Trying to integrate qmake into Visual Studio or Xcode can be a real pain in the ass. Instead, it’s really not that hard to write a python script to update your moc, ui, and rcc files, since all qmake does is generate makefiles that do a simple date check for each file. Hack and destroy the following code to your liking, and add it as a build step in your favorite IDE:

(Ah yes, and this code tends to run faster than make will!)

This is the basics behind the algorithm, which also runs for UIC and MOC files.
