QIconEngine::~QIconEngine () [virtual]

Destroys the icon engine.

QSize QIconEngine::actualSize ( const QSize & size, QIcon::Mode mode, QIcon::State state ) [virtual]

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

void QIconEngine::addFile ( const QString & fileName, const QSize & size, QIcon::Mode mode, QIcon::State state ) [virtual]

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.

void QIconEngine::addPixmap ( const QPixmap & pixmap, QIcon::Mode mode, QIcon::State state ) [virtual]

Called by QIcon::addPixmap(). Adds a specialized pixmap for the given mode and state. The default pixmap-based engine stores any supplied pixmaps, and it uses them instead of 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 pixmaps.

void QIconEngine::paint ( QPainter * painter, const QRect & rect, QIcon::Mode mode, QIcon::State state ) [pure virtual]

Uses the given painter to paint the icon with the required mode and state into the rectangle rect.

QPixmap QIconEngine::pixmap ( const QSize & size, QIcon::Mode mode, QIcon::State state ) [virtual]

Returns the icon as a pixmap with the required size, mode, and state. The default implementation creates a new pixmap and calls paint() to fill it.
