545 \class QIcon-
546-
547 \brief The QIcon class provides scalable icons in different modes-
548 and states.-
549-
550 \ingroup painting-
551 \ingroup shared-
552 \inmodule QtGui-
553-
554 A QIcon can generate smaller, larger, active, and disabled pixmaps-
555 from the set of pixmaps it is given. Such pixmaps are used by Qt-
556 widgets to show an icon representing a particular action.-
557-
558 The simplest use of QIcon is to create one from a QPixmap file or-
559 resource, and then use it, allowing Qt to work out all the required-
560 icon styles and sizes. For example:-
561-
562 \snippet code/src_gui_image_qicon.cpp 0-
563-
564 To undo a QIcon, simply set a null icon in its place:-
565-
566 \snippet code/src_gui_image_qicon.cpp 1-
567-
568 Use the QImageReader::supportedImageFormats() and-
569 QImageWriter::supportedImageFormats() functions to retrieve a-
570 complete list of the supported file formats.-
571-
572 When you retrieve a pixmap using pixmap(QSize, Mode, State), and no-
573 pixmap for this given size, mode and state has been added with-
574 addFile() or addPixmap(), then QIcon will generate one on the-
575 fly. This pixmap generation happens in a QIconEngineV2. The default-
576 engine scales pixmaps down if required, but never up, and it uses-
577 the current style to calculate a disabled appearance. By using-
578 custom icon engines, you can customize every aspect of generated-
579 icons. With QIconEnginePluginV2 it is possible to register different-
580 icon engines for different file suffixes, making it possible for-
581 third parties to provide additional icon engines to those included-
582 with Qt.-
583-
584 \note Since Qt 4.2, an icon engine that supports SVG is included.-
585-
586 \section1 Making Classes that Use QIcon-
587-
588 If you write your own widgets that have an option to set a small-
589 pixmap, consider allowing a QIcon to be set for that pixmap. The-
590 Qt class QToolButton is an example of such a widget.-
591-
592 Provide a method to set a QIcon, and when you draw the icon, choose-
593 whichever pixmap is appropriate for the current state of your widget.-
594 For example:-
595 \snippet code/src_gui_image_qicon.cpp 2-
596-
597 You might also make use of the \c Active mode, perhaps making your-
598 widget \c Active when the mouse is over the widget (see \l-
599 QWidget::enterEvent()), while the mouse is pressed pending the-
600 release that will activate the function, or when it is the currently-
601 selected item. If the widget can be toggled, the "On" mode might be-
602 used to draw a different icon.-
603-
604 \image icon.png QIcon-
605-
606 \note QIcon needs a QGuiApplication instance before the icon is created.-
