Since the weekend is here I downloaded QtCreator IDE and sources for Qt library itself. Download took under just 1 hour on my 512 kbps connection and compiling the library also took just under 1 hour on my quad core desktop

First wrote a simple Qt dialog app with a progress bar with buttons to increase/decrease the progress using the Qt library I downloaded.

Then I modified the Qt library qprogressbar.cpp file to try to add "smooth effects" well simple/crude step-scrolling - yet to add real motion dynamics (im totally useless at physics/math here so will take me time - or i can steal code online).

Captured the videos with recordmydesktop package (you can see the code in the left side heh) which youtube accepts the .ogv files. The QtCreator IDE is pretty slick if a little unstable/slow... is fun working with it

edit: of course you need to add " -j 4 " to the call to "make" if you want to use all 4 cores so "make -j 4" when building code generally.
