Using the Qt Installer Framework

The Qt Installer Framework (QIFW) is a collection of cross-platform tools and utilities for creating installers for the supported desktop Qt platforms, which include Linux, Windows, and macOS. It allows you to distribute your application across all supported desktop Qt platforms without having to rewrite the source code. The Qt Installer Framework tools create installers that include a collection of pages that help users through the installation, update, and removal processes. You provide the installable contents as well as information about it, such as the product name, the installer, and the legal agreement.

You may personalize the installers by adding widgets to the pre-defined pages or adding entire pages to give consumers more options. You may add operations to the installer by writing scripts. Depending on your use cases, you can give end customers an offline or online installation, or both. It works well on Windows, Linux, and Mac. We will...
