QT label(标签控件)的简单使用

#include "widget.h"
#include "ui_widget.h"
#include<QLabel>
#include<QPixmap>
#include<QMovie>
Widget::Widget(QWidget *parent)
    : QWidget(parent)
    , ui(new Ui::Widget)
{
    ui->setupUi(this);
    QPixmap pix;
    pix.load(":/image/b3.png");
    ui->label_2->setPixmap(pix);
    QMovie *mov=new QMovie(":/image/src=http___imgwcs3.soufunimg.com_news_2019_05_13_aca05def-a01d-4236-9241-a1b6aac07002.gif&refer=http___imgwcs3.soufunimg.gif");
    mov->setScaledSize(QSize(400,300));
    ui->label_3->setMovie(mov);
    connect(ui->pushButton,&QPushButton::clicked,[=](){
        mov->start();
    });
    connect(ui->pushButton_2,&QPushButton::clicked,[=](){
        mov->stop();
    });


}

Widget::~Widget()
{
    delete ui;
}
