|
|
<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 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.

<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>

<h3 class=fn><a name="TQAxScript"></a>TQAxScript::TQAxScript ( const <a href="ntqstring.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.

|
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="ntqvariant.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>
|
|
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.

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="ntqstring.html">TQString</a> & description, int sourcePosition, const <a href="ntqstring.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>
|
|

|
|
|
<h3 class=fn>void <a name="finished-2"></a>TQAxScript::finished ( const <a href="ntqvariant.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="ntqvariant.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="ntqstring.html">TQString</a> & source, const <a href="ntqstring.html">TQString</a> & description, const <a href="ntqstring.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="ntqstringlist.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="ntqstring.html">TQString</a> & code, const <a href="ntqstring.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="ntqstring.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.

|
<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="ntqstring.html">TQString</a> <a name="scriptName"></a>TQAxScript::scriptName () const
|
|
</h3>

</h3>
|

<p> This signal is emitted when a script engine changes state.
|
|
<em>state</em> can be any value in the TQAxScriptEngineState enumeration.
