Sharing data between threads

[bbui210]

Hello everyone,

I'm using QT4.4.1 and have the following situation:

We have 'C' code with which we want to add a Graphical User Interface to, so I created the GUI using QT4 and built it as a static library. I then create a new thread in our multi-threaded 'C' application and execute the GUI. I was able to do with no problems at all, but now I want to be able to send data back and forth between the C-main function and the QT-main function (QT GUI Library).

I wasn't sure how to do this because the QApplication::exec() is necessary to start the GUI and has it's own event loop that processes different events.

Can anyone provide any help on this subject? Creating a separate thread in QT (QThreads) and running the C application is not an option because I will not have access to manipulate the C code, only the QT GUI library.


Regards,
BB
