Some methods on org.eclipse.draw2d.Graphics doesn't work on "Linux" if
antialising has been activated. I had the problem with
draw- & fillRoundedRectangle and with fillGradient.
I'm using cairo-0.1.23!

public class Snippet {

public static void main(String args[]) {
Display d = new Display();
final Shell shell = new Shell(d);
shell.setSize(400, 400);
LightweightSystem lws = new LightweightSystem(shell);
Figure contents = new Figure();
XYLayout contentsLayout = new XYLayout();
contents.setLayoutManager(contentsLayout);

Figure fig = new Figure() {

@Override
protected void paintClientArea(Graphics graphics) {
graphics.setForegroundColor(ColorConstants.black);
graphics.drawRoundRectangle(getBounds().shrink(1, 1), 50, 50);
// graphics.fillGradient(getBounds(), true);
}


@Override
public void paint(Graphics graphics) {
graphics.setAntialias(SWT.ON);
super.paint(graphics);
}

};
fig.setBounds(new Rectangle(100, 100, 100, 100));
contents.add(fig);

lws.setContents(contents);
shell.open();
while (!shell.isDisposed())
while (!d.readAndDispatch())
d.sleep();
}
}

You need Cairo 1.0 with Eclipse 3.2 integration builds. BTW, you shouldn't
be modifying the bounds directly as you do in the paintFigure() method.
Instead, do getBounds().getExpanded(-1,-1).

Eclipse 3.1 required and shipped Cairo 0.4.

Thank's it is working with cairo 1. It is possible to check if if
antialias (cairo) is available. In that way it would be possible to
activate antialias only if cairo has been installed.

regards

there's a

boolean advancedGraphicsInstalled = gc.getAdvanced();
gc.setAdvanced(false);

These methods aren't reflected in the Graphics class yet, though.

Hi Pratik,

how can I access the GC? The Graphic Context is hidden by SWTGraphics and
not accessible from outside.

Until then, as a workaround, you can create your own GC.

Are you saying invoking setAntiAlias() fails gracefully if Cairo is not
