Hi
Now I want to remove some focus decorations in my figure when it is
selected.For example:
In GEF when I selected an figure to resize or to move the figure will be
added some decorations which has eight squares. and when use move the
mouse on the figure the cursor will change to resize cursor or move
cursor.What I want is to remove all squares and only when I move mouse on
the right bound or left bounds the cursor will change to the resize cursor
and so does the move cursor.
Should I add some selectinEditPolicy extends from Resizable or
NonResizable EditPolicy?
Can you help me?
Daniel
thanks in advance.

i don't know the best answer, but what you suggested is exactly what i do
to modify the selection decoration.

i created a editpolicy with a new implementation of
createSelectionHandles() then use it by setting it up in my Diagrams main
edit policy as such:

public class DiagramComponentRoleEditPolicy extends XYLayoutEditPolicy {
protected EditPolicy createChildEditPolicy(EditPart child) {
return new MyNewEditPolicyToControlHandles();
}

you'd probably still want to create "handles" from the existing MoveHandle
and ResizeHandle, but give them no graphically representation, i.e. empty
paintFigure() implemntation. then you can get all the existing code
behind the handles for managing the resizing, positioning, cursors, etc.
