First Dialog

Let's give now a complete translation of SampleDialog.java example. You can find it in <OpenOffice.org1.1_SDK>/examples/DevelopersGuide/BasicAndDialogs/CreatingDialogs This is a dialog box with a “Click Me” button. When you click this button it increments a counter and prints out the result in the dialog box. I have done this example in few hours starting from the previous one. Without GAP (from India) 's help it would be a few months postponed. This example is constructed as usually, without helper (using the style defined in chapter 4.3 “Prepare a new code as a starting point”) Here are the listings : we begin with the event listener : [cpp] //Listing 18 The Action performed Event Listener // C++ 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) { // increase click counter _nCounts++; // printf("OK :  %d\n",_nCounts); OLD listener OUString OUStr; // set label text Reference< XControl > label = _xControlCont->getControl(OUString::createFromAscii("Label1"));

// Don't forget to add : #include <com/sun/star/awt/XFixedText.hpp> // Don't forget to add "com.sun.star.awt.XFixedText \" in the makefile Reference< XFixedText > xLabel(label,UNO_QUERY); xLabel->setText (OUString::createFromAscii("Text1 ") + OUStr.valueOf((sal_Int32)_nCounts));

}

}; What differs from the previous one is only the action performed method where we replace a printf (or cout<<) with a setText. We don't print out in the shell windows but in the dialog box windows. Let's have a look in the corresponding IDL file :

//Listing 19 XFixedText Interface : IDL File 
// IDL
module com {  module sun {  module star {  module awt {
interface XFixedText: com::sun::star::uno::XInterface
{
	[oneway] void setText( [in] string Text );
	string getText();
	/** sets the alignment of the text in the control.
		<pre>
		0: left
		1: center
		2: right
	 */
	[oneway] void setAlignment( [in] short nAlign ); 
 	short getAlignment(); 
 
};
}; }; }; };  

We are ready to construct and use the dialog box now. Here is the listing (we don't give the ooConnect() procedure already given many times in this document. [cpp] //Listing 20 The complete Code // C++ main( ) { //retrieve an instance of the remote service manager Reference< XMultiServiceFactory > xServiceManager;

   	xServiceManager = ooConnect();
   	if( xServiceManager.is() ){
       	printf( "Connected sucessfully to the office\n" );
   	}

//get the desktop service using createInstance returns an XInterface type

   	Reference< XInterface  > Desktop = xServiceManager->createInstance(
   		OUString::createFromAscii( "com.sun.star.frame.Desktop" ));

//query for the XComponentLoader interface

   	Reference< XComponentLoader > rComponentLoader (Desktop, UNO_QUERY);
   	if( rComponentLoader.is() ){
       	printf( "XComponentloader successfully instanciated\n" );
   	}

Reference< XInterface > xdialogModel = xServiceManager->createInstance( OUString::createFromAscii("com.sun.star.awt.UnoControlDialogModel")); if (xdialogModel.is()) printf("OK XDialogModel\n"); else printf("Error ... XDialodModel\n");
