    File:       Sample.h

    Contains:   Sample is an example application that demonstrates how to

                initialize the commonly used toolbox managers, operate 

                successfully under MultiFinder, handle desk accessories, 

                and create, grow, and zoom windows.

                It does not by any means demonstrate all the techniques 

                you need for a large application. In particular, Sample 

                does not cover exception handling, multiple windows/documents, 

                sophisticated memory management, printing, or undo. All of 

                these are vital parts of a normal full-sized application.

                This application is an example of the form of a Macintosh 

                application; it is NOT a template. It is NOT intended to be 

                used as a foundation for the next world-class, best-selling, 

                600K application. A stick figure drawing of the human body may 

                be a good example of the form for a painting, but that does not 

                mean it should be used as the basis for the next Mona Lisa.

                We recommend that you review this program or TESample before 

                beginning a new application.

/*  Determining an application's minimum size to request from MultiFinder depends

    on many things, each of which can be unique to an application's function,

    the anticipated environment, the developer's attitude of what constitutes

    reasonable functionality and performance, etc. Here is a list of some things to

    consider when determining the minimum size (and preferred size) for your

    application. The list is pretty much in order of importance, but by no means

    complete.

    1.  What is the minimum size needed to give almost 100 percent assurance

        that the application won't crash because it ran out of memory? This

        includes not only things that you do have direct control over such as

        checking for NIL handles and pointers, but also things that some

        feel are not so much under their control such as QuickDraw and the

        Segment Loader.

    2.  What kind of performance can a user expect from the application when

        it is running in the minimum memory configuration? Performance includes

        not only speed in handling data, but also things like how many documents

        can be opened, etc.

    3.  What are the typical sizes of scraps [is a boy dog] that a user might

        wish to work with when lauching or switching to your application? If

        the amount of memory is too small, the scrap may get lost [will have

        to be shot]. This can be quite frustrating to the user.

    4.  The previous items have concentrated on topics that tend to cause an

        increase in the minimum size to request from MultiFinder. On the flip

        side, however, should be the consideration of what environments the

        application may be running in. There may be a high probability that

        many users with relatively small memory configurations will want to

        avail themselves of your application. Or, many users might want to use it

        while several other, possibly related/complementary applications are

        running. If that is the case, it would be helpful to have a fairly

        small minimum size.

    So, what did we decide on Sample? First, Sample has little risk of

    running out of memory once it starts. Second, performance isn't much

    of an issue since it doesn't do much and multiple windows are not

    allowed. Third, there are no edit operations in Sample itself, so we

    just want to provide enough space for a reasonable scrap to survive

    between desk accessory launches. Lastly, Sample should intrude as little

    as possible, so the effort should be towards making it as small as possible.

    We looked at some heap dumps while the application was running under

    various partition sizes. With a size of 23K, there was approximately

    8-9K free, which is a good 'slop' factor in an application like this

    which doesn't do much, but where we'd still like the scrap to survive

    most of the time. */
