public class RTextScrollPane
extends javax.swing.JScrollPane

An extension of JScrollPane that will only take RTextAreas (or javax.swing.JLayers decorating RTextAreas) for its view. This class has the ability to show:

• Line numbers
• Per-line icons (for bookmarks, debugging breakpoints, error markers, etc.)
• +/- icons to denote code folding regions.

The actual "meat" of these extras is contained in the Gutter class. Each RTextScrollPane has a Gutter instance that it uses as its row header. The gutter is only made visible when one of its features is being used (line numbering, folding, and/or icons).

构造器详细资料

RTextScrollPane

public RTextScrollPane()

Constructor. If you use this constructor, you must call setViewportView(Component) and pass in an RTextArea for this scroll pane to render line numbers properly.

RTextScrollPane

public RTextScrollPane(java.awt.Component comp)

Creates a scroll pane. A default value will be used for line number color (gray), and the current line's line number will be highlighted.

参数:

comp - The component this scroll pane should display. This should be an instance of RTextArea, javax.swing.JLayer (or the older org.jdesktop.jxlayer.JXLayer), or null. If this argument is null, you must call setViewportView(Component), passing in an instance of one of the types above.
