Thanks for the help
The call for the dialog is make by this
class ShowResults;
if (!showResults){
showResults = new ShowResults (this, "showResutls");
connect(this, SIGNAL(newData(QString)),
showResults, SLOT(newData(QString)));
}
showResults->show();
showResults->raise();
showResults->setActiveWindow();
filename = workingFileName ;
emit newData(workingFileName);
This the header file
#ifndef FINDDIALOG_H
#define FINDDIALOG_H
#include <qdialog.h>
class QCheckBox;
class QLabel;
class QLineEdit;
class QPushButton;
