This class was introduced in Qt 4.6.
Detailed Description
The QMatrix4x4 class in general is treated as a row-major matrix, in that the constructors and operator() functions take data in row-major format, as is familiar in C-style usage.
Internally the data is stored as column-major format, so as to be optimal for passing to OpenGL functions, which expect column-major data.
When using these functions be aware that they return data in column-major format:
- data()
- constData()
