LLQtWebKit

Introduction

LLQtWebKit is a static library that renders Web content into a memory buffer using code from a modified version of the Qt application and UI framework. It is currently used by the most recent version of the Media Plugin API to render Web content in the Second Life viewer.

License

LLQtWebKit is released under the GPL V2 license.

Build instructions

Windows

The Windows version of the build instructions can be found here.

Mac OSX

The Mac OSX version of the build instructions can be found here.

Linux

The Linux version of the build instructions (in the form of a README file) can be found here.

However, that README-linux.txt is incorrect. Since Qt 4, qmake has the Qt location hardcoded and ignores QTDIR. It is necessary to run the correct qmake (and uic) and therefore to make sure that the correct ones are found *first* in the PATH. Also, some webpages instruct one that you must set QMAKESPEC to $QTDIR/mkspecs/default.

Hence, correct instructions are (change '4.6.0' as appropriate for your Qt version):

export QTDIR=/usr/local/Trolltech/Qt-4.6.0
export PATH=$QTDIR/bin:$PATH
export QMAKESPEC=$QTDIR/mkspecs/default

And then continue as instructed (which qmake and which uic now should show a binary in your QTDIR).

Test applications

As well as the source code and other files required to build LLQtWebKit, there are a number of applications included in the package that are useful for testing. You can browse the code here. Details of how to build them are included in the platform specific build instructions above.

qttestapp - A simple Qt based, cross platform application that implements a simple Web browser
win32gl - A simple Win32 specific application that implements a simple Web browser
testgl - A simple GLUT based, cross platform application that implements a simple Web browser
ubrowser - A more complex application GLUT/GLUI based, cross platform application that renders multiple Web pages on the surface of 3D geometry

Version numbers

The version of Qt/WebKit used is: 4.6.0

Previous Incarnations

LLMozLib2 - the initial version of a Web content rendering library for Second Life that used the Mozilla/Gecko rendering engine. This is now deprecated.

Qt WebKit - a poorly named version of the Web content rendering engine for Second Life that uses Qt/WebKit to render but retained the same method/class names from LLMozLib2. This is now deprecated.
