Figure.setBackgroundColor() and GEF 3.1 [message #192233]

I used org.eclipse.draw2d.Figure.setBackgroundColor() with no problem in GEF
3.0, but when using the new GEF 3.1 all my figures get a transparent
background.

Even I tried Figure.setOpaque(true);

Any one knows if anything have changed between 3.0 and 3.1 to explain this
behaviour, or is it a bug? Perhaps I missing something and it is my fault...

Any help would be greatly appreciated.

In 3.1, figures have no size when created (0,0) instead of (64,32) in 3.0.

Randy,

Thank you for your reply, but...

> In 3.1, figures have no size when created (0,0) instead of (64,32) in 3.0.

Do you think that this explain the behaviour I have seen.

Do you mean that I have to resize the figure before changing colors, and if
I resize the figure again I will have to call setBackgroundColor another
time. Is that correct?

It's the only thing I thought of. It could only explain the behavior if you
_never_ set the size of your figures.

Please post a snippet showing the problem.

Randy,

I found the problem. My figure extends Polygon and this extends Polyline,
you have changed Polyline and added setFill(false) to the instance
initializer:

public class Polyline extends Shape
{

PointList points = new PointList();
private static final int TOLERANCE = 2;
private static final Rectangle LINEBOUNDS = Rectangle.SINGLETON;

{
setFill(false); // This line is new 3.1
bounds = null;
}
....
....
}

Best regards,

Jose M Beleta
