Installation to use QWT in QML project.

**pcw** · 14th May 2012, 18:22

I would like to use QWT PlotCurve in a QML based application (Qt Quick Project/Qt Quick Application). I have a windows 7 64-bit pc with mingw. I have looked at various threads about installing QWT/Qt but have not been successful in creating a application using QML and QWT PlotCurve. (have been able to get to the point where I see QWT Widgets in Qt Designer and am able to run QWT examples in Qt Creator).

I want to use the latest versions (e.g. Qt Creator 2.5.0, QWT 6.0.1, Qt 4.8.1).

Step 1 -
What componets do I need to download for QT (do I down load only qt-win-opensource-4.8.1-mingw.exe and qt-creator-win-opensource-2.5.0.exe or do I need the QtSDK)?

Step 2 -
What Qt components do I need to rebuild and what is the process.

Step 3 -
What is required for Qt configuration (e.g. setting environment variables, editing bat files, ect.

Step 4 -
What steps beyond the those in the INSTALL document are required for QWT?

Regards,

pcw

As far as I know there is nothing different how to embed Qwt widgets compared to embedding any other Qt widget in a QML based application.
The Qwt framework itself is pure C++ and doesn't offer a similar QML wrapper, like the Qt widgets.

For Qt 5.x this will change, but unfortunately the Qt development didn't make things easier with the decision to separate Qt Widgets and Qt Quick into incompatible worlds ...
