About spectrum bindings
This binding animated a widget's brush (color) property by mapping a numeric value into a color range defined by lowColor,
midColor, and highColor properties
Figure 343. Spectrum Binding properties
| Property | Value | Description |
|---|---|---|
| Ord | Chooser; defaults to null |
Defines the location of the data value to bind to the widget. This is a required property for the widget to be bound. |
| Degrade Behavior | Chooser; defaults to null |
Specifies how the interface displays invalid options. For example, if a user does not have permission to invoke a specific action, a button bound to that action can be grayed out or hidden entirely. |
| Widget Property | drop-down list | Specifies the target property in the binding’s parent widget. For example, if the spectrum binding has a bound label parent, this property can change the background or foreground property of the parent label. You can target only one property in the parent widget per binding. To target more than one, add additional bindings. |
| Low Color | chooser | Specifies the color for the lowest-value assignment. When the bound target value is less than the setpoint minus extent divided
by two (2), it displays in this color. As the value bound to this property increases above the minimum value specified, the
color changes, approaching the color set by the Mid Color property.
|
| Mid Color | chooser | Specifies the color for the mid-range value. When the bound value is exactly at the setpoint, it displays in this color. As
it increases above this point, the color changes, approaching the color set by the High Color property. As the value decreases below the setpoint, the color changes, approaching the color set by the Low Color property.
|
| High Color | chooser | Specifies the color for the highest value assignment. When the bound target is greater than the setpoint plus extent divided
by two (2), it displays in this color. As the bound value decreases below the maximum value specified, the color changes,
approaching the color set by the Mid Color property.
|
| Setpoint | number to one decimal | Specifies the mid-color value. For example, when set to 70, the value displays using the color you defined for Mid Color when it reaches 70.
|
| Extent | number to one decimal | Represents the total range of the bound value, which maps from low to high. |
