Qt codecompletion etc. without a project.

[mrandreas]

Is it possible to get qt code completion in qt creator without working in a project.

1. Open qt-creator.
2. drag a cpp file into the editor.
3. req.1 - Verify that you have F1 (help) for all Qxxx
4. req.2 - Verify that you have completion for all Qxxx

As far as I remember code works based on files included by the current file so all you have to do is to add #include statements to your code.

It doesn't work for me. I don't get Qt code completion, but in some cases i get completion between files i drag in and are listed in "Open Documents". Are there a setting or syntax I'm missing?

Are the include files from Qt underlined with green and when you hover over them Creator says it can't find the respective file?

The green classes and namespaces has code completion (etc). The Qxxx (Qt classes) however is not green. I have only made it work when I reference the qt include path in a projectname.includes. The code files I'm working on is always on a mapped drive. The path to the qt path is somthing like L:/thirdParty/qt/winxp_vc/release/include/. I'm using another building system.

I just noticed that when I check in the file in clearcase (verson control program) the code complition disappear and the green text is gone...

I don't mean the font color but rather the wavy line under the text.

It seems I'm right then. The problem is that Qt includes are usually not in the default place for include files in your system so Creator can't find them without pointing it to them. When you use qmake (or some other project management tool), it adds appropriate directories to the search path so that the files can be found. If you use another build tool, you should mimic the same behaviour. Unfortunately you have to do it in Creator compliant way - either by generating a Makefile and pointing Creator to it or by writing a plugin for Creator to handle your custom build tool.

You need at least a dummy project to have a "file collection". You can create one easily using "qmake -project", and you do not have to use this dummy project for building (just remove the build steps in the build settings)
