Qt/QML: WebView resizes really slowly when window resizing

Diego Donate

Hi,

I have a Qt application with QML and I need to display a webBrowser inside a QML file.

I have tried with Qml (using 'WebEngineView - QtWebEngine 1.1' or 'WebView - QtWebView 1.0') and in Qt (using 'QWebEngineView - Qt 5.6', with or without 'QWebEnginePage')

The HTML is loaded properly, but when I resize the window, the content (including the scroll bar) is resized slowly to the new window size, so it has a really bad effect.

My code is like that:

QML:


Item {
    id: rectChatView

    anchors.fill: parent
    ...
    WebEngineView  // or WebView
    {
        id: chatView
        anchors.fill: parent
        url: "file:///d:\\test.html"
    }
    ...
}

Qt

With QWebEngineView:

    QWebEngineView* pViewWeb = new QWebEngineView();
    pViewWeb->setWindowTitle("QWebEngineView");
    pViewWeb->load(QUrl("file:///d:\\test.html"));
    pViewWeb->setMinimumSize(300,300);
    pViewWeb->show();

or with QWebEnginePage:

    QWebEnginePage* pPage = new QWebEnginePage();
    pPage->load(QUrl("file:///d:\\test.html"));


    QWebEngineView* pView = new QWebEngineView();
    pView->setWindowTitle("QWebEngineView");
    pView->setMinimumSize(300,300);
    pView->setPage(pPage);
    pView->show();

But the 3 ways have the same result, too slow when resizing the window...

Any ideas? Thanks a lot in advance
