I am happy to push them upstream. My first move was to add this progress bar example I had put on the wiki. I checked out Qt from gitorious and looked in examples/qtconcurrent/ and there was a progressdialog example that does exactly what mine did! In this case, I would have really loved a link to it from here:
http://developer.qt.nokia.com/doc/qt-4.8/qtconcurrent.html
and a few other places (http://developer.qt.nokia.com/doc/qt-4.8/qfuturewatcher.html for example).
I looked in qfuturewatcher.cpp and saw a 'snippet' command, but we should not include the full example inline with the documentation, but rather simply link to it. I would suggest something like an "Examples" section that would appear in the "Contents" menu on the documentation page. Any thoughts on a good way to do this? Also, most examples will have many more than one file. It would be ideal to be able to display them all one one page (like this: http://programmingexamples.net/wiki/Qt/ModelView/ListViewComboBox ).
Lets continue with this examples/qtconcurrent/progressdialog example as a test case. Once we develop a system, I'll start working on submitting new examples.
