Use of operators in QVector3D

[Munkhtamir]

Hello,

I am a little confused that how to use operators from the desired class.

I want to use this operator in my class.

How to implement this operator in class?

Thank you,

QVector3D source;
QMatrix4x4 matrix;
QVector3D target = source * matrix;

You use it the way you'd use any expression operator that takes two arguments.
