Several methods of QT setting loading interface

Preface

Introduce two methods of setting the loading interface

Static picture display

    QSplashScreen splash(QPixmap(":/rec/lancoo7.png"));
    splash.setDisabled(true);// The input event of the hexadecimal user corresponds 
    splash.show();
    delayMSec(2000);        // Nonblocking delay 2s, Simulate complex programs 
    splash.close();

delaydelayMSec Functions encapsulate methods for themselves

void MainWindow::delayMSec(unsigned int msec)
{
    
    QTime Time_set = QTime::currentTime().addMSecs(msec);
    while( QTime::currentTime() < Time_set )
        QCoreApplication::processEvents(QEventLoop::AllEvents, 100);
}

gif Picture shows

    QPixmap pixmap(":/rec/gif2.gif");
    QMovie movie(":/rec/gif2.gif");
    QLabel label;
    label.setMovie(&movie);
    movie.start();
    label.setFixedSize(400,400);
    movie.setScaledSize(label.size());
    label.move(QApplication::desktop()->width()/2-label.width()/2,QApplication::desktop()->height()/2-label.height()/2);		// If there's a mistake here , Then add #include <QDesktopWidget> The header file 
    label.setWindowFlags(Qt::FramelessWindowHint);// Hide borders 
    label.setWindowModality(Qt::ApplicationModal); // Block all forms except the current form 
    label.show();
    delayMSec(2000);        // Nonblocking delay 2s, Simulate complex programs 
    movie.stop();
    label.close();
