QSingleApplication

[TheKedge]

Hello all,
Can somebody tell me what's going on with my single app? Both the app.SendMessage() and the app.isRunning() below, return false always. Which means that I can launch as many instances as I like!
thanks
K

#include <QtSingleApplication.h>
#include "mainwindow.h"
 
int main(int argc, char **argv)
{
	QtSingleApplication app("f76f6f66f66sa987g9866a", argc, argv);
 
	if (app.sendMessage("Do I exist?"))
		return 0;
 
	if(app.isRunning ())
		return 0;
 
	app.initialize();
 
	MainWindow w;
 
	QObject::connect(&app, SIGNAL(messageReceived(const QString&)),	
		&app, SLOT(activateMainWidget()));
 
	w.show();
 
	return app.exec();
}

#include <QtSingleApplication.h>
#include "mainwindow.h"

int main(int argc, char **argv)
{
	QtSingleApplication app("f76f6f66f66sa987g9866a", argc, argv);

	if (app.sendMessage("Do I exist?"))
		return 0;

	if(app.isRunning ())
		return 0;

	app.initialize();

	MainWindow w;

	QObject::connect(&app, SIGNAL(messageReceived(const QString&)),	
		&app, SLOT(activateMainWidget()));

	w.show();

	return app.exec();
}

Since the QSingleApplication class is a part of a commercial solution I would suggest that you contact the Trolltech helpdesk.
