Component Specific Properties

The look, and to some degree the feel of Synth can be customized by way of component specific properties. These properties are accessed from SynthStyle#get. Refer to synth file format for examples of how to specify these properties in a synth configuration file.

This file specifies the expected class type each of the values are to take. The behavior of supplying the wrong type is unspecified: typically a ClassCastException is thrown, but it is implementation specific.
