<h3 class=fn>const char * <a name="argv"></a>QNPInstance::argv ( int&nbsp;i ) const
</h3>
Returns the value of the <em>i</em>-th argument. See <a href="#argc">argc</a>().

<h3 class=fn>void * <a name="getJavaPeer"></a>QNPInstance::getJavaPeer () const
</h3>
Returns the Java object associated with the plug-in instance, an
object of the <a href="qnplugin.html#getJavaClass">plug-in's Java
    class</a>, or 0 if the plug-in does not have a Java class,
Java is disabled, or an error occurred.
<p> The return value is actually a <tt>jref</tt> we use <tt>void*</tt> so as to
avoid burdening plugins which do not require Java.
<p> <p>See also <a href="qnplugin.html#getJavaClass">QNPlugin::getJavaClass</a>() and <a href="qnplugin.html#getJavaEnv">QNPlugin::getJavaEnv</a>().

<h3 class=fn>void <a name="getURL"></a>QNPInstance::getURL ( const&nbsp;char&nbsp;*&nbsp;url, const&nbsp;char&nbsp;*&nbsp;window = 0 )
</h3>
Requests that the <em>url</em> be retrieved and sent to the named <em>window</em>. See Netscape's JavaScript documentation for an explanation
of window names.

<h3 class=fn>void <a name="getURLNotify"></a>QNPInstance::getURLNotify ( const&nbsp;char&nbsp;*&nbsp;url, const&nbsp;char&nbsp;*&nbsp;window = 0, void&nbsp;*&nbsp;data = 0 )
</h3>
Print the instance full-page. By default, this returns FALSE,
causing the browser to call the (embedded) <a href="#print">print</a>() function
instead. Requests that the given <em>url</em> be retrieved and sent to
the named <em>window</em>. See Netscape's JavaScript documentation for
an explanation of window names. Passes the arguments including <em>data</em> to NPN_GetURLNotify.

<h3 class=fn><a href="qnpinstance.html#InstanceMode-enum">InstanceMode</a> <a name="mode"></a>QNPInstance::mode () const
</h3>
Returns the mode of the plugin.

<h3 class=fn><a href="qnpstream.html">QNPStream</a>&nbsp;* <a name="newStream"></a>QNPInstance::newStream ( const&nbsp;char&nbsp;*&nbsp;mimetype, const&nbsp;char&nbsp;*&nbsp;window, bool&nbsp;as_file = FALSE )
</h3>
<p><b>This function is under development and is subject to change.</b>
<p> This function is <em>not tested</em>.
<p> Requests the creation of a new data stream <em>from</em> the plug-in.
The mime type and window are passed in <em>mimetype</em> and <em>window</em>.
<em>as_file</em> holds the <a href="#StreamMode-enum">AsFileOnly</a> flag. It is an interface to the
NPN_NewStream function of the Netscape Plugin API.

<h3 class=fn>bool <a name="newStreamCreated"></a>QNPInstance::newStreamCreated ( <a href="qnpstream.html">QNPStream</a>&nbsp;*, <a href="qnpinstance.html#StreamMode-enum">StreamMode</a>&nbsp;&amp;&nbsp;smode )<tt> [virtual]</tt>
</h3>

<p> This function is called when a new stream has been created. The
instance should return TRUE if it accepts the processing of the
stream. If the instance requires the stream as a file, it should
set <em>smode</em> to <a href="#StreamMode-enum">AsFileOnly</a>, in which case the data will be
delivered some time later to the <a href="#streamAsFile">streamAsFile</a>() function.
Otherwise, the data will be delivered in chunks to the <a href="#write">write</a>()
function which must consume at least as much data as was returned
by the most recent call to <a href="#writeReady">writeReady</a>().
<p> Note that the <a href="#StreamMode-enum">AsFileOnly</a> method is not supported by Netscape
2.0 and MSIE 3.0.

<h3 class=fn><a href="qnpwidget.html">QNPWidget</a>&nbsp;* <a name="newWindow"></a>QNPInstance::newWindow ()<tt> [virtual]</tt>
</h3>
Called at most once, at some time after the QNPInstance is
created. If the plugin requires a window, this function should
return a derived class of <a href="qnpwidget.html">QNPWidget</a> that provides the required
interface.

<p>Example: <a href="grapher-nsplugin-example.html#x2759">grapher/grapher.cpp</a>.
<h3 class=fn>void <a name="notifyURL"></a>QNPInstance::notifyURL ( const&nbsp;char&nbsp;*&nbsp;url, <a href="qnpinstance.html#Reason-enum">Reason</a>&nbsp;r, void&nbsp;*&nbsp;notifyData )<tt> [virtual]</tt>
</h3>
<p><b>This function is under development and is subject to change.</b>
<p> This function is <em>not tested</em>.
<p> Called whenever a <em>url</em> is notified after a call to
NPN_GetURLNotify with <em>notifyData</em>. The reason is given in <em>r</em>.
<p> It is an encapsulation of the NPP_URLNotify function of the
Netscape Plugin API.
<p> See also:
<a href="http://developer.netscape.com/docs/manuals/communicator/plugin/refpgur.htm#nppurlnotify">Netscape: NPP_URLNotify method</a>

<h3 class=fn>void <a name="postURL"></a>QNPInstance::postURL ( const&nbsp;char&nbsp;*&nbsp;url, const&nbsp;char&nbsp;*&nbsp;window, uint&nbsp;len, const&nbsp;char&nbsp;*&nbsp;buf, bool&nbsp;file )
</h3>
<p><b>This function is under development and is subject to change.</b>
<p> This function is <em>not tested</em>.
<p> It is an interface to the NPN_PostURL function of the Netscape
Plugin API.
<p> Passes <em>url</em>, <em>window</em>, <em>buf</em>, <em>len</em>, and <em>file</em> to
NPN_PostURL.

<h3 class=fn>void <a name="print"></a>QNPInstance::print ( <a href="qpainter.html">QPainter</a>&nbsp;* )<tt> [virtual]</tt>
</h3>
<p><b>This function is under development and is subject to change.</b>
<p> This function is <em>not tested</em>.
<p> Print the instance embedded in a page.
<p> It is an encapsulation of the NPP_Print function of the Netscape
Plugin API.

<h3 class=fn>bool <a name="printFullPage"></a>QNPInstance::printFullPage ()<tt> [virtual]</tt>
</h3>
<p><b>This function is under development and is subject to change.</b>
<p> This function is <em>not tested</em>.
<p> It is an encapsulation of the NPP_Print function of the Netscape
Plugin API.

<h3 class=fn>void <a name="status"></a>QNPInstance::status ( const&nbsp;char&nbsp;*&nbsp;msg )
</h3>
Sets the status message in the browser containing this instance to
<em>msg</em>.

<h3 class=fn>void <a name="streamAsFile"></a>QNPInstance::streamAsFile ( <a href="qnpstream.html">QNPStream</a>&nbsp;*, const&nbsp;char&nbsp;*&nbsp;fname )<tt> [virtual]</tt>
</h3>
Called when a stream is delivered as a single file called <em>fname</em>
rather than as chunks. This may be simpler for a plugin to deal
with, but precludes any incremental behavior.
<p> Note that the <a href="#StreamMode-enum">AsFileOnly</a> method is not supported by Netscape
2.0 and MSIE 3.0.
<p> <p>See also <a href="#newStreamCreated">newStreamCreated</a>() and <a href="#newStream">newStream</a>().

<h3 class=fn>void <a name="streamDestroyed"></a>QNPInstance::streamDestroyed ( <a href="qnpstream.html">QNPStream</a>&nbsp;* )<tt> [virtual]</tt>
</h3>
Called when a stream is destroyed. At this point, the stream may
be complete() and okay(). If it is not okay(), then an error has
occurred. If it is okay(), but not complete(), then the user has
cancelled the transmission: do not give an error message in this
case.

<h3 class=fn>const char * <a name="userAgent"></a>QNPInstance::userAgent () const
</h3>
Returns the user agent (browser name) containing this instance.

<h3 class=fn><a href="qnpwidget.html">QNPWidget</a>&nbsp;* <a name="widget"></a>QNPInstance::widget ()
</h3>
Returns the plugin window created by <a href="#newWindow">newWindow</a>(), if any.

<h3 class=fn>int <a name="write"></a>QNPInstance::write ( <a href="qnpstream.html">QNPStream</a>&nbsp;*, int&nbsp;offset, int&nbsp;len, void&nbsp;*&nbsp;buffer )<tt> [virtual]</tt>
</h3>

<p> Called when incoming data is available for processing by the
instance. The instance <em>must</em> consume at least the amount that it
returned in the most recent call to <a href="#writeReady">writeReady</a>(), but it may
consume up to the amount given by <em>len</em>. <em>buffer</em> is the data
available for consumption. The <em>offset</em> argument is merely an
informational value indicating the total amount of data that has
been consumed in prior calls.
<p> This function should return the amount of data actually consumed.

<p>Example: <a href="grapher-nsplugin-example.html#x2760">grapher/grapher.cpp</a>.
<h3 class=fn>int <a name="writeReady"></a>QNPInstance::writeReady ( <a href="qnpstream.html">QNPStream</a>&nbsp;* )<tt> [virtual]</tt>
</h3>
Returns the minimum amount of data the instance is willing to
receive from the given stream.
<p> The default returns a very large value.
