@class wxTextInputStream
@wxheader{txtstrm.h}
- This class provides functions that read text datas using an input stream.
- So, you can read @e text floats, integers.
-
- The wxTextInputStream correctly reads text files (or streams) in DOS, Macintosh
- and Unix formats and reports a single newline char as a line ending.
-
- Operator is overloaded and you can use this class like a standard C++ iostream.
- Note, however, that the arguments are the fixed size types wxUint32, wxInt32 etc
- and on a typical 32-bit computer, none of these match to the "long" type
- (wxInt32
- is defined as int on 32-bit architectures) so that you cannot use long. To avoid
- problems (here and elsewhere), make use of wxInt32, wxUint32 and similar types.
-
- If you're scanning through a file using wxTextInputStream, you should check for
- EOF @b before
- reading the next item (word / number), because otherwise the last item may get
- lost.
- You should however be prepared to receive an empty item (empty string / zero
- number) at the
- end of file, especially on Windows systems. This is unavoidable because most
- (but not all) files end
- with whitespace (i.e. usually a newline).
