QWebEngineView - HTML Font Size

narayanan.krish

Hello,

Can someone clarify If I can increase the font size of a html content (text) inside QWebEngineView. I've tried updating the QWebEngineSettings *defaultSetting's font sizes but in vain.

Thanks & Regards,
Nara

hi,

You can set a minimum size with QWebEngineSettings
or apply a zoom factor to your webview.

There is a very similar question here:

Thanks for the reply. I've already followed that link and tried the following. I'm not seeing any changes for both zoom factor or font size. Is there anything I could miss ?

From the debug messages, I'm able to observe that the values are updated, but I'm not able to observe any changes in the view.

QWebEngineSettings *defaultSettings = QWebEngineSettings::globalSettings();
    qDebug() << "default fontsssssssssssss"
             << defaultSettings->fontSize(QWebEngineSettings::MinimumFontSize)
             << defaultSettings->fontSize((QWebEngineSettings::MinimumLogicalFontSize))
             << defaultSettings->fontSize(QWebEngineSettings::DefaultFontSize)
             << defaultSettings->fontSize(QWebEngineSettings::DefaultFixedFontSize)
             << m_adSlipsWebView->zoomFactor();

    m_adSlipsWebView->setZoomFactor(5);

    defaultSettings->setFontSize(QWebEngineSettings::MinimumFontSize,50);
    defaultSettings->setFontSize(QWebEngineSettings::MinimumLogicalFontSize,50);
    defaultSettings->setFontSize(QWebEngineSettings::DefaultFontSize,50);
    defaultSettings->setFontSize(QWebEngineSettings::DefaultFixedFontSize,50);

    QFontDatabase fontDataBase;
    QFont standardFont=fontDataBase.font("Arial","",24);
    defaultSettings->setFontFamily(QWebEngineSettings::StandardFont, standardFont.family());

I've tried above options before calliing

m_adSlipsWebView->setHtml(m_config.clientConfig->adSlipsContent());

Thanks & Regards,
