DESKTOP is a clone of the MS-DOS Executive program
which comes with Microsoft Windows (TM of Microsoft
Corporation). This version does not attempt to recreate
every feature of the Windows version, nor is it
guaranteed to be bug-free. DESKTOP was written to
demonstrate the capabilities of our MEWEL window
library, and to show how similar a MEWEL application
can look to a Windows, Presentation Manager, or Mac
application.

You can pull down a menu by pressing the ALT key along
with the menu item's highlighted letter. You can select
an item from the pulldown menu by pressing the item's
highlighted letter, or you may use the cursor to move
to the desired selection and press ENTER. Pressing ESC
will exit from the menu without invoking any actions.

You can invoke the system menu (represented by the lit-
tle box in the upper left corner) by pressing
ALT+SPACE. The only entry which is active on the system
menu is the CLOSE entry.

You can navigate through the directory listing by using
the cursor keys. Pressing ENTER on a directory name
will change the current directory. Pressing ENTER on an
executable program will run that program.

Pressing CTRL and a drive letter will change the cur-
rent drive.

You can exit the program quickly by pressing ALT+X.

The DESKTOP program (and all MEWEL applications) sup-
port the mouse fully.

You can select a file by positioning the mouse over the
file and clicking the left button.

You can change directories by positioning the mouse
over a directory name and double clicking.

You can run a program by positioning the mouse over
a program name and double clicking.

You can change directories quickly by positioning the
mouse over the current path name (located to the right
of the disk drive icons) and clicking the left button.
The component of the path name which is to the left of
the mouse click will be used as the name of the direc-
tory to change to.

You can change the current drive by clicking on the
appropriate drive icon.

The Calculator is a sample application which can run
under the desktop. It is implemented as a "modeless"
dialog box, which means that other windows and menus
are active while the calculator is running.

You can use the mouse to click on any of the buttons
on the calculator, or you can press the key which
corresponds to the label on the button. The 'N' key
will invoke the ñ button, the 'S' key will invoke the
û function, and pressing the M key and the R, C, +,
or '-' key will invoke one of the memory functions.

To exit from the calculator, click the 'Q' button or
press the 'Q' key.

If you click on the directory window while the
calculator is visible, the calculator will be hidden.
To make the calculator visible again, select the
Applications menubar item and select the Calculator
item.

MEWEL stands for Magma Extensible Window and Event
Library. It is the first text-mode windowing library to
use the message-passing model like other state of the
art windowing systems such as MS-Windows, PM, X WIndows
and the MacIntosh. MEWEL supports all of the modern
controls, like dialog boxes, edit fields, scrollbars,
radio buttons, check boxes, push buttons, and
listboxes. Full mouse support is included. The API and
messages are fairly compatible with version 2.1 of
Microsoft Windows. When version 3.0 of Windows is
released, MEWEL will support its API.
