It + demonstrates the use of the QNPInstance::writeReady() + and QNPInstance::write() functions. + + To build the example, you must first build the + <a href=nsplugin.html>Qt Netscape Plugin Extension</a> library. + Then type <tt>make</tt> in <tt>extensions/nsplugin/examples/grapher/</tt> + and copy the resulting <tt>grapher.so</tt> or <tt>npgrapher.dll</tt> + to the Plugins directory of your WWW browser. + + <EMBED ALIGN=LEFT WIDTH=49% HEIGHT=300 SRC=graph.g1n + graphstyle=pie fontfamily=times fontsize=18> + + The text file it accepts as input has a title line, then + a sequence of lines with a number, then a string. The + plugin displays a pie chart of the numbers, each segment + labelled by the associated string. The user can select + a bar chart view of the same data by selecting from the + menu that appears when they point at the plugin. + + The HTML tag used to embed the graph is: +<small> +<pre> + <EMBED + SRC=graph.g1n + ALIGN=LEFT + WIDTH=49% HEIGHT=300 + graphstyle=pie fontfamily=times + fontsize=18> +</pre> +</small> + Note that some HTML arguments (which we have capitalized here) + are interpreted by the browser, while others are used by the + plugin. + +<br clear> +With the simplicity and cross-platform nature of Qt-based plugins, +pages like <a href="http://www.netcraft.com/survey/">Netcraft's +Server Graphs</a> can be provided much more efficiently for both +the service provider and consumer.
