Hi,

why is org.eclipse.draw2d.AbstractBackground not just an interface?

I want to implement a sub class of AbstractLabeledBorder which is also
an AbstractBackground. But I cannot do that because AbstractBackground
is not an interface.

My use case:

I want to draw a title text of a container figure which has also a
background. As I understood the AbstractBackground it should look like this:

+----------------------------+
|XTitletextXXXXXXXXXXXXXXXXXX|
+----------------------------+
| some other child figures |
| which are opaque themselves|
| and so no background from |
| container is visible |
+----------------------------+

The 'X' means here you can see the background of the border which is an
AbstractBackground.

With regards

Udo Walker
