<p> This class is defined in the <b>TQt <a href="netscape-plugin.html#Netscape">Netscape</a> Extension</b>, which can be found in the <tt>qt/extensions</tt> directory. It is not included in the main TQt API.
<p>

The TQNPWidget class provides a <a href="tqwidget.html">TQWidget</a> that is a web browser plugin window.
<p> 
<p> Derive from TQNPWidget to create a widget that can be used as a
web browser plugin window, or create one and add child widgets.
Instances of TQNPWidget may only be created when
<a href="qnpinstance.html#newWindow">TQNPInstance::newWindow</a>() is called by the browser.
<p> A common way to develop a plugin widget is to develop it as a
stand-alone application window, then make it a <em>child</em> of a
plugin widget to use it as a browser plugin. The technique is:
<p> <pre>
class MyPluginWindow : public TQNPWidget
{
    <a href="tqwidget.html">TQWidget</a>* child;
public:
    MyPluginWindow()
    {
        // Some widget that is normally used as a top-level widget
        child = new MyIndependentlyDevelopedWidget();

        // Use the background color of the web page
        child-&gt;<a href="tqwidget.html#setBackgroundColor">setBackgroundColor</a>( <a href="tqwidget.html#backgroundColor">backgroundColor</a>() );

        // Fill the plugin widget
        child-&gt;<a href="tqwidget.html#setGeometry">setGeometry</a>( 0, 0, width(), height() );
    }

    void resizeEvent(TQResizeEvent*)
    {
        // Fill the plugin widget
        child-&gt;<a href="tqwidget.html#resize">resize</a>(<a href="tqwidget.html#size">size</a>());
    }
};
</pre>
 
<p> The default implementation is an empty window.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQNPWidget"></a>TQNPWidget::TQNPWidget ()
</h3>
Creates a TQNPWidget.

<h3 class=fn><a name="~TQNPWidget"></a>TQNPWidget::~TQNPWidget ()
</h3>
Destroys the window. This will be called by the plugin binding
code when the window is no longer required. The web browser will
delete windows when they leave the page. The bindings will change
the <a href="tqwidget.html#winId">TQWidget::winId</a>() of the window when the window is resized, but
this should not affect normal widget behavior.

<h3 class=fn>void <a name="enterInstance"></a>TQNPWidget::enterInstance ()<tt> [virtual]</tt>
</h3>
Called when the mouse enters the plugin window. Does nothing by
default.

<p>Example: <a href="grapher-nsplugin-example.html#x2753">grapher/grapher.cpp</a>.
<h3 class=fn><a href="qnpinstance.html">TQNPInstance</a>&nbsp;* <a name="instance"></a>TQNPWidget::instance ()
</h3>
Returns the instance for which this widget is the plugin window.

<h3 class=fn>void <a name="leaveInstance"></a>TQNPWidget::leaveInstance ()<tt> [virtual]</tt>
</h3>
Called when the mouse leaves the plugin window. Does nothing by
default.

<p>Example: <a href="grapher-nsplugin-example.html#x2754">grapher/grapher.cpp</a>.
