MATLAB Creating Graphical User Interfaces

• Click on the Properties tab in the Code Browser, expand the drop-down list on the
  button, and select Private Property or Public Property.

After you select an option to create a property, App Designer adds a property definition

and a comment to a properties block.

properties (Access = public)

Property % Description

end

The properties block is editable, so you can change the name of the property and edit

the comment to describe the property. For example, this property stores a value for

average cost:

properties (Access = public)

X % Average cost

end

If your code needs to access a property value when the app starts, you can initialize its

value in the properties block or in the StartupFcn callback.

properties (Access = public)

X = 5; % Average cost

end

Elsewhere in your code, use dot notation to get or set the value of a property:

y = app.X % Get the value of X

app.X = 5; % Set the value of X
