Hi,
I am trying to implement a functionality similar to the graph animation in
flow example.While analyzing the code,i saw that in ActivityDiagramPart a
custom figure is created with setBounds() overridden The only difference b/w
this overridden method and its super class one is that the following lines
have been deleted
"if (resize) invalidate();"
I couldnt get why this is done..Some performance reasons??When i use a
normal figure without this overridden method,the behaviour didnt show any
difference..
Can anyone clarify??
Thanks,
Zenil

The entire diagram is layed out in one place, and the results applied to all
figures in a preorder traversal of the figure tree. Avoiding the invalidate
just ensures that that figure doesn't layout again for no reason, since it
doesn't even know how to layout.
