using a long-running thread, which calculates the time with a delay (sleep) between each update.using a timer which fires every 1/10th second triggering our time method.There are two options for implementing this To update the timer we need to run our time fetching and formatting code on a regular interval (every second). The correct time (at least it was when I took the screenshot) Updating the time using timers But you'll notice that the time doesn't update yet - we'll do that next. This means the time will be correct when the application starts - try closing it and re-running it to see the time update. If you run the application now, you should see the correct time displayed in the window. setProperty method is then called on that object. Next we use to select the first item in that list - in our case, there is only one item, our ApplicationWindow and that is what is returned. Our ApplicationWindow object is a root object because it appears at the top of the hierarchy. The code engine.rootObjects() gets all the root objects from the QML engine as a list. The time format string uses tokens such as %H to place specific parts of the time date in a specific format.įor example, if you enter the following in a Python shell you'll get the current GMT (UTC) time output.įrom PyQt5.QtQml import QQmlApplicationEngineĬurr_time = strftime("%H:%M:%S", localtime())Įngine.rootObjects().setProperty('currTime', curr_time) Two arguments - first a time format string, and second the time struct to use. Once you have a time struct you can pass this to the time.strftime() function to get a properly formatted string. Will give the time in your current local timezone. The Python standard library provides functions for handling time and date, including a number of options for getting the current time.įor example, the Python function time.gmtime() provides a struct containing the current GMT time, while time.localtime() Not the most useful of clocks! Next we'll add some Python code to get the current system time and update our clock display automatically. So far, our time display is just a fixed text string - it doesn't update, and unless you run it at the right time, it's going to be wrong. You will see the text has now moved to the bottom left.Īpplication window with text in the bottom left This is the bare minimum code required to load a QML file and display it using the QML application engine. Open up the main.py in your editor and add the following skeleton code.
