|
||
|
|
<p> This class is defined in the <b>Qt <a href="activeqt.html#ActiveQt">ActiveQt</a> Extension</b>, which can be found in the <tt>qt/extensions</tt> directory. It is not included in the main Qt API.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
The QAxScriptEngine class provides a wrapper around a script engine.
|
||
|
|
|
||
|
|
|
||
|
|
<p> Every instance of the QAxScriptEngine class represents an interpreter
|
||
|
|
for script code in a particular scripting language. The class is usually
|
||
|
|
not used directly. The <a href="qaxscript.html">QAxScript</a> and <a href="qaxscriptmanager.html">QAxScriptManager</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.

|
<h3 class=fn><a name="State-enum"></a>QAxScriptEngine::State</h3>
|
||
|
|
|
||
|
|
<p> The State enumeration defines the different states a script
|
||
|
|
engine can be in.
|
||
|
|
<ul>
|
||
|
|
<li><tt>QAxScriptEngine::Uninitialized</tt> - The script has been created, but not yet initialized
|
||
|
|
<li><tt>QAxScriptEngine::Initialized</tt> - The script has been initialized, but is not running
|
||
|
|
<li><tt>QAxScriptEngine::Started</tt> - The script can execute code, but does not yet handle events
|
||
|
|
<li><tt>QAxScriptEngine::Connected</tt> - The script can execute code and is connected so
|
||
|
|
that it can handle events
|
||
|
|
<li><tt>QAxScriptEngine::Disconnected</tt> - The script is loaded, but is not connected to
|
||
|
|
event sources
|
||
|
|
<li><tt>QAxScriptEngine::Closed</tt> - The script has been closed.
|
||
|
|
</ul>

|
|
<h3 class=fn><a name="QAxScriptEngine"></a>QAxScriptEngine::QAxScriptEngine ( const <a href="qstring.html">QString</a> & language, <a href="qaxscript.html">QAxScript</a> * script )
|
||
|
|
</h3>
|
||
|
|
Constructs a QAxScriptEngine 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">QAxScript</a>
|
||
|
|
class when <a href="qaxscript.html#load">loading a script</a>.
|
||
|
|
<p> Instances of QAxScriptEngine should always have both a language and a
|
||
|
|
script.
|
||
|
|
|
||
|
|
<h3 class=fn><a name="~QAxScriptEngine"></a>QAxScriptEngine::~QAxScriptEngine ()
|
||
|
|
</h3>
|
||
|
|
Destroys the QAxScriptEngine object, releasing all allocated
|
||
|
|
resources.
|
||
|
|
|
||
|
|
<h3 class=fn>void <a name="addItem"></a>QAxScriptEngine::addItem ( const <a href="qstring.html">QString</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>QAxScriptEngine::hasIntrospection () const
|
||
|
|
</h3>
|
||
|
|
Returns TRUE if the script engine supports introspection;
|
||
|
|
otherwise returns FALSE.
|
||
|
|
|
||
|
|
<h3 class=fn>bool <a name="isValid"></a>QAxScriptEngine::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>QAxScriptEngine::queryInterface ( const <a href="quuid.html">QUuid</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="qstring.html">QString</a> <a name="scriptLanguage"></a>QAxScriptEngine::scriptLanguage () const
|
||
|
|
</h3>
|
||
|
|
Returns the scripting language, for example "VBScript",
|
||
|
|
or "JScript".
|
||
|
|
|
||
|
|
<h3 class=fn>void <a name="setState"></a>QAxScriptEngine::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>QAxScriptEngine::state () const
|
||
|
|
</h3>
|
||
|
|
Returns the state of the script engine.
