LineNumberList

public LineNumberList(RTextArea textArea)

Constructs a new LineNumberList using default values for line number color (gray) and highlighting the current line.

参数:

textArea - The text component for which line numbers will be displayed.

LineNumberList

public LineNumberList(RTextArea textArea,
              java.awt.Color numberColor)

Constructs a new LineNumberList.

参数:

textArea - The text component for which line numbers will be displayed.

numberColor - The color to use for the line numbers. If this is null, gray will be used.

方法详细资料

addNotify

public void addNotify()

Overridden to set width of this component correctly when we are first displayed (as keying off of the RTextArea gives us (0,0) when it isn't yet displayed.

覆盖:

参数:

font - The new font to use for line numbers.

setLineNumberingStartIndex

public void setLineNumberingStartIndex(int index)

Sets the starting line's line number. The default value is 1. Applications can call this method to change this value if they are displaying a subset of lines in a file, for example.
