Hi,
I am trying to create connections between two labels, which are decorated
with images. I use the following method to create the labels:
Label label = new Label("text", new Image(d, "d:\\mapitem_field.gif"));
now I want to get the location of the image in the label so that I can
make it as the anchor point for the connection between the labels.
currently I am using the follwing method to get the location:
Rectangle r = getOwner().getBounds().getCopy();
// return the rectangel of the label
return r.getRight();
can anyone tell me how I can revise the code above to get the location of
the image in the label? Thanks so much!

Hi Brian,
instead of org.eclipse.draw2d.geometry.Rectangle, the method
((Label)getOwner()).getIcon().getBounds() returns an instance of
org.eclipse.swt.graphics.Rectangle, which always returns x and y values of
0.
so i still don't know how I can get the position of the image rectangle
object.
Thanks,
Yabing

yabing,
Sorry, I checked the code right now and I you should use
Label#getIconBounds
That would make it
Rectangle r = ((Label)getOwner()).getIconBounds();
Hope that checks out :)
Brian.
