Been playing around with GEF/draw2d for the past few days, and I have
found a possible bug in the RoundedRectangle figure (or in the underlying
Graphics class). When calling the setCornerDimensions(new Dimension(x,y))
method, if either or both of x or y are odd integers, the figure rendered
has vertical and/or horizontal whitespace in its fill. Try the following:
RoundedRectangle info = new RoundedRectangle();
info.setCornerDimensions(new Dimension(25,25));
info.setLayoutManager(new StackLayout());
info.setBackgroundColor(ColorConstants.lightGray);
info.setOpaque(true);
versus the following:
RoundedRectangle info = new RoundedRectangle();
info.setCornerDimensions(new Dimension(24,24));
...
etc.
Did a quick check of this list and bugzilla and saw nothing directly
related. Should I go ahead and enter into bugzilla?
Details on my platform: Linux (RH7.2), eclipse-2.1 motif

I tried this on Windows and didn't see the problem you describe. I'll
try it on Linux tomorrow. Here's my testcase.
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.draw2d.*;
import org.eclipse.draw2d.geometry.Dimension;
import org.eclipse.draw2d.geometry.Rectangle;
public class RRTest {
public static void main(String[] args) {
Shell shell = new Shell();
shell.setLayout(new FillLayout());
FigureCanvas canvas = new FigureCanvas(shell);
Figure contents = new Figure();
contents.setBackgroundColor(ColorConstants.white);
contents.setOpaque(true);
RoundedRectangle rr1 = new RoundedRectangle();
rr1.setCornerDimensions(new Dimension(25,25));
rr1.setLayoutManager(new StackLayout());
rr1.setBackgroundColor(ColorConstants.lightGray);
rr1.setOpaque(true);
rr1.setBounds(new Rectangle(10, 10, 100, 50));
contents.add(rr1);
RoundedRectangle rr2 = new RoundedRectangle();
rr2.setCornerDimensions(new Dimension(24,24));
rr2.setLayoutManager(new StackLayout());
rr2.setBackgroundColor(ColorConstants.lightGray);
rr2.setOpaque(true);
rr2.setBounds(new Rectangle(120, 10, 100, 50));
contents.add(rr2);
canvas.setContents(contents);
shell.open();
Display display = Display.getDefault();
while (!shell.isDisposed())
if (!display.readAndDispatch())
display.sleep();
display.dispose();
}
}

I found this to happen on both GTK and Motif. It turns out to be a bug in the
way GC fills its round rectangles. I opened a bug against SWT (#37623).
