Package javax.swing.plaf.synth Description
Synth is a skinnable look and feel in which all painting is
delegated. Synth does not provide a default look. In
order to use Synth you need to specify a
file, or
provide a SynthStyleFactory . Both
configuration options require an
understanding of the synth architecture, which is described
below, as well as an understanding of Swing's architecture.
Unless otherwise specified null is not a legal value to any of
the methods defined in the synth package and if passed in will
result in a NullPointerException .
Synth
Each ComponentUI implementation in Synth associates
itself with one SynthStyle per Region , most
Components only have one Region and
therefor only one SynthStyle .
SynthStyle
is used to access all style related properties: fonts, colors
and other Component properties. In addition
SynthStyle s are used to obtain
SynthPainter s for painting the background, border,
focus and other portions of a Component . The ComponentUI s obtain
SynthStyle s from a
SynthStyleFactory .
A SynthStyleFactory
can be provided directly by way of
SynthLookAndFeel.setStyleFactory(javax.swing.plaf.synth.SynthStyleFactory) ,
or indirectly by way of
SynthLookAndFeel.load(java.io.InputStream, java.lang.Class>) . The
following example uses the SynthLookAndFeel.load()
method to configure a SynthLookAndFeel and sets it
as the current look and feel:
SynthLookAndFeel laf = new SynthLookAndFeel();
laf.load(MyClass.class.getResourceAsStream("laf.xml"), MyClass.class);
UIManager.setLookAndFeel(laf);
Many JComponent s are broken down into smaller
pieces and identified by the type safe enumeration in
Region . For example, a JTabbedPane
consists of a Region for the
JTabbedPane (Region.TABBED_PANE ), the content
area (Region.TABBED_PANE_CONTENT ), the
area behind the tabs (Region.TABBED_PANE_TAB_AREA ), and the
tabs (Region.TABBED_PANE_TAB ). Each
Region of each
JComponent will have a
SynthStyle . This allows
you to customize individual pieces of each region of each
JComponent .
Many of the Synth methods take a SynthContext . This
is used to provide information about the current
Component and includes: the
SynthStyle associated with the current
Region , the state of the Component
as a bitmask (refer to SynthConstants for the valid
states), and a Region identifying the portion of
the Component being painted.
All text rendering by non-JTextComponent s is
delegated to a SynthGraphicsUtils , which is
obtained using the SynthStyle method
SynthStyle.getGraphicsUtils(javax.swing.plaf.synth.SynthContext) . You can
customize text rendering
by supplying your own SynthGraphicsUtils .
Notes on specific components
JTree
Synth provides a region for the cells of a tree:
Region.TREE_CELL . To specify the colors of the
renderer you'll want to provide a style for the
TREE_CELL region. The following illustrates this:
<style id="treeCellStyle">
<opaque value="TRUE"/>
<state>
<color value="WHITE" type="TEXT_FOREGROUND"/>
<color value="RED" type="TEXT_BACKGROUND"/>
</state>
<state value="SELECTED">
<color value="RED" type="TEXT_FOREGROUND"/>
<color value="WHITE" type="BACKGROUND"/>
</state>
</style>
<bind style="treeCellStyle" type="region" key="TreeCell"/>
This specifies a color combination of red on white, when
selected, and white on red when not selected. To see the
background you need to specify that labels are not opaque. The
following XML fragment does that:
<style id="labelStyle">
<opaque value="FALSE"/>
</style>
<bind style="labelStyle" type="region" key="Label"/>
JList and JTable
The colors that the renderers for JList and JTable use are
specified by way of the list and table Regions. The following
XML fragment illustrates how to specify red on white, when
selected, and white on red when not selected:
<style id="style">
<opaque value="TRUE"/>
<state>
<color value="WHITE" type="TEXT_FOREGROUND"/>
<color value="RED" type="TEXT_BACKGROUND"/>
<color value="RED" type="BACKGROUND"/>
</state>
<state value="SELECTED">
<color value="RED" type="TEXT_FOREGROUND"/>
<color value="WHITE" type="TEXT_BACKGROUND"/>
</state>
</style>
<bind style="style" type="region" key="Table"/>
<bind style="style" type="region" key="List"/>
