Greg Brown commented on PIVOT-633:
----------------------------------
Note that, in order to use the geom primitives effectively, the current stroke
must be taken into account. For example, rather than drawing a rectangle with a
stroke thickness of 1 at 0, 0, it should be drawn at 0.5, 0.5 with a width and
height of one less than the actual bounds.
> Eliminate use of GraphicsUtilities.drawRect() and drawLine()

> Key: PIVOT-633
> URL: https://issues.apache.org/jira/browse/PIVOT-633
> Project: Pivot
> Issue Type: Improvement
> Components: wtk
> Reporter: Greg Brown
> Priority: Minor
> Fix For: 2.0
>
>
> These methods were originally created to provide better rendering behavior
> than the corresponding java.awt.Graphics#drawRect() and drawLine() classes.
> However, a better approach is to call Graphics2D#draw() with a Rectangle2D or
> a Line2D. This produces much better results when the display is scaled, since
> these primitives use true floating point values.
> A number of components including most buttons have already been updated to
> use the java.awt.geom classes, but many skins are still using
> GraphicsUtilities and should also be updated.
