While the majority of the widgets are the same, the bit patterns used vary depending on the interface type being presented....

I have a C++ source file and a Python source file. I'd like the C++ source file to be able to use the contents of the Python source file as a big string literal. I could do something like this: char* python_code = " #include "script.py" " But that won't work because there need to be \'s at the end of each line. I could manually copy a...
