Here is what we hope to do : if you select one of both item and push the “Click Me” button you obtain the result of the selection as result :
Selected Item Pos :-1 Selected Item Pos :1 Selected Item Pos :0
The first line is obtained when nothing is selected in the list box. To learn what we can do with this list box, we first present the IDL file of the XListBox interface :
//Listing 28 XListBox Interface : IDL File
// IDL
module com { module sun { module star { module awt {
interface XListBox: com::sun::star::uno::XInterface
{
[oneway] void addItemListener( [in] com::sun::star::awt::XItemListener l );
[oneway] void removeItemListener( [in] com::sun::star::awt::XItemListener l );
[oneway] void addActionListener( [in] com::sun::star::awt::XActionListener l );
[oneway] void removeActionListener( [in] com::sun::star::awt::XActionListener l );
[oneway] void addItem( [in] string aItem,
[in] short nPos );
[oneway] void addItems( [in] sequence<string> aItems,
[in] short nPos );
[oneway] void removeItems( [in] short nPos,
[in] short nCount );
short getItemCount();
string getItem( [in] short nPos );
sequence<string> getItems();
short getSelectedItemPos();
sequence<short> getSelectedItemsPos();
string getSelectedItem();
sequence<string> getSelectedItems();
[oneway] void selectItemPos( [in] short nPos,
[in] boolean bSelect );
[oneway] void selectItemsPos( [in] sequence<short> aPositions,
[in] boolean bSelect );
[oneway] void selectItem( [in] string aItem,
[in] boolean bSelect );
boolean isMutipleMode();
[oneway] void setMultipleMode( [in] boolean bMulti );
short getDropDownLineCount();
[oneway] void setDropDownLineCount( [in] short nLines );
[oneway] void makeVisible( [in] short nEntry );
};
}; }; }; };
We focus our attention now on the C++ code.
First create an event listener :
[cpp]
//Listing 29 Our new Action performed Listener
// C++
// Don't forget the #include <cppuhelper/implbase1.hxx>
typedef ::cppu::WeakImplHelper1< ::com::sun::star::awt::XActionListener > ActionListenerHelper;
/** action listener
- /
class ActionListenerImpl : public ActionListenerHelper { private : sal_Int32 _nCounts; Reference< XControlContainer > _xControlCont; //XControlContainer _xControlCont;
public :
ActionListenerImpl(const Reference< XControlContainer >& xControlCont) { _xControlCont = xControlCont; _nCounts = 0; }
// XEventListener
virtual void SAL_CALL disposing (const com::sun::star::lang::EventObject& aEventObj ) throw(::com::sun::star::uno::RuntimeException) {
// _xControlCont = NULL; printf("object listened to will be disposed\n"); }
// XActionListener virtual void SAL_CALL actionPerformed (const ::com::sun::star::awt::ActionEvent& rEvent ) throw ( RuntimeException) { OUString OUStr; // set label text Reference< XControl > xListControl = _xControlCont->getControl(OUString::createFromAscii("Label1")); // from adipan Reference< XListBox> xPSetListBox(xListControl,UNO_QUERY); sal_Int16 selItem = xPSetListBox->getSelectedItemPos (); printf ("Selected Item Pos :%d\n", selItem);
}
};
This event listener will be associated with the “Click Me” button. The printf instruction recalls us we have to have a look in the shell windows when clicking.
The complete dialog is constructed in the main(). It would be probably better with subprogram (maybe later).
