mouseEntered event disabled when mouseDown (NSEvents Mac)

I have created an NSButton class, and when rolling over my buttons it happily detects mouseEntered and mouseExited events. But as soon as the mouseDown event occurs, so long as the mouse it down, mouseEntered events are no longer called until the mouse button is lifted.

So, when the mouseDown event is called, mouseEntered or MouseExited events are no longer called, nor is mouseDown called when rolling over other buttons until I let go of the initial mouseDown.

So I would like to detect when my mouse enters while the mouse is down as well.

Solution

  • Turns out I just needed to add NSTrackingEnabledDuringMouseDrag to my NSTrackingAreaOptions. mouseEntered and mouseExited events now fire when dragging with mouse down.
