The style now comes in two flavors: Standard, and Office. The standard style is the one seen previously. The new Office style is presented here:

I also have some good news for commercial users waiting for this. The style will be renamed QtDotNetStyle and should be released as a dual licensed Qt Solution, hopefully next week.

Some of you might remember my blog post about this back in October. Now that 4.3.0 is out, I finally had time to clean up the sources and release something usable on labs.

The style is a close approximation to the appearance of Visual Studio 2005, Office 2003 as well as the .NET based application framework. It will give your application a modern gradient appearance for tool bars and menus while retaining the native look and feel for other widgets.
A solution for commercial customers will probably be made available in the near future based on feedback I get on this.
Not too long ago, someone asked why we did not support dot net style in Qt. Although the name is a bit misleading, it means the look and feel that apps such as Office and Outlook currently use. These applications are like Qt based on the windows style engine, but for some of the components that the theme does not define they use a more fashionable gradient appearance.
To prove that Qt can actually support these styles, I wrote a plugin style for Qt 4.2. If there is sufficient interest we will of course consider making it available as a solution or even as a part of a future version of Qt.
Here is some eye candy:

And this is how it looks with the blue palette:
