|
||
|
|
<p> This class is defined in the <b>Qt <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 Qt API.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
The QNPWidget class provides a <a href="qwidget.html">QWidget</a> that is a web browser plugin window.
|
||
|
|
<p>
|
||
|
|
<p> Derive from QNPWidget to create a widget that can be used as a
|
||
|
|
web browser plugin window, or create one and add child widgets.
|
||
|
|
Instances of QNPWidget may only be created when
|
||
|
|
<a href="qnpinstance.html#newWindow">QNPInstance::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 QNPWidget
|
||
|
|
{
|
||
|
|
<a href="qwidget.html">QWidget</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-><a href="qwidget.html#setBackgroundColor">setBackgroundColor</a>( <a href="qwidget.html#backgroundColor">backgroundColor</a>() );
|
||
|
|
|
||
|
|
// Fill the plugin widget
|
||
|
|
child-><a href="qwidget.html#setGeometry">setGeometry</a>( 0, 0, width(), height() );
|
||
|
|
}
|
||
|
|
|
||
|
|
void resizeEvent(QResizeEvent*)
|
||
|
|
{
|
||
|
|
// Fill the plugin widget
|
||
|
|
child-><a href="qwidget.html#resize">resize</a>(<a href="qwidget.html#size">size</a>());
|
||
|
|
}
|
||
|
|
};
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> The default implementation is an empty window.
|
||
|
|
|
||
|
|
<hr><h2>Member Function Documentation</h2>
|
||
|
|
<h3 class=fn><a name="QNPWidget"></a>QNPWidget::QNPWidget ()
|
||
|
|
</h3>
|
||
|
|
Creates a QNPWidget.
|
||
|
|
|
||
|
|
<h3 class=fn><a name="~QNPWidget"></a>QNPWidget::~QNPWidget ()
|
||
|
|
</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="qwidget.html#winId">QWidget::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>QNPWidget::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">QNPInstance</a> * <a name="instance"></a>QNPWidget::instance ()
|
||
|
|
</h3>
|
||
|
|
Returns the instance for which this widget is the plugin window.
|
||
|
|
|
||
|
|
<h3 class=fn>void <a name="leaveInstance"></a>QNPWidget::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>.
