Qt is a cross-platform application and UI framework (qt.io).
Toradex is a partner of The Qt Company, the entity responsible for Qt development, productization and licensing under commercial and open-source licenses. This partnership is celebrated in the Partner Demo Image - Qt for Device Creation now available for download in the Toradex Easy Installer image format.
To get started sign-up for a free evaluation version of the Qt IDE.
Some of our Demos use Qt for its graphics capability. We recommend using the Qt framework for application development on our modules, on both Linux and WinCE.
Toradex optimized the WinCE display driver to improve Qt's performance on our modules. If you would like to improve graphic performances, take a look at Graphic Performance (Colibri).
Qt is a large framework available under a variety of licensing terms. This also depends on the version of Qt being used. Our partner the Qt Company can help you find the right license. Click here for details.
There are currently three possible ways to run the Qt framework on Toradex SoMs while using Embedded Linux:
Each has its own advantages and disadvantages. See a comparison between Torizon and the Reference Images on our Embedded Linux page. Learn more about the differences between the three offerings above on the webinar Kickstart your Qt Project on NXP i.MX 8 Series of Applications Processors with Toradex.
The Qt Company provides pre-built images of the Boot to Qt, a.k.a Boot2Qt software stack for several Toradex modules within Qt for Device Creation (formerly Enterprise Embedded). Such pre-built evaluation images are now available directly from the Toradex Easy Installer, try it out on Partner Demo Image - Qt for Device Creation and for more information refer to the Qt for Device Creation page.
The Qt for Device Creation toolset offers many benefits over the Qt under LGPL:
Note: Without the commercial version of Qt, the embedded Linux image and toolchain for deploying to a target device must be built manually.
Torizon, the easy-to-use industrial platform, makes it possible to easily run Qt on Toradex SoMs while benefiting from the Torizon ecosystem. More information on how to develop Qt apps on Torizon is provided in the Torizon Documentation.
Our Reference Multimedia Image for the Yocto Project has the Qt framework integrated. It does not provide an out-of-the-box experience as good as Boot2Qt or Torizon, but may be a good fit for your use case.
