This example is a modified version of the standard 
<a href="addressbook-example.html">TQt addressbook</a> example.
<p> It demonstrates the use of <a href="qaxobject.html">TQAxObject</a> and querySubObject to instantiate and
navigate the Outlook Object Model, and the use of the TQt property system to 
read and write values of items in the Outlook contact folder.
<p> 

The modifications in the class declaration of the central widget are
a forward declaration of the TQAxObject class and the IDispatch interface, 
and a new <a href="qlistviewitem.html">TQListViewItem</a> subclass <tt>ABListViewItem</tt> that implements a 
constructor and a destructor and has a member <tt>contact_item</tt> of type 
<a href="qaxobject.html">TQAxObject</a>.
<pre>    class TQAxObject;
    struct IDispatch;

    class ABListViewItem : public <a href="qlistviewitem.html">TQListViewItem</a>
    {
    public:
        ABListViewItem( <a href="qlistview.html">TQListView</a> *listview, TQString firstName, TQString lastName, TQString address, TQString eMail, TQAxObject *contact );
        ~ABListViewItem();

        <a href="qaxobject.html">TQAxObject</a> *contactItem() const;

    private:
        <a href="qaxobject.html">TQAxObject</a> *contact_item;
    };
</pre>
<p> The ABCentralWidget gets a destructor, a new protected function <tt>setupOutlook</tt>,
a new protected slot <tt>updateOutlook</tt>, and also three members of type <a href="qaxobject.html">TQAxObject</a>.
<pre>        void findEntries();

        void updateOutlook();

    protected:
        void setupTabWidget();
        void setupListView();
        void setupOutlook();

        <a href="qaxobject.html">TQAxObject</a> *outlook, *outlookSession, *contactItems;

        <a href="qgridlayout.html">TQGridLayout</a> *mainGrid;
</pre>
<p> 

The implementation of the ABListViewItem class is trivial:
<pre>    ABListViewItem::ABListViewItem( <a href="qlistview.html">TQListView</a> *listview,
                                    <a href="qstring.html">TQString</a> firstName,
                                    <a href="qstring.html">TQString</a> lastName,
                                    <a href="qstring.html">TQString</a> address,
                                    <a href="qstring.html">TQString</a> eMail,
                                    <a href="qaxobject.html">TQAxObject</a> *contact )
    : <a href="qlistviewitem.html">TQListViewItem</a>( listview, firstName, lastName, address, eMail ), contact_item( contact )
    {
    }

    ABListViewItem::~ABListViewItem()
    {
        delete contact_item;
    }

    TQAxObject *ABListViewItem::contactItem() const
    {
        return contact_item;
    }
</pre>The ABCentralWidget constructor initializes the <a href="qaxobject.html">TQAxObject</a> pointers to zero and 
calls the <tt>setupOutlook</tt> function. The ABCentralWidget destructor calls the
Logoff method of the outlookSession object.
<pre>    ABCentralWidget::ABCentralWidget( <a href="qwidget.html">TQWidget</a> *parent, const char *name )
        : <a href="qwidget.html">TQWidget</a>( parent, name ), outlook( 0 ), outlookSession( 0 ), contactItems( 0 )
    {
        mainGrid = new <a href="qgridlayout.html">TQGridLayout</a>( this, 2, 1, 5, 5 );

        setupTabWidget();
        setupListView();
        setupOutlook();

    <a name="x2722"></a>    mainGrid-&gt;<a href="qgridlayout.html#setRowStretch">setRowStretch</a>( 0, 0 );
        mainGrid-&gt;<a href="qgridlayout.html#setRowStretch">setRowStretch</a>( 1, 1 );
    }

    ABCentralWidget::~ABCentralWidget()
    {
        if ( outlookSession )
            outlookSession-&gt;dynamicCall( "Logoff()" );
    }
</pre>The <tt>setupOutlook</tt> implementation creates a TQAxObject to wrap the
Outlook.Application COM object.
<pre>    void ABCentralWidget::setupOutlook()
    {
        outlook = new <a href="qaxobject.html">TQAxObject</a>( "Outlook.Application", this );
</pre>The call to <tt>querySubObject</tt> returns a new <a href="qaxobject.html">TQAxObject</a> wrapper around the 
"Session" object of the Outlook Object hierarchy. If the call fails for 
some reason setupOutlook returns, otherwise it calls the "Logon" method 
of the Session object.
<pre>        // Get a session object
    <a name="x2721"></a>    outlookSession = outlook-&gt;<a href="qaxbase.html#querySubObject">querySubObject</a>( "Session" );
        if ( !outlookSession )
            return;
        // Login; doesn't hurt if you are already running and logged on...
        outlookSession-&gt;dynamicCall( "Logon()" );
</pre>The following call to <tt>querySubObject</tt> returns a new TQAxObject wrapper
around the default folder for "contacts".
<pre>        // Get the default folder for contacts
        <a href="qaxobject.html">TQAxObject</a> *defFolder = outlookSession-&gt;querySubObject( "GetDefaultFolder(OlDefaultFolders)", "olFolderContacts" );
</pre><tt>querySubObject</tt> is then used again to get the list of all items in the
folder. The <tt>connect</tt> statement connects the new ABCentralWidget slot
to the signals provided by the "Items" COM object. Finally, it calls the
<tt>updateOutlook</tt> function to populate the listview.
<pre>        // Get all items
        if ( defFolder ) {
            contactItems = defFolder-&gt;<a href="qaxbase.html#querySubObject">querySubObject</a>( "Items" );
            <a href="qobject.html#connect">connect</a>( contactItems, SIGNAL(ItemAdd(IDispatch*)), this, SLOT(updateOutlook()) );
            <a href="qobject.html#connect">connect</a>( contactItems, SIGNAL(ItemChange(IDispatch*)), this, SLOT(updateOutlook()) );
            <a href="qobject.html#connect">connect</a>( contactItems, SIGNAL(ItemRemove()), this, SLOT(updateOutlook()) );
        }

        updateOutlook();
    }
</pre>
<p> The implementation of the <tt>updateOutlook</tt> slot clears the listview, and uses
<tt>querySubObject</tt> to iterate through the list of items. For every item provided a new
ABListViewItem object is created and filled with the properties of the item
object. The object returned by <tt>querySubObject</tt> is a child of the callee (ie. "contactItems"), 
but the list view item should take ownership to provide a cleaner relation between 
entries, so the item has to be removed from its parent object.
<pre>    void ABCentralWidget::updateOutlook()
    {
    <a name="x2725"></a>    listView-&gt;<a href="qlistview.html#clear">clear</a>();
        if ( !contactItems )
            return;

        <a href="qaxobject.html">TQAxObject</a> *item = contactItems-&gt;querySubObject( "GetFirst()" );
        while ( item ) {
    <a name="x2729"></a>        <a href="qstring.html">TQString</a> firstName = item-&gt;<a href="qobject.html#property">property</a>( "FirstName" ).toString();
            <a href="qstring.html">TQString</a> lastName = item-&gt;<a href="qobject.html#property">property</a>( "LastName" ).toString();
            <a href="qstring.html">TQString</a> address = item-&gt;<a href="qobject.html#property">property</a>( "HomeAddress" ).toString();
            <a href="qstring.html">TQString</a> email = item-&gt;<a href="qobject.html#property">property</a>( "Email1Address" ).toString();

            (void)new ABListViewItem( listView, firstName, lastName, address, email, item );
            // the listviewitem takes ownership
    <a name="x2727"></a>        item-&gt;<a href="qlistviewitem.html#parent">parent</a>()-&gt;removeChild( item );

            item = contactItems-&gt;querySubObject( "GetNext()" );
        }
    }
</pre>
<p> The <tt>addEntry</tt> implementation calls the CreateItem method of the Outlook.Application
object to create a new contact item, and creates a new ABListViewItem if the call
succeeds.
<pre>    void ABCentralWidget::addEntry()
    {
    <a name="x2724"></a>    if ( !iFirstName-&gt;<a href="qlineedit.html#text">text</a>().isEmpty() || !iLastName-&gt;<a href="qlineedit.html#text">text</a>().isEmpty() ||
             !iAddress-&gt;<a href="qlineedit.html#text">text</a>().isEmpty() || !iEMail-&gt;<a href="qlineedit.html#text">text</a>().isEmpty() ) {
            <a href="qaxobject.html">TQAxObject</a> *contactItem = outlook-&gt;<a href="qaxbase.html#querySubObject">querySubObject</a>( "CreateItem(OlItemType)", "olContactItem" );
            if ( contactItem ) {
    <a name="x2730"></a>            contactItem-&gt;<a href="qobject.html#setProperty">setProperty</a>( "FirstName", iFirstName-&gt;<a href="qlineedit.html#text">text</a>() );
                contactItem-&gt;<a href="qobject.html#setProperty">setProperty</a>( "LastName", iLastName-&gt;<a href="qlineedit.html#text">text</a>() );
                contactItem-&gt;<a href="qobject.html#setProperty">setProperty</a>( "HomeAddress", iAddress-&gt;<a href="qlineedit.html#text">text</a>() );
                contactItem-&gt;<a href="qobject.html#setProperty">setProperty</a>( "Email1Address", iEMail-&gt;<a href="qlineedit.html#text">text</a>() );
    <a name="x2720"></a>            contactItem-&gt;<a href="qaxbase.html#dynamicCall">dynamicCall</a>( "Save()" );

                new ABListViewItem( listView, iFirstName-&gt;<a href="qlineedit.html#text">text</a>(),
                    iLastName-&gt;<a href="qlineedit.html#text">text</a>(), iAddress-&gt;<a href="qlineedit.html#text">text</a>(), iEMail-&gt;<a href="qlineedit.html#text">text</a>(), contactItem );
            }
        }

    <a name="x2723"></a>    iFirstName-&gt;<a href="qlineedit.html#setText">setText</a>( "" );
        iLastName-&gt;<a href="qlineedit.html#setText">setText</a>( "" );

        iEMail-&gt;<a href="qlineedit.html#setText">setText</a>( "" );
    }
</pre>
<p> The <tt>changeEntry</tt> implementation updates the values in the contact item of the current
listview item as well as the values of the listview item itself.
<pre>    void ABCentralWidget::changeEntry()
    {
    <a name="x2726"></a>    ABListViewItem *item = (ABListViewItem*)listView-&gt;<a href="qlistview.html#currentItem">currentItem</a>();
