Greg Brown commented on PIVOT-633:
----------------------------------
Another thing that I don't like about GraphicsUtilities.drawRect() is the
automatic antialiasing. It isn't documented in the Javadoc and incurs a
performance penalty that the caller may not want or need.
Also, in order to perform the anti-aliasing, the implementation creates a copy
of the graphics context, which is more expensive than simply turning the AA key
on and then off later. But that can pretty easily be fixed.
> 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.
