state

问题 I would like to bind the boolean enabled property of an NSTextField to the state of an NSButton . I already tried adding a custom NSValueTransformer that transforms the state of the NSButton into NSNumber . However, in that scenario the text fields are disabled all the time for some reason. My second approach: To bad fails also since NSValueTransformer does not offer return primitives types such as BOOL . Example: The screenshot shows an example in which the text fields are disabled because

问题 I am getting unexpected results from both methods. I have my $state configed $stateProvider .state('status', { url: "/status/:payment", controller: 'QuestCtrl', templateUrl: "index.html" }); And on the Controller I have: angular.module('quest').controller('QuestCtrl',function($scope,$stateParams,$state){ console.log($stateParams.payment); // undefined console.log($state); // Object {params: Object, current: Object, $current: extend, transition: null} } I already used $stateParams in other

问题 I upgraded to UI Router 1.0.0, which has changed from .$on($stateChangeX to $transitions.onX( (see $transitions here). I need to resolve the user's profile and their access BEFORE navigation to the page (e.g. the user should never see the page they're attempting to transition to). Before, I was able to use a resolve directly in the state and pass thru things I need sequentially, as such: state('my-state', { ... resolve : { ProfileLoaded : ['$rootScope', function ($rootScope) { return

问题 I just read about maintaining state of my android app and stumbled upon onRetainNonConfigurationInstance. But while reading the documentation I noticed this sentence: This function is called purely as an optimization, and you must not rely on it being called. So I wonder: when does it really make sense to use this method. If I cannot rely on it being called, I need another mechanism to transfer state anyway (which in my case would be some serialization). So unless I experience any performance

问题 I'm trying to have AngularJS' UI-Router pick up on the defined states (i.e. "project") and if none match, default to the "root" state. The "root" state should check with a remote API (Firebase) and based on the result load the appropriate view. The example below doesn't accomplish either of those requirements: 1) "http://website.com/project" is matched to the "root" state, and not (the previously defined) "project" state. 2) "fbutil" is not defined in the "templateUrl" function, and cannot be

问题 I'm very new to React, just experimenting with it. I'd like to know what are some common patterns, or libraries o built-ins for handling communication among components. For example, I have am input component and a "list" component that updates from the server according to what is in the input controller. Think of an autocomplete box. Since components have presentation logic, What if the two can't be "besides"? They're in different parts of the page and hence two different controllers. Also,

问题 My button consists of only letters. Every time i press it, it has a black background. How do i disable the black background? I don´t want to change the color, i want to disable the pressed state. 回答1: You need to create selector under drawable folder and set color or image over there for different sates of the button. I have created one sample application for you and am pasting code snippet: Code for button_selector.xml that contains selector code for button which you will need to put under

问题 I'm having surprisingly difficult time figuring this out, essentially I'm trying to set state to initial state, so far I tried: // -- Initial state ------------------------------------------------------------ const INITIAL_STATE = { search: { listings: [] }, listings: [] } // -- Story structure for story editor ----------------------------------------- export default function(state = INITIAL_STATE, action) { switch(action.type) { case ACTIONS.RESET_STATE: return { ...state, INITIAL_STATE }

问题 One of the frustrations with the standard TreeView is that you can't show a partial selection to indicate that some of the children are selected. A partial selection in a complex tree allows the user to easily determine where the selections are, even if the tree is not completely expanded. A similar idea is used in manu backup programs to allow the user to select the files to be backed up. Does anyone know of a way to make the checks in a treeview checkbox gray? I want to gray the check of a

问题 I apologize if this is a duplication. What column standardization would you use for storing international country subdivision data? For example, if it was just US and Canada I believe all subdivisions have a 2-character abbreviation... which might lend to a Char(2) This cannot possibly be sustainable internationally lest we presume there are only 1296 (A-Z, 0-9) subdivisions. I've been unsuccessful locating an ISO list of these or even an indication of how to store them. That's fine, I don't
