Hi! See this wiki article: Clickable QLabel.

Another solution could be using event filter

//MyClass.h
QLabel *clickablelabel

//MyClass.cpp
MyClass::MyClass(QObject *parent) {
//...
clickablelabel = new QLabel("Click Me!");

clickablelabel->installEventFilter(this);
//...
}
bool MyClass::eventFilter(QObject *o, QEvent *e) {

if(o == clickablelabel && e->type() == QMouseEvent::MouseButtonPress) {
//do something
}
/* //using metaObject() thingies 
if(e->type() == QMouseEvent::MouseButtonPress && o->metaObject()->className() == (new QLabel)->metaObject()->className()) {
//do something
}
*/
return QObject::eventFilter(o,e);
}

Two other options:

If it's clickable why not use a button? You can make it flat if you don't want the usual button bevel.

You can put an html link in the label and it will emit a linkActivated signal when you click on it.

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
QLabel *dispimg= new QLabel(this);
dispimg->setStyleSheet("image:url(E:/may/may_7/images/singdisp.png);");
dispimg->setGeometry(330,190,200,200);
connect(this, SIGNAL( clicked() ), this, SLOT( slotClicked() ) );

}

MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::mousePressEvent ( QMouseEvent * event )
{
emit clicked();
}

void MainWindow::slotClicked()
{
qDebug()<<"hello";
}
