    Thanks! I will take a look at the macdeployqt tool. In the mean time, I reset the app to use 4.7.3 so that I can continue my development work.

    Glad you made it! Please could you edit your title and add [Solved] in front of it? Also use @ instead of /[code/] to mark code in your topic. I changed it for you. (see the <> button on top of the editor.

    QVariant holds one value, so you can not stuff two things into it. You might try a QPair to group two separate things into one entity.

    [quote author="mlong" date="1311786901"]If loladiro's suggestion doesn't do what you need, then you'll need to draw each line segment on your own by iterating over the line segments and adjusting the pen accordingly for each one. [/quote] Already did it this way (also for another couple or reasons!) Thanks

    The QMdiArea is indeed not listed among the promoted widgets. I checked the reason for this with our developers here and QMdiArea is put in an exclude list since it is a container that it is problematic to promote. I see that you are investigating a way around this in this "thread":http://developer.qt.nokia.com/forums/viewthread/8334, and that sounds like a viable approach since QFrame is a container as well.

    Hi now i simply want to compile/run the main.cpp in the root folder and get: dlerror:/apps/X-Plane/Aircraft/General Aviation/Paa/alal/plugins/fmc/lin.xpl: undefined symbol: _ZN9FMSSystemC1Ev Compilation is ok without linking. So i cannot link for GPL reasons but what am i doing then? And why do i get the above error if i don't have to link? The lib is compiled and copied into the same folder as the plugin(main.cpp; x-plane plugin) above. Either the lib as the plugin are shared libs. Thanks again Michael

    Just a quick additional note on my last post - if you don't want to make your class asynchronous, too, you can wait for the signal right in your constructor, with something like this: @forever { if (/* Check for reply here /) { / Do reading here */ } else { // This ensures that your application will respond to events while waiting for the reply qApp->processEvents(); } } @ Although doing it in the constructor might be dangerous. Also, it will wait for an answer indefinitely... be careful :)
