#HELP
#HELPKEYS
You may scroll with the Cursor Up/Down Keys.
You may leave the help with the Function Key labelled 'Quit'.
#INHELP
You are already in the help system.
You may leave the help with the Function Key labelled 'Quit'.
#MAIN
This is the main menu of the sample program for the ncurses Ada95
binding. The main intention of the demo is not to demonstate or
test all the features of ncurses and it's subsystems, but to provide
to you some sample code how to use the binding with Ada95. 

You may select this options:

   * Look at some ncurses core functions
   * Look at some features of the menu subsystem
   * Look at some features of the form subsystem
   * Look at the output of the Ada.Text_IO like functions
     for ncurses.
   
#MAINPAD
You may press at any place in this demo CTRL-C. This will give you a command
window. You can just type in the Label-String of a function key, then this
key will be simulated. This should help you to run the application even if
you run it on a terminal with no or only a few function keys. With CTRL-N
and CTRL-P you may browse through the possible values in the command window.
#MENU00
Here we give you a selection of various menu demonstrations.
#MENU-PAD00
This menu itself is a demo for a single valued, 1-column menu with
descriptions for the items, a marker and a padding character between
the item name and the description.
#MENU01
This is a demo of the some of the menu layout options. One of them
is the spacing functionality. Just press the Key labelled "Flip" to 
flip between the non-spaced and a spaced version of the menu. Please
note that this functionality is unique for ncurses and is not found 
in the SVr4 menu implementation. 

This is a menu that sometimes doesn't fit into it's window and 
therefore it becomes a scroll menu. 

You can also see here very nicely the pattern matching functionality
of menus. Type for example a 'J' and you will be positioned to the
next item after the current starting with a 'J'. Any more characters
you type in make the pattern more specific. With CTRL-A and CTRL-Z
(for more details press the Key labelled "Keys") you can browse
through all the items matching the pattern.

You may change the format of the menu. Just press one of the keys
labelled "4x1", "4x2" or "4x3" to get a menu with that many rows
and columns.

With the Keys "O-Row" or "O-Col" (they occupy the same label and
switch on selection) you can change the major order scheme for 
the menu. If "O-Col" is visible, the menu is currently major
ordered by rows, you can switch to major column order by pressing
the key. If "O-Row" is visible, it's just the reverse situation.
This Key is not visible in "4x1" layout mode, because in this case
the functionality makes no sense.

With the Keys "Multi" or "Singl" (they occupy the same label and
switch on selection) you can change whether or not the menu allows
multiple or only single selection.

With the Keys "+Desc" or "-Desc" (they occupy the same label and
switch on selection) you can change whether or not the descriptions
for each item should be displayed. Please not that this key is
not visible in the "4x3" layout mode, because in this case the
menu wouldn't fit on a typicall 80x24 screen.

With the Keys "Disab" or "Enab" (they occupy the same label and
switch on selection) you can dis- or enable the selectability of
the month with 31 days.
#MENU-PAD01
You may press "Flip" to see the effect of ncurses unique menu-spacing.
The Keys "4x1", "4x2" and "4x3" will change the format of the menu.
Please note that this is a scrolling menu. You may also play with the
pattern matching functionality or try to change the format of the menu.
For more details press the Key labelled "Help".
#FORM00
This is a demo of the forms package.
#FORM-PAD00
Please note that this demo is far from being complete. It really shows
only a small part of the functionality of the forms package. Let's hope 
the next version will have a richer demo (You wan't to contribute ?).
#NOTIMPL
Sorry this functionality of the demo is not implemented at the moment.
Remember this is a freeware project, so I can use only my very rare
free time to continue coding. If you would like to contribute, you
are very welcome !
#CURSES00
This is a menu where you can select some different demos of the ncurses
functionality.
#CURSES-PAD00
Please note that this demo is far from being complete. It really shows
only a small part of the functionality of the curses package. Let's hope 
the next version will have a richer demo (You wan't to contribute ?).
#MOUSEKEYS
In this demo you may use this keys:

   - Key labelled "Help"  to get a help
   - Key labelled "Keys"  is what you are reading now
   - Key labelled "Quit"  to leave the demo

You may click the mouse buttons at any location at the screen and look
at the protocol window !
#MOUSE00
A rather simple use of a mouse as demo. It's there just to test the
code and to provide the sample source. 

It might be of interest, that the output into the protocol window is
done by the (n)curses Text_IO subpackages. Especially the output of
the button and state names is done by Ads's enumeration IO, which 
allows you to print the names of enumeration literals. That's really
nice.
#MOUSE-PAD00
This is a very simple demo of the mouse features of ncurses. It's there
just to test whether or not the generated code for the binding really
works on the different architectures (seems so).
#ATTRIBDEMO
Again this is a more than simple demo and just here to give you the
sourcecode.
#ATTRIBKEYS
You may press one of the three well known standard keys of this demo.
#ATTRIB-PAD00
Again this is a more than simple demo and just here to give you the
sourcecode. Feel free to contribute more.
#TEXTIO
#TEXTIOKEYS
#TEXTIO-PAD00
