问题
I'm looking for a way to take website screenshots with QWebEngineView. The main goal is to develop a headless screencapture application that runs in the background.
I've managed to get a minimal working example to work (see this for example). However, these examples require that the QWebEngineView widget is made visible, either with calls to QWebEngineView::show(), QWebEngineView::showMinimized() or even QWebEngineView::setVisible(true), to be able to take a screen capture of a website. As this results in opening a series of windows, this solution is less than perfect.
Does anyone know of a way to use QWebEngineView to take screenshots of websites without having windows popping open?
回答1:
The solution is rather easy: configure the QWebEngineView widget to not show onscreen by setting the Qt::WA_DontShowOnScreen attribute through a call to QWidget::setAttribute(Qt::WA_DontShowOnScreen).
