It is not included in the main TQt API. +<p> + +The TQNPlugin class provides the main factory for plugin objects. +<p> +<p> This class is the heart of the plugin. One instance of this object +is created when the plugin is <em>first</em> needed, by calling +<a href="#create">TQNPlugin::create</a>(), which must be implemented in your plugin code +to return some derived class of TQNPlugin. The one TQNPlugin object +creates all <a href="tqnpinstance.html">TQNPInstance</a> instances for a web browser running in a +single process. +<p> Additionally, if TQt is linked to the plugin as a dynamic library, +only one instance of <a href="ntqapplication.html">TQApplication</a> will exist <em>across all plugins that have been made with TQt</em>. So, your plugin should tread lightly +on global settings. Do not, for example, use +<a href="ntqapplication.html#setFont">TQApplication::setFont</a>() - that will change the font in every +widget of every TQt-based plugin currently loaded! + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQNPlugin"></a>TQNPlugin::TQNPlugin ()<tt> [protected]</tt> +</h3> +Creates a TQNPlugin.
