This produces a static library to be linked with your plugin code. <li>Read the NSPlugin components in the <a href="annotated.html">class documentation</a>. <li>Examine the example plugins: <ul> <li><a href=trivial-trivial-cpp.html>Trivial example</a> <li><a href=qtimage-qtimage-cpp.html>Image example</a> <li><a href=grapher-grapher-cpp.html>Graphing example</a> </ul> <li>Do most of your development as a stand-alone Qt application - debugging Netscape Plugins is cumbersome. You may want to use <tt>signal(2)</tt> in your plugin to enable core-dumps if your browser disables them. <li>Note the platform-specific build steps below. <li>Read about the raw plugin interface <a href="http://developer.netscape.com/docs/manuals/communicator/plugin/index.htm"> in Netscape's handbook.</a> <li>If files viewed by a plugin are provided by an HTTP server (using a <tt>http://...</tt> URL) then the server must be configured to send the correct MIME type for the file, such as by editing the <tt>mime.types</tt> file of Apache. If the files are viewed via a <tt>file://...</tt> URL, then the browser will use the filename extension to decide the file type (and hence the plugin to load) - the user may need to set the filename extension in the Helpers or Applications section of their browser preferences.</ol>We are working on streamlining the build process for Qt-based Netscape Plugins. <h3>Building under X11</h3><ul> <li>The Makefiles in the examples are appropriate for UNIX/X11. <li>The user must install the resulting Shared Object in the Plugins directory of the browser.</ul><h3>Building under Windows</h3><ul> <li>Qt needs to be built as a static library when building Netscape plugins, we are looking into the problem of making it work with Qt as a dynamic library. <li>Plugins must be named <tt>np</tt><i>name</i><tt>.dll</tt>, or the browser will ignore them. <li>The link step must include: <ul> <li><tt>/def:</tt><i>name</i><tt>.def</tt> <li><tt>/dll</tt> <li>a compiled resource file defining the file/MIME types accepted by the plugin. </ul> <li>The user must install the resulting DLL in the Plugins directory of the browser.</ul><h2>Known Bugs</h2>The Qt-based LiveConnect Plugin binding code has a number ofminor bugs, but is sufficiently stable for most production applications.All of these have known solutions which we are working to implement.<ul> <li> MSIE 4.0 support is poor. <li> Crashes on X11 if window is closed via window manager. <li> Keyboard problems on Windows.</ul>*/?? 快捷鍵說明
