詳細描述

WebView is a component for displaying web content which is implemented using native APIs on the platforms where this is available, thus it does not necessarily require including a full web browser stack as part of the application.

To make the Qt WebView module function correctly across all platforms, it is necessary to call QtWebView::initialize () right after creating the QGuiApplication 實例。

注意： Due to platform limitations overlapping the WebView and other QML components is not supported.
