in a <a href="qgraphicsscene.html">QGraphicsScene</a>.</p>
<p>QGraphicsWidget is an extended base item that provides extra
functionality over <a href="qgraphicsitem.html">QGraphicsItem</a>.
It is similar to <a href="qwidget.html">QWidget</a> in many
ways:</p>
<ul>
<li>Provides a <a href="qgraphicswidget.html#palette-prop">palette</a>, a <a href="qgraphicswidget.html#font-prop">font</a> and a <a href="qgraphicswidget.html#style">style</a>().</li>
<li>Has a defined <a href="qgraphicslayoutitem.html#geometry">geometry</a>().</li>
<li>Supports layouts with <a href="qgraphicswidget.html#layout-prop">setLayout</a>() and <a href="qgraphicswidget.html#layout-prop">layout</a>().</li>
<li>Supports shortcuts and actions with <a href="qgraphicswidget.html#grabShortcut">grabShortcut</a>() and <a href="qgraphicswidget.html#insertAction">insertAction</a>()</li>
</ul>
<p>Unlike <a href="qgraphicsitem.html">QGraphicsItem</a>,
QGraphicsWidget is not an abstract class; you can create instances
of a QGraphicsWidget without having to subclass it. This approach
is useful for widgets that only serve the purpose of organizing
child widgets into a layout.</p>
<p>QGraphicsWidget can be used as a base item for your own custom
item if you require advanced input focus handling, e.g., tab focus
and activation, or layouts.</p>
<p>Since QGraphicsWidget resembles <a href="qwidget.html">QWidget</a> and has similar API, it is easier to
port a widget from <a href="qwidget.html">QWidget</a> to
QGraphicsWidget, instead of <a href="qgraphicsitem.html">QGraphicsItem</a>.</p>
<p><b>Note:</b> <a href="qwidget.html">QWidget</a>-based widgets
can be directly embedded into a <a href="qgraphicsscene.html">QGraphicsScene</a> using <a href="qgraphicsproxywidget.html">QGraphicsProxyWidget</a>.</p>
<p>Noticeable differences between QGraphicsWidget and <a href="qwidget.html">QWidget</a> are:</p>

<p>Although QGraphicsWidget inherits from both <a href="qobject.html">QObject</a> and <a href="qgraphicsitem.html">QGraphicsItem</a>, you should use the
functions provided by <a href="qgraphicsitem.html">QGraphicsItem</a>, <i>not</i> <a href="qobject.html">QObject</a>, to manage the relationships between
parent and child items. These functions control the stacking order
of items as well as their ownership.</p>
<p><b>Note:</b> The <a href="qobject.html#parent">QObject.parent</a>() should always return 0
for QGraphicsWidgets, but this policy is not strictly defined.</p>

instance. The optional <i>parent</i> argument is passed to <a href="qgraphicsitem.html">QGraphicsItem</a>'s constructor. The optional

whether the widget should be a window, a tool, a popup, etc).</p>
<h3 class="fn"><a name="actions" />list-of-QAction QGraphicsWidget.actions (<i>self</i>)</h3><p>Returns the (possibly empty) list of this widget's actions.</p>

actions.</p>
<p>All QGraphicsWidgets have a list of <a href="qaction.html">QAction</a>s, however they can be represented
graphically in many different ways. The default use of the <a href="qaction.html">QAction</a> list (as returned by <a href="qgraphicswidget.html#actions">actions</a>()) is to create a
context <a href="qmenu.html">QMenu</a>.</p>
<p>A <a href="qgraphicswidget.html">QGraphicsWidget</a> should only
have one of each action and adding an action it already has will
not cause the same action to be in the widget twice.</p>

<h3 class="fn"><a name="focusNextPrevChild" />bool QGraphicsWidget.focusNextPrevChild (<i>self</i>, bool <i>next</i>)</h3><p>Finds a new widget to give the keyboard focus to, as appropriate
for Tab and Shift+Tab, and returns true if it can find a new
widget; returns false otherwise. If <i>next</i> is true, this
function searches forward; if <i>next</i> is false, it searches
backward.</p>
<p>Sometimes, you will want to reimplement this function to provide
special focus handling for your widget and its subwidgets. For
example, a web browser might reimplement it to move its current
active link forward or backward, and call the base implementation
only when it reaches the last or first link on the page.</p>
<p>Child widgets call focusNextPrevChild() on their parent widgets,
but only the window that contains the child widgets decides where
to redirect focus. By reimplementing this function for an object,
you gain control of focus traversal for all child widgets.</p>

given <i>id</i> is enabled; otherwise it is disabled.</p>
<p>This function was introduced in Qt 4.5.</p>
<p><b>See also</b> <a href="qgraphicswidget.html#grabShortcut">grabShortcut</a>(), <a href="qgraphicswidget.html#releaseShortcut">releaseShortcut</a>(), and

<h3 class="fn"><a name="setShortcutEnabled" />QGraphicsWidget.setShortcutEnabled (<i>self</i>, int <i>id</i>, bool <i>enabled</i> = True)</h3><p>If <i>enabled</i> is true, the shortcut with the given <i>id</i>
is enabled; otherwise the shortcut is disabled.</p>
<p><b>Warning:</b> You should not normally need to use this
function since Qt's shortcut system enables/disables shortcuts
automatically as widgets become hidden/visible and gain or lose
focus. It is best to use <a href="qaction.html">QAction</a> or
<a href="qshortcut.html">QShortcut</a> to handle shortcuts, since
they are easier to use than this low-level function.</p>

<h3 class="fn"><a name="setStyle" />QGraphicsWidget.setStyle (<i>self</i>, <a href="qstyle.html">QStyle</a> <i>style</i>)</h3><p>Sets the widget's style to <i>style</i>. <a href="qgraphicswidget.html">QGraphicsWidget</a> does <i>not</i> take
ownership of <i>style</i>.</p>
<p>If no style is assigned, or <i>style</i> is 0, the widget will
use <a href="qgraphicsscene.html#style">QGraphicsScene.style</a>()
(if this has been set). Otherwise the widget will use <a href="qapplication.html#style">QApplication.style</a>().</p>
<p>This function sets the <a href="qt.html#WidgetAttribute-enum">Qt.WA_SetStyle</a> attribute if
<i>style</i> is not 0; otherwise it clears the attribute.</p>

so that keyboard focus moves from the <i>first</i> widget to the
<i>second</i> widget when the Tab key is pressed.</p>
<p>Note that since the tab order of the <i>second</i> widget is
changed, you should order a chain like this:</p>
<pre class="cpp">
setTabOrder(a<span class="operator">,</span> b); <span class="comment">// a to b</span>
setTabOrder(b<span class="operator">,</span> c); <span class="comment">// a to b to c</span>
setTabOrder(c<span class="operator">,</span> d); <span class="comment">// a to b to c to d</span>
</pre>
<p><i>not</i> like this:</p>
<pre class="cpp">
<span class="comment">// WRONG</span>
setTabOrder(c<span class="operator">,</span> d); <span class="comment">// c to d</span>
setTabOrder(a<span class="operator">,</span> b); <span class="comment">// a to b AND c to d</span>
setTabOrder(b<span class="operator">,</span> c); <span class="comment">// a to b to c, but not c to d</span>
</pre>
<p>If <i>first</i> is 0, this indicates that <i>second</i> should
be the first widget to receive input focus should the scene gain
Tab focus (i.e., the user hits Tab so that focus passes into the
scene). If <i>second</i> is 0, this indicates that <i>first</i>
should be the first widget to gain focus if the scene gained
BackTab focus.</p>
<p>By default, tab order is defined implicitly using widget
creation order.</p>

setVisible(true) has been called for the widget or one of its

<p>You can reimplement this event handler to detect when your
