|
*
|
|
* January 9, 1995 1.01A : The spinner class was modified so that it
|
|
* could be used in a DOS DLL. This mostly
|
|
* meant adding those far definitions to the
|
|
* member function prototypes. It also meant
|
|
* creation of ALSpinner::new().

/*
|
|
* class ALSpinner : public ALMonitor
|
|
*
|
|
* DESCRIPTION
|
|
*
|
|
* ALSpinner is a very simple monitor class, and is only useful under
|
|
* DOS, not Windows. All ALSpinner does is spin a little propellor
|
|
* around while the file is being processed. This lets you know
|
|
* that something is happening in an otherwise boring process.
|
|
*
|
|
* DATA MEMBERS
|
|
*
|
|
* miSpinIndex : A Static variable that keeps track of which
|
|
* position the propellor should be in. The
|
|
* propellor travels through one of four different
|
|
* positions.
|
|
*
|
|
* mrStream : A reference to the stream that the propellor is
|
|
* going to be written on.
|
|
*
|
|
* MEMBER FUNCTIONS
|
|
*
|
|
* ALSpinner() : The one and only constructor.
|
|
* ~ALSpinner() : The virtual destructor.
|
|
* Progress() : The routine that gets called to make the
|
|
* propellor twitch.
|
|
* ArchiveOperation() : The routine that gets called when archiving
|
|
* starts, stops, etc.

* Microsoft refuses to define cout if you are building a

|

* anyone from using the bargraph class from a DLL. That's
|
|
* okay anyway, since Microsoft doesn't have a 16 bit
|
|
* DLL RTL.
