|
<p> The TQBrush class defines the fill pattern of shapes drawn by a <a href="tqpainter.html">TQPainter</a>.
|
||
|
13 years ago
|
<p>
|
||
|
|
|
||
|
|
|
||
|
|
<p> A brush has a style and a color. One of the brush styles is a
|
||
|
13 years ago
|
custom pattern, which is defined by a <a href="ntqpixmap.html">TQPixmap</a>.
|
||
|
13 years ago
|
<p> The brush style defines the fill pattern. The default brush style
|
||
|
13 years ago
|
is <a href="ntqt.html#BrushStyle-enum">NoBrush</a> (depending on how you construct a brush). This style
|
||
|
13 years ago
|
tells the painter to not fill shapes. The standard style for
|
||
|
13 years ago
|
filling is <a href="ntqt.html#BrushStyle-enum">SolidPattern</a>.
|
||
|
4 months ago
|
<p> The brush color defines the color of the fill pattern. The <a href="tqcolor.html">TQColor</a>
|
||
|
13 years ago
|
documentation lists the predefined colors.
|
||
|
13 years ago
|
<p> Use the <a href="ntqpen.html">TQPen</a> class for specifying line/outline styles.
