CCWrapper test applet

[Mikael Hermansson <mikeh bahnhof se>]

I trying to write an Gtk applet in C++
doing this will not work memory corruption.
when callback calls DestroyObject() it sigsegv
looks like pointer has been overwritten somewhere...

class MainWindow
{
		bool bDestroy=false;
		GtkWidget *window;
	public:
		MainWindow(gchar *title);
		~MainWindow();

		gint DestroyObject();
		void MainLoop();
		GtkWidget * GetWidget(){	return 	window;};
};
void cb_destroy(GtkWidget *w,MainWindow *mptr)
{
	if(mptr->DestroyObject) /* In this example it should return false */
		delete mptr; /*so the object will not destroy in callback
*/
	/* main will doit when MainLoop returns */
}
MainWindow::MainWindow(gchar *title)
{
	bDestroy=false;
	window=gtk_window_new();
	gtk_window_title(GTK_WINDOW(window),title);

	gtk_signal_connect(GTK_OBJECT(window),"delete_event",GTK_SIGNAL_FUNC(cb_destroy),this);
}
MainWindow::~MainWindow()
{
}
void MainWindow::MainLoop
{
	bDestroy=false;	/* Make sure object will not destroy in callback*/
	gtk_main();
}	
gint MainWindow::ObjectDestroy()
{
	gtk_main_quit();
	return bDestroy;	
}
main(int c,char *arg)
{
	MainWindow *ptr=NULL;
	
	gtk_init(&c,&arg);

	ptr=new MainWindow("Craptest");
	ptr->MainLoop();
	delete ptr;
}
