Hi ,
I am trying to implement this feautre. I got a GEF editor containing
Collapsible containers.These containers can have other containers and leaf
elments.Take for example
RootContainer
SubContainer1[Minimized state]
LeafElement1
SubContainer11
SubContainer2..[maximized state]
LeafElement2
SubContainer21
Now when i expand SubContainer1,i want SubContainer2 to move out from its
position relative to Subcontainer1,(sort of make way for
SubContainer1),and when i collapse it Subcontainer2(along with all its
children) should come back to its position relative to SubContainer1..
Right now when i expand/collapse a container,it overlaps on other elemnts
nearby(using XYLayout now)..Can XYlayout be customized to do this
behaviour??Or should i write a custom layout??If so what should i
concentrate on??
Thanks
Zenil

It's hard to imagine what you want these two containers to look like, but
you may be able to use existing layout managers. For example, the Palette
drawers are implemented using some of the included layouts in draw2d.

Hi Randy,
I need some more inputs.I have attached a screen shot explaining what i am
trying to do.
Does this specify the problem better??Now for solving this problem
should i go for a)try to customize some exisitng layouts b)creating my own
layout from scratch [if none of the existing layouts can be customized]
c)instead of using layouts,use an XYLayout,listen for expansion/collapsion
events,and try to compute the constraints and place my figures accordingly..
Thanks
Zenil

That looks like a tough problem and one that I haven't seen solved. Perhaps
you could use something like SWT's FormLayout. So instead of generating XY
constriants, you are generating attachements and offsets to nearby objects.
When the attachment moves, it pushes the other objects away.

He needs the figures to push things away in multiple directions on a plane,
not just in one direction such as the palette drawers.
One solution might be to use a CompoundDirectedGraphLayout. But this
wouldn't give users as much freedom to position nodes.

Hi Dhiraj and Randy,
Thanks for the inputs..Dhiraj,the ToolbarLayout solution is okey,but again
its in one direction..vertical/horizontal...
And I dont want to use CompoundedDirectedGraphLayout as i dont want to
layout things fully..And i dont want to write heavy-duty layout schemes like
FormLayout..
So here's what I am doing..As soon as user minimizes/maximizes a figure,i
based on a set of rules,recompute the positions of other figures in the
same parent.and lays it out.My goal is when u minimize,i want other figures
which are to the right/bottom of the minimized figure to "close in" near to
the mnimized figure.And when u maximize,i want figures to right/bottom to
"move out" in their respective directions if their current location
intersects with the bounds of the maximised figure..
Basically I think its just a set of computations that i should get
right,calculate each figure's initial state,each figure's final state,
pass it to the GraphAnimation routine in Flow example,and there..I get a
fantastic animated layout ..:)-[Infact i have almost achieved my goals..]
Cheers to GEF...
Rgds,
Zenil
