First Dialog
From Apache OpenOffice Wiki
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.
//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" );
}
