Why I can't see the code from The Qt Assistant or qt-project.org/doc

Hi chenjie4255, Your browser is ok, but the documentation is broken. It is being fixed now, and you should be able to see the code when Qt 5.1 comes out. For now, you can find the code for that example in <Qt>\examples\quick\tutorials\samegame <Qt> depends on the package you downloaded. For example, the VS 2012 package could be C:\Qt\5.0.2-msvc2012-x64\5.0.2\msvc2012_64\examples\quick\tutorials\samegame
