Exporting a Visual Studio Project to a Qt Project

With the Visual Studio Qt plugin installed (can be downloaded from here ), simply:

• Open your solution.

• Select any Qt based project from your solution (or any file in that project).

• Go to the menu Qt5 > Create basic .pro File...
  
  .

• Select the projects you want to export.

• Run qmake
  
  or open it from Qt Creator.

PS: depending on your VS and Qt versions, you may need an older version of the plugin. I am assuming Qt 5 is here.

Hope it helps.
