Retrieves the contents of local variables.

Retrieves data representing the call stack at the program's current position.

The program is automatically interrupted when a breakpoint is hit. You can interrupt a running C++ program by selecting Debug > Interrupt. Once the program starts running under the control of the debugger, it behaves and performs as usual. To show and hide columns in views, toggle Show Column in the context menu. To save space on the screen, select View > Views > Automatically Hide View Titlebars.

Select View > Views > Reset to Default Layout to reset the views to their original sizes and positions. The size and position of views are saved for future sessions. You can drag and drop the views in Qt Creator to new positions on the screen. Alternatively, you can enable or disable views from the context menu of the title bar of any visible debugger view. To change the default settings, select View > Views, and then select views to display or hide. Frequently used views are shown by default and rarely used ones are hidden. The availability of views depends on whether you are debugging C++ or QML. In Debug mode, you can use several views to interact with the program you are debugging. This deeper understanding is used to present objects of such classes in a useful way.

The debugger plugin understands the internal layout of several Qt classes, for example, QString, the Qt containers, and most importantly QObject (and classes derived from it), as well as most containers of the C++ Standard Library and some GCC extensions. In addition to the generic IDE functionality provided by stack view, views for locals and expressions, registers, and so on, Qt Creator includes features to make debugging Qt-based applications easy. Qt Creator displays the raw information provided by the native debuggers in a clear and concise manner with the goal to simplify the debugging process as much as possible without losing the power of the native debuggers.

You can interact with the debugger in several ways, including the following: You can use the Qt Creator Debug mode to inspect the state of your application while debugging.
