Qt QLabel标签添加点击事件

.h

1 //给label添加事件
2 bool eventFilter(QObject *obj, QEvent *event);

.cpp

 1 bool MainWindow::eventFilter(QObject *obj, QEvent *event){
 2     //mouse button pressed
 3     if (event->type() == QEvent::MouseButtonPress){
 4         QMouseEvent *mouseEvent = static_cast<QMouseEvent*>(event);
 5         if(mouseEvent->button() == Qt::LeftButton){
 6             if(obj == ui->label_avator){
 7                 qDebug()<<"在这里写点击事件";
 8                 return true;
 9             }else{
10                 return false;
11             }
12         }else{
13             return false;
14         }
15     }else{
16         return QObject::eventFilter(obj, event);
17     }
18 }

最后给QLabel添加事件过滤

ui->label_avator->installEventFilter(this);
