C++ (Cpp) refreshMonitor Examples

Example #1

File: abstractmonitor.cpp Project: mcfrisk/kdenlive

void VideoSurface::paintEvent(QPaintEvent *event)
{
    Q_UNUSED(event);
    //WARNING: This might trigger unnecessary refreshes from MLT's producer, but without this,
    // as soon as monitor is covered by a popup menu or another window, image is corrupted.
    emit refreshMonitor();
}

Example #2

File: mainwindow.cpp Project: Mr-Phoebe/ProgramDesign

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    room[1] = "房间1";
    room[2] = "房间2";
    room[3] = "房间3";
    room[4] = "房间4";
    room[5] = "房间5";

    //根据状态信息给room1~room5赋值，我这里是特别简单的直接赋值 看一下可读状态信息赋值后分别显示

    ui->textBrowser_room1->setText(room[1]+"\n\n关机");//显示文本一内容，可设置参数为房间状态文本,
    ui->textBrowser_room2->setText(room[2]+"\n\n关机");
    ui->textBrowser_room3->setText(room[3]+"\n\n关机");
    ui->textBrowser_room4->setText(room[4]+"\n\n关机");
    ui->textBrowser_room5->setText(room[5]+"\n\n关机");


    setupsocket();
    port = 6666;

    //新建一个QTimer对象
    timer = new QTimer();
    //设置定时器每个多少毫秒发送一个timeout()信号
    timer->setInterval(60000/quick);
    //启动定时器
    timer->start();
    //信号和槽
    connect(timer, SIGNAL(timeout()), this, SLOT(refreshMonitor()));
