integrate new widgets into Qt

[flashburn]

I'm trying to design a flight instrument panel for a project I'm working on. I found a really nice set of components, https://sourceforge.net/projects/qfi/ and http://qwt.sourceforge.net/index.html, but I can't figure out how to add them to Qt. It would be better if I could integrate them into Qt Designer. I would really appreciate if someone could help me on how to install them into Qt and how to use new components after they are installed. Any help is appreciated.

How to add them to your project depends on the widget set itself and they probably both come with appropriate instructions. In general you need to link with the project library. Adding a widget set to Designer involves compiling the designer plugin (at least Qwt has one) with the same version of Qt your Creator is built against and deploying the plugin to Creator's QTDIR/plugins/designer directory.
