After downloads are completed it will start installing.
Qt Creator will launch and show the Welcome screen. Qt Creator should auto-detect the Qt install and compiler and create a "kit" for desktop development. We can now test the installation by creating a simple project.
Pick the kit only one option is available then Next. You can specify some more information.
Pick the defaults unless you want to use something else. Pick no project management.
You will now see the created skeleton application. You can look at the source code if desired: a main. Click the hammer icon at lower left to build it. You can click on Compiler Output if you want to see it. The project should successfully build. You can now click on the green triangle icon to run it.

Getting Started With Qt and Qt Creator on Windows
Build and run it as before. If the above steps worked you are all set up to develop with Qt on the desktop.
You can now create your own applications from scratch or start with one of the many examples or tutorials available within Qt Creator. This lab will also introduce you to some of the tools necessary for editing a UI using Qt Creator.
This lab will walk you step-by-step through the building process. Things you need to do will be highlighted in yellow, and we will do our best to go 1 This lab is based on M arcio Buenos tutorial Tutorial de OpenGL com Qt Creator, available online at: 2.
For this course, we only care about building desktop applications, but feel free to play around with other platforms if youre curious. For this project, check the box marked: Desktop.
