public class RSyntaxTextArea
extends RTextArea
implements SyntaxConstants

An extension of RTextArea that adds syntax highlighting of certain programming languages to its list of features. Languages currently supported include:

ActionScript
Assembler (X86)
BBCode
C
C++
CSS
C#
Clojure
Delphi
DTD
Fortran
Groovy
HTML
Java
JavaScript
JSP

LaTeX
Lisp
Lua
Make
MXML
NSIS
Perl
PHP
Ruby
SAS
Scala
SQL
Tcl
UNIX shell scripts
Windows batch
XML files

Other added features include:

Code folding
Bracket matching
Auto-indentation
Copy as RTF
Clickable hyperlinks (if the language scanner being used supports it)
A pluggable "parser" system that can be used to implement syntax validation, spell checking, etc.

It is recommended that you use an instance of RTextScrollPane instead of a regular JScrollPane as this class allows you to add line numbers and bookmarks easily to your text area.

```
    Templates are a shared resource among all instances of RSyntaxTextArea; that is, templates can only be enabled/disabled for all text areas globally, not individually, and all text areas have access of the same templates. This should not be an issue; rather, it should be beneficial as it promotes uniformity among all text areas in an application.
    For more flexible boilerplate code insertion, consider using the TemplateCompletion class in the AutoComplete add-on library.

```
protected void forceCurrentLineHighlightRepaint()
```
    Forces the current line highlight to be repainted. This hack is necessary for those situations when the view (appearance) changes but the caret's location hasn't (and thus the current line highlight coordinates won't get changed). Examples of this are when word wrap is toggled and when syntax styles are changed in an RSyntaxTextArea.

```
    Updates the current line highlight location.
  - processComponentEvent
```
protected void processComponentEvent(java.awt.event.ComponentEvent e)
```
    Overridden so we can tell when the text area is resized and update the current-line highlight, if necessary (i.e., if it is enabled and if lineWrap is enabled.
    
    覆盖:
    
    processComponentEvent 在类中 java.awt.Component
    
    参数:
    e - The component event about to be sent to all registered ComponentListeners.
  - setBackground
```
public void setBackground(java.awt.Color bg)
```
    Sets the background color of this text editor. Note that this is equivalent to calling setBackgroundObject(bg). NOTE: the opaque property is set to true when the background is set to a color (by this method). When an image is used for the background, opaque is set to false. This is because we perform better when setOpaque is true, but if we use an image for the background when opaque is true, we get on-screen garbage when the user scrolls via the arrow keys. Thus we need setOpaque to be false in that case.
    You never have to change the opaque property yourself; it is always done for you.
    
    覆盖:
    
    setBackground 在类中 javax.swing.JComponent
    
    参数:
    bg - The color to use as the background color.
  - setBackgroundImage
```
public void setBackgroundImage(java.awt.Image image)
```
    Sets this image as the background image. This method fires a property change event of type BACKGROUND_IMAGE_PROPERTY.
    NOTE: the opaque property is set to true when the background is set to a color. When an image is used for the background (by this method), opaque is set to false. This is because we perform better when setOpaque is true, but if we use an image for the background when opaque is true, we get on-screen garbage when the user scrolls via the arrow keys. Thus we need setOpaque to be false in that case.
    You never have to change the opaque property yourself; it is always done for you.
    
    参数:
    image - The image to use as this text area's background.
    另请参阅:
    getBackgroundImage()
  - setBackgroundObject
```
public void setBackgroundObject(java.lang.Object newBackground)
```
    Makes the background into this Object.
    
    参数:
    newBackground - The java.awt.Color or java.awt.Image object. If newBackground is not either of these, the background is set to plain white.
  - setCurrentLineHighlightColor
```
public void setCurrentLineHighlightColor(java.awt.Color color)
```
    Sets the color to use to highlight the current line. Note that if highlighting the current line is turned off, you will not be able to see this highlight. This method fires a property change of type CURRENT_LINE_HIGHLIGHT_COLOR_PROPERTY.
    
    参数:
    color - The color to use to highlight the current line.
    
    抛出:
    
    java.lang.NullPointerException - if color is null.

    参数:
    highlight - Whether or not to highlight the current line.
    另请参阅:
    getHighlightCurrentLine(), getCurrentLineHighlightColor(), setCurrentLineHighlightColor(java.awt.Color)
  - setLineWrap
```
public void setLineWrap(boolean wrap)
```
    Sets whether or not word wrap is enabled. This is overridden so that the "current line highlight" gets updated if it needs to be.
    
    覆盖:
    
    setLineWrap 在类中 javax.swing.JTextArea
    
    参数:
    wrap - Whether or not word wrap should be enabled.
  - setMargin
```
public void setMargin(java.awt.Insets insets)
```
    Overridden to update the current line highlight location.

    setMargin 在类中 javax.swing.text.JTextComponent
    
    参数:
    insets - The new insets.
  - setMarginLineColor
```
public void setMarginLineColor(java.awt.Color color)

```
    Sets the number of 'm' widths the margin line is over.
    
    参数:
    size - The margin size. #see #getDefaultMarginLinePosition
    另请参阅:
    getMarginLinePosition()
  - setRTextAreaUI
```
protected void setRTextAreaUI(RTextAreaUI ui)
```
    Sets the UI for this RTextArea. Note that, for instances of RTextArea, setUI only updates the popup menu; this is because RTextAreas' look and feels are independent of the Java Look and Feel. This method is here so subclasses can set a UI (subclass of RTextAreaUI) if they have to.
    
    参数:
    ui - The new UI.
    另请参阅:
    JTextComponent.setUI(javax.swing.plaf.TextUI)
  - setTabsEmulated
```
public void setTabsEmulated(boolean areEmulated)
```
    Changes whether or not tabs should be emulated with spaces (i.e., soft tabs). Note that this affects all tabs inserted AFTER this call, not tabs already in the document. For that, see convertTabsToSpaces() and convertSpacesToTabs().
    
    参数:
    areEmulated - Whether or not tabs should be emulated with spaces.
    另请参阅:
    convertSpacesToTabs(), convertTabsToSpaces(), getTabsEmulated()
  - setTabSize
```
public void setTabSize(int size)
```
    Workaround, since in JDK1.4 it appears that setTabSize() doesn't work for a JTextArea unless you use the constructor specifying the number of rows and columns...
    Sets the number of characters to expand tabs to. This will be multiplied by the maximum advance for variable width fonts. A PropertyChange event ("tabSize") is fired when the tab size changes.
    
    覆盖:
    
    setTabSize 在类中 javax.swing.JTextArea
    
    参数:
    size - Number of characters to expand to.
  - updateMarginLineX
```
protected void updateMarginLineX()
```
    This is here so subclasses such as RSyntaxTextArea that have multiple fonts can define exactly what it means, for example, for the margin line to be "80 characters" over.
  - yForLine
```
public int yForLine(int line)
             throws javax.swing.text.BadLocationException
```
    Returns the y-coordinate of the specified line.
    
    参数:
    line - The line number.
    
    返回:
    The y-coordinate of the top of the line, or -1 if this text area doesn't yet have a positive size or the line is hidden (i.e. from folding).
    
    抛出:
    
    javax.swing.text.BadLocationException - If line isn't a valid line number for this document.
  - yForLineContaining
```
public int yForLineContaining(int offs)
                       throws javax.swing.text.BadLocationException
```
    Returns the y-coordinate of the line containing an offset.
    
    参数:
    offs - The offset info the document.
    
    返回:
    The y-coordinate of the top of the offset, or -1 if this text area doesn't yet have a positive size or the line is hidden (i.e. from folding).
    
    抛出:
    
    javax.swing.text.BadLocationException - If offs isn't a valid offset into the document.
