What is OmniThreadLibrary?

OmniThreadLibrary is a powerful threading library for Delphi. OmniThreadLibrary's main "selling" points (besides the prices, of course ;) are power, simplicity, and openess. With just few lines of code, you can set up multiple threads, send messages between them, process Windows messages and more. OmniThreadLibrary doesn't limit you in any way - if it is not powerfull enough for you, you can ignore any part of its "smartness" and replace it with your own code.

How do I get OmniThreadLibrary?

Clone the latest version or follow the trunk.

Download the latest release.

Download an older release.

If you have Delphi XE8 or newer, you can install OmniThreadLibrary via GetIt.

If you have Delphi XE or newer, you can install Delphinus package manager and install OmniThreadLibrary there. (Delphinus-Support)

How do I use OmniThreadLibrary?

Download and install the sources. Compile and install the OmniThreadLibrary package. Read the tutorials. Examine the demos, which are part of the OmniThreadLibrary download.

At the moment, OTL supports Delphi 2007, 2009, 2010, XE, XE2, XE3, XE4, XE5, XE6, XE7, XE8, 10 Seattle, 10.1 Berlin, 10.2 Tokyo, 10.3 Rio, 10.4 Sydney, and 11 Alexandria on Win32 and Win64 platforms using the VCL framework.
