Objective

Change the order and number of properties displayed for an object of your class.

Change the Property Order

Suppose your class definition contains the following property definition:

properties

Name

JobTitle

Department

Salary

Password

end

In the default scalar object display, MATLAB displays all the public properties along with

their values. However, you want to display only Department, JobTitle, and Name, in

that order. You can do this by deriving from CustomDisplay and overriding the

getPropertyGroups method.

Your override

• Defines method Access as protected to match the definition in the CustomDisplay
  superclass


• Creates a cell array of property names in the desired order


• Returns a PropertyGroup object constructed from the property list cell array

methods (Access = protected)

function propgrp = getPropertyGroups(~)

proplist = {'Department','JobTitle','Name'};

propgrp = matlab.mixin.util.PropertyGroup(proplist);
