The QGraphicsWebView class allows Web content to be added to a GraphicsView .
An instance of this class renders Web content from a URL or supplied as data, using features of the QtWebKit 模块。
If the width and height of the item are not set, they will default to 800 and 600, respectively. If the Web page contents is larger than that, scrollbars will be shown if not disabled explicitly.
Many of the functions, signals and properties provided by QWebView are also available for this item, making it simple to adapt existing code to use QGraphicsWebView instead of QWebView .
The item uses a QWebPage object to perform the rendering of Web content, and this can be obtained with the page () function, enabling the document itself to be accessed and modified.
As with QWebView , the item records the browsing history using a QWebHistory object, accessible using the history () 函数。 QWebSettings object that defines the configuration of the browser can be obtained with the settings () function, enabling features like plugin support to be customized for each item.
parent argument, if not None, causes self to be owned by Qt instead of PyQt.

查找指定字符串， subString , in the page, using the given options .
If the HighlightAllOccurrences flag is passed, the function will highlight all occurrences that exist in the page. All subsequent calls will extend the highlight, rather than replace it, with occurrences of the new string.
If the HighlightAllOccurrences flag is not passed, the function will select an occurrence and all subsequent calls will replace the current occurrence with the next one.
要清除选定，只需传递空字符串。
返回 true 若 subString was found; otherwise returns false.

Sets the content of the web graphicsitem to the specified content data 。若 mimeType argument is empty it is currently assumed that the content is HTML but in future versions we may introduce auto-detection.
External objects referenced in the content are located relative to baseUrl .
data is loaded immediately; external objects are loaded asynchronously.

重实现自 QGraphicsLayoutItem.setGeometry ().
将 Web 视图内容设为指定 html .
External objects such as stylesheets or images referenced in the HTML document are located relative to baseUrl .
html is loaded immediately; external objects are loaded asynchronously.
When using this method, WebKit assumes that external resources such as JavaScript programs or style sheets are encoded in UTF-8 unless otherwise specified. For example, the encoding of an external script can be specified through the charset attribute of the HTML script tag. Alternatively, the encoding can also be specified by the web server.
This is a convenience function equivalent to setContent(html, "text/html", baseUrl).
警告： This function works only for HTML, for other mime types (i.e. XHTML, SVG) setContent () should be used 代替。
