Customizing an aplet
You can customize an aplet and develop a set of
programs to work with the aplet.
Use the SETVIEWS command to create a custom VIEWS
menu which links specially written programs to the new
aplet.
A useful method for customizing an aplet is illustrated
below:
1. Decide on the built-in aplet that you want to
customize. For example you could customize the
Function aplet or the Statistics aplet. The customized
aplet inherits all the properties of the built-in aplet.
Save the customized aplet with a unique name.
2. Customize the new aplet if you need to, for example
by presetting axes or angle measures.
3. Develop the programs to work with your customized
aplet. When you develop the aplet’s programs, use
the standard aplet naming convention. This allows
you to keep track of the programs in the Program
catalog that belong to each aplet. See “Aplet naming
convention” on page 18-10.
