Unix signal causing GUI to exit

[lni]

Hi,

I am struggling with GUI exit when a unix signal occurs, such as SIGSEGV or assert( false ). What I hope is to catch this signal and keep the application alive in order to give users a chance to save his data instead of losing everything in the middle of a job.

I am trying to write this signal handler, but it doesn't work as the signal occurs in the middle of the Qt event loop.

Please someone have a look at my codes and see if you can help.

Thanks.
