add Qt to existing Visual Studio c++ project [closed]

Question

I've got an existing Visual Studio C++ project. It creates a main window using GLUT and also uses glut for a right-click context menu.

All I want to do now, is to open a second window used as a property inspector to display and change some values.

Everyone recommends using Qt for GUI development, but all the tutorials I find discuss either working in Qt creator or how to create a Qt project from scratch.

I have used Qt some years ago to do something similar and it was not so difficult to add it to my project.

Can anyone explain, or point me to a tutorial explaining how to do this?

thanks!

Answer 1

Thank to Arno Duvenhage and Tom for their answers. Here are steps who worked for me in Qt 5.2.1 and Visual Studio 2012 and 2015:

1. Install QT Add In (for visual studio 2015 is in still in beta, but works fully for me).

2. Right click the project, select "Unload project".

3. Add add the <keyword>Qt4VSv1.0</keyword> entry into the <PropertyGroup Label="Globals"> tag.

4. Select load project.

5. Select "Convert project to Qt Add-in project" in "Qt 5" menu.

6. Almost done. Go to Qt project settings and Qt option in the Qt menu to set details.

7. In your project properties Linker\Additional Library Directories\ might need to add $(QTDIR)\lib

8. In your project properties C++\Additional Include Directories\ might need to add $(QTDIR)\include

9. In each of your classes derived from Q_OBJECT, delete the Q_OBJECT macro, save the file, return the Q_OBJECT macro (Ctrl+Z), and save again. It adds the 'moc' files to your generated files folder.

10. Set your project as startup project.

Answer 2

edit your project using an xml editor
i usually unload the project, right click on it and select edit

add the qt version you wish to use (for me it's):

Keyword="Qt4VSv1.0"

and the following globals

        <Global
        Name="lupdateOnBuild"
        Value="0"
    />
    <Global
        Name="MocDir"
        Value=".\GeneratedFiles\$(ConfigurationName)"
    />
    <Global
        Name="MocOptions"
        Value=""
    />
    <Global
        Name="QtVersion Win32"
        Value="QT 4.5.3"
    />
    <Global
        Name="RccDir"
        Value=".\GeneratedFiles"
    />
    <Global
        Name="UicDir"
        Value=".\GeneratedFiles"
    />

reload the project and fiddle with "convert project to QMake generated project" and it should work

Answer 3

This works for me:

• manually change the project version to a qt project in the project file -- use <Keyword>Qt4VSv1.0</Keyword>'
• reload the project
• right click on the project and select 'update to a qt-addin project'
• remove and add the qt source files to the project

Hope it helps.
