9.2 Widget Programming
The type and location of elements shown on the 920i
display are easily specified using the drag and drop
features of the
iRev 4 utility. However, display widgets
can also be programmed using serial commands while

programming. Up to ten different screens can be
configured.

accomplished in setup mode, using the WDGT serial
command. The first parameter specified is the widget
type, listed in Table 9-18. The following sections
describe each of the widget types and the parameters
and values specific to that type.
In setup mode, the WDGT.CLR serial command can
be used to clear all specified widgets from the display.
Table 9-18. Widget Types
Type Description
1 Scale Widget
2 Bitmap Widget
3 Bargraph Widget
4 Label Widget
5 Numeric Widget
6 Symbol Widget
Some widget types require that the location or size of
the widget be specified, in pixels. Figure 9-18 shows
the pixel counts (80 pixels per inch) used to specify
the pixel location on the display.

Setting the data_source of bargraph, label, numeric,
and symbol widgets to 2 (program) allows these
widget types to be directly controlled by an
iRite
program rather than by indicator data. The user
program must provide the code necessary for widget
manipulation.
9.2.1 Scale Widgets
Scale widgets are used to present basic scale data from
one or more configured scales. For multiple scale
applications, up to four scale widgets c an be
configured to be shown on the display at any one time.
Fewer displayed widgets allow each widget to be
larger. Scale data from additional configured scales
can be shown by scrolling up or down through all
configured scales, including a total scale widget, if
configured.
WDGT#n=1, scale_widget_size, scales_displayed,
screen_number
where:
n=widget number
1= scale widget type
scale_widget_size = 1–6 (size refers to numeral height)
1: 1/4 "
2: 1/2"
3: 3/4"
4: 7/8 "
5: 1"
6: 1 5/32 "
scales_displayed = 1–4
screen_number = 1–10
Example:
WDGT#1=1,2,1,2<CR>
creates a single 1/2" scale widget for screen number 2.
9.2.2 Bitmap Widgets
Bitmap widgets provide a representation of vertical or
horizontal tanks or a hopper. The location, size, and
border style of the widget are specified on the WDGT
command.
WDGT#n=2, left, top, width, height,border_style,
bitmap_widget_style, name/alias, visible,
screen_number
where:
n=widget number
2= bitmap widget type
left = left edge location, in pixels
top = top edge location, in pixels
width = width, in pixels
height = height, in pixels
border_style = 1 (none)
bitmap_widget_style = 1 (vertical tank), 2 (horizontal
tank), 3 (hopper)
name/alias = text name or alias
visible = 1 (on) or 2 (off)
screen_number = 1–10
Example:
WDGT#2=2,30,30,120,120,1,3,Hopper1,1,2<CR>
