Member Function Documentation

◆ drawnRect()

QRectF Dataflow::PortItem::drawnRect ( ) const
inlinenoexcept

What paint() actually draws, as opposed to boundingRect(), which is deliberately larger. The ellipse is inset by one pixel at the small size and by three at the large one; see PortStyle in the .cpp.

◆ portCenter()

static constexpr QPointF Dataflow::PortItem::portCenter ( )
inlinestaticconstexprnoexcept

Center of the drawn port circle, in item coordinates. Cables, the drag line and magnetic snapping all anchor on this point.
