<h3 class="fn"><a name="QColor-8"></a>QColor::QColor ( int <i>x</i>, int <i>y</i>, int <i>z</i>, <a href="qcolor.html#Spec-enum">Spec</a> <i>colorSpec</i> )</h3>
<p>Use one of the other <a href="qcolor.html">QColor</a> constructors, or one of the static convenience functions, instead.</p>
<h3 class="fn"><a name="getRgba"></a>void QColor::getRgba ( int * <i>r</i>, int * <i>g</i>, int * <i>b</i>, int * <i>a</i> ) const</h3>
<p>Use <a href="qcolor.html#getRgb">getRgb</a>() instead.</p>
<h3 class="fn"><a name="hsv"></a>void QColor::hsv ( int * <i>h</i>, int * <i>s</i>, int * <i>v</i> ) const</h3>
<p>Use <a href="qcolor.html#getHsv">getHsv</a>() instead.</p>
<p>See also <a href="qcolor.html#setHsv">setHsv</a>().</p>
<h3 class="fn"><a name="pixel"></a><a href="qtglobal.html#uint-typedef">uint</a> QColor::pixel ( int <i>screen</i> = -1 ) const</h3>
<p>Returns the pixel value used by the underlying window system to refer to a color.</p>
<p>Use <a href="qcolormap.html#pixel">QColormap::pixel</a>() instead.</p>
<p>For example, if you have code like</p>
<pre><font color="#404040"> QColor myColor;
uint pixel = myColor.pixel(screen);</font></pre>
<p>you can rewrite it as</p>
<pre> QColormap cmap = QColormap::instance(screen);
uint pixel = cmap.pixel(*this);</pre>
<h3 class="fn"><a name="rgb-2"></a>void QColor::rgb ( int * <i>r</i>, int * <i>g</i>, int * <i>b</i> ) const</h3>
<p>This is an overloaded member function, provided for convenience.</p>
<p>Use <a href="qcolor.html#getRgb">getRgb</a>() instead.</p>
<h3 class="fn"><a name="setRgba-2"></a>void QColor::setRgba ( int <i>r</i>, int <i>g</i>, int <i>b</i>, int <i>a</i> )</h3>
<p>This is an overloaded member function, provided for convenience.</p>
<p>Use <a href="qcolor.html#setRgb">setRgb</a>() instead.</p>
