In version 1.0, the canvas view is implemented as a customized QGraphicsScene/View. It has worked fairly well (surprisingly well, even) but Qt Quick has some irresistible advantages:
- OpenGL acceleration
- Declarative UI markup language! (QML)
- Much easier to port to mobile platforms
Since I had never used QML before, I decided to start by porting the playback dialog over first to get some practice. I chose this part because the dialog is fairly self contained and could therefore be rewritten without touching much else (yay, low coupling!)
