Û  Dialog boxes

    The dialog box is a special window
designed for the program to get information
from the user.  It is a convenient way to
view and set multiple options.

    When you are making settings in a
dialog box, you work with the following
basic GraphVision dialog controls: input-
line boxes, command buttons, list boxes,
check boxes and radio buttons.

    If you are using a mouse, click the
button, field or box you want.  When you
are using the keyboard, press <Alt> and
the underlined letter of an item to
activate it.  Press <Tab> to move among
Input-line and List boxes.


Û Input-line box

    You type input text into an Input-line
box.  Most basic text-editing keys work in
the Input-line box.  If you continue to
type once you reach the end of the box, the
contents automatically scroll.  When you
move to an empty Input-line box, an edit
cursor (flashing underscore "_") appears .
The text you type starts at this cursor
point.  If the box you move to already
contains text, this text is selected, and
any text you type replaces it.


Û  Command button

    Choose a Command button to initiate an
action immediately, such as carrying out or
canceling a command.


Û  List box

    A list box displays a list of choices.
It contains a vertical scroll bar that lets
you scroll through and select from
variable-length lists (often names) without
leaving a dialog box.  You can use a mouse
to make a selection, or use the arrow keys
to move between list items and press
<Space Bar> to select an item.

Û  Check box

    Check boxes are used to get multiple
choices from user.  You can select as many
check box options as needed.  When a check
box is selected, it contains an X.  To
select a check box, click the box or select
the group you want and use the arrow keys
to choose a particular check box, then press
<Space Bar> to select it.

Û  Radio buttons

    Radio buttons represent mutually
exclusive choices.  For this reason, radio
buttons always come in groups, and you can
select only one option at a time.  The
selected radio button contains a black dot.
To select a radio button, click the button
or select the group you want and use the
arrow keys to choose a particular radio
button.
