Re: [gef-dev] Z Order API Change
|
Hi Ian,
Z-order is something a client would support in his diagram. Since all
diagrams need not support z-order, a breaking API change to the IFigure API
is not appropriate.
Why would you not be able to create your own interface to add to your
figure hierarchy, is something blocking this?
Cheers...
Anthony

|[gef-dev] Z Order API Change |
>--------------------------------------------------------------------------------------------------------------------------------------------------|
This is more of a development question, rather than a usage question, so
I am posting it here.
I am wondering if the IFigure API can be changed to add a
changeZOrder(IFigure child, int position)? I have a graph, and when I
select a node I would like it to appear on top. The usual method (remove
the node, then add it back) doesn't work in my case. I have 25 nodes
(containers) each with 256 children ~= 6400 nodes. Removing a container
(and firing all the listeners, etc...) takes about 1 1/2 seconds, a
considerable lag for a selection. I have experimented with simply
moving the container in the array of children (then calling invalidate /
repaint) and the performance is much better (since there is no need for
all the notifications)?
I will open a bug report, and even get a patch ready if this is
considered a good idea. However, I have a feeling that GEF doesn't
support this for a reason.
cheers,
Ian
