## Properties

Components are the equivalent of C++ classes. In standard C++ terminology, a class defines data members for each object by specifying a name and type for each of the associated data elements. In the UI Designer, every object of a component class exposes the properties of that object.

The Properties view provides a convenient interface to edit the values for each property of a component object. The Property Editor determines the name and type for each property by parsing the associated component definition files. It uses that information to provide editors for each property. The editors for each property ensure that you may enter only values that are appropriate for them.

The toolset provides component definition files for standard components. You must create component definition files to support your custom components.
