To copy to clipboard, switch view to plain text mode 

I know that these locations all exist.

As for the initialization thing it's throwing out compile errors about an invalid conversion

datagen.cpp: In constructor `DataGen::DataGen()':
datagen.cpp:34: error: invalid conversion from `unsigned int' to `QTableWidget*
   '
datagen.cpp:34: error: invalid conversion from `unsigned int' to `QTableWidget*

Trying to solve that problem right now.

Edit: The QTableWidget pointer doesn't seem to want to let me initialize it's address to a random memory location...
