You can use a macro to change the look and feel of a session. You can also programmatically change display elements such as the screen color, font, and cursor. Some examples of changing these elements include:

• Changing the background color to indicate which program is being used, highlight specific types of information, or indicate a data type (such as the type of dataset).
• Changing the font size to adjust to changes in screen resolution.  
• Toggling the rule line on or off. 

This sample shows how to load a theme and change the cursor, font, and background color of the session.

To run this sample

1. In a terminal session, open the Visual Basic Editor and insert a module in the session project folder.
2. Copy the code into the module code window and then press F5 to run the macro.

   Change colors, fonts, and cursor

Concepts

The Theme object contains the ThemeFont, ThemeColor, and ThemeCursor objects. You get access to these objects through the Theme object. 

Another approach for changing theme properties is to load an entire theme:

'Load a theme

ThisIbmTerminal.Theme.Load (Environ$("USERPROFILE") & "\Documents\Micro Focus\Reflection\Themes\myTheme.themex")

'Load a theme

    ThisTerminal.Theme.Load (Environ$("USERPROFILE") & "\Documents\Micro Focus\Reflection\Themes\myTheme.themex")

You can run these macros automatically when certain screens are recognized or when specific events occur. For example, after a user selects a program, you could indicate which program is running by changing the background color on the first screen of the program.
