Sending the command without the
row
parameter returns both lines of the display. The
$N
character
code is included to show where the top line ends and the bottom line begins. The
$N
character code
is returned even if
embellished
is set to
false
.
With
embellished
set to
true
, all other character codes that were used in the creation of each
message line are returned with the message. With
embellished
set to
false
, only the message
is returned.
Sending the command without the
columnStart
parameter defaults to column 1. Sending the
command without the
columnEnd
argument defaults to the last column (column 20 for row 1,
column 32 for row 2).
Input prompting
You can use display messaging with front panel controls to make a user script interactive. In an
interactive script, input prompts are displayed so that the operator can perform a prescribed action
using the front panel controls. While displaying an input prompt, the test pauses and waits for the
operator to perform the prescribed action.
Menu
You can present a user-defined menu on the display. The menu consists of the menu name on the
top line and a selectable list of menu items on the bottom line. To define a menu, use the
display.menu(
menu
,
items
)
function, where:
menu
The name of the menu; use a string of up to 20 characters (including spaces)
items
A string is made up of one or more menu items; each item must be separated by white space
When the
display.menu()
function is sent, script execution waits for the operator to select one of
the menu items. Rotate the navigation wheel to place the blinking cursor on a menu item. Items that
do not fit in the display area are displayed by rotating the navigation wheel to the right. With the
cursor on the menu item, press the navigation wheel (or the
ENTER
key) to select it.
Pressing the EXIT (LOCAL) key does not abort the script while the menu is displayed, but it returns
nil
. The script can be aborted by calling the
exit()
function when
nil
is returned.
The following programming example illustrates how to present the operator with the choice of two
menu items:
Test1
or
Test2
. If
Test1
is selected, the message
Running Test1
is displayed. If
Test2
is selected, the message
Running Test2
is displayed.
display.clear()
menu = display.menu("Sample Menu", "Test1 Test2")
if menu == "Test1" then
display.settext("Running Test1")
else
display.settext("Running Test2")
end
