The regions of the display that have changed are updated -periodically, so you will see discrete snapshots of the framebuffer rather -than each individual drawing operation. For this reason drawing problems -such as flickering may not be apparent until the program is run using a real -framebuffer. -<p> The target refresh rate can be set via the <b>View|Refresh Rate</b> -menu item. This will cause <tt>qvfb</tt> to check for updated regions more -frequently. The rate is a target only. If little drawing is being -done, the framebuffer will not show any updates between drawing -events. If an application is displaying an animation the updates will -be frequent, then the application and <tt>qvfb</tt> will compete for -processor time. -<p> Mouse and keyboard events are passed to the TQt/Embedded master process via -named pipes. -<p> The virtual framebuffer is a development tool only. No security issues have -been considered in the virtual framebuffer design. It should be avoided -in a production environment; do not configure production libraries with <tt>-qvfb</tt>. -<p> -<!-- 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>TQt 3.3.8</div> -</table></div></address></body> -</html> |
