event-handling

问题 I have two questions: 1) Kernel-space process : When a process is executing in kernel mode, it does not receive any signals. Instead a process puts itself in a wait-queue when it expects to receive completion of any event. Such as completion of an I/O event . The process does not do anything at this stage. Once the event is triggered, ( the kernel sets a trap ? Correct if wrong ) and finally the process is waked up and resumes execution. Above is the case for expected events or (synchronous).

问题 I want the map of India and the list with text for the regions to listen to each other so that when the mouse pointer is hovering above a region then the corresponding region name gets underlined, and similarly if I hover over the name of the region to the left then the corresponding area on the map should be highlighted with the pink color. Can you help me? I can add code to listen for the hover event, but I'm not sure how to programmatically highlight the regions? I can listen for clicking

问题 Assuming I have the following repeater. <asp:Repeater ID="MyRepeater" runat="server" onitemdatabound="MyRepeater_ItemDataBound"> <FooterTemplate> </table> <asp:Button ID="btnPrevious" runat="server" Text="<" /> <asp:Label ID="lblCurrentPage" runat="server" Text="<%# PagingStatus() %>" /> <asp:Button ID="btnNext" runat="server" Text=">" /> </FooterTemplate> </asp:Repeater> How can I handle the click events from btnPrevious and btnNext ? I have tried the following: protected void MyRepeater

问题 I am experimenting with DOM event handlers, and I put in my Constructor's prototype a function that works on the DOM div element, which is a property created by the constructor in my object. It displays the object correctly, but the only thing that does not work is that it thinks that in my method, .keyCode , is a property of undefined and gives me an error message: TypeError: Cannot read property 'keyCode' of undefined (line 16 in function KeyBlock.move) This is my method, along with my

问题 I want to move my object on scene using keyboard inputs. To do this work, I create an empty game object and attach a .cs file to it. Code of this .cs file is below : void Update() { if (Input.GetKey ("up") ) { Debug.Log("up"); } else if (Input.GetKey ("down") ) { Debug.Log("down"); } } I press up key only once , it writes output string on condole 7 times. Shouldn't I use this function to handle keyboard input? 回答1: Please refer to http://docs.unity3d.com/ScriptReference/Input.GetKey.html

问题 I have a JFrame divided in two on one side I have a JPanel that has some JToggleButtons on it. in the other side I need to show the right JPanel when one of the JToggleButtons is clicked. Right now am using only one thread to do this. here is the JFrame public class AppFrame extends JFrame{ private JPanel content ; private JPanel menu; public AppFrame() { super("Title"); setLayout(BorderLayout()); //content is gonna hold JPanel1 or JPanel2 content = new JPanel(); menu = new menu(); this.add

问题 My problem: I need to detect what event (e.g. TextChanged) is currently being handled from within the handling Sub that's handling multiple objects/events. I cannot find examples online (though this may be a terminological issue). I already know how to detect the object but I do not know how to detect the event. To reproduce: In Visual Studio, in design mode, drag two text boxes onto a fresh form. Use the following as is: Code: Private Sub TextBox_CombinedEvents(sender As Object, e As

问题 I have an event queue to process. A thread adds events to the queue. I have created a runnable Task that in the run method does all which is necessary to process the event. I have declared an Executors.newCachedThreadPool(); and I execute each Task. public class EventHandler { private static final ExecutorService handlers = Executors.newCachedThreadPool(); public void handleNextEvent(AnEvent event){ handlers.execute(new Task(evt)); } public class Task implements Runnable{ @Override public

问题 I have a .NET 1.1. application which provides string resources through a bespoke translation system that looks a little like this: interface ITranslationProvider { string GetTranslation(string key); event LanguageChangedEvent LanguageChanged; } ie: language can change at runtime, and components need to respond by updating display strings. A single translation provider lasts the lifetime of the application, whereas Windows Forms components that consume translation services get created

问题 I have a windows store app that has a main form and several user controls. In each user control, I have an image, that, when tapped, should trigger a storyboard animation setup outside of the user control. The storyboard to fade the user control IN, works fine, but obviously I need the fade OUT animation to fire when the close button is clicked within the user control. Here's the code I added to the user control itself to fire when the close button is clicked. The problem is that it's firing
