<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 TQAxObject class provides a <a href="tqobject.html">TQObject</a> that wraps a COM object.
|
|
|
|
<p>
|
|
|
|
<p> A TQAxObject can be instantiated as an empty object, with the name
|
|
of the COM object it should wrap, or with a pointer to the
|
|
IUnknown that represents an existing COM object. If the COM object
|
|
implements the IDispatch interface, the properties, methods and
|
|
events of that object become available as TQt properties, slots and
|
|
signals. The base class, <a href="qaxbase.html">TQAxBase</a>, provides an API to access the
|
|
COM object directly through the IUnknown pointer.
|
|
<p> TQAxObject is a TQObject and can be used as such, e.g. it can be
|
|
organized in an object hierarchy, receive events and connect to
|
|
signals and slots.
|
|
<p> <b>Warning:</b>
|
|
You can subclass TQAxObject, but you cannot use the <a href="metaobjects.html#TQ_OBJECT">TQ_OBJECT</a> macro
|
|
in the subclass (the generated <a href="moc.html#moc">moc</a>-file will not compile), so you
|
|
cannot add further signals, slots or properties. This limitation is
|
|
due to the metaobject information generated in runtime.
|
|
To work around this problem, aggregate the TQAxObject as a member of
|
|
the <a href="tqobject.html">TQObject</a> subclass.

</h3>
|
|
Creates an empty COM object and propagates <em>parent</em> and <em>name</em>
|
|
to the <a href="tqobject.html">TQObject</a> constructor. To initialize the object, call <a href="qaxbase.html#setControl">setControl</a>.

<h3 class=fn><a name="TQAxObject-2"></a>TQAxObject::TQAxObject ( const <a href="tqstring.html">TQString</a> & c, <a href="tqobject.html">TQObject</a> * parent = 0, const char * name = 0 )
|
|
</h3>
|
|
Creates a TQAxObject that wraps the COM object <em>c</em>. <em>parent</em> and
|
|
<em>name</em> are propagated to the <a href="tqwidget.html">TQWidget</a> contructor.
|
|
<p> <p>See also <a href="qaxbase.html#control-prop">control</a>.

|
<h3 class=fn><a name="TQAxObject-3"></a>TQAxObject::TQAxObject ( IUnknown * iface, <a href="tqobject.html">TQObject</a> * parent = 0, const char * name = 0 )
|
|
</h3>
|
|
Creates a TQAxObject that wraps the COM object referenced by <em>iface</em>. <em>parent</em> and <em>name</em> are propagated to the <a href="tqobject.html">TQObject</a>
|
|
contructor.
|
|
|
|
<h3 class=fn><a name="~TQAxObject"></a>TQAxObject::~TQAxObject ()
|
|
</h3>
|
|
Releases the COM object and destroys the TQAxObject,
|
|
cleaning up all allocated resources.
|
|
|
|
<h3 class=fn><a href="ntqvariant.html">TQVariant</a> <a name="dynamicCall"></a>TQAxBase::dynamicCall ( const <a href="ntqcstring.html">TQCString</a> & function, const <a href="ntqvariant.html">TQVariant</a> & var1 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var2 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var3 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var4 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var5 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var6 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var7 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var8 = TQVariant ( ) )
|
|
</h3>
|
|
Calls the COM object's method <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>, and returns the value returned by
|
|
the method, or an invalid <a href="ntqvariant.html">TQVariant</a> if the method does not return
|
|
a value or when the function call failed.
|
|
<p> If <em>function</em> is a method of the object the string must be provided
|
|
as the full prototype, for example as it would be written in a
|
|
<a href="tqobject.html#connect">TQObject::connect</a>() call.
|
|
<pre>
|
|
activeX->dynamicCall( "Navigate(const <a href="tqstring.html">TQString</a>&)", "www.trolltech.com" );
|
|
</pre>
|
|
|
|
<p> Alternatively a function can be called passing the parameters embedded
|
|
in the string, e.g. above function can also be invoked using
|
|
<pre>
|
|
activeX->dynamicCall("Navigate(\"www.trolltech.com\");
|
|
</pre>
|
|
|
|
All parameters are passed as strings; it depends on the control whether
|
|
they are interpreted correctly, and is slower than using the prototype
|
|
with correctly typed parameters.
|
|
<p> If <em>function</em> is a property the string has to be the name of the
|
|
property. The property setter is called when <em>var1</em> is a valid TQVariant,
|
|
otherwise the getter is called.
|
|
<pre>
|
|
activeX->dynamicCall( "Value", 5 );
|
|
<a href="tqstring.html">TQString</a> text = activeX->dynamicCall( "Text" ).toString();
|
|
</pre>
|
|
|
|
Note that it is faster to get and set properties using
|
|
<a href="tqobject.html#property">TQObject::property</a>() and <a href="tqobject.html#setProperty">TQObject::setProperty</a>().
|
|
<p> It is only possible to call functions through <a href="qaxbase.html#dynamicCall">dynamicCall</a>() that
|
|
have parameters or return values of datatypes supported by
|
|
<a href="ntqvariant.html">TQVariant</a>. See the <a href="qaxbase.html">TQAxBase</a> class documentation for a list of
|
|
supported and unsupported datatypes. If you want to call functions
|
|
that have unsupported datatypes in the parameter list, use
|
|
<a href="qaxbase.html#queryInterface">queryInterface</a>() to retrieve the appropriate COM interface, and
|
|
use the function directly.
|
|
<p> <pre>
|
|
IWebBrowser2 *webBrowser = 0;
|
|
activeX->queryInterface( IID_IWebBrowser2, (void**)&webBrowser );
|
|
if ( webBrowser ) {
|
|
webBrowser->Navigate2( pvarURL );
|
|
webBrowser->Release();
|
|
}
|
|
</pre>
|
|
|
|
<p> This is also more efficient.
|
|
|
|
<p>Example: <a href="qaxcontainer-example-qutlook.html#x2720">qutlook/centralwidget.cpp</a>.
|
|
<h3 class=fn><a href="ntqvariant.html">TQVariant</a> <a name="dynamicCall-2"></a>TQAxBase::dynamicCall ( const <a href="ntqcstring.html">TQCString</a> & function, <a href="tqvaluelist.html">TQValueList</a><TQVariant> & vars )
|
|
</h3>
|
|
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|
<p> Calls the COM object's method <em>function</em>, passing the
|
|
parameters in <em>vars</em>, and returns the value returned by
|
|
the method. If the method does not return a value or when
|
|
the function call failed this function returns an invalid
|
|
<a href="ntqvariant.html">TQVariant</a> object.
|
|
<p> The TQVariant objects in <em>vars</em> are updated when the method has
|
|
out-parameters.
|
|
|
|
<h3 class=fn><a href="qaxobject.html">TQAxObject</a> * <a name="querySubObject"></a>TQAxBase::querySubObject ( const <a href="ntqcstring.html">TQCString</a> & name, const <a href="ntqvariant.html">TQVariant</a> & var1 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var2 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var3 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var4 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var5 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var6 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var7 = TQVariant ( ), const <a href="ntqvariant.html">TQVariant</a> & var8 = TQVariant ( ) )
|
|
</h3>
|
|
Returns a pointer to a TQAxObject wrapping the COM object provided
|
|
by the method or property <em>name</em>, passing 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>.
|
|
<p> If <em>name</em> is provided by a method the string must include the
|
|
full function prototype.
|
|
<p> If <em>name</em> is a property the string must be the name of the property,
|
|
and <em>var1</em>, ... <em>var8</em> are ignored.
|
|
<p> The returned TQAxObject is a child of this object (which is either of
|
|
type TQAxObject or <a href="qaxwidget.html">TQAxWidget</a>), and is deleted when this object is
|
|
deleted. It is however safe to delete the returned object yourself,
|
|
and you should do so when you iterate over lists of subobjects.
|
|
<p> COM enabled applications usually have an object model publishing
|
|
certain elements of the application as dispatch interfaces. Use
|
|
this method to navigate the hierarchy of the object model, e.g.
|
|
<p> <pre>
|
|
<a href="qaxwidget.html">TQAxWidget</a> outlook( "Outlook.Application" );
|
|
TQAxObject *session = outlook.<a href="qaxbase.html#querySubObject">querySubObject</a>( "Session" );
|
|
if ( session ) {
|
|
TQAxObject *defFolder = session-><a href="qaxbase.html#querySubObject">querySubObject</a>(
|
|
"GetDefaultFolder(OlDefaultFolders)",
|
|
"olFolderContacts" );
|
|
//...
|
|
}
|
|
</pre>
|
|
|
|
