Ask HN: Learning Qt in a Week

Hi folks, I recently landed a job for creating Qt interfaces for OpenGL/C++. The job starts in a week.

However, I know nothing about Qt and its been almost four years since I programmed in C++.

Can you lovely folks please suggest learning material for Qt and C++?

I really don't want to get fired on the first day.

I have experience of creating user-interfaces for the web and have a WebGL background. They felt I could learn on the job and contribute.
