transparentIconPixmap()

QPixmap transparentIconPixmap ( const QSize & logical, qreal scale )

inline

A fully transparent pixmap of logical size at device-pixel ratio scale, to be painted in logical coordinates.

A new QPixmap is uninitialised, and filling it through a painter with Qt::transparent is a no-op under SourceOver, so it is cleared directly.
