The following screenshot shows what you will see when you launch Qt Creator for the first time. Let's take a closer look at each portion of the screen, shown as follows:
The main window, which currently shows the buttons for New Project and Open Project, is your workspace. The workspace also includes links to the Qt projects, examples, and tutorials as well as Qt's developer documentation, such as its online community and blogs. Under normal conditions, this will be located where you'll see the source code for your application. Along the left-hand side of the screen are a series of icons that let you select various views in your application. They are as follows:
The Welcome mode, which shows basic information about Qt Creator
The Edit mode, which lets you edit the files that make up your application
The Design mode, which lets you use Qt Designer to design the user interface for your application
The Debug mode, which lets you debug your application while it's running, including doing things such as viewing the memory and variables, setting breakpoints, and stepping through the application
The Projects mode, which lets you adjust the build and link settings for your project
The Analyze mode, which lets you profile your application's runtime performance
The Help mode, which provides documentation on Qt Creator and the Qt framework
