Member Function Documentation

passedDragThreshold()

static bool score::DefaultComboImpl::passedDragThreshold ( QGraphicsSceneMouseEvent *  event )

inlinestaticnoexcept

Has the pointer travelled far enough since the press to mean "scrub" rather than "click"? Below the platform's drag threshold a wobble of a pixel or two is a click, and must not nudge the value.

stepAt()

static int score::DefaultComboImpl::stepAt ( const QGraphicsCombo &  self, QPointF  pos  )

inlinestaticnoexcept

+1 for the upper half of the stepper strip, -1 for the lower half, 0 if the point is not on the strip at all.

ungrabMouseEvent()

static void score::DefaultComboImpl::ungrabMouseEvent ( QGraphicsCombo &  self, QEvent *  event  )

inlinestatic

QEvent::UngrabMouse: the scene took the implicit grab away and there will be no release to end the drag on. See DefaultGraphicsSliderImpl for what goes wrong if the edit is left open.
