<hr><a name="details"></a><h2>Detailed Description</h2>


<p> The TQBrush class defines the fill pattern of shapes drawn by a <a href="ntqpainter.html">TQPainter</a>.
<p> 


<p> A brush has a style and a color. One of the brush styles is a
custom pattern, which is defined by a <a href="ntqpixmap.html">TQPixmap</a>.
<p> The brush style defines the fill pattern. The default brush style
is <a href="ntqt.html#BrushStyle-enum">NoBrush</a> (depending on how you construct a brush). This style
tells the painter to not fill shapes. The standard style for
filling is <a href="ntqt.html#BrushStyle-enum">SolidPattern</a>.
<p> The brush color defines the color of the fill pattern. The <a href="ntqcolor.html">TQColor</a>
documentation lists the predefined colors.
<p> Use the <a href="ntqpen.html">TQPen</a> class for specifying line/outline styles.
<p> Example:
<pre>
        <a href="ntqpainter.html">TQPainter</a> painter;
        TQBrush   brush( yellow );           // yellow solid pattern
        painter.<a href="ntqpainter.html#begin">begin</a>( &amp;anyPaintDevice );   // paint something
        painter.<a href="ntqpainter.html#setBrush">setBrush</a>( brush );          // set the yellow brush
        painter.<a href="ntqpainter.html#setPen">setPen</a>( <a href="ntqt.html#PenStyle-enum">NoPen</a> );            // do not draw outline
        painter.<a href="ntqpainter.html#drawRect">drawRect</a>( 40,30, 200,100 ); // draw filled rectangle
        painter.<a href="ntqpainter.html#setBrush">setBrush</a>( <a href="ntqt.html#BrushStyle-enum">NoBrush</a> );        // do not fill
        painter.<a href="ntqpainter.html#setPen">setPen</a>( black );            // set black pen, 0 pixel width
        painter.<a href="ntqpainter.html#drawRect">drawRect</a>( 10,10, 30,20 );   // draw rectangle outline
        painter.<a href="ntqpainter.html#end">end</a>();                      // painting done
    </pre>
