MetalTheme
provides the color palette and fonts used by
the Java Look and Feel.
MetalTheme
is abstract, see DefaultMetalTheme
and
OceanTheme
for concrete implementations.
MetalLookAndFeel
maintains the current theme that the
the ComponentUI
implementations for metal use. Refer to
MetalLookAndFeel.setCurrentTheme(MetalTheme)
for details on changing
the current theme.
MetalTheme
provides a number of public methods for getting
colors. These methods are implemented in terms of a
handful of protected abstract methods. A subclass need only override
the protected abstract methods (getPrimary1
,
getPrimary2
, getPrimary3
, getSecondary1
,
getSecondary2
, and getSecondary3
); although a subclass
may override the other public methods for more control over the set of
colors that are used.
Concrete implementations of MetalTheme
must return non-null
values from all methods. While the behavior of returning null
is
not specified, returning null
will result in incorrect behavior.
It is strongly recommended that subclasses return completely opaque colors.
To do otherwise may result in rendering problems, such as visual garbage.
