构造器详细资料

RSyntaxTextAreaUI

public RSyntaxTextAreaUI(javax.swing.JComponent rSyntaxTextArea)

Constructor.

方法详细资料

createUI

public static javax.swing.plaf.ComponentUI createUI(javax.swing.JComponent ta)

create

public javax.swing.text.View create(javax.swing.text.Element elem)

Creates the view for an element.

指定者:

create 在接口中 javax.swing.text.ViewFactory

覆盖:

create 在类中 RTextAreaUI

参数:

elem - The element.

返回:

The view.

createHighlighter

protected javax.swing.text.Highlighter createHighlighter()

Creates the highlighter to use for syntax text areas.

覆盖:

createHighlighter 在类中 javax.swing.plaf.basic.BasicTextUI

返回:

The highlighter.

getActionMapName

protected java.lang.String getActionMapName()

Returns the name to use to cache/fetch the shared action map. This should be overridden by subclasses if the subclass has its own custom editor kit to install, so its actions get picked up.

覆盖:

getActionMapName 在类中 RTextAreaUI

返回:

The name of the cached action map.

getEditorKit

public javax.swing.text.EditorKit getEditorKit(javax.swing.text.JTextComponent tc)

Fetches the EditorKit for the UI.

覆盖:

getEditorKit 在类中 RTextAreaUI

参数:

tc - The text component for which this UI is installed.

返回:

The editor capabilities.

另请参阅:

TextUI.getEditorKit(javax.swing.text.JTextComponent)

getRTextAreaInputMap

protected javax.swing.InputMap getRTextAreaInputMap()

Get the InputMap to use for the UI.

This method is not named getInputMap() because there is a package-private method in BasicTextAreaUI with that name. Thus, creating a new method with that name causes certain compilers to issue warnings that you are not actually overriding the original method (since it is package-private).

覆盖:

getRTextAreaInputMap 在类中 RTextAreaUI

paintBackground

protected void paintBackground(java.awt.Graphics g)

Paints the text area's background.

覆盖:

paintBackground 在类中 RTextAreaUI

参数:

g - The graphics component on which to paint.

paintMatchedBracket

protected void paintMatchedBracket(java.awt.Graphics g)

Paints the "matched bracket", if any.

参数:

g - The graphics context.

propertyChange

protected void propertyChange(java.beans.PropertyChangeEvent e)

Gets called whenever a bound property is changed on this UI's RSyntaxTextArea.

覆盖:

propertyChange 在类中 javax.swing.plaf.basic.BasicTextAreaUI

参数:

e - The property change event.

refreshSyntaxHighlighting

public void refreshSyntaxHighlighting()

Updates the view. This should be called when the underlying RSyntaxTextArea changes its syntax editing style.

yForLine

public int yForLine(int line)
             throws javax.swing.text.BadLocationException

Returns the y-coordinate of the specified line.

This method is quicker than using traditional modelToView(int) calls, as the entire bounding box isn't computed.

覆盖:

yForLine 在类中 RTextAreaUI

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 a specified offset.

This is faster than calling modelToView(offs).y, so it is preferred if you do not need the actual bounding box.

覆盖:

yForLineContaining 在类中 RTextAreaUI

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.
