This section explains how a Library Widget can be linked to a specific Model
component
Each Library Widget can be linked to a specific (Schematic) Model component. In this way,
a Library widget can be specialized to work only with particular components (for example
customizing a Library Widget to control and monitor Machines).
To link a Library Widget to a Model Component, the Library Widget must
first be created and saved to the Widget Library, and then it can be linked.
Detailed information on creating a Library Widget can be found
here.
When creating a Library Widget, you can specify the types of
Model components that can be linked with this Library Widget (for example all supported
Machine types). Model component types can be specified in the Link to Model
Component tab in the Library Widget properties dialog (Figure 1).Figure 1. Model component types
Note: Component types can be easily obtained from Schematic Editor by right clicking on a
Schematic component and selecting the Copy component information → Copy component
type name action.
Note: When a Library Widget is already linked to a particular Model component, a few constants are injected into the Library Widget's local namespace (Figure 1). Specifically, this occurs every time a simulation is started,
or the Library Widget is copy/cut/pasted, is dragged and dropped, or when the namespace manually initialized. At the same time when the constants are injected,
the Library Widget Initialization code is executed.
When you drag and drop a Library Widget into a Panel, you should specify the particular
Model component from the supported types (for example, a particular Machine), that needs to
be linked with the Library Widget (Figure 2).
This can also be set in the Library Widget properties dialog after the widget is added
to the Panel (Figure 3).
Note: Components from supported types will only be listed if it exists
in the loaded Model (*.cpd file)

Once a Model component is selected, the Library Widget is successfully linked to the
particular Model component.
