\title Specifying Dynamic Properties
You can bind object properties to dynamic expressions to define global
properties for an object that can be read by other objects. For example,
you can specify global properties for the root object that you can use in
the child objects.
In addition to the properties predefined for QML types, you can specify
\e {dynamic properties} to add properties that would not otherwise
exist for a particular type. You bind the properties to dynamic expressions
to define global properties for an object that can be read by other objects.
For example, you can specify global properties for the root object that you
can use in the child objects.
For example, to specify spacing between UI elements, you could define a
margin for an object of a QML type that does not have a margin property,
and then use bindings to refer to the value of the margin property from
other objects.
Similarly, you can add dynamic properties at component level.
You can specify dynamic properties for objects in the
\uicontrol Connections view.
