构造器概要

构造器
构造器和说明
`ChangeableHighlightPainter()` Creates a new `ChangableHighlightPainter` that paints highlights with the text area's selection color (i.e., behaves exactly like `javax.swing.text.DefaultHighlighter.DefaultHighlightPainter`).
`ChangeableHighlightPainter(java.awt.Paint paint)` Creates a new highlight painter using the specified `Paint` without rounded edges.
`ChangeableHighlightPainter(java.awt.Paint paint, boolean rounded)` Creates a new highlight painter.
`ChangeableHighlightPainter(java.awt.Paint paint, boolean rounded, float alpha)` Creates a new highlight painter.

方法概要

`float`	`getAlpha()` Returns the alpha value used in computing the translucency of these highlights.
`java.awt.Paint`	`getPaint()` Returns the `Paint` (usually a `java.awt.Color`) being used to paint highlights.
`boolean`	`getRoundedEdges()` Returns whether rounded edges are used when painting selections with this highlight painter.
`void`	`paint(java.awt.Graphics g, int offs0, int offs1, java.awt.Shape bounds, javax.swing.text.JTextComponent c)` Paints a highlight.

```
public ChangeableHighlightPainter()
```
    Creates a new ChangableHighlightPainter that paints highlights with the text area's selection color (i.e., behaves exactly like javax.swing.text.DefaultHighlighter.DefaultHighlightPainter).
  - ChangeableHighlightPainter
```
public ChangeableHighlightPainter(java.awt.Paint paint)
```
    Creates a new highlight painter using the specified Paint without rounded edges.
    
    参数:
    paint - The Paint (usually a java.awt.Color) with which to paint the highlights.
  - ChangeableHighlightPainter
```
public ChangeableHighlightPainter(java.awt.Paint paint,
                          boolean rounded)
```
    Creates a new highlight painter.
    
    参数:
    paint - The Paint (usually a java.awt.Color) with which to paint the highlights.
    rounded - Whether to use rounded edges on the highlights.
  - ChangeableHighlightPainter

public ChangeableHighlightPainter(java.awt.Paint paint,
                          boolean rounded,
                          float alpha)
```
    Creates a new highlight painter.
    
    参数:
    paint - The Paint (usually a java.awt.Color) with which to paint the highlights.
    rounded - Whether to use rounded edges on the highlights.
    alpha - The alpha value to use when painting highlights. This value should be in the range 0.0f (completely transparent) through 1.0f (opaque).
- 方法详细资料
  - getAlpha
```
public float getAlpha()
```
    Returns the alpha value used in computing the translucency of these highlights. A value of 1.0f (the default) means that no translucency is used; there is no performance hit for this value. For all other values ([0.0f..1.0f)), there will be a performance hit.
    
    返回:
    The alpha value.
    另请参阅:
    setAlpha(float)
  - getPaint
```
public java.awt.Paint getPaint()
```
    Returns the Paint (usually a java.awt.Color) being used to paint highlights.
    
    返回:
    The Paint.
    另请参阅:
    setPaint(java.awt.Paint)
  - getRoundedEdges
```
public boolean getRoundedEdges()
```
    Returns whether rounded edges are used when painting selections with this highlight painter.
    
    返回:
    Whether rounded edges are used.

public void paint(java.awt.Graphics g,
         int offs0,
         int offs1,
         java.awt.Shape bounds,
         javax.swing.text.JTextComponent c)
```
    Paints a highlight.
    
    指定者:
    
    paint 在接口中 javax.swing.text.Highlighter.HighlightPainter
    
    参数:
    g - the graphics context
    offs0 - the starting model offset >= 0
    offs1 - the ending model offset >= offs1
    bounds - the bounding box for the highlight
    c - the editor
  - paintLayer
```
public java.awt.Shape paintLayer(java.awt.Graphics g,
                        int offs0,
                        int offs1,
                        java.awt.Shape bounds,
                        javax.swing.text.JTextComponent c,
                        javax.swing.text.View view)
```
    Paints a portion of a highlight.
    
    指定者:
    
    paintLayer 在类中 javax.swing.text.LayeredHighlighter.LayerPainter
    
    参数:
    g - the graphics context
    offs0 - the starting model offset >= 0
    offs1 - the ending model offset >= offs1
    bounds - the bounding box of the view, which is not necessarily the region to paint.
    c - the editor
    view - View painting for
    
    返回:
    region drawing occurred in
  - setAlpha
```
public void setAlpha(float alpha)
```
    Sets the alpha value used in rendering highlights. If this value is 1.0f (the default), the highlights are rendered completely opaque. This behavior matches that of DefaultHighlightPainter and imposes no performance hit. If this value is below 1.0f, it represents how opaque the highlight will be. There will be a small performance hit for values less than 1.0f.
    
    参数:
    alpha - The new alpha value to use for transparency.

    getAlpha()
  - setPaint
```
public void setPaint(java.awt.Paint paint)
```
    Sets the Paint (usually a java.awt.Color) used to paint this highlight.
    
    参数:
    paint - The new Paint.
    另请参阅:
    getPaint()
  - setRoundedEdges
```
public void setRoundedEdges(boolean rounded)
```
    Sets whether rounded edges are used when painting this highlight.
    
    参数:
    rounded - Whether rounded edges should be used.
