qwebpage

问题 I'm using Qt's QWebPage to render a page that uses javascript to update its content dynamically - so a library that just downloads a static version of the page (such as urllib2) won't work. My problem is, when I render a second page, about 99% of the time the program just crashes. At other times, it will work three times before crashing. I've also gotten a few segfaults, but it is all very random. My guess is the object I'm using to render isn't getting deleted properly, so trying to reuse it

问题 Having a DOM of the following html; <a href="?op=order"> <img class="img_button" src="picture.gif" onMouseOver="this.src='some.gif';" onMouseOut="this.src='some_other.gif';" alt="" border="0"> </a> how to follow a link (href) in QWebKit (specifically QWebPage). Please notice that it's an image that is linked. I can't do it (and I don't want to even if I could) by simulating a mouse click as I don't use QWebView thus I don't have the page rendered. 回答1: Assuming you have the link's QWebElement

问题 I have been unable to find a definitive answer to my problem. I currently have a QWebView control load an html file that is on my hard-drive, that implements a vector map with javascript actions. The html file loads a jvectormap US States Map. The click action on any state fires the onRegionClick action that is tied to the showCities function, which the event and code arguments are handled by the onRegionClick method implemented in the jquery-jvectormap.js file. The html file follows: <

问题 I use QWebPage to download a webpage as well as all its resources. At the same time I'd like to get hold on raw data being downloaded by Qt during this process. Doing this by reading data from QNetworkReply in void QNetworkAccessManager::finished(QNetworkReply * reply) signal is not a good solution as data could have been already read by QWebPage itself. This is because QNetworkReply is a sequential-access QIODevice, which means that once data is read from the object, it no longer kept by the

问题 This is driving me crazy. I want to show in a QWebPage an url, but i want to do it passing by an anonimous proxy. Code #setting up the proxy proxy = QNetworkProxy() proxy.setHostName("189.75.98.199") #just examples proxy.setPort(1111) proxy.setType = QNetworkProxy.HttpProxy #setting the manager manager = QNetworkAccessManager() manager.setProxy(proxy) #setting the proxy on the manager #setting the proxy as application proxy QNetworkProxy.setApplicationProxy(proxy) #seems to do nothing.. #web

问题 I'm loading content into QWebPage, using load() method. But my loadStarted(), loadFinished() and loadProgress() handlers are calling several times.
