components

问题 How can I extend components like buttons to use x and y value as the center of the component, not the top left? 回答1: It's pretty easy in Flex 4 :). They have a transformAround method in the UIComponent, that allows you to transform the position/scale/rotation of a component around any arbitrary pivot. So you could do this: override public function set x(value:Number):void { var pivot:Vector3D = new Vector3D(this.width/2, this.height/2, 0); var translation:Vector3D = new Vector3D(value, this.y

问题 I am trying to make a custom component that call itself. i keep getting an error Unknown custom element: <TestRec> - did you register the component correctly? For recursive components, make sure to provide the "name" option. I have included a name option as you can see below but this doesn't solve the problem. Any idea what it could be? <template> <div> <h4>I am a component that can call itself below</h4> <v-select :items="['TestRec', 'normal']" v-model="comp"></v-select> <hr /> <component

问题 How do i load my React toolbar component conditionally on state change? constructor(props) { super(props); this.state = { currentpagenum: 0, }; } render(){ return( <View> {this.state.currentpagenum!==0 ? this.getToolbar(): null;} </View> ); } getToolbar(){ return( <ToolbarAndroid /> ); } 回答1: Looks like you got a typo error you added ; after null this is unneeded also you can get rid of the getToolbar function Instead try: constructor(props) { super(props); this.state = { currentpagenum: 0, }

问题 I wrote an Ember component that represents a styled input field that can handle file uploads. In order to achieve this I used a <div> and an <input> . The <input> has visibility: hidden and once the click event on the <div> is fired I fire the click event on the invisible <input> in the action handling of the Ember component. My problem is that after choosing files the action never reaches my Ember component. add-document-input.hbs <div {{action "add"}} class="floating-button"> <span>+</span>

问题 So I am working on a project that will allow a user to modify a template. The base template will be made up for components and the user will be able to add or remove components. I found a few things online - such as grapeJS but it is far to intense for this simple application. Looking for some advice on a way to go about this, or any resources that will help. Here is a basic example. Basic template will consist of these components Header Text Post Single Image Footer The list of components a

问题 Need help figuring out how to include images in a reusable component that is referenced in another app. For example, I have an Angular App, let's call it UI-Common, that contains common components and another Angular App, let's call it Command-Center, that will use those common components. In UI-Common, there is a component called my-control.component that is defined as follows: [my-control.component.html] <div> <img src="assets/images/myImage.png"/> <div class"username" *ngIf="user"> <p>

问题 I have 2 MEF components. Let it be component A and component B. What I need is to be able to access a class from component B in component A without referencing to it. Then I would like to instantiate object of the class manually. Currently I see MEF allows instantiating an object automatically using [Import]. It uses interface which requires to be referenced to. Can I use data types from another assemblies without referencing to it? Is there such mechanism supported by MEF? 回答1: There are a

问题 When I refresh my web-app, I want it to request the potential signed in user's data before instantiating any components or routes. If the user's data was found, I want to inject it into a service, which all my other sub components depend on. Scenario: Say I have 3 components, App (ROOT), Home & About. If I place this code in my About component, I expect it to wait 20seconds before it instantiate, instead, the component gets instantiated instantly, only when I move away from this component, it

问题 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.
