wait

This question already has an answer here: How do I return the response from an asynchronous call? 36 answers I'm developing a javascript class (with jQuery) to create custom popup, but I can not figure out how to "pause" the script to wait for user response (click on the OK button or cancel) the class is like this: function Popup() { } Popup.Show = function(text) { var _response; /* code to draw the popup elements*/ $("#button-ok").on("click",function() { _response = "ok!" } return _response } if, for example, use it in an alert, the method always return "undefined", because it does not wait

I'm writing an activity in Android where the user modifies an SQL Database. The UI consists of an EditText where the user enters the name, and a Seekbar where the user enters how attractive the person is. Underneath there are a bunch of buttons: add, edit, view, delete. When the user clicks on the "Edit" button, an input dialog is displayed asking the user to input the record number. Once that is done, that record is loaded. The problem I was having was that the inputdialog would be displayed and while the user entering the record no, the rest of the edit method would carry on so that by the

I have an application where I am launching a new Activity, and need to have the result of the activity before proceeding. I realize that startActivityForResult is asynchronous / non-blocking, and that I can get the result of the activity in the onActivityResult callback. So I guess what I'm looking for is the best way to wait for the activity to return... Something like this perhaps? Or is there a better way? Activity Launcher Function: public String ActivityLauncher() { //Set up Intent startActivityForResult(intent, 1); while (mIsActivityDone == false) { Thread.Sleep(250); } //Continue with

I fork() into process X and Y, afterwards Y forks() again into itself and process Z multiple times. Now process Y is some kind of "listener" and I would like X to be the deleter. The Z processes perform the actual actions. Z processes are grandchildren of X. With a FIFO and some signaling, X has produced a list of all pids of the Z processes. The problem now is that I would like to delete Z process zombies with X (going through the list of pids). I've tried it with waitpid() , but of course that doesn't work (it only does for direct children). But I've read about the possibility of making an

How can I wait till the end of the jQuery function slideUp() before continuing the script? <script type="text/javascript"> $(document).ready(function() { $("div[class=item]").click(function() { var id = $(this).attr("id"); $("#content").slideUp(); switch(id) { // Applications case "rampro": $("#content").css("text-align", "left"); $("#content").load("inc/pages/rampro.html"); $("#content").slideDown(); break case "diskman": $("#content").css("text-align", "left"); $("#content").load("inc/pages/diskman.html"); break case "iconmap": $("#content").css("text-align", "left"); $("#content").load("inc

I've got a short question and I hope somebody can help me. Please look at the following code snippet: public void mouseEntered(MouseEvent e){ //wait 2 seconds. //if no other mouseEntered-event occurs, execute the following line //otherwise restart, counting the 2 seconds. foo(); } Can somebody help me with that problem? I want to realize a behavior like an ToolTip: you enter a region with your mouse. If your mouse stays in that position, do something. Start a Timer with a delay of 2 seconds in your mouseEntered() method that calls whatever it is you want to do. Set up a new handler (

Here is my code snippet. ExecutorService executor = Executors.newFixedThreadPool(ThreadPoolSize); while(conditionTrue) { ClassImplementingRunnable c = new ClassImplementingRunnable(); executor.submit(c); } Now after this is do executor.shutdown(); What i want to achieve here is that i want to wait for all the threads in the threadpool to have finished the execution and then i want to shutdown the executor. But i guess this is not what is happening here. The main thread seems to be executing shutdown and it just shuts down everything. Before when my threadpool size was 2, i did the following
