• The Style property is as defined for general buttons.
• The Layout property is used to define where the optional label and data values
are to be placed relative to the button itself when custom images are used. The
text fields are always placed within the button for the other button styles.
• The Show Label property is used to indicate whether or not you want the
primitive to include a label to identify the data being displayed and controlled.
• The Show Data property is used to indicate whether or not the primitive should
include the associated data value. For buttons configured with a type of toggle or
momentary, the displayed data value is the value of the underlying tag. For other
buttons, the displayed value is the value to which the tag will be set.
• The Get From Tag properties are used to indicate from where the label text, the
field format and the text colors should be obtained. The options presented
depend on what was entered for the Value property. In each case, you may
manually enter the data in the appropriate properties, or, assuming a suitable
expression has been defined, you may instruct the primitive to get the required
information from the underlying data tag.
The second page defines additional formatting information, and is as described for the general
button primitive. The third page is used to define the custom images to be used to reflect the
button states, and is as described for the general button, except that different images can be
specified depending on whether the underlying tag is on or off. You should again refer to the
picture primitive for information on selecting images. The fourth page defines a number of
properties specific to data entry. These are as defined for the flag tag text primitive, and you
should refer to that section for details. The fifth and final page defines the label and format to
be used for the primitive, and is as defined for flag tags.

The Rich 2-State Selector primitive displays a rotary-style switch that can be used
to turn-on and turn-off a flag tag. As with all rich primitives, most of the
configuration data can be obtained from the underlying tag.
The Rich Multi-State Selector primitive displays a rotary-style switch that can be
used to turn on and turn off a multi tag. As with all rich primitives, most of the
configuration data can be obtained from the underlying tag.
Each of these primitives displays a circular selector switch within the area used to define the
primitive. If the primitive is tall enough that the circular switch has sufficient space above it,
labels can be added to the primitive to allow the various states to be identified.
