[Repast-interest] Updating DisplaySurface

[Bryan R. <rio...@gm...>]

Hello,
 This should be an easy question for you experts... :-)
 So I'm creating a network comprised of nodes and edges and using=20
DisplaySurface to display it. My nodes are gray, with the border color=20
depending on what type of node it is. Some have yellow borders and some hav=
e=20
blue borders. Now, when a node gets disabled, it turns red and the border=
=20
stays the same color. I have a loop that goes through each node and=20
determines if it needs to be disabled and sets the disabled flag within tha=
t=20
object accordingly. The node objects extend DefaultDrawableNode, so when on=
e=20
is disabled, the setColor() function is called to change its color to red.=
=20
After I run through this loop, I call the repaint() method in the=20
DisplaySurface class to repaint the display so the disabled nodes are shown=
=20
as red. So this works fine. My problem, however, is this: the node can also=
=20
be disabled by checking a boolean box when it is probed. If the widget that=
=20
pops up when the node is probed covers the node, then when it is shut the=
=20
node is the correct color. However, if the widget was not covering the node=
,=20
then the color doesn't change. I'm assuming this is because the=20
DisplaySurface repaints the area that the widged covered and that's it (i'm=
=20
assuming this because if the widget covers half the node, then when it is=
=20
shut half the node turns red). Is there a function I can call from within m=
y=20
node object (which extends DefaultDrawableEdge) so that the node is=20
repainted when the boolean box is checked? I cannot call the repaint()=20
method from the node object because the DisplaySurface variable is not=20
visible to the object. The class that contains the DisplaySurface variable=
=20
is also the class that creates the node objects.
