Hi Mouna,

Look at adding a MouseMotionListener to your Figure.

Cheers...
Anthony

If you are using GEF with draw2d, you should respond to requests to update
your figure's color. For example, SELECTION, SELECTION_HOVER, CREATION, and
CREATION_HOVER show feedback requests. This allows the color change to
happen in a certain context.

Hi Anthony,
the default color of my figure is red.
i have added a MouseMotionListner to my Figure. but as result was the
color changed (green )only one time : the first time, where the cursor
moved over the Figure.
when the cursor is not on Figure is the color always green .
Bút i want in this case that the figure set again the default color
(red).

have an Example for this ?

Thanks
Mouna

Hi Mouna,

There is a EllipseHitting example for the MouseMotionListner in the draw2d
examples:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.draw2d. examples/src/org/eclipse/draw2d/examples/hittest/EllipseHitt ing.java?cvsroot=Tools_Project

It does exactly what you are asking:
white ovals on a diagram, when you move your mouse over an oval it turns
yellow, move the mouse off and it turns white again.

Cheers...
Anthony
