It features a <a href="qglwidget.html">QGLWidget</a> with a relatively expensive redrawing +operation, and rubber-band drawing in the overlay plane. Using the +overlay has the advantage that the rubber-band may be drawn and erased +without damaging the image in the main plane, so costly redraws are +avoided. +<p> See <tt>$QTDIR/examples/opengl/overlay</tt> for the source code. +<p> <p>See also <a href="opengl-examples.html">OpenGL Examples</a>. + +<!-- eof --> +<p><address><hr><div align=center> +<table width=100% cellspacing=0 border=0><tr> +<td>Copyright © 2007 +<a href="troll.html">Trolltech</a><td align=center><a href="trademarks.html">Trademarks</a> +<td align=right><div align=right>Qt 3.3.8</div> +</table></div></address></body> +</html> |
