Hi all,
I have a problem. I have set the figure as Opaque. But still when I drag a
figure over another figure, I can view the figure in the background. All my
figures are drawn using the paintFigure() method. Can someone please tell
me, what could be the possible problem here?
Thanks,
Binti.

Here is a screen shot. Both these figures are opaque.

Binti,
Are you talking about the connections? Connections are always above the
other figures because the connection layer is above the layer on which the
figures are drawn.
Also, you cannot drag a figure "over" another figure. The order in which the
figures are drawn (which affects how figures overlap each other) depends on
their index in the list of their siblings.
Search for "z order" in this newsgroup - that thread should give you some
pointers.
Hope this helps,
Brian.

Are you invoking super.paintFigure() from your paintFigure() method?

That helps. But the z-order is another problem. I did not find much thread
on it. Could you explain how and where it is set. And how to change it?
Also, now the connections still show and as Brian explained, they will
always shpw as the connection layer is on the top of other layers...is there
a solution to it?
Thanks,
Binti.

The z-order is simply the order in which the figures are listed in the
parent (which is usually the order in which they were added). A figure will
paint over any of its preceding siblings. That is to say, with two
overlapping figures, the one that was added last will be on top. To change
this order, simply change their order in the parent figure's list.

Solution to what? Connections appearing over figures? So, you want your
connections to go under the figures? Switch the order in which the
connection layer and the primary layer added to the layered pane in the root
editpart. Same concept that I explained above.

setting opaque is not magic, it's just a boolean. You still need to call
super.paint(), or your bounds will not be filled in with the background
color.

The problem of adding the children in that order is solved. But I am unable
to figure out how have the layers been added. I guess this is being done
automatically. In my code I have not cretaed any layers. How do I handle
this?

It's in your root editpart. In your editor's configureGraphicalViewer()
method, you must be specifying a root editpart. Subclass that root
editpart's createPrimaryLayers() method or something like that.

I did what Pratik suggested and now things look good, but the only problem
is my connections are no longer selectable. How do I change this? Also, my
connections have labels attahced to them which do not show initially, but
once i close and reopen the diagram, they appear.
Please guide me though this too :)
