I have an edit part that subclasses AbstractGraphicalEditPart, the figure for the part is a panel with a border layout, centred in that panel is another panel where the contents of the editpart go.
The internal frame has a FlowLayout.
My question is: how can I add an edit policy to the internal panel? Are edit policies created for edit parts, or are they created for figures?
Thanks.

I now have my contents panel returned as the contents pane, which makes the adding of children neater, but the edit policy is still operating on the main figure, not the contents pane.
Currently I am using the part's installEditPolicy() to add a FlowLayoutEditPolicy, but I get a class cast exception when I attempt the drag as the main figure's layout is a border layout, it is the contents pane that has the FlowLayout and the children I wish to drag.

There is a bug in FlowLayoutEditPolicy. Please override the following =
method:
protected boolean isHorizontal() {
IFigure figure =3D ((GraphicalEditPart)getHost()).getContentPane();
return ((FlowLayout)figure.getLayoutManager()).isHorizontal();
}
Opened: https://bugs.eclipse.org/bugs/show_bug.cgi?id=3D42406
