69 \class QGraphicsProxyWidget -
70 \brief The QGraphicsProxyWidget class provides a proxy layer for embedding -
71 a QWidget in a QGraphicsScene. -
72 \since 4.4 -
73 \ingroup graphicsview-api -
74 \inmodule QtWidgets -
75 -
76 QGraphicsProxyWidget embeds QWidget-based widgets, for example, a -
77 QPushButton, QFontComboBox, or even QFileDialog, into -
78 QGraphicsScene. It forwards events between the two objects and -
79 translates between QWidget's integer-based geometry and -
80 QGraphicsWidget's qreal-based geometry. QGraphicsProxyWidget -
81 supports all core features of QWidget, including tab focus, -
82 keyboard input, Drag & Drop, and popups. You can also embed -
83 complex widgets, e.g., widgets with subwidgets. -
84 -
85 Example: -
86 -
87 \snippet code/src_gui_graphicsview_qgraphicsproxywidget.cpp 0 -
88 -
89 QGraphicsProxyWidget takes care of automatically embedding popup children -
90 of embedded widgets through creating a child proxy for each popup. This -
91 means that when an embedded QComboBox shows its popup list, a new -
92 QGraphicsProxyWidget is created automatically, embedding the popup, and -
93 positioning it correctly. This only works if the popup is child of the -
94 embedded widget (for example QToolButton::setMenu() requires the QMenu instance -
95 to be child of the QToolButton). -
96 -
97 \section1 Embedding a Widget with QGraphicsProxyWidget -
98 -
99 There are two ways to embed a widget using QGraphicsProxyWidget. The most -
100 common way is to pass a widget pointer to QGraphicsScene::addWidget() -
101 together with any relevant \l Qt::WindowFlags. This function returns a -
102 pointer to a QGraphicsProxyWidget. You can then choose to reparent or -
103 position either the proxy, or the embedded widget itself. -
104 -
105 For example, in the code snippet below, we embed a group box into the proxy: -
106 -
107 \snippet code/src_gui_graphicsview_qgraphicsproxywidget.cpp 1 -
108 -
109 The image below is the output obtained with its contents margin and -
110 contents rect labeled. -
111 -
112 \image qgraphicsproxywidget-embed.png -
113 -
114 Alternatively, you can start by creating a new QGraphicsProxyWidget item, -
115 and then call setWidget() to embed a QWidget later. The widget() function -
116 returns a pointer to the embedded widget. QGraphicsProxyWidget shares -
117 ownership with QWidget, so if either of the two widgets are destroyed, the -
118 other widget will be automatically destroyed as well. -
119 -
120 \section1 Synchronizing Widget States -
121 -
122 QGraphicsProxyWidget keeps its state in sync with the embedded widget. For -
123 example, if the proxy is hidden or disabled, the embedded widget will be -
124 hidden or disabled as well, and vice versa. When the widget is embedded by -
125 calling addWidget(), QGraphicsProxyWidget copies the state from the widget -
126 into the proxy, and after that, the two will stay synchronized where -
127 possible. By default, when you embed a widget into a proxy, both the widget -
128 and the proxy will be visible because a QGraphicsWidget is visible when -
129 created (you do not have to call show()). If you explicitly hide the -
130 embedded widget, the proxy will also become invisible. -
131 -
132 Example: -
133 -
134 \snippet code/src_gui_graphicsview_qgraphicsproxywidget.cpp 2 -
135 -
136 QGraphicsProxyWidget maintains symmetry for the following states: -
137 -
138 \table -
139 \header \li QWidget state \li QGraphicsProxyWidget state \li Notes -
140 \row \li QWidget::enabled -
141 \li QGraphicsProxyWidget::enabled -
142 \li -
143 \row \li QWidget::visible -
144 \li QGraphicsProxyWidget::visible -
145 \li The explicit state is also symmetric. -
146 \row \li QWidget::geometry -
147 \li QGraphicsProxyWidget::geometry -
148 \li Geometry is only guaranteed to be symmetric while -
149 the embedded widget is visible. -
150 \row \li QWidget::layoutDirection -
151 \li QGraphicsProxyWidget::layoutDirection -
152 \li -
153 \row \li QWidget::style -
154 \li QGraphicsProxyWidget::style -
155 \li -
156 \row \li QWidget::palette -
157 \li QGraphicsProxyWidget::palette -
158 \li -
159 \row \li QWidget::font -
160 \li QGraphicsProxyWidget::font -
161 \li -
162 \row \li QWidget::cursor -
163 \li QGraphicsProxyWidget::cursor -
164 \li The embedded widget overrides the proxy widget -
165 cursor. The proxy cursor changes depending on -
166 which embedded subwidget is currently under the -
167 mouse. -
168 \row \li QWidget::sizeHint() -
169 \li QGraphicsProxyWidget::sizeHint() -
170 \li All size hint functionality from the embedded -
171 widget is forwarded by the proxy. -
172 \row \li QWidget::getContentsMargins() -
173 \li QGraphicsProxyWidget::getContentsMargins() -
174 \li Updated once by setWidget(). -
175 \row \li QWidget::windowTitle -
176 \li QGraphicsProxyWidget::windowTitle -
177 \li Updated once by setWidget(). -
178 \endtable -
179 -
180 \note QGraphicsScene keeps the embedded widget in a special state that -
181 prevents it from disturbing other widgets (both embedded and not embedded) -
182 while the widget is embedded. In this state, the widget may differ slightly -
183 in behavior from when it is not embedded. -
184 -
185 \warning This class is provided for convenience when bridging -
186 QWidgets and QGraphicsItems, it should not be used for -
187 high-performance scenarios. -

523 Embeds \a widget into this proxy widget. The embedded widget must reside -
524 exclusively either inside or outside of Graphics View. You cannot embed a -
525 widget as long as it is is visible elsewhere in the UI, at the same time. -
526 -
527 \a widget must be a top-level widget whose parent is 0. -
528 -
529 When the widget is embedded, its state (e.g., visible, enabled, geometry, -
530 size hints) is copied into the proxy widget. If the embedded widget is -
531 explicitly hidden or disabled, the proxy widget will become explicitly -
532 hidden or disabled after embedding is complete. The class documentation -
533 has a full overview over the shared state. -
534 -
535 QGraphicsProxyWidget's window flags determine whether the widget, after -
536 embedding, will be given window decorations or not. -
537 -
538 After this function returns, QGraphicsProxyWidget will keep its state -
539 synchronized with that of \a widget whenever possible. -
540 -
541 If a widget is already embedded by this proxy when this function is -
542 called, that widget will first be automatically unembedded. Passing 0 for -
543 the \a widget argument will only unembed the widget, and the ownership of -
544 the currently embedded widget will be passed on to the caller. -
545 Every child widget that are embedded will also be embedded and their proxy -
546 widget destroyed. -
547 -
548 Note that widgets with the Qt::WA_PaintOnScreen widget attribute -
549 set and widgets that wrap an external application or controller -
550 cannot be embedded. Examples are QGLWidget and QAxWidget. -
