[solved] Qt Signal/Slots in one class but emitted from So the GUI class defines slots and signals, the signals are emitted in the implemented interface functions. The signals and slots are connected using: @"connect(this, SIGNAL(xyz), this SLOT(xyz));"@ I think the problem is that the intface functions that emit the signals are running in thread a but the GUI runs in thread b.
