| [Zest/Draw2d] Custom figure button event [message #247248] |

Hello everybody,
I have a Zest graph to which a custom figure can be added. The simplest
graph looks like this:
--------------
| Step 2 | + | <- StepFigure extends IFigure
--------------
| Document | <- DocumentFigure extends IFigure
--------------
^
|
|
--------------
| Step 1 | + | <- StepFigure extends IFigure
--------------
<- DocumentFigures aren't displayed...
Via the plus button document figures can be added to the step figure.
This works perfectly - but only for the last step figure added to the
graph (in this case Step 2). A document figure can be added to any other
step figure (here Step 1) but it isn't displayed. I've tried calling
revalidate and repaint on the step figure in question but that didn't
help. Does anybody know what I'll have to do to force Step 1 to display
the document figures added?
Kind regards,
Bianca

>> It is likely a layout issue.
I've had some more time to debug and found the following.
AbstractLayout#getPreferredSize returns the preferredSize of the figure
to which other figures can be added with no problem. So when I set the
preferredSize to null while debugging this code was run:
Thread [main] (Suspended (breakpoint at line 164 in ToolbarLayout))

The thing that differs now from the other figure that does resize when a
figure is added to it is this code. But I have no idea where that might
be triggered...

I found two solutions:
1) override the method getSize() of GraphNode and return a new
Dimension(-1,-1);
2) When you are collapsing/expanding, before call the algorithm, get the
node's figure and do:
Point loc = getLocation();
Dimension size = new Dimension(-1,-1);
Rectangle bounds = new Rectangle(loc, size);
fig.getParent().setConstraint(fig,bounds);
// Call the collapse/expand algorithm
:)
