Constructor Summary

JavaView(javax.swing.text.Element e)
Creates a new JavaView and forwards down the element.

Method Summary

protected int	drawSelectedText(java.awt.Graphics g, int x, int y, int p0, int p1) Overridden from PlainView - this method gets called to render every element of selected text, so that I could change how it's displayed if I want.
protected int	drawTabbedText(java.lang.String s, int x, int y, java.awt.Graphics g, int startOffset, boolean selected, boolean inComment) Renders the text segment onto the given Grapnics context.
protected int	drawUnselectedText(java.awt.Graphics g, int x, int y, int p0, int p1) Overridden from PlainView - this method gets called to render every element of unselected text.
protected java.awt.Color	getColor(java.lang.String word) Returns the color to use on the given token.
static void	initColors() Initializes/resets the syntax coloring settings and special token table.

Constructor Detail

JavaView

public JavaView(javax.swing.text.Element e)

Creates a new JavaView and forwards down the element.

Method Detail

initColors

public static void initColors()

Initializes/resets the syntax coloring settings and special token table.

drawUnselectedText

protected int drawUnselectedText(java.awt.Graphics g,
                                 int x,
                                 int y,
                                 int p0,
                                 int p1)
                          throws javax.swing.text.BadLocationException

Overridden from PlainView - this method gets called to render every element of unselected text.

Overrides:

drawUnselectedText in class javax.swing.text.PlainView

javax.swing.text.BadLocationException

drawSelectedText

protected int drawSelectedText(java.awt.Graphics g,
                               int x,
                               int y,
                               int p0,
                               int p1)
                        throws javax.swing.text.BadLocationException

Overridden from PlainView - this method gets called to render every element of selected text, so that I could change how it's displayed if I want.

Overrides:

drawSelectedText in class javax.swing.text.PlainView

javax.swing.text.BadLocationException

drawTabbedText

protected int drawTabbedText(java.lang.String s,
                             int x,
                             int y,
                             java.awt.Graphics g,
                             int startOffset,
                             boolean selected,
                             boolean inComment)

Renders the text segment onto the given Grapnics context. Originally, this looked a lot like javax.swing.text.Utilities.drawTabbedText with a little bit of tokenizing, but now it's pretty much modified to my own style. Unfortunately, at some point in time, my indentation got all weird (probably as a result of me using tabs and the original implementation mixing spaces and tabs), so there may be some weird-looking parts left in the code. This is the magic of my syntax hilighting.

getColor

protected java.awt.Color getColor(java.lang.String word)

Returns the color to use on the given token. This will return the default foreground color, if no special color is assigned to that token.
