event-handling

问题 I have searched the web a lot but couldn't find exactly what I want! suppose that I have a class derived from CWnd . In fact, it is the class COpenGLControl here in codeguru customized by me for my own purposes. the event handler for the WM_MOUSEMOVE button is written as follows: void COpenGLControl::OnMouseMove(UINT nFlags, CPoint point) { int diffX = (int)(point.x - m_fLastX); int diffY = (int)(point.y - m_fLastY); m_fLastX = (float)point.x; m_fLastY = (float)point.y; // Left mouse button

问题 I would like to filter a tree without type in the textfield, but when an event is triggered. I tried subclassing StoreFilterField like this: class MyStoreFilter<M extends ModelData> extends StoreFilterField<M>{ public MyStoreFilter() { super(); } public void startFilter(){ super.onFilter(); } @Override protected boolean doSelect(Store<M> store, M parent, M record, String property, String filter) { String name = record.get("name"); name = name.toLowerCase(); if (name.startsWith(filter

问题 I'm using .NET visual C# 2008 and in my webbrowser, I added click event handler to capture what html tag name I've clicked. But then I lost control to the webbrowser. When I start the application, in the webbrowser, I cannot enter texts into text field in the browser. It still accepts mouse clicks to the links though. I've found few people having this issue in forums but no solution is found. What am I doing wrong? Code : using System; using System.Collections.Generic; using System

问题 I'm dealing with a strange situation I want to debug in my Windows Phone 8.1 app, and I'm not sure in which moments OnNavigatedTo is called. Obviously, it gets called (and I've checked tracing it with the debugger) when you navigate to the view normally. My doubt arises in other point I want to check, let's call it "You wake up your application and the screen was shut off". My question is: When you turn on the screen, and you swype the screen protector away, is "OnNavigatedTo" function called

问题 I'm currently running this in a class that extends a JFrame. When I close the window, I don't see RAN EVENT HANDLER in the console. This is not the main window, and more than one instance of this window can exist at the same time. this.addWindowListener(new WindowAdapter() { @Override public void windowClosed(WindowEvent e) { System.out.println("RAN EVENT HANDLER"); } }); This method is inside a method called initialiseEventHandlers() which is called in the constructor, so I'm sure the code

问题 I am currently running into a problem with an eventlog monitor I created a while ago. My application subscribes to the EntryWritten events of the EventLog. I noticed that if multiple events occurs at the same time (within the same second), only one of them raises the event which triggers my eventhandler. _eventLog = new System.Diagnostics.EventLog(_logName); _eventLog.EntryWritten += new EntryWrittenEventHandler(eventlog_EntryWritten); _eventLog.EnableRaisingEvents = true; Is it possible to

问题 I have a ListView that is filled with a dynamic set of data each time the Activity is created. For simplicity's sake, lets say each ListView item is a employee's name. Under the hood, each employee has an employee_id number. This number is not visible anywhere in the interface. When I click on an employee's name in the ListView, I want to launch another activity, passing the corresponding employee's employee_id to that Activity. I understand how to implement the onClick handler for the

问题 I'm trying to use this API; however, I cannot get the events to fire. So this is using Network List 1.0 Type Library com. Here is my code: public class AvailibleWLan : INetworkListManagerEvents, INetworkEvents, INetworkConnectionEvents { public NETWORKLIST.INetworkListManager NewWorkList {get;set;} public List<WirelessNetwork> Connections { get; set; } public AvailibleWLan() { Connections = new List<WirelessNetwork>(); NewWorkList = new NETWORKLIST.NetworkListManager(); foreach (NETWORKLIST

问题 a can only be final here. Why? How can I reassign a in onClick() method without keeping it as private member? private void f(Button b, final int a){ b.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { int b = a*5; } }); } How can I return the 5 * a when it clicked? I mean, private void f(Button b, final int a){ b.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { int b = a*5; return b; // but return type is void } }); }

问题 I am trying to create a custom javascript EventManager class. I've adopted the format Grant Skinner uses in his easel.js framework for creating the class and need to stick with it. I'm really just lost at this point - I think that - at least in a conceptual sense - I have the right idea here and that it's mostly scope issues that evade me. I'm hoping someone here can help me take this to the point where addListener and dispatchEvent are functional. [code] (function(window) { var EventManager
