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.

Edit-find-replace.png This article should be checked for accuracy and conformity to style.

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 (See com.sun.star.awt.XActionListener, com.sun.star.awt.XControlContainer com.sun.star.awt.XFixedText interfaces) :

//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 (see also com.sun.star.awt.XFixedText):

//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.
