<p>This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.</p>
<p>Creates and returns a pixmap constructed by grabbing the contents of the given <i>window</i> restricted by <a href="../qtcore/qrect.html">QRect</a>(<i>x</i>, <i>y</i>, <i>width</i>, <i>height</i>).</p>
<p>The arguments (<i>x</i>, <i>y</i>) specify the offset in the window, whereas (<i>width</i>, <i>height</i>) specify the area to be copied. If <i>width</i> is negative, the function copies everything to the right border of the window. If <i>height</i> is negative, the function copies everything to the bottom of the window.</p>
<p>The window system identifier (<code>WId</code>) can be retrieved using the <a href="../qtwidgets/qwidget.html#winId">QWidget::winId</a>() function. The rationale for using a window identifier and not a <a href="../qtwidgets/qwidget.html">QWidget</a>, is to enable grabbing of windows that are not part of the application, window system frames, and so on.</p>
<p>The grabWindow() function grabs pixels from the screen, not from the window, i.e. if there is another window partially or entirely over the one you grab, you get pixels from the overlying window, too. The mouse cursor is generally not grabbed.</p>
<p>Note on X11 that if the given <i>window</i> doesn't have the same depth as the root window, and another window partially or entirely obscures the one you grab, you will <i>not</i> get pixels from the overlying window. The contents of the obscured areas in the pixmap will be undefined and uninitialized.</p>
<p>On Windows Vista and above grabbing a layered window, which is created by setting the <a href="../qtcore/qt.html#WidgetAttribute-enum">Qt::WA_TranslucentBackground</a> attribute, will not work. Instead grabbing the desktop widget should work.</p>
<p><b>Warning:</b> In general, grabbing an area outside the screen is not safe. This depends on the underlying window system.</p>
<p><b>Warning:</b> The function is deprecated in Qt 5.0 since there might be platform plugins in which window system identifiers (<code>WId</code>) are local to a screen. Use <a href="qscreen.html#grabWindow">QScreen::grabWindow</a>() instead.</p>
<p><b>See also </b><a href="qpixmap-obsolete.html#grabWidget">grabWidget</a>(), <a href="../qtwidgets/qtwidgets-desktop-screenshot-example.html">Screenshot Example</a>, and <a href="qscreen.html">QScreen</a>.</p>

<!-- $$$serialNumber[overload1]$$$serialNumber -->
<h3 class="fn" id="serialNumber"><a name="serialNumber"></a><span class="type">int</span> QPixmap::<span class="name">serialNumber</span>() const</h3>
<p>This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.</p>
<p>Returns a number that identifies the contents of this <a href="qpixmap.html">QPixmap</a> object. Distinct <a href="qpixmap.html">QPixmap</a> objects can only have the same serial number if they refer to the same contents (but they don't have to).</p>
<p>Use <a href="qpixmap.html#cacheKey">cacheKey</a>() instead.</p>
<p><b>Warning:</b> The serial number doesn't necessarily change when the pixmap is altered. This means that it may be dangerous to use it as a cache key. For caching pixmaps, we recommend using the <a href="qpixmapcache.html">QPixmapCache</a> class whenever possible.</p>
