71 \class QGraphicsWidget -

72 \brief The QGraphicsWidget class is the base class for all widget -

73 items in a QGraphicsScene. -

74 \since 4.4 -

75 \ingroup graphicsview-api -

76 \inmodule QtWidgets -

77 -

78 QGraphicsWidget is an extended base item that provides extra functionality -

79 over QGraphicsItem. It is similar to QWidget in many ways: -

80 -

81 \list -

82 \li Provides a \l palette, a \l font and a \l style(). -

83 \li Has a defined geometry(). -

84 \li Supports layouts with setLayout() and layout(). -

85 \li Supports shortcuts and actions with grabShortcut() and insertAction() -

86 \endlist -

87 -

88 Unlike QGraphicsItem, QGraphicsWidget is not an abstract class; you can -

89 create instances of a QGraphicsWidget without having to subclass it. -

90 This approach is useful for widgets that only serve the purpose of -

91 organizing child widgets into a layout. -

92 -

93 QGraphicsWidget can be used as a base item for your own custom item if -

94 you require advanced input focus handling, e.g., tab focus and activation, or -

95 layouts. -

96 -

97 Since QGraphicsWidget resembles QWidget and has similar API, it is -

98 easier to port a widget from QWidget to QGraphicsWidget, instead of -

99 QGraphicsItem. -

100 -

101 \note QWidget-based widgets can be directly embedded into a -

102 QGraphicsScene using QGraphicsProxyWidget. -

103 -

104 Noticeable differences between QGraphicsWidget and QWidget are: -

105 -

106 \table -

107 \header \li QGraphicsWidget -

108 \li QWidget -

109 \row \li Coordinates and geometry are defined with qreals (doubles or -

110 floats, depending on the platform). -

111 \li QWidget uses integer geometry (QPoint, QRect). -

112 \row \li The widget is already visible by default; you do not have to -

113 call show() to display the widget. -

114 \li QWidget is hidden by default until you call show(). -

115 \row \li A subset of widget attributes are supported. -

116 \li All widget attributes are supported. -

117 \row \li A top-level item's style defaults to QGraphicsScene::style -

118 \li A top-level widget's style defaults to QApplication::style -

119 \row \li Graphics View provides a custom drag and drop framework, different -

120 from QWidget. -

121 \li Standard drag and drop framework. -

122 \row \li Widget items do not support modality. -

123 \li Full modality support. -

124 \endtable -

125 -

126 QGraphicsWidget supports a subset of Qt's widget attributes, -

127 (Qt::WidgetAttribute), as shown in the table below. Any attributes not -

128 listed in this table are unsupported, or otherwise unused. -

129 -

130 \table -

131 \header \li Widget Attribute \li Usage -

132 \row \li Qt::WA_SetLayoutDirection -

133 \li Set by setLayoutDirection(), cleared by -

134 unsetLayoutDirection(). You can test this attribute to -

135 check if the widget has been explicitly assigned a -

136 \l{QGraphicsWidget::layoutDirection()} -

137 {layoutDirection}. If the attribute is not set, the -

138 \l{QGraphicsWidget::layoutDirection()} -

139 {layoutDirection()} is inherited. -

140 \row \li Qt::WA_RightToLeft -

141 \li Toggled by setLayoutDirection(). Inherited from the -

142 parent/scene. If set, the widget's layout will order -

143 horizontally arranged widgets from right to left. -

144 \row \li Qt::WA_SetStyle -

145 \li Set and cleared by setStyle(). If this attribute is -

146 set, the widget has been explicitly assigned a style. -

147 If it is unset, the widget will use the scene's or the -

148 application's style. -

149 \row \li Qt::WA_Resized -

150 \li Set by setGeometry() and resize(). -

151 \row \li Qt::WA_SetPalette -

152 \li Set by setPalette(). -

153 \row \li Qt::WA_SetFont -

154 \li Set by setFont(). -

155 \row \li Qt::WA_WindowPropagation -

156 \li Enables propagation to window widgets. -

157 \endtable -

158 -

159 Although QGraphicsWidget inherits from both QObject and QGraphicsItem, -

160 you should use the functions provided by QGraphicsItem, \e not QObject, to -

161 manage the relationships between parent and child items. These functions -

162 control the stacking order of items as well as their ownership. -

163 -

164 \note The QObject::parent() should always return 0 for QGraphicsWidgets, -

165 but this policy is not strictly defined. -

286 \brief the size of the widget -

287 -

288 Calling resize() resizes the widget to a \a size bounded by minimumSize() -

290 height (e.g., its right and bottom edges); the widget's position and -

291 top-left corner remains unaffected. -

886 -

887 The widget's layout direction determines the order in which the layout -

892 side of this widget towards the right. Qt::RightToLeft does the opposite - -

893 the layout will place widgets starting from the right edge moving towards -

894 the left. -

895 -

896 Subwidgets inherit their layout direction from the parent. Top-level -

897 widget items inherit their layout direction from -

898 QGraphicsScene::layoutDirection. If you change a widget's layout direction -
