I am wondering that no-one mentioned that HiQt becomes the best IDE for Qt4.
I tried HiQt 0.1.17 for windows with all my present projects an found it much more stable and (or)easier to work with than all the other IDE 's for Qt. Even it 's still beta.
HiQt writes nothing to your consisting Pro-file, is simple and efficient.
After download, I unzipped the package to a folder, dragged my pro-file on the HiQt.exe and could immediately continue my work in a preferred way.
I would be very interested in your comments and experiences concerning HiQt.
