<hr><a name="details"></a><h2>Detailed Description</h2>
<p> This class is defined in the <b>TQt <a href="activentqt.html#ActiveTQt">ActiveTQt</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 TQAxScriptEngine class provides a wrapper around a script engine.
<p> Every instance of the TQAxScriptEngine class represents an interpreter
for script code in a particular scripting language. The class is usually
not used directly. The <a href="qaxscript.html">TQAxScript</a> and <a href="qaxscriptmanager.html">TQAxScriptManager</a> classes provide
convenient functions to handle and call script code.
<p> Direct access to the script engine is provided through
<a href="#queryInterface">queryInterface</a>().
<p> <b>Warning:</b> This class is not available with the bcc5.5 and MingW
compilers.
<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="State-enum"></a>TQAxScriptEngine::State</h3>
<p> The State enumeration defines the different states a script
engine can be in.
<ul>
<li><tt>TQAxScriptEngine::Uninitialized</tt> - The script has been created, but not yet initialized
<li><tt>TQAxScriptEngine::Initialized</tt> - The script has been initialized, but is not running
<li><tt>TQAxScriptEngine::Started</tt> - The script can execute code, but does not yet handle events
<li><tt>TQAxScriptEngine::Connected</tt> - The script can execute code and is connected so
that it can handle events
<li><tt>TQAxScriptEngine::Disconnected</tt> - The script is loaded, but is not connected to
event sources
<li><tt>TQAxScriptEngine::Closed</tt> - The script has been closed.
</ul>
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQAxScriptEngine"></a>TQAxScriptEngine::TQAxScriptEngine ( const <a href="ntqstring.html">TQString</a> & language, <a href="qaxscript.html">TQAxScript</a> * script )
</h3>
Constructs a TQAxScriptEngine object interpreting script code in <em>language</em>
provided by the code in <em>script</em>. This is usually done by the <a href="qaxscript.html">TQAxScript</a>
class when <a href="qaxscript.html#load">loading a script</a>.
<p> Instances of TQAxScriptEngine should always have both a language and a
script.
<h3 class=fn><a name="~TQAxScriptEngine"></a>TQAxScriptEngine::~TQAxScriptEngine ()
</h3>
Destroys the TQAxScriptEngine object, releasing all allocated
resources.
<h3 class=fn>void <a name="addItem"></a>TQAxScriptEngine::addItem ( const <a href="ntqstring.html">TQString</a> & name )
</h3>
Registers an item with the script engine. Script code can
refer to this item using <em>name</em>.
<h3 class=fn>bool <a name="hasIntrospection"></a>TQAxScriptEngine::hasIntrospection () const
</h3>
Returns TRUE if the script engine supports introspection;
otherwise returns FALSE.
<h3 class=fn>bool <a name="isValid"></a>TQAxScriptEngine::isValid () const
</h3>
<p> Returns TRUE if the script engine has been initialized
correctly; otherwise returns FALSE.
<h3 class=fn>long <a name="queryInterface"></a>TQAxScriptEngine::queryInterface ( const <a href="ntquuid.html">TQUuid</a> & uuid, void ** iface ) const
</h3>
Requests the interface <em>uuid</em> from the script engine object and
sets the value of <em>iface</em> to the provided interface, or to 0 if
the requested interface could not be provided.
<p> Returns the result of the QueryInterface implementation of the COM
object.
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="scriptLanguage"></a>TQAxScriptEngine::scriptLanguage () const
</h3>
Returns the scripting language, for example "VBScript",
or "JScript".
<h3 class=fn>void <a name="setState"></a>TQAxScriptEngine::setState ( <a href="qaxscriptengine.html#State-enum">State</a> st )
</h3>
Sets the state of the script engine to <em>st</em>.
Calling this function is usually not necessary.
<h3 class=fn><a href="qaxscriptengine.html#State-enum">State</a> <a name="state"></a>TQAxScriptEngine::state () const
</h3>
Returns the state of the script engine.
