iname - The internal name of the object, constituting a dot-separated list of identifiers, corresponding to the position of the object's representation in the view.

value - An object of type gdb.Value representing the value to be displayed.

If None is passed as name, a serial number is used. The object's internal name is created by concatenating parentiname and iname.

_init_(self, value, parentiname, iname, name = None) - A constructor.

The Item Python class is a thin wrapper around values corresponding to one line in the Locals and Expressions view. The function has to feed the Dumper object with certain information which is used to build up the object and its children's display in the Locals and Expressions view. The function is passed the following parameters: The debugger plugin calls this function whenever you want to display an object of this type. The function name has to be qdump_NS_Foo, where NS::Foo is the class or class template to be examined. > Debugger > GDB and specify a filename in the GDB startup script field. To use another file, select Tools > Options. By default, the following startup file is used: ~/.gdbinit. To extend the shipped Python based debugging helpers for custom types, define one Python function per user defined type in the GDB startup file. It is also easier to extend as the script is less dependent on the actual Qt version and does not need compilation. This is more robust as the script execution is separated from the debugged process. On platforms featuring a Python-enabled version of the GDB debugger, the data extraction is done by a Python script.

So information can be displayed nicely only in a limited fashion by using a cdb extension DLL.Įxtending the Python Based Debugging Helpers There is no GDB to communicate with MSVC compiled applications on Windows.Therefore, extracting QObject properties, for example, is not possible. On the Symbian platform, an on-device debugging agent restricts the communication between GDB and the device.

Mac OS continues injection with C++ based debugging helpers.

There is no Python-enabled GDB for Mac OS.

Python scripting vastly reduces the communication overhead compared with the previous solution. No compilation is required, just adding a few lines of Python. You can now easily extend the debugging helpers to other types.

The code injection caused problems and put an extra stress on the debugged process. When Python scripting is used, code (Debugging helpers) does not need to be injected into the debugged process to nicely display QStringList or std::map contents, for example. Qt Creator uses GDB builds that enable Python scripting to display information in the Locals and Expressions view. As the internal data structures of Qt can change between versions, the debugging helper library is built for each Qt version. To create your own debugging helper library, select Tools > Options. The Qt SDK package already contains a prebuilt debugging helper library. Moreover, this approach will automatically be chosen as fallback in case the Python based approach fails.ĭuring debugging with the C++ based debugging helpers, Qt Creator dynamically loads a helper library in form of a DLL or a shared object into the debugged process. While it has been superseded on most platforms by the more robust and more flexible second approch using Python scripting, it is the only feasible one on Windows/MSVC, Mac OS, and old Linux distributions. This is the first and original approach to display complex data types. Using the debugging helpers is not essential for debugging with Qt Creator, but they enhance the user's ability to quickly examine complex data significantly. For this purpose, it takes advantage of two technologies, collectively referred to as Debugging Helpers.

Qt Creator is able to show complex data types in a customized, user-extensible manner.
