fpStack

This is the stack of formatting parameters.

itemCount

Total number of items we think we've added to the window.

lineAscent

Current lineAscent for this line.

lineDescent

Current lineDescent for this line.

lineStartIndex

notRendering

This is true when we're in a section that doesn't render.

  protected FormattingParameters currentParameters

Current formatting parameters.

  protected int x

Current X coordinate, where next display item will be added.

  protected int xlimit

Current X limit for the right margin. If a display item moves beyond xlimit, we wrap.

  protected int y

Current Y coordinate. This is the value of Y for the top of the current line we're building.

  protected int lineAscent

Current lineAscent for this line.

  protected int lineDescent

Current lineDescent for this line.

  protected int fontAscent

Current maximum font ascent.

  protected Font font

Current font as determined by the current FormattingParameters.

  protected FontMetrics fontmetrics

Metrics of the current font.

  protected Color color

Current color as determined by the current FormattingParameters.

  protected int lineStartIndex

The display item index of the first item on this line. This is used to go back to position all the items we accumulate on the line we're laying out right now.

  protected int itemCount

Total number of items we think we've added to the window.

  protected Stack fpStack

This is the stack of formatting parameters.

  protected int notRendering

This is true when we're in a section that doesn't render.

  protected int breakSoFar

This is used to combine requests to break a paragraph. This is how much of a break we have accumulated so far since we last wrapped. If a request to break is greater than this number, we bump the new Y position by that much further.

  public TextWindow win

This is the window we're laying objects out in.
