Here's what I'd do. 1. On mouse press, capture the position of the mouse and register that "scrubbing mode" is active. 2. When scrubbing mode is active, in your `mouseMoveEvent` compare the current position to the one stored on mouse press 3. The distance (e.g. Manhattan length <http://doc.qt.io/archives/qt-4.8/qpoint.html#manhattanLength>) is how much to scrub. 4. If the delta is positive, then you're scrubbing to the right. Negative means scrubbing to the left. 5. On mouse release, disable scrubbing mode.
This should help produce a smooth and predictable scrubbing behaviour.
