Qt is a cross-platform application and UI framework (http://qt.digia.com/).
Toradex did several optimisation in the display driver to improve the performance of Qt on the toradex modules. If you like to improve the graphic performance, take a look here.
Download the Qt installer directly from Toradex. Qt 4.8.4 OpenGL SDK (module with OpenGL support e.g T20/T30) or Qt 4.8.4 SDK (for hardware with No OpenGL support e.g.Vybrid).
Download and install the Visual Studio Add-in 1.1.11 for Qt4 [here].
Download the installer qt-win-opensource-4.8.4-vs2008.exe and choose the installation directory as C:\Qt\4.8.4_x86 during installation steps [here].
Install the WinCE 7 SDK provided by Toradex [here].
Make sure you have installed VS2008 with SP1.
If you have installed later Toradex SDKs you have to patch the QT SDK installation. The following steps need to be done if your SDK is either called Toradex_CE600 for CE 6 or Toradex_CE700 for CE 7.
Qt setup Verification.
If everything is done correctly then you will see hardware accelerated rendering on the screen. Your setup is ready for building Qt application on the Toradex module.
The default deployment location of the program is the \Program Files folder on the toradex. If you face a "disk space full" message when deploying to this location you have three options:
If you like to reduce the size of Qt, have a look at http://www.formortals.com/build-qt-static-small-microsoft-intel-gcc-compiler.
You might face authentication related errors during building the example program. If this is the case close the project and open it again by going through the project folder (*.vcproj).
