I think there should be a way to empty the vector without losing the memory. I
would have said clear() should do that, but clear() says it releases the memory.

Hello all,
could it be that QVector changed its behavior in Qt5? I just noticed that
resize(0) does deallocate memory, which is highly unexpected from my side. See
e.g. this old thread where it was said to use resize(0) to clear a vector
while keeping its capacity:
