Debugging

Visual Studio supports debugging Qt C++ applications using the Visual Studio debugger and Qt Quick applications using the QML debug engine. To debug applications on Linux, you can use GDB.

You can debug Qt and Qt Quick applications in Visual Studio by setting breakpoints in C++ and QML files and stepping through the execution of code. While in break mode, you can watch variables and change their values, as well as evaluate arbitrary expressions. For Qt Quick applications, a QML debugging session runs concurrently to a C++ debugging session, which enables you to set breakpoints and watch variables in both C++ and QML during the same debugging session.

To start a debugging session, select Debug > Start Debugging or press F5.
