The following link has a gallery for useful Qt creator plugins.
But unfortunately, I don't know how to install any of them. For example, how to install artistic code style plugin?
Does Qt creator has a plugin manager like Eclipse that facilitates adding plugins through it?
You can find instructions for installation at the bottom of the webpage of Artistic Code Style plugin:
Move the downloaded zip/tar.bz2 archive to the root directory of Qt Creator and extract it. After a restart of Qt Creator all should work.
Looks like plugins can be found under
.\QtCreator\lib\qtcreator\plugins so if you want to install a plugin you just need to copy the files of the plugin (one
dll and one
pluginspec) there and (re)start Qt Creator.
