About value bindings
These bindings bind to values that are typically under a component. Value bindings support features such as real-time graphics,
mouse-over, and right-click actions.
This pop-up opens when you right-click an object on a PX grid.
| 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 | drop-down list; defaults to None |
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. |
| Hyperlink | Chooser; defaults to null |
Links to another object. When used, the link is active in the browser or in the graphic view. |
| Summary | Chooser; defaults to %displayName%=%.% | Specifies a display name for the widget as text or by means of a script. |
| Popup Enabled | true (default) or false |
Specifies if a secondary window is to open when a user clicks this label in a browser or the graphic view. |
Types of Converters
Converters are part of the system’s logic features. They change data from one type to another; for example, a statusBoolean to a statusNumeric so that a process, which outputs an inactive value, becomes a numeric value (1) in the next process. In most cases, when you animate a property, the correct data converter appears, by default, at the top of the list.
Figure 356. Types of converters
The following types of converters are available when using a value binding:
- I Boolean To Simple converts a number data type link (to-double, to-float, to-long, to-integer) resulting in a 0 value for a Boolean false, or 1 if a Boolean true.
- I Boolean To Boolean has a
False Valueconverter property with a default value of 0. The default 0 keeps the statusBoolean value in synch with the source Boolean value. IfFalse Valueis set to 1, the linked statusBoolean value is opposite (NOT) the source. - I Enum to Simple converts an enumerated value to a simple value.
- I Enum to Enum converts one enumerated value to the same type of value.
