\variable QIconEngine::ScaledPixmapArgument::size
The requested size of the pixmap.
\variable QIconEngine::ScaledPixmapArgument::mode
The requested mode of the pixmap.
\variable QIconEngine::ScaledPixmapArgument::state
The requested state of the pixmap.
\variable QIconEngine::ScaledPixmapArgument::scale
The requested scale of the pixmap.
\variable QIconEngine::ScaledPixmapArgument::pixmap
The pixmap that is the best match for the given \l size, \l mode, \l state, and \l scale. This is an output parameter that is set after calling \l virtual_hook().
Returns a key that identifies this icon engine.
