In the coming description of the components of a model, you'll see that every possible property is assigned a default value.
This default value will be used if you omit it in your definition. For
example, a component AString representing a string attribute has a
default value of 255 assigned to its width. This default value
may, or may be not, what you need. To avoid the unnecessary overhead of
overwriting the defaults in each component AString, you can set a
different default for one, or more, of its properties:
AString.defaults['width']=30 AString.defaults['externalType']='TEXT'
This is a general mechanism that you can use for every single property defined
by a component, simply by changing the corresponding entry in the component
class's dictionary defaults.
