<h2>Detailed Description</h2>
<p>The QAxScriptManager class provides a bridge between application objects and script code.</p>
<p>The QAxScriptManager acts as a bridge between the COM objects embedded in the Qt application through <a href="qaxobject.html">QAxObject</a> or <a href="qaxwidget.html">QAxWidget</a>, and the scripting languages available through the Windows Script technologies, usually JScript and VBScript.</p>
<p>Create one QAxScriptManager for each separate document in your application, and add the COM objects the scripts need to access using <a href="qaxscriptmanager.html#addObject">addObject</a>(). Then <a href="qaxscriptmanager.html#load">load</a>() the script sources and invoke the functions using <a href="qaxscriptmanager.html#call">call</a>().</p>
<p><b>Warning:</b> This class is not available with the bcc5.5 and MingW compilers.</p>

<p>Creates a <a href="qaxscriptmanager.html">QAxScriptManager</a> object. <i>parent</i> is passed on to the <a href="qobject.html">QObject</a> constructor.</p>
<p>It is usual to create one <a href="qaxscriptmanager.html">QAxScriptManager</a> for each document in an application.</p>
<!-- @@@QAxScriptManager -->
<!-- $$$~QAxScriptManager[overload1]$$$~QAxScriptManager -->
<h3 class="fn"><a name="dtor.QAxScriptManager"></a>QAxScriptManager::<span class="name">~QAxScriptManager</span> ()</h3>

<p>Adds <i>object</i> to the manager. Scripts handled by this manager can access the object in the code using the object's <a href="qobject.html#objectName-prop">objectName</a> property.</p>
<p>You must add all the necessary objects before loading any scripts.</p>
<!-- @@@addObject -->
<!-- $$$addObject$$$addObjectQObject* -->
<h3 class="fn"><a name="addObject-2"></a><span class="type">void</span> QAxScriptManager::<span class="name">addObject</span> ( <span class="type"><a href="qobject.html">QObject</a></span> * <i>object</i> )</h3>
<p>This is an overloaded function.</p>
<p>Adds a generic COM wrapper for <i>object</i> to the manager. <i>object</i> must be exposed as a COM object using the functionality provided by the <a href="qaxserver.html">QAxServer</a> module. Applications using this function you must link against the qaxserver library.</p>

<p>Calls <i>function</i>, passing the parameters <i>var1</i>, <i>var1</i>, <i>var2</i>, <i>var3</i>, <i>var4</i>, <i>var5</i>, <i>var6</i>, <i>var7</i> and <i>var8</i> as arguments and returns the value returned by the function, or an invalid <a href="qvariant.html">QVariant</a> if the function does not return a value or when the function call failed. The call returns when the script's execution has finished.</p>
<p>In most script engines the only supported parameter type is "const <a href="qvariant.html">QVariant</a>&", for example, to call a JavaScript function</p>
<pre class="cpp"> function setNumber(number)
{
n <span class="operator">=</span> number;
}</pre>
<p>use</p>
<pre class="cpp"> <span class="type">QValueList</span> args;

script<span class="operator">-</span><span class="operator">></span>call(<span class="string">"setNumber(const QVariant&)"</span><span class="operator">,</span> args);</pre>
<p>As with <a href="qaxbase.html#dynamicCall">dynamicCall</a> the parameters can directly be embedded in the function string.</p>
<pre class="cpp"> script<span class="operator">-</span><span class="operator">></span>call(<span class="string">"setNumber(5)"</span>);</pre>
<p>However, this is slower.</p>
<p>Functions provided by script engines that don't support introspection are not available and must be called directly using <a href="qaxscript.html#call">QAxScript::call</a>() on the respective <a href="qaxscriptmanager.html#script">script</a> object.</p>
<p>Note that calling this function can be significantely slower than using call() on the respective <a href="qaxscript.html">QAxScript</a> directly.</p>

<p>Loads the script source <i>code</i> using the script engine for <i>language</i>. The script can later be referred to using its <i>name</i> which should not be empty.</p>
<p>The function returns a pointer to the script for the given <i>code</i> if the <i>code</i> was loaded successfully; otherwise it returns 0.</p>
<p>If <i>language</i> is empty it will be determined heuristically. If <i>code</i> contains the string "End Sub" it will be interpreted as VBScript, otherwise as JScript. Additional script engines can be registered using <a href="qaxscriptmanager.html#registerEngine">registerEngine</a>().</p>
<p>You must add all the objects necessary (using <a href="qaxscriptmanager.html#addObject">addObject</a>()) <i>before</i> loading any scripts. If <i>code</i> declares a function that is already available (no matter in which language) the first function is overloaded and can no longer be called via <a href="qaxscriptmanager.html#call">call</a>(); but it will still be available by calling its <a href="qaxscriptmanager.html#script">script</a> directly.</p>

<p>The function returns a pointer to the script engine for the code in <i>file</i> if <i>file</i> was loaded successfully; otherwise it returns 0.</p>
<p>The script engine used is determined from the file's extension. By default ".js" files are interpreted as JScript files, and ".vbs" and ".dsm" files are interpreted as VBScript.
