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 buy the Qt runtime from the closest Toradex office and sign-in for a free evaluation version of the Qt IDE.

Some of our Demos use Qt as graphics library and recommend to use the Qt framework for application development on our module, on both platforms, Linux and WinCE.

Toradex did also several optimization in the WinCE display driver to improve the performance of Qt on the Toradex modules. If you like to improve the graphic performance, take a look here.

Why Qt

• Easy GUI programming using Qt Designer (compared to MFC).
• Nice container classes
• Nice graphics scene framework
• Excellent documentation with useful examples
• Translation support
• Good technical support
• OpenGL ES2 support. Useful for embedded devices
• Cross-platform support (Same application runs on Windows, Mac, Linux, WinCE, iOS, Android)
• Shorter time to market
• Big Open Source community around Qt
• Use QtQuick (QML) for easy and good looking UIs
• QtQuick 2.2 by default uses OpenGL rendering for the processor with OpenGL support

What about licensing

Qt is a large framework with different licenses. Licenses also depend on which Qt version is used. Our partner the Qt Company can help you find the right license, click here for details.

Qt for Device Creation

The Qt Company provides pre-built images for Toradex Colibri VF50/VF61/iMX6/iMX7 and Apalis iMX6/iMX8 module in the Qt for Device Creation (formerly Enterprise Embedded) offerings. And now with the extensive partnership with The Qt Company, it is available the integration of Boot2Qt with Toradex Easy Installer for the target modules that support such image format.

Other modules can be offered to, for more information refer to the Qt for Device Creation page.

The Qt for Device Creation offers many benefits over the Qt under LGPL, namely

• Professional integrated tooling with Qt Creator Enterprise IDE
• Immediate prototyping with pre-built software stack, Boot to Qt
• Value-Added components: Qt Quick Enterprise Controls, Qt Virtual Keyboard, Qt Charts
• Qt Quick 2D Renderer for low-end modules such as Colibri VF50/VF61
• Shorter Time-to-Market
• Licensing terms more compatible to commercial project requirements
• Beautiful, High-Performing, Modern User-Interfaces
• Ultimate Performance for Embedded Devices
• Support is included with a valid maintenance agreement

Note: Without the commercial version of Qt, the embedded Linux image and toolchain for deploying to target must be built manually.
