Wow, I absolutely did not see this coming – finally the Trolls^WNokians offer a lean and nice cross-platform IDE for Qt which incorporates all other Qt tools and a gdb frontend! Formerly dubbed “Project Greenhouse” the baby just got a new name and fancy logo: Qt Creator. There is a pre-release version available for download, licensed under a special preview license. The final product should be dual-licensed though, like the rest of the Qt tools are.
Oh what a happy day for Qt users (ever wanted to look at the value of a QString in gdb…?) and what a sad one for all the other free Qt IDEs out there, like edyuk or QDevelop. Especially edyuk looked very promising since it provided a lot of features and a good user interface.
