<hr><a name="details"></a><h2>Detailed Description</h2>
The TQAssistantClient class provides a means of using TQt
Assistant as an application's help tool.
<p> Using TQt Assistant is simple: Create a TQAssistantClient instance,
then call <a href="#showPage">showPage</a>() as often as necessary to show your help
pages. When you call showPage(), TQt Assistant will be launched if
it isn't already running.
<p> The TQAssistantClient instance can open (<a href="#openAssistant">openAssistant</a>()) or close
(<a href="#closeAssistant">closeAssistant</a>()) TQt Assistant whenever required. If TQt Assistant
is open, <a href="#isOpen">isOpen</a>() returns TRUE.
<p> One TQAssistantClient instance interacts with one TQt Assistant
instance, so every time you call openAssistant(), showPage() or
closeAssistant() they are applied to the particular TQt Assistant
instance associated with the TQAssistantClient.
<p> When you call openAssistant() the <a href="#assistantOpened">assistantOpened</a>() signal is
emitted. Similarly when closeAssistant() is called,
<a href="#assistantClosed">assistantClosed</a>() is emitted. In either case, if an error occurs,
<a href="#error">error</a>() is emitted.
<p> This class is not included in the TQt library itself. To use it you
must link against <tt>libqassistantclient.a</tt> (Unix) or <tt>qassistantclient.lib</tt> (Windows), which is built into <tt>INSTALL/lib</tt>
if you built the TQt tools (<tt>INSTALL</tt> is the directory where TQt is
installed). If you use qmake, then you can simply add the following
line to your pro file:
<p> <pre>
LIBS += -lqassistantclient
</pre>
<p> See also "Adding Documentation to TQt Assistant" in the <a href="assistant.html">TQt Assistant manual</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQAssistantClient"></a>TQAssistantClient::TQAssistantClient ( const <a href="qstring.html">TQString</a> & path, <a href="qobject.html">TQObject</a> * parent = 0, const char * name = 0 )
</h3>
Constructs an assistant client object. The <em>path</em> specifies the
path to the TQt Assistant executable. If <em>path</em> is an empty
string the system path (<tt>%PATH%</tt> or <tt>$PATH</tt>) is used.
<p> The assistant client object is a child of <em>parent</em> and is called
<em>name</em>.
<h3 class=fn><a name="~TQAssistantClient"></a>TQAssistantClient::~TQAssistantClient ()
</h3>
Destroys the assistant client object and frees up all allocated
resources.
<h3 class=fn>void <a name="assistantClosed"></a>TQAssistantClient::assistantClosed ()<tt> [signal]</tt>
</h3>
<p> This signal is emitted when the connection to TQt Assistant is
closed. This happens when the user exits TQt Assistant, or when an
error in the server or client occurs, or if <a href="#closeAssistant">closeAssistant</a>() is
called.
<h3 class=fn>void <a name="assistantOpened"></a>TQAssistantClient::assistantOpened ()<tt> [signal]</tt>
</h3>
<p> This signal is emitted when TQt Assistant is open and the
client-server communication is set up.
<h3 class=fn>void <a name="closeAssistant"></a>TQAssistantClient::closeAssistant ()<tt> [virtual slot]</tt>
</h3>
Use this function to close TQt Assistant.
<p> <p>See also <a href="#assistantClosed">assistantClosed</a>().
<h3 class=fn>void <a name="error"></a>TQAssistantClient::error ( const <a href="qstring.html">TQString</a> & msg )<tt> [signal]</tt>
</h3>
<p> This signal is emitted if TQt Assistant cannot be started or if an
error occurs during the initialization of the connection between
TQt Assistant and the calling application. The <em>msg</em> provides an
explanation of the error.
<h3 class=fn>bool <a name="isOpen"></a>TQAssistantClient::isOpen () const
</h3><p>Returns TRUE if TQt Assistant is open; otherwise returns FALSE.
See the <a href="qassistantclient.html#open-prop">"open"</a> property for details.
<h3 class=fn>void <a name="openAssistant"></a>TQAssistantClient::openAssistant ()<tt> [virtual slot]</tt>
</h3>
This function opens TQt Assistant and sets up the client-server
communiction between the application and TQt Assistant. If it is
already open, this function does nothing. If an error occurs,
<a href="#error">error</a>() is emitted.
<p> <p>See also <a href="#assistantOpened">assistantOpened</a>().
<h3 class=fn>void <a name="setArguments"></a>TQAssistantClient::setArguments ( const <a href="qstringlist.html">TQStringList</a> & args )
</h3>
Sets the command line arguments used when TQt Assistant is
started to <em>args</em>.
<h3 class=fn>void <a name="showPage"></a>TQAssistantClient::showPage ( const <a href="qstring.html">TQString</a> & page )<tt> [virtual slot]</tt>
</h3>
Call this function to make TQt Assistant show a particular <em>page</em>.
The <em>page</em> is a filename (e.g. <tt>myhelpfile.html</tt>). See "Adding
Documentation to TQt Assistant" in the <a href="assistant.html">TQt
Assistant manual</a> for further information.
<p> If TQt Assistant hasn't been <a href="#openAssistant">opened</a>
yet, this function will do nothing. You can use <a href="#isOpen">isOpen</a>() to
determine whether TQt Assistant is up and running, or you can
connect to the asssistantOpened() signal.
<p> <p>See also <a href="#open-prop">open</a> and <a href="#assistantOpened">assistantOpened</a>().
<p>Example: <a href="helpsystem-example.html#x2686">helpsystem/mainwindow.cpp</a>.
<hr><h2>Property Documentation</h2>
<h3 class=fn>bool <a name="open-prop"></a>open</h3>
<p>This property holds whether TQt Assistant is open.
<p>
<p>Get this property's value with <a href="#isOpen">isOpen</a>().
