Delphi thread as timer how to#

Head over and check out the full blog post by Marco about performing operations in the background of your apps.

Try them out and see which one works best for you. These same ideas apply across Delphi XE5, XE6, AppMethod, Android, IOS, Windows, and OSX. If you want to take advantage of multiple CPUs in your device you can do parallel processing with loops. Generally it is considered bad to use Application.ProcessMessages but I usually do it anyway. Some of the comments on the blog post talk about the Application.ProcessMessages function which you can use within loops to keep your app responsive even while performing work. There are also some threaded dialogs you can use for when you are performing work. WeвЂ™ve covered threads on here before and especially the anonymous thread class which comes as an extra addon with Delphi Firemonkey.

Finally he shows how to use a thread (which is a better way of completing work in the background).

Marco shows how you can use a timer to kind of achieve background operations and leave your UI responsive to the user. Performing the operations in the background or asynchronously solves this problem. Example usage: uses System.Diagnostics var StopWatch. While your app is doing work in the main thread of your application the user interface is blocked from responding to user input. Recent versions of Delphi ships with the TStopwatch record which is for time interval measurement. Marco Cantu has a blog post up where he demonstrates various ways for building non-blocking or asynchronous apps using Delphi XE6 Firemonkey.
