## com.sas.graphics.components
Class TextStyle

    com.sas.graphics.components.TextStyle

Direct Known Subclasses:
  AdvancedTextStyle

    public class TextStyle

A TextStyle encapsulates the set of display properties applicable to text within a graph. Properties include: font, visibility, color, justification, frame and shadow.

Graphs contain NoteModels, AxisModels, LegendModels etc. that contain TextStyles. For instance a Legend has value text and label text hence the LegendModel has a ValueTextStyle and LabelTextStyle whereby the display properties of text can be specified.

Note that null is not an acceptable parameter value for the properties of this class and will result in an IllegalArgumentException being thrown. Due to the nature of the way GraphStyles are applied to graphs and the ways that various pieces of text are used differently in a graph there is not a good set of common default text properties. Some defaults are chosen when a TextStyle object is constructed but most of these are overridden by the graph's constructor or when a GraphStyle is applied to a Graph. Since there is not an acceptable default this class does not support any "revert to default" via null parameters.

## Usage

Ex. Set a bar chart's category axis label to dark blue.

     BarChart barChart = new BarChart();
     barChart.getBarChartModel().getCategoryAxisModel().getLabelTextStyle().setColor(Color.blue.darker());

## Behavior

This apply() method is a convenience to convey the properties from one TextStyle to another.

Constructor Detail

### TextStyle

    public TextStyle()

  A TextStyle encapsulates the set of display properties applicable to text used in graphs. The default font is a 12 point "TimesRoman" font. The default color is SystemColor.textText. The default visibility is true (means it is visible). The default justification is javax.swing.SwingConstants.CENTER. The default frameLineStyle is [color=java.awt.SystemColor.windowBorder; thickness=1 pixel; visibility=false] The default shadowStyle is the ShadowStyle defaults.

### TextStyle

    public TextStyle(java.awt.Font newFont,
                     java.awt.Color newColor,
                     int newJustification,
                     boolean newVisible)

  Constructor allowing specification of Font, color, justification and visibility. If newFont is `null` then it is ignored, the default font is ("TimesRoman",PLAIN,12). If newColor is `null` then it is ignored, the default color is SystemColor.textText. If newJustification is invalid then it is ignored, the default color is javax.swing.SwingConstants.CENTER. If newVisible is true then the text will be visible when displayed.

  Parameters:
    `newFont` - the text font, `null` is ignored
    `newColor` - the text color, `null` is ignored
    `newJustification` - the text justification, invalid value are ignored
    `newVisible` - the text visibility, true means visible

Method Detail

### apply

    public void apply(TextStyle theOtherObject)

  Utility method to convey properties contained in "theOtherObject" to this object.

  Note: Contained "models" (i.e. properties that are subclasses of ModelBase) will in turn be called on to convey their properties to the like contained models in the other object. In that respect this can be considered a "tree" type copy.

  Also Note: This is a deep copy. Thus after the copy, mutable properties will not be shared by the two instances.

  Parameters:
    `theOtherObject` - properties applied to this instance

### setFont

    `newFont` - the font to be used when drawing the text

    `java.lang.IllegalArgumentException` - if newFont is null.

### setColor

    public void setColor(java.awt.Color newColor)
                  throws java.lang.IllegalArgumentException
