qtwebkit

问题 I am currently building an application that makes use of QML WebView ( import QtWebKit 3.0 ). The users need to resize the WebView very often (I am using a QML SplitView ), however this leads to the UI to lag extremely whenever the app window is resized.

QWebPage *webpage = ... webpage->settings()->setAttribute(QWebSettings::PluginsEnabled, true); Plugins are loaded by NPAPI

I have used onmousedown="return false" in the body tag but it disables mouse clicking and this would affect all of my input fields since the user will not be able to get the focus on input

问题 I have a Qt 4.6 based application which use QtWebView to load a HTML page with tag inside to play a network multimedia source on Windows platform. Instead of using the default PHONON playback engine i build another PHONON back-end engine to handle the media download, demuxer,decoder, rendering etc. It works pretty well.

问题 Currently I have my HTML, JS, CSS, graphics, etc stored locally on hard disk and access them using QWebFrame::SetUrl( QUrl::fromLocalFile( "appFolder\html\index.html" )) . At some point I am going to need to encrypt the locally stored files so I'm looking for a way to either decrypt them as they're requested or to decrypt them all into memory and access them that way. I know I can use QWebFrame::setContent( htmlData ) to load the HTML from memory so I can load the encrypted HTML file, decrypt
