As suggested in the comments to your question, the Timer component is a good solution to this. function Timer() { return Qt.createQmlObject(“import QtQuick 2.0; Timer {}”, root); } timer = new Timer(); timer.interval = 1000; timer.repeat = true; timer.triggered.connect(function () { print(“I’m triggered once every second”); }) timer.start(); The above would be how I’m currently … Read more
A solution to dismiss an alert automatically in Swift 3 and Swift 4 (Inspired by part of these answers: [1], [2], [3]): // the alert view let alert = UIAlertController(title: “”, message: “alert disappears after 5 seconds”, preferredStyle: .alert) self.present(alert, animated: true, completion: nil) // change to desired number of seconds (in this case 5 … Read more
The following will keep looking for someVariable until it is found. It checks every 0.25 seconds. function waitForElement(){ if(typeof someVariable !== “undefined”){ //variable exists, do what you want } else{ setTimeout(waitForElement, 250); } }
Using setTimeout() directly (which .delay() uses internally) is simpler here, since .remove() isn’t a queued function, overall it should look like this: $(‘body’).append(“<div class=”message success”>Upload successful!</div>”); setTimeout(function() { $(‘.message’).remove(); }, 2000); You can give it a try here. .delay() is for the animation (or whatever named) queue, to use it you’d have to do something … Read more
I found this extremely useful when developing my applications. As it gives you an alternative to simply re-queuing your messages. This can easily reduce the complexity of your code, and is one of many powerful hidden features in RabbitMQ. Steps First we need to set up two basic channels, one for the main queue, and … Read more
It won’t necessarily run right away, neither will explicitly setting the delay to 0. The reason is that setTimeout removes the function from the execution queue and it will only be invoked after JavaScript has finished with the current execution queue. console.log(1); setTimeout(function() {console.log(2)}); console.log(3); console.log(4); console.log(5); //console logs 1,3,4,5,2 for more details see http://javascriptweblog.wordpress.com/2010/06/28/understanding-javascript-timers/
There is such functionality in latest version of requests: https://requests.readthedocs.io/en/latest/api/?highlight=elapsed#requests.Response.elapsed For example: requests.get(“http://127.0.0.1”).elapsed.total_seconds()
I found three commands that helped me reduce the delay of live streams. The first command its very basic and straight forward, the second one it’s been combined with other options which might work differently on each environment and the last command it is a hacky version that I found in the documentation It was … Read more
Does pgsql have a waitfor statement like t-sql. Yes, pg_sleep: pg=> SELECT pg_sleep(10); pg_sleep ———- (1 row)
First, Google probably are blocking you because they don’t like it when you take too many of their resources. The best way to fix this is to slow it down, not delay randomly. Stick a 1 second wait after every request and you’ll probably stop having problems. That said: from random import randint from time … Read more
