(Qt::WindowStates,Qt::WindowStates)</li></ul><a name="details" /><hr /><h2>Detailed Description</h2><p>The QMdiSubWindow class provides a subwindow class for <a href="qmdiarea.html">QMdiArea</a>.</p>
<p>QMdiSubWindow represents a top-level window in a <a href="qmdiarea.html">QMdiArea</a>, and consists of a title bar with
window decorations, an internal widget, and (depending on the
current style) a window frame and a size grip. QMdiSubWindow has
its own layout, which consists of the title bar and a center area
for the internal widget.</p>
<p class="centerAlign"><img alt="" src="images/qmdisubwindowlayout.png" /></p>
<p>The most common way to construct a QMdiSubWindow is to call
<a href="qmdiarea.html#addSubWindow">QMdiArea.addSubWindow</a>()
with the internal widget as the argument. You can also create a
subwindow yourself, and set an internal widget by calling <a href="qmdisubwindow.html#setWidget">setWidget</a>().</p>
<p>You use the same API when programming with subwindows as with
regular top-level windows (e.g., you can call functions such as
<a href="qwidget.html#show">show</a>(), <a href="qwidget.html#hide">hide</a>(), <a href="qwidget.html#showMaximized">showMaximized</a>(), and <a href="qwidget.html#windowTitle-prop">setWindowTitle</a>()).</p>
<a id="subwindow-handling" name="subwindow-handling" />
<h3>Subwindow Handling</h3>
<p>QMdiSubWindow also supports behavior specific to subwindows in
an MDI area.</p>
<p>By default, each QMdiSubWindow is visible inside the MDI area
viewport when moved around, but it is also possible to specify
transparent window movement and resizing behavior, where only the
outline of a subwindow is updated during these operations. The
<a href="qmdisubwindow.html#setOption">setOption</a>() function is
used to enable this behavior.</p>
<p>The <a href="qmdisubwindow.html#isShaded">isShaded</a>()
function detects whether the subwindow is currently shaded (i.e.,
the window is collapsed so that only the title bar is visible). To
enter shaded mode, call <a href="qmdisubwindow.html#showShaded">showShaded</a>(). QMdiSubWindow
emits the <a href="qmdisubwindow.html#windowStateChanged">windowStateChanged</a>()
signal whenever the window state has changed (e.g., when the window
becomes minimized, or is restored). It also emits <a href="qmdisubwindow.html#aboutToActivate">aboutToActivate</a>() before
it is activated.</p>
<p>In keyboard-interactive mode, the windows are moved and resized
with the keyboard. You can enter this mode through the system menu
of the window. The <a href="qmdisubwindow.html#keyboardSingleStep-prop">keyboardSingleStep</a>
and <a href="qmdisubwindow.html#keyboardPageStep-prop">keyboardPageStep</a>
properties control the distance the widget is moved or resized for
each keypress event. When shift is pressed down page step is used;
otherwise single step is used.</p>
<p>You can also change the active window with the keyboard. By
pressing the control and tab keys at the same time, the next (using
the current <a href="qmdiarea.html#WindowOrder-enum">WindowOrder</a>) subwindow will be
activated. By pressing control, shift, and tab, you will activate
the previous window. This is equivalent to calling <a href="qmdiarea.html#activateNextSubWindow">activateNextSubWindow()</a>
and <a href="qmdiarea.html#activatePreviousSubWindow">activatePreviousSubWindow()</a>.
Note that these shortcuts overrides global shortcuts, but not the
<a href="qmdiarea.html">QMdiArea</a>s shortcuts.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="SubWindowOption-enum" />QMdiSubWindow.SubWindowOption</h3><p>This enum describes options that customize the behavior of
<a href="qmdisubwindow.html">QMdiSubWindow</a>.</p>
<table class="valuelist">

<tr>
<td class="topAlign"><tt>QMdiSubWindow.RubberBandResize</tt></td>
<td class="topAlign"><tt>0x4</tt></td>
<td class="topAlign">If you enable this option, a rubber band
control is used to represent the subwindow's outline, and the user
resizes this instead of the subwindow itself. As a result, the
subwindow maintains its original position and size until the resize
operation has been completed, at which time it will receive a
single <a href="qresizeevent.html">QResizeEvent</a>. By default,
this option is disabled.</td>
</tr>
<tr>
<td class="topAlign"><tt>QMdiSubWindow.RubberBandMove</tt></td>
<td class="topAlign"><tt>0x8</tt></td>
<td class="topAlign">If you enable this option, a rubber band
control is used to represent the subwindow's outline, and the user
moves this instead of the subwindow itself. As a result, the
subwindow remains in its original position until the move operation
has completed, at which time a <a href="qmoveevent.html">QMoveEvent</a> is sent to the window. By default,
this option is disabled.</td>
</tr>
</table>
<p>The SubWindowOptions type is a typedef for <a href="qflags.html">QFlags</a><SubWindowOption>. It stores an OR
combination of SubWindowOption values.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QMdiSubWindow" />QMdiSubWindow.__init__ (<i>self</i>, <a href="qwidget.html">QWidget</a> <i>parent</i> = None, <a href="qt-windowflags.html">Qt.WindowFlags</a> <i>flags</i> = 0)</h3><p>The <i>parent</i> argument, if not None, causes <i>self</i> to be owned by Qt instead of PyQt.</p><p>Constructs a new <a href="qmdisubwindow.html">QMdiSubWindow</a>
widget. The <i>parent</i> and <i>flags</i> arguments are passed to
<a href="qwidget.html">QWidget</a>'s constructor.</p>
<p>Instead of using addSubWindow(), it is also simply possible to
use <a href="qwidget.html#setParent">setParent</a>() when you add
the subwindow to a <a href="qmdiarea.html">QMdiArea</a>.</p>
<p>Note that only <a href="qmdisubwindow.html">QMdiSubWindow</a>s
can be set as children of <a href="qmdiarea.html">QMdiArea</a>; you
cannot, for instance, write:</p>
<pre class="cpp">
QMdiArea mdiArea;
QTextEdit editor(&mdiArea); // invalid child widget
