<hr><a name="details"></a><h2>Detailed Description</h2>
<p> This class is defined in the <b>TQt <a href="activeqt.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 TQAxScript class provides a wrapper around script code.
<p> Every instance of the TQAxScript class represents a piece of
scripting code in a particular scripting language. The code is
loaded into the script engine using <a href="#load">load</a>(). Functions declared
in the code can be called using <a href="#call">call</a>().
<p> The script provides <a href="#scriptEngine">scriptEngine</a>() provides feedback to the
application through signals. The most important signal is the
<a href="#error">error</a>() signal. Direct access to the <a href="qaxscriptengine.html">TQAxScriptEngine</a> is provided
through the scriptEngine() function.
<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="FunctionFlags-enum"></a>TQAxScript::FunctionFlags</h3>
<p> This FunctionFlags enum describes formatting for function introspection.
<ul>
<li><tt>TQAxScript::FunctionNames</tt> - Only function names are returned.
<li><tt>TQAxScript::FunctionSignatures</tt> - Returns the functions with signatures.
</ul>
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQAxScript"></a>TQAxScript::TQAxScript ( const <a href="qstring.html">TQString</a> & name, <a href="qaxscriptmanager.html">TQAxScriptManager</a> * manager )
</h3>
Constructs a TQAxScript object called <em>name</em> and registers
it with the <a href="qaxscriptmanager.html">TQAxScriptManager</a> <em>manager</em>. This is usually done by the
TQAxScriptManager class when <a href="qaxscriptmanager.html#load">loading a
script</a>.
<p> A script should always have a name. A manager is necessary to allow
the script code to reference objects in the application. The <em>manager</em>
takes ownership of the object.
<h3 class=fn><a name="~TQAxScript"></a>TQAxScript::~TQAxScript ()
</h3>
Destroys the object, releasing all allocated resources.
<h3 class=fn><a href="qvariant.html">TQVariant</a> <a name="call"></a>TQAxScript::call ( const <a href="qstring.html">TQString</a> & function, const <a href="qvariant.html">TQVariant</a> & var1 = TQVariant ( ), const <a href="qvariant.html">TQVariant</a> & var2 = TQVariant ( ), const <a href="qvariant.html">TQVariant</a> & var3 = TQVariant ( ), const <a href="qvariant.html">TQVariant</a> & var4 = TQVariant ( ), const <a href="qvariant.html">TQVariant</a> & var5 = TQVariant ( ), const <a href="qvariant.html">TQVariant</a> & var6 = TQVariant ( ), const <a href="qvariant.html">TQVariant</a> & var7 = TQVariant ( ), const <a href="qvariant.html">TQVariant</a> & var8 = TQVariant ( ) )
</h3>
Calls <em>function</em>, passing the parameters <em>var1</em>, <em>var1</em>,
<em>var2</em>, <em>var3</em>, <em>var4</em>, <em>var5</em>, <em>var6</em>, <em>var7</em> and <em>var8</em>
as arguments and returns the value returned by the function, or an
invalid <a href="qvariant.html">TQVariant</a> if the function does not return a value or when
the function call failed.
<p> See <a href="qaxscriptmanager.html#call">TQAxScriptManager::call</a>() for more information about how to call
script functions.
<h3 class=fn><a href="qvariant.html">TQVariant</a> <a name="call-2"></a>TQAxScript::call ( const <a href="qstring.html">TQString</a> & function, <a href="qvaluelist.html">TQValueList</a><TQVariant> & arguments )
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Calls <em>function</em> passing <em>arguments</em> as parameters, and returns
the result. Returns when the script's execution has finished.
<p> See <a href="qaxscriptmanager.html#call">TQAxScriptManager::call</a>() for more information about how to call
script functions.
<h3 class=fn>void <a name="entered"></a>TQAxScript::entered ()<tt> [signal]</tt>
</h3>
<p> This signal is emitted when a script engine has started executing code.
<h3 class=fn>void <a name="error"></a>TQAxScript::error ( int code, const <a href="qstring.html">TQString</a> & description, int sourcePosition, const <a href="qstring.html">TQString</a> & sourceText )<tt> [signal]</tt>
</h3>
<p> This signal is emitted when an execution error occured while
running a script.
<p> <em>code</em>, <em>description</em>, <em>sourcePosition</em> and <em>sourceText</em>
contain information about the execution error.
<h3 class=fn>void <a name="finished"></a>TQAxScript::finished ()<tt> [signal]</tt>
</h3>
<p> This signal is emitted when a script engine has finished executing code.
<h3 class=fn>void <a name="finished-2"></a>TQAxScript::finished ( const <a href="qvariant.html">TQVariant</a> & result )<tt> [signal]</tt>
</h3> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> <em>result</em> contains the script's result. This will be an invalid
<a href="qvariant.html">TQVariant</a> if the script has no return value.
<h3 class=fn>void <a name="finished-3"></a>TQAxScript::finished ( int code, const <a href="qstring.html">TQString</a> & source, const <a href="qstring.html">TQString</a> & description, const <a href="qstring.html">TQString</a> & help )<tt> [signal]</tt>
</h3> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> <em>code</em>, <em>source</em>, <em>description</em> and <em>help</em> contain exception information
when the script terminated.
<h3 class=fn><a href="qstringlist.html">TQStringList</a> <a name="functions"></a>TQAxScript::functions ( <a href="qaxscript.html#FunctionFlags-enum">FunctionFlags</a> flags = FunctionNames ) const
</h3>
Returns a list of all the functions in this script if the respective
script engine supports introspection; otherwise returns an empty list.
The functions are either provided with full prototypes or only as
names, depending on the value of <em>flags</em>.
<p> <p>See also <a href="qaxscriptengine.html#hasIntrospection">TQAxScriptEngine::hasIntrospection</a>().
<h3 class=fn>bool <a name="load"></a>TQAxScript::load ( const <a href="qstring.html">TQString</a> & code, const <a href="qstring.html">TQString</a> & language = TQString::null )
</h3>
Loads the script source <em>code</em> written in language <em>language</em>
into the script engine. Returns TRUE if <em>code</em> was successfully
entered into the script engine; otherwise returns FALSE.
<p> If <em>language</em> is empty (the default) it will be determined
heuristically. If <em>code</em> contains the string <tt>End Sub</tt> it will
be interpreted as VBScript, otherwise as JScript. Additional
scripting languages can be registered using
TQAxScript::registerEngine().
<p> This function can only be called once for each TQAxScript object,
which is done automatically when using <a href="qaxscriptmanager.html#load">TQAxScriptManager::load</a>().
<h3 class=fn><a href="qstring.html">TQString</a> <a name="scriptCode"></a>TQAxScript::scriptCode () const
</h3>
Returns the script's code, or the null-string if no
code has been loaded yet.
<p> <p>See also <a href="#load">load</a>().
<h3 class=fn><a href="qaxscriptengine.html">TQAxScriptEngine</a> * <a name="scriptEngine"></a>TQAxScript::scriptEngine () const
</h3>
Returns a pointer to the script engine.
<p> You can use the object returned to connect signals to the
script functions, or to access the script engine directly.
<h3 class=fn><a href="qstring.html">TQString</a> <a name="scriptName"></a>TQAxScript::scriptName () const
</h3>
Returns the name of the script.
<h3 class=fn>void <a name="stateChanged"></a>TQAxScript::stateChanged ( int state )<tt> [signal]</tt>
</h3>
<p> This signal is emitted when a script engine changes state.
<em>state</em> can be any value in the TQAxScriptEngineState enumeration.
