Quick User Interfaces with Qt

The user interface is progressing quickly these days. It has been 15 years since cool 3-D buttons and the like, as popularized by Windows 95 and other early windowing environments, emerged. Now, we see halo effects, shades, transparency and more—all hardware-accelerated, and all making our computers look better than ever.
The Future

Looking at the future of Qt Quick, many things may happen. In MeeGo, the MeeGo touch initiative is implementing new widgets using Qt Quick. In KDE, Plasma is supporting Qt Quick. One effect of this is that you can write Plasmoids using QML. In the Qt tooling department, the trolls are working on a visual designer for Qt Quick. It already has a few interesting features—for instance, layers can be imported from GIMP and Photoshop directly into the designer.

Looking at Qt, I don't think we have seen the last widget-based application yet. Actually, when creating serious software for serious tasks, I see no reason not to use widgets. However, with the new focus on mobile, not only within the old Trolltech, but the entire Linux community, I think that Qt Quick will be a very frequently used tool.
