问题 I use the following code in a QWebEngineView object to capture a web page to an image: image=new QImage(w,h, QImage::Format_ARGB32); painter = new QPainter(image); render(painter); image->save(imagefilename); Unfortunately, it only renders part of the web page that is shown on the widget to the image. How to render the whole page to the image? 回答1: It is possible to hide webview and resize it to show the whole web page. I'm using PyQt5 (version 5.12), but the idea should apply to C++ Qt as

问题 I'm trying to get the screenshot of a given URL as a bitmap image on the Windows Phone. The WebBrowser class does not seem to have the DrawToBitmap method.
