wxString myString = wxT("Hello world!"); string stdString = myString.ToStdString();
wxString myString = "This is a test string"; cout << myString.ToStdString() << endl;In this example, we create a wxString object called `myString` and assign it the value "This is a test string". We then call the ToStdString method on this object and print the resulting string to the console using `cout`. The package library for the wxString class is the wxWidgets library. This library provides a set of C++ classes that allow developers to create native applications that can run on multiple platforms, such as Windows, macOS, and Linux. The wxString class is one of the many classes provided by the wxWidgets library.
