wxString str = "Hello World!"; str.Clear();
wxString str; str << "The answer is: " << 42; str.Clear();This code creates an empty wxString object 'str' and appends the text "The answer is: " and the number 42 to it using the << operator. Then it clears the content of the string using the Clear function. These examples demonstrate how the Clear function can be used to reset the content of a wxString object. This function is defined in the wxString header file, which is part of the wxWidgets core library.
