static const char IN_Master[]    = "\tWelcome to the MUI demonstration program. \
This little toy will show you how easy it is to create graphical user interfaces \
with MUI and how powerful the results are.\n\tMUI is based on BOOPSI, Amiga's \
basic object oriented programming system. For details about programming, see the \
'ReadMe' file and the documented source code of this demo. Only one thing so far: \
it's really easy!\n\tNow go on, click around and watch this demo. Or use your \
keyboard (TAB, Return, Cursor-Keys) if you like that better. Hint: play \
around with the MUI preferences program and customize every pixel to fit \
your personal taste.";

static const char IN_Notify[]    = "\tMUI objects communicate with each other \
with the aid of a notifcation system. This system is frequently used in every \
MUI application. Binding an up and a down arrow to a prop gadget e.g. makes up \
a scrollbar, binding a scrollbar to a list makes up a listview. You can also \
bind windows to buttons, thus the window will be opened when the button is \
pressed.\n\tRemember: The main loop of this demo program simply consists of \
a Wait(). Once set up, MUI handles all user actions concerning the GUI \
automatically.";

static const char IN_Frames[]    = "\tEvery MUI object can have a surrounding \
frame. Several types are available, all adjustable with the preferences program.";

static const char IN_Images[]    = "\tMUI offers a vector image class, that allows \
images to be zoomed to any dimension. Every MUI image is transformed to match the \
current screens colors before displaying.\n\tThere are several standard images for \
often used GUI components (e.g. Arrows). These standard images can be defined via \
the preferences program.";

static const char IN_Groups[]    = "\tGroups are very important for MUI. Their \
combinations determine how the GUI will look. A group may contain any number of \
child objects, which are positioned either horizontal or vertical.\n\tWhen a \
group is layouted, the available space is distributed between all of its \
children, depending on their minimum and maximum dimensions and on their \
weight.\n\tOf course, the children of a group may be other groups. There \
are no restrictions.";

static const char IN_Backfill[]  = "\tEvery object can have its own background, \
if it wants to. MUI offers several standard backgrounds (e.g. one of the DrawInfo \
pens or one of the rasters below).\nThe prefs program allows defining a large number \
of backgrounds... try it!";

static const char IN_Listviews[] = "\tMUI's list class is very flexible. A list can \
be made up of any number of columns containing formatted text or even images. Several \
subclasses of list class (e.g. a directory class and a volume class) are available. \
All MUI lists have the capability of multi selection, just by setting a single \
flag.\n\tThe small info texts at the top of each demo window are made with floattext \
class. This one just needs a character string as input and formats the text according \
to its width.";

static const char IN_Cycle[]     = "\tCycle gadgets, radios buttons and simple lists \
can be used to let the user pick exactly one selection from a list of choices. In this \
example, all three possibilities are shown. Of course they are connected via notification, \
so every object will immediately be notified and updated when necessary.";

for text input. The gadget in this example is attached to the list, you can control the \
list cursor from within the gadget.";
