<p>Virtual function that draws the contents of the frame on the given <i>painter</i>.</p>
<p>The <a href="qpainter.html">QPainter</a> is already open when you get it, and you must leave it open. Painter <a href="qpainter-obsolete.html#setWorldMatrix" class="obsolete">transformations</a> are switched off on entry. If you transform the painter, remember to take the frame into account and <a href="qpainter-qt3.html#resetXForm" class="compat">reset transformation</a> before returning.</p>
<p>This function is reimplemented by subclasses that draw something inside the frame. It should only draw inside <a href="q3frame.html#contentsRect-prop">contentsRect</a>(). The default function does nothing.</p>
<p><b>See also </b><a href="q3frame.html#contentsRect-prop">contentsRect</a>() and <a href="qpainter.html#setClipRect">QPainter::setClipRect</a>().</p>

<p>Draws the frame using the painter <i>p</i> and the current frame attributes and color group. The rectangle inside the frame is not affected.</p>
<p>This function is virtual, but in general you do not need to reimplement it. If you do, note that the <a href="qpainter.html">QPainter</a> is already open and must remain open.</p>
<p><b>See also </b><a href="qframe.html#frameRect-prop">frameRect</a>(), <a href="q3frame.html#contentsRect-prop">contentsRect</a>(), <a href="q3frame.html#drawContents">drawContents</a>(), <a href="qframe.html#frameStyle">frameStyle</a>(), and <a href="qwidget.html#palette-prop">setPalette</a>().</p>

<!-- $$$frameChanged[overload1]$$$frameChanged -->
<h3 class="fn"><a name="frameChanged"></a><span class="type">void</span> Q3Frame::<span class="name">frameChanged</span> ()<tt> [virtual protected]</tt></h3>
<p>Virtual function that is called when the frame style, line width or mid-line width changes.</p>
<p>This function can be reimplemented by subclasses that need to know when the frame attributes change.</p>
<!-- @@@frameChanged -->
<!-- $$$frameWidth[overload1]$$$frameWidth -->
<h3 class="fn"><a name="frameWidth"></a><span class="type">int</span> Q3Frame::<span class="name">frameWidth</span> () const</h3>

<p>Reimplemented from <a href="qwidget.html#resizeEvent">QWidget::resizeEvent</a>().</p>
<p>This just calls <a href="q3frame.html#frameChanged">frameChanged</a>(); it does not make use of the <i>event</i> itself.</p>
