yes,I want to use multiple monitor in my program.

the next is my test code:

#include <QApplication>
#include <QDesktopWidget>
#include <QPushButton>
#include <QDebug>
int main(int argc, char **argv) {
QApplication app(argc, argv);
for (int i=0;i<app.desktop()->screenCount();i++) {
QWidget * dialog = new QWidget(app.desktop()->screen(i));
dialog->show();
qDebug() << app.desktop()->screen(i);
}
return app.exec();
}

the loop execute twice.
but I get the same pointer of app.desktop().screen(i)
