matlab.system.display.Header Class

Namespace: matlab.system.display

Specify header in Block Parameters dialog box for MATLAB System block

Description

Use the matlab.system.display.Header class to specify the content of the header in the Block Parameters dialog box for a MATLAB System (Simulink) block. The header includes a title and descriptive text. You can also include a link to the code that defines the System object™ for the block.

Create an instance of this class within the getHeaderImpl method for the block.

Creation

Description

h = matlab.system.display.Header creates an instance of the Header class.

h = matlab.system.display.Header(Name,Value) creates an instance of the Header class with property values defined using one or more name-value arguments.

h = matlab.system.display.Header(sysObj) creates an instance of the Header class and configures the properties based on the System object sysObj.

h = matlab.system.display.Header(sysObj,Name,Value) creates an instance of the Header class and configures properties based on the System object sysObj and one or more name-value arguments. The name-value arguments you specify override the property values that come from the System object.

Input Arguments

sysObj — System object for MATLAB System block

System object

System object for MATLAB System block, specified as a System object. When you specify a System object as the input for the Header class constructor, the instance created by the constructor has properties set based on the System object.

• Title — System object name

• Text — Help summary for System object

• ShowSourceLink — true unless the System object code is P-coded so that the source code is not available

You can specify this argument as mfilename('class').

Properties

Title — Title for header in Block Parameters dialog box

'' (default) | string | character vector

Title for header in Block Parameters dialog box, specified as a string or a character vector. By default, the title is an empty character vector ('').

Example: 'AlternativeTitle'

Attributes:

GetAccess	public
SetAccess	public

Data Types: string | char

Text — Descriptive text to display below title in Block Parameters dialog box

'' (default) | string | character vector

Descriptive text to display below title in Block Parameters dialog box, specified as a string or a character vector. By default, the text is an empty character vector ('').

Example: 'An alternative class description'

Attributes:

GetAccess	public
SetAccess	public

Data Types: string | char

ShowSourceLink — Option to show link to source code in Block Parameters dialog box

'true' | 'false'

Option to show link to source code in Block Parameters dialog box, specified as 'true' or 'false'.

Attributes:

GetAccess	public
SetAccess	public

Data Types: string | char

Examples

Define Header for MATLAB System Block Parameters Dialog Box

Define a header in your class definition file.

 methods (Static, Access = protected)
    function header = getHeaderImpl
       header = matlab.system.display.Header(mfilename('class'), ...
           'Title','AlternativeTitle',...
           'Text','An alternative class description');
    end
 end

The header appears above the Parameters section in the Block Parameters dialog box. This example creates a header that includes a link to the source code.
