QWebEngineView 加载网页空白

Question

QWebEngineView 使用时，加载本地的html页面 出现白屏，并且QWebEngineView没有收到loadProgress 信号，在其他电脑没问题，html网页没有问题
代码如下；

#include <QApplication>
#include <QtWidgets>
#include <QTextBrowser>
#include <QtWebEngineWidgets>
#include <QGuiApplication>
#include <QDialog>
#include <QProcessEnvironment>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

     // 创建主窗口
    QDialog window;
    window.setWindowTitle("交易要素信息");
    window.setWindowFlags(Qt::WindowStaysOnTopHint | Qt::CustomizeWindowHint);

    // 设置窗口大小和位置
    int width = 64 * 12;
    int height = 42 * 12;
    QRect desktopRect = QGuiApplication::screens().at(0)->availableGeometry(); // 使用 QGuiApplication 获取屏幕几何形状
    window.setGeometry(desktopRect.width() - width, desktopRect.height() - height, width, height);

    // 加载本地 HTML 文件
    QString htmlFilePath = "index.html";
    QUrl url = QUrl::fromLocalFile(htmlFilePath);
    QWebEngineView view(&window);


    view.load(url);
    QObject::connect(&view, &QWebEngineView::loadProgress, [](int progress) {
        qDebug() << "Loading progress:" << progress;
    });

    QObject::connect(&view, &QWebEngineView::loadFinished, [](bool ok) {
        qDebug() << "Loading finished:" << ok;
    });
    // 将 QWebEngineView 添加到主窗口中
    QVBoxLayout layout(&window);
    layout.addWidget(&view);
    // 设置窗口固定大小
    window.setFixedSize(width, height);
    window.setWindowFlag(Qt::MSWindowsFixedSizeDialogHint);
    // 显示主窗口
    window.show();
     //window.close();
    return a.exec();
}

Answer 1

可能是因为本地 HTML 文件的路径不正确导致的。可以尝试使用绝对路径来加载 HTML 文件，或者检查相对路径是否正确。
