paintSyntaxLine()

static int net.sf.gridarta.textedit.textarea.SyntaxUtilities.paintSyntaxLine ( final Segment  line, final Iterable< Token >  tokens, final SyntaxStyles  styles, final TabExpander  expander, final Graphics  gfx, final int  x, final int  y  )

static

Paints the specified line onto the graphics context.

Note that this method modifies the offset and count values of the segment.

Parameters

line	the line segment
tokens	the token list for the line
styles	the syntax styles
expander	the tab expander used to determine tab stops. May be null
gfx	the graphics context
x	the x co-ordinate
y	the y co-ordinate

Returns

the x co-ordinate, plus the width of the painted string

Segment 

is equal to a string.

Parameters

ignoreCase	true if case should be ignored, false otherwise
text	the segment
