问题 How to create timer in WinApi (C++)? 回答1: Call the SetTimer function. This allows you to specify a callback function, or to have Windows post you a WM_TIMER message. 回答2: You cannot not know this if you write GUI code. Which makes it likely you want to use CreateTimerQueueTimer(). 回答3: SetTimer. A window handle is needed, and the timer will not be delivered if you aren't pumping messages. 回答4: A Good Example for CreateTimerQueueTimer : Here Another is HERE 回答5: call the setTimer() Function.

ScheduledExecutorService - Check if scheduled task has already been completed

问题 I have a server side application where clients can request to reload the configuration. If a client request to reload the configuration, this should not be done immediately, but with an delay of 1 minute. If another client also requests to reload the configuration in the same minute, this request should be ignored. My idea is to schedule a task with a ScheduledExecutorService like: ScheduledExecutorService service = Executors.newSingleThreadScheduledExecutor(); service.schedule(new

Updating JButton on a timer in a do-while loop

问题 I'm having some trouble getting a JButton to update repeatedly (used with a timer) in a do-while loop. I'm working on a simple game, played on a 10 * 10 grid of tile objects which correspond to a JButton arrayList with 100 buttons. This part of the program handles simple pathfinding (i.e. if I click on character, then an empty tile, the character will move through each tile on its way to the destination). There is a delay between each step so the user can see the character's progress. In the

Timer源码之TimerThread

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Timer只是管理着一个TimerTask任务队列（queue）而TimerTask的真正执行是由TimerThread来执行的，TimerThread继承了Thread，它的主要工作就是不断从优先级队列queue中取出任务检查是否到了可以执行的时间，如果可以执行就调用TimerTask的run方法。 非常值得注意的是任务队列（queue）中的TimerTask虽然实现了Runnable接口，但是在TimerThread中并没有启动新的线程来执行它，只有Thread的start方法才能启动新的线程。所以如果TimerTask中的run方法是死循环，那么可能Timer的任务队列中的TimerTask永远得不到执行的机会。还是先看一下TimerThread的代码吧。 import java.util.TimerTask; public class TimerThread extends Thread { boolean newTasksMayBeScheduled = true; /** * 任务队列的引用 */ private TaskQueue queue; TimerThread(TaskQueue queue) { this.queue = queue; } public void run() { try

问题 How do I get an image to change after a Swing timer is done? I know it plays the code in the actionPerformed class when it's done, but I could not get it to work. I have the image painted using the paint method if that changes anything :) public class Sprite extends JFrame implements ActionListener{ private Board board; private Timer timer; public Sprite() { timer = new Timer(1000, this); grow=false; } public Image grow() { if(grow) return image; else return other_image; } public void
