\title Adding Bindings Between Properties
To dynamically change the behavior of an object, you can create a \e binding
between the properties of two objects. To create a property binding, a
property is assigned a JavaScript expression that evaluates to the desired
value. At its simplest, a binding may be a reference to another property.
For example, the height of an object can be bound to the height of its
parent, so that when the parent height changes, the object height is
adjusted automatically.
For more information about the use of property bindings, see
\l{Property Binding}.
You can create bindings between objects in the \uicontrol Connections view.

To bind a property of an object to the property of another object:
\list 1
\li In the \uicontrol {Connections} view, select the
\uicontrol {Bindings} tab.
\li Select the \inlineimage plus.png
(\uicontrol Add) button to add a binding for the currently selected
item. The ID is displayed in the \uicontrol Item column.
\li Double-click the value in the \uicontrol Property column to select
the property to bind to a source property.
\li Double-click the value in the \uicontrol {Source Item} column to
select the object whose property you want to use to determine the
behavior of the target object.
\li Double-click the value in the \uicontrol {Source Property} column
to select the property to bind the target property to.
