Qt5 Tutorial Visual Studio Add-in - 2020

We need to download the following two:

1. Qt5 SDK , In my case, it's the Qt 5.1.1 for Windows 64-bit (VS 2012, OpenGL, 522 MB) (Info)
2. Visual Studio Add-in 1.2.2 for Qt5

Once the Add-in installed successfully, we should now see QT5 show up on the Menu Bar:

The next step is to let the VS know where to get bin/qmake and lib/libraries. Without this step, we may get "Unable to find a Qt build! To solve this problem specify a Qt build" when we try to create a new Qt5 project.

In my case, they are under "C:\Qt\Qt5.1.1\5.1.1\msvc2012_64_opengl".

So, we need to pass this information.

From the top menu, QT5->Qt Options. Then, select "Add" and type the path into "Path"

The "Version name" should be filled with 5.1.1. Hit OK.

Now, let's create a new Visual Studio Project: File -> New -> Project. We will now see a new addition called Qt5 Projects. This allows us to create various Qt applications. For now, select "Qt Application"

We just leave everything untouched.

Press "Finish"

Let's build the project and run.

We're going to add simple UI (QProgressBar and QSlider) with "valueChanged(int)" signal and "setValue(int)" slot.

Before we start building the project, we may want to make sure that our host and target are set properly.

Things to check - in my case, Host:x64, Target (Platform):x64

If this is not set properly, we may get "linking problem: fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86' or something similar error messages.

1. Check properties options in linker settings at: Properties > Configuration Properties > Linker > Advanced > Target Machine. In my case, it should be x64.
2. Select Build > Configuration Manager from the main menu in visual studio. Make sure our project has the correct platform specified.

After that, we should check Qt Project Settings as well. If this hasn't been set, we may get "There's no Qt version assigned to this project for platform x64" - visual studio plugin for Qt:

Right click the project > Qt Peoject Settings > Under the Properties tab > Version

Set signal and slot for the UI we added:

Build and run:

The progress bar keeps updated as we move the slider. So, seems to be working fine!
