pyqt4 - Set QWebView to mobile dimensions -

-

i trying crawl pages on site mobile user. set user agent match iphone, , trying set dimensions match 320x568. after that, want take screenshot can see pages like, , make sure correct. however, it's desktop view. how can set qwebview or qwebpage mobile dimensions when load specific page?

below self.qweb qwebview. saw this question using qmainwindow, headless crawl, , works great is, except setting width & height of "browser" view. tried variations of it, waiting page load, , resetting size, it's not working.

if hasattr(self, 'height') , hasattr(self, 'width'):     size = self.qweb.page().mainframe().contentssize()     self.qweb.resize(320, 568)  self.qweb.setpage(self.page()) self.qweb.loadfinished.connect(self.loaded_page)

update tried well, after page loaded, qsize returned 980x568. tried same function calls in loaded_page method after page loads, didn't work either. resets view larger size when action on page performed.

    self.qweb.setpage(self.page())     self.qweb.page().setviewportsize(qtcore.qsize(320, 568))     self.qweb.page().setpreferredcontentssize(qtcore.qsize(320, 568))     self.qweb.loadfinished.connect(self.loaded_page)  def loaded_page(self):     # returns qsize(980,568)     size = self.qweb.page().mainframe().contentssize()

this page setup

class page(qwebpage):     """qwebpage implementation custom user agent string"""      def __init__(self):         qwebpage.__init__(self)          # settings         s = self.settings()         s.setattribute(qwebsettings.autoloadimages, true)         s.setattribute(qwebsettings.javascriptcanopenwindows, true)         s.setattribute(qwebsettings.pluginsenabled, true)

it sounds need set preferred contents size:

    page.setpreferredcontentssize(qtcore.qsize(320, 568))

but if doesn't give right results, try setting viewport size:

    page.setviewportsize(qtcore.qsize(320, 568))
