Greetings,
I have a container edit part whose content pane's size should be always
as specified in the size properties of its model. Therefore, whenever
the edit part's model's size properties change, I'm setting the edit
part's content figure size using setMinimumSize(), setPreferredSize()
and setMaximumSize() (just setting the preferred size isn't enough, but
that's another story). This works fine whenever the model's size grows,
but doesn't work when it shrinks.
The edit part's figure looks as follows:
+-------------+
| title |
+-------------+
| |
| layeredPane |
| |
+-------------+
The title and layered pane are laid out using a ToolbarLayout. The
layeredPane contains three layers, one of which is the content pane. The
contentPane is the only figure with children, and it's using an XYLayout.
Why won't the edit part's figure shrink? How do I fix this?
Thank you very much in advance,
Martijn.

Perhaps the other layers in the layered pane are returning preferred sizes
bigger than the content pane because they were previously sized to be that
big when the content pane reported that size.

Was this a bug in my code or in GEF's code?
It seems to be related to the fact that the layer doesn't have a layout
manager. In that case Figure.getPreferredSize() returns getSize(). Why
doesn't it return a (0, 0) dimension?
Regards,
Martijn.

In your code.

Since a figure's intial size is 0,0, it would have returned that; however,
since it had been resized it's returning that size as its preferred one
(which is a useful default). If you were to set the size of a
RectangleFigure to be 100x100, you'd want it to maintain that size. The
proper thing is to set the layer's preferred size or give it the capability
to calculate its actual preferred size (by setting a layout manager).
