|
||
|
|
<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 TQAxWidget class is a <a href="qwidget.html">TQWidget</a> that wraps an ActiveX control.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> A TQAxWidget can be instantiated as an empty object, with the name
|
||
|
|
of the ActiveX control it should wrap, or with an existing
|
||
|
|
interface pointer to the ActiveX control. The ActiveX control's
|
||
|
|
properties, methods and events which only use <a href="qaxbase.html">supported data types</a>, become available as TQt properties,
|
||
|
|
slots and signals. The base class <a href="qaxbase.html">TQAxBase</a> provides an API to
|
||
|
|
access the ActiveX directly through the IUnknown pointer.
|
||
|
|
<p> TQAxWidget is a TQWidget and can be used as such, e.g. it can be
|
||
|
|
organized in a widget hierarchy, receive events or act as an event
|
||
|
|
filter. Standard widget properties, e.g. <a href="qwidget.html#enabled-prop">enabled</a> are supported, but it depends on the ActiveX
|
||
|
|
control to implement support for ambient properties like e.g.
|
||
|
|
palette or font. TQAxWidget tries to provide the necessary hints.
|
||
|
|
<p> <b>Warning:</b>
|
||
|
|
You can subclass TQAxWidget, but you cannot use the <a href="metaobjects.html#Q_OBJECT">Q_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 TQAxWidget as a member of the
|
||
|
|
<a href="qobject.html">TQObject</a> subclass.
|
||

<h3 class=fn><a name="TQAxWidget"></a>TQAxWidget::TQAxWidget ( <a href="qwidget.html">TQWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 )
|
||
|
|
</h3>
|
||
|
|
Creates an empty TQAxWidget widget and propagates <em>parent</em>, <em>name</em> and <em>f</em> to the <a href="qwidget.html">TQWidget</a> constructor. To initialize a control,
|
||
|
|
call <a href="qaxbase.html#setControl">setControl</a>.
|
||
|
|
|
||
|
|
<h3 class=fn><a name="TQAxWidget-2"></a>TQAxWidget::TQAxWidget ( const <a href="qstring.html">TQString</a> & c, <a href="qwidget.html">TQWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 )
|
||
|
|
</h3>
|
||
|
|
Creates an TQAxWidget widget and initializes the ActiveX control <em>c</em>.
|
||
|
|
<em>parent</em>, <em>name</em> and <em>f</em> are propagated to the <a href="qwidget.html">TQWidget</a> contructor.
|
||
|
|
<p> <p>See also <a href="qaxbase.html#control-prop">control</a>.
|

<h3 class=fn><a name="TQAxWidget-3"></a>TQAxWidget::TQAxWidget ( IUnknown * iface, <a href="qwidget.html">TQWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 )
|
||
|
|
</h3>
|
||
|
|
Creates a TQAxWidget that wraps the COM object referenced by <em>iface</em>.
|
||
|
|
<em>parent</em>, <em>name</em> and <em>f</em> are propagated to the <a href="qwidget.html">TQWidget</a> contructor.
|
||
|
|
|
||
|
|
<h3 class=fn><a name="~TQAxWidget"></a>TQAxWidget::~TQAxWidget ()
|
||
|
|
</h3>
|
||
|
|
Shuts down the ActiveX control and destroys the TQAxWidget widget,
|
||
|
|
cleaning up all allocated resources.
|
||
|
|
<p> <p>See also <a href="qaxbase.html#clear">clear</a>().
|
||
|
|
|
||
|
|
<h3 class=fn>bool <a name="createHostWindow"></a>TQAxWidget::createHostWindow ( bool initialized )<tt> [virtual protected]</tt>
|
||
|
|
</h3>
|
||
|
|
Creates the client site for the ActiveX control, and returns TRUE if
|
||
|
|
the control could be embedded successfully, otherwise returns FALSE.
|
||
|
|
If <em>initialized</em> is TRUE the control has already been initialized.
|
||
|
|
<p> This function is called by <a href="qaxbase.html#initialize">initialize</a>(). If you reimplement initialize
|
||
|
|
to customize the actual control instantiation, call this function in your
|
||
|
|
reimplementation to have the control embedded by the default client side.
|
||
|
|
Creates the client site for the ActiveX control, and returns TRUE if
|
||
|
|
the control could be embedded successfully, otherwise returns FALSE.

|
||
|
|
</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="qvariant.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="qobject.html#connect">TQObject::connect</a>() call.
|
||
|
|
<pre>
|
||
|
|
activeX->dynamicCall( "Navigate(const <a href="qstring.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="qstring.html">TQString</a> text = activeX->dynamicCall( "Text" ).toString();
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
Note that it is faster to get and set properties using
|
||
|
|
<a href="qobject.html#property">TQObject::property</a>() and <a href="qobject.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="qvariant.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="qvariant.html">TQVariant</a> <a name="dynamicCall-2"></a>TQAxBase::dynamicCall ( const <a href="qcstring.html">TQCString</a> & function, <a href="qvaluelist.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="qvariant.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="qcstring.html">TQCString</a> & name, 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>
|
||
|
|
Returns a pointer to a <a href="qaxobject.html">TQAxObject</a> 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 TQAxWidget), 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>
|
||
|
|
TQAxWidget outlook( "Outlook.Application" );
|
||
|
|
<a href="qaxobject.html">TQAxObject</a> *session = outlook.<a href="qaxbase.html#querySubObject">querySubObject</a>( "Session" );
|
||
|
|
if ( session ) {
|
||
|
|
<a href="qaxobject.html">TQAxObject</a> *defFolder = session-><a href="qaxbase.html#querySubObject">querySubObject</a>(
|
||
|
|
"GetDefaultFolder(OlDefaultFolders)",
|
||
|
|
"olFolderContacts" );
|
||
|
|
//...
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
|
||
|
|
<p>Example: <a href="qaxcontainer-example-qutlook.html#x2721">qutlook/centralwidget.cpp</a>.
|
||
|
|
<h3 class=fn>bool <a name="translateKeyEvent"></a>TQAxWidget::translateKeyEvent ( int message, int keycode ) const<tt> [virtual protected]</tt>
|
||
|
|
</h3>
|
||
|
|
Reimplement this function to pass certain key events to the
|
||
|
|
ActiveX control. <em>message</em> is the Window message identifier
|
||
|
|
specifying the message type (ie. WM_KEYDOWN), and <em>keycode</em> is
|
||
|
|
the virtual keycode (ie. VK_TAB).
|
||
|
|
<p> If the function returns TRUE the key event is passed on to the
|
||
|
|
ActiveX control, which then either processes the event or passes
|
||
|
|
the event on to TQt.
|
||
|
|
<p> If the function returns FALSE the processing of the key event is
|
||
|
|
ignored by <a href="activeqt.html#ActiveTQt">ActiveTQt</a>, ie. the ActiveX control might handle it or
|
||
|
|
not.
|
||
|
|
<p> The default implementation returns TRUE for the following cases:
|
||
|
|
<p> <center><table cellpadding="4" cellspacing="2" border="0">
|
||
|
|
<tr bgcolor="#a2c511">

|
||
|
|
VK_CONTROL or VK_MENU
|
||
|
|
</table></center>
|
||
|
|
<p> This table is the result of experimenting with popular ActiveX controls,
|
||
|
|
ie. Internet Explorer and Microsoft Office applications, but for some
|
||
|
|
controls it might retquire modification.
