from the parent flow down to the child. In your case it would look something like this: <graph v-bind:active-metrics="$data.active_metrics"></graph> export default { template: '<div>{{activeMetrics}}</div>', props: ['active-metrics'], watch: {

When unit-testing a component, the following question occured to me: There are a number of mouse-related event handlers. I see two possibilties to test these handlers: Simulate mouse events using Windows API calls. Use the protected hack to access protected event handlers and call them directly. I know that unit testing is normally restricted to the interface of a class (which also means that tests don't have to be changed when class internals change), but is this scenario worth an exception? How do you usually handle mouse events when unit-testing components? Personally, I think you need an

I am trying to create a Custom Flex Component using the Flex Component framework: http://www.adobe.com/livedocs/flex/3/html/help.html?content=ascomponents_advanced_3.html . All good components allow you to define their dimensions using percentage values using: MXML: TextInput width="100%" or Actionscript at runtime: textinp.percentWidth = 100; My question is how do you implement percentage width/height in the measure() method of your custom component? More specifically, these percentages are converted to pixels values at some stage, how is this done? The way Flex layouting works is by letting

I want to call a component inside a component with a variable, like this: Here's the code of the default.html-> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script> <div class="container"> <div class="row"> {% partial __SELF__ ~ "::category" category=__SELF__.category childscategory=__SELF__.childscategory%} <div class="col-xs-3"> <strong>DATA</strong> <ul class="list-group text-center"> {% partial __SELF__ ~ "::dates" files=__SELF__.files %} </ul> </div> <div class="col-xs-3"> <strong>Nome do Ficheiro</strong> <ul class="list-group text-center"> {% partial

Suppose the following code: TestComponent.propTypes = { text: React.PropTypes.string, myEnum: React.PropTypes.oneOf(['News', 'Photos']) }; I did the following in another file (that was using TestComponent): if (TestComponent.propTypes.text === React.PropTypes.string) {...} if (TestComponent.propTypes.myEnum === React.PropTypes.oneOf) {...} Well, to my satisfaction the first if worked. But the second if never returned true. I tried to modify it to the syntax below, but it did not help. if (TestComponent.propTypes.myEnum === React.PropTypes.oneOf(['News', 'Photos'])) {...} So, the question is:
