How to set the size of browser using QtWebKit

由 爷，独闯天下 提交于 2019-12-03 08:41:42
Recently I use PyQt4 to crawl some web pages. I want to set different size of the browser which is generated by QWebView().show() . I tried to use the following code snippet to set the size: self.qsize = QWebPage().viewportSize() self.qsize.setHeight(3000) self.qsize.setWidth(1000) print self.qsize.height() print self.qsize.width() But the browser displayed is always the same size. Please give me some tips on how to set the size of the browser displayed by QWebView . Thanks in advance. I tested this, the window resizes itself after loadFinished is emitted: import sys from PySide.QtCore import

I have never used Qt and WebKit and now have a need to create a simple single web page browser using the Qt WebKit module . The application that I'm looking to create needs to have a plain window that displays a web page URL passed in via command line. I've done this sort of thing using WebKitGTK but I have no idea where to start in Qt . I've done some research to see what is involved and so far I've only been able to find snippets of code that pertain to the WebKit QWebView class. So can anybody provide me with complete sample code that will just display a web page in Qt ? Once I get that

Does PhantomJS use QtWebKit or Blink?

由 早过忘川 提交于 2019-12-02 10:16:17
问题 Does PhantomJS (CasperJS) use WebKit or Chromium as default browser-driver? If WebKit, is it direct WebKit or qt or gtk? 回答1: PhantomJS is based on QtWebKit. The FAQ says: Q: Which WebKit version is used by PhantomJS? A: If you want to know HTML5/CSS3/other features supported by PhantomJS, using WebKit version is not a good idea. See Supported Web Standards documentation page for details. If you really like to get the WebKit version, find it via the user agent, run the examples/useragent.js.
