如何在不打开窗口的情况下使用QWebEngineView拍摄网页截图 [英] How to take webpage screenshots using QWebEngineView without opening window

问题描述

我正在寻找一种使用QWebEngineView拍摄网站截图的方法.主要目标是开发在后台运行的无头屏幕捕获应用程序.

我设法获得了一个最小的工作示例(请参见此).但是，这些示例要求通过调用QWebEngineView::show()，QWebEngineView::showMinimized()或什至QWebEngineView::setVisible(true)来使QWebEngineView小部件可见，以便能够截取网站的屏幕截图.由于这会导致打开一系列窗口，因此该解决方案并不完美.

有没有人知道使用QWebEngineView来截取网站屏幕快照而不打开窗口的方法?

解决方案

解决方案非常简单:通过调用QWidget::setAttribute(Qt::WA_DontShowOnScreen)设置Qt::WA_DontShowOnScreen属性，将QWebEngineView小部件配置为不显示在屏幕上.

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?

解决方案

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).
