Modelica.Blocks.Types

Information

In this package types and constants are defined that are used in library Modelica.Blocks. The types have additional annotation choices definitions that define the menus to be built up in the graphical user interface when the type is used as parameter in a declaration.

Extends from Modelica.Icons.Package (Icon for standard packages).
