[OpenWalnut-Dev] Source of error

[Robin Ledig]

Hi,

I don't know if anyone ever tried to realy destroy a QWidget but in the 
config editor I noticed a source of error that could occur lots of times
and I found it all over OW.
If using especially layouts make sure to always use pointers not references.
If the parent gets destroyed Qt will try to free all children which can 
cause crashes if the destructor already released all none pointer QWidgets.

regards,
Robin
