Substance client properties

Client property name

Description

Client property name for specifying the corner radius for buttons. Currently, this property is respected only on toolbar buttons. This property can be set either as a client property on a specific toolbar button, a client property on a specific toolbar (will hold for all buttons in the toolbar) or as a global setting on UIManager. The value should be a Float instance.
