Returns the actual size of the icon the engine provides for the requested size, mode and state.
The default implementation returns the given size.

Called by QIcon::addFile().
Adds a specialized pixmap from the file with the given fileName, size, mode and state. The default pixmap-based engine stores any supplied file names, and it loads the pixmaps on demand instead of using scaled pixmaps if the size of a pixmap matches the size of icon requested. Custom icon engines that implement scalable vector formats are free to ignores any extra files.

\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.

Returns true if the contents were read; otherwise returns false

Returns a pixmap for the given size, mode, state and scale.
The scale argument is typically equal to the \l {High DPI} {device pixel ratio} of the display.

References proxiedEngine(), and state.
Additional method to allow extending QIconEngine without adding new virtual methods (and without breaking binary compatibility). The actual action and format of data depends on id argument which is in fact a constant from IconEngineHook enum.
