state

问题 I already had another question on this issue which was successfully resolved. But now, with a slightly different example, I'm stuck again. I have two states. When I switch from A to B, it resizes correctly, but when I switch from B back to A it happens without the smooth resize transition. What am I doing wrong? Here's my code: <fx:Script> <![CDATA[ protected function rollOverHandler(event:MouseEvent):void { this.currentState = "AB"; } protected function rollOutHandler(event:MouseEvent):void

问题 This question already has an answer here : Passing custom props to router component in react-router v4 (1 answer) Closed last year . This is parent component: class App extends Component { defaultState = { test: "hello" }; constructor(props) { super(props); this.state = this.defaultState } render() { return ( <Router> <Switch> <Route key="home" path="/" test={this.state.test} component={HomeScreen}/> </Switch> </Router> ); } } and this is the child component: class HomeScreen extends

问题 In my application, I want to keep track of multiple states. Thus I tried to encapsulate the whole state management logic within a class StateManager as follows: @SerialVersionUID(xxxxxxxL) class StateManager( inputStream: DStream[(String, String)], initialState: RDD[(String, String)] ) extends Serializable { lazy val state = inputStream.mapWithState(stateSpec).map(_.get) lazy val stateSpec = StateSpec .function(trackStateFunc _) .initialState(initialState) .timeout(Seconds(30)) def

问题 https://plnkr.co/edit/VV13ty8XaQ20tdqibmFy?p=preview Expected After login the dashboard state renders dashboard.html, and all components and ui-views should render: tickers , tags , social (named ui-view) and feed . Results After login the dashboard state renders dashboard.html however only the components tickers , tags and feed show up, but not the social (named-ui-view) I feel that my problem lies somewhere around where I transition from the login state to the dashboard state. Once you hit

问题 I manipulated a webpage DOM via some js libraries which altered the behaviour of onMouseup onMousedown and onMousemove , among other things which I can't be sure of. Using a DOM inspector I could see that some of these changes are set as properties of the main "document" object. So, what I am trying to figure out is a way to store, when the page is loaded, the initial state of the "document" object (or probably store the entire DOM?) so that later I will be able to restore it. My naive

问题 this is my first post! I am attempting to simply detect whether there is a keyboard attached to the PS/2 port on my machine. The idea is that the computer will boot up, although if it detects a USB device or PS/2 keyboard, it reboots into an administrator mode. I have handled the USB aspect, although I have had no luck in finding any documentation for the PS/2 port. Some posts have said it is not possible to detect a keyboard plugged into a PS/2 port after boot, although I simply wish to

问题 I work with embedded stuff, and I have some software module that manages hardware. This module has state, and state transitions are complicated: depending on events, the module could go from state A to state B or probably to C . But, when it exits some state, it should perform some actions with the hardware, in order to keep it in correct state too. For rather simple modules, I just have a couple of functions like this: enum state_e { MY_STATE__A, MY_STATE__B, }; static enum state_e _cur

问题 I am working on an application having UItableView . In the rows of the table i am able to put checkmarks.Now how to save the state of checkmarks so that even if user close the application the state should be shaved and in the next launch of application checkmark should be shown. i have followed the tutorials on NSUSerDefaults but Pulling my hairs where to put the codes of saving and retrieving.I have tried but every time errors are stuffing me and not able to fix. My Code: MY.h file **

问题 I populate my combo box and the user selects one of the options. Then they close everything. At a later date the user may open the window again and it would be tedious to ask them to retype and reselect the options again so I would like to 'load' them. I've tried to use pickle, but I get an error related to Qt apparently: self.WordCardsFieldSelector = QtGui.QComboBox() #Fails when trying to do this dump pickle.dump( self.WordCardsFieldSelector, open( "save.p", "wb" ) ) TypeError: the sip

问题 I am currently using the following to map my array to setState but nothing is getting set and no errors are being logged. If I explicitly write it out line by line, it works. Any thoughts or suggestions on how to go about this? Set State with Array: (Does not setSate) const myData = ['message', 'photo', 'isLoggedInhoto']; const newData = []; {[...Array(myData.length)].map((x, index) => newData.push(myData[index]) )} this.setState({ newData: localStorage.getItem(newData), }) Line by line (This
