41 \class QGraphicsEffect -

42 \brief The QGraphicsEffect class is the base class for all graphics -

43 effects. -

44 \since 4.6 -

45 \ingroup multimedia -

46 \ingroup graphicsview-api -

47 \inmodule QtWidgets -

48 -

49 Effects alter the appearance of elements by hooking into the rendering -

50 pipeline and operating between the source (e.g., a QGraphicsPixmapItem) -

51 and the destination device (e.g., QGraphicsView's viewport). Effects can be -

52 disabled by calling setEnabled(false). If effects are disabled, the source -

53 is rendered directly. -

54 -

55 To add a visual effect to a QGraphicsItem, for example, you can use one of -

56 the standard effects, or alternately, create your own effect by creating a -

57 subclass of QGraphicsEffect. The effect can then be installed on the item -

58 using QGraphicsItem::setGraphicsEffect(). -

59 -

60 Qt provides the following standard effects: -

61 -

62 \list -

63 \li QGraphicsBlurEffect - blurs the item by a given radius -

64 \li QGraphicsDropShadowEffect - renders a dropshadow behind the item -

65 \li QGraphicsColorizeEffect - renders the item in shades of any given color -

66 \li QGraphicsOpacityEffect - renders the item with an opacity -

67 \endlist -

68 -

69 \table -

70 \row -

71 \li{2,1} \image graphicseffect-plain.png -

72 \row -

73 \li \image graphicseffect-blur.png -

74 \li \image graphicseffect-colorize.png -

75 \row -

76 \li \image graphicseffect-opacity.png -

77 \li \image graphicseffect-drop-shadow.png -

78 \endtable -

79 -

80 \image graphicseffect-widget.png -

81 -

82 For more information on how to use each effect, refer to the specific -

83 effect's documentation. -

84 -

85 To create your own custom effect, create a subclass of QGraphicsEffect (or -

86 any other existing effects) and reimplement the virtual function draw(). -

87 This function is called whenever the effect needs to redraw. The draw() -

88 function takes the painter with which to draw as an argument. For more -

89 information, refer to the documenation for draw(). In the draw() function -

90 you can call sourcePixmap() to get a pixmap of the graphics effect source -

91 which you can then process. -

92 -

93 If your effect changes, use update() to request for a redraw. If your -

94 custom effect changes the bounding rectangle of the source, e.g., a radial -

95 glow effect may need to apply an extra margin, you can reimplement the -

96 virtual boundingRectFor() function, and call updateBoundingRect() -

97 to notify the framework whenever this rectangle changes. The virtual -

98 sourceChanged() function is called to notify the effects that -

99 the source has changed in some way - e.g., if the source is a -

100 QGraphicsRectItem and its rectangle parameters have changed. -

126 \class QGraphicsEffectSource -

127 \brief The QGraphicsEffectSource class represents the source on which a -

128 QGraphicsEffect is installed on. -

129 -

130 When a QGraphicsEffect is installed on a QGraphicsItem, for example, this -

131 class will act as a wrapper around QGraphicsItem. Then, calling update() is -

132 effectively the same as calling QGraphicsItem::update(). -

133 -

134 QGraphicsEffectSource also provides a pixmap() function which creates a -

135 pixmap with the source painted into it. -

1079 An opacity effect renders the source with an opacity. This effect is useful -

1080 for making the source semi-transparent, similar to a fade-in/fade-out -

1081 sequence. The opacity can be modified using the setOpacity() function. -

1082 -

1083 By default, the opacity is 0.7. -
