Hello,
once again I have to ask the question how to change the color of a
polyline connection. I know there have been several threads about this
topic, but everything I read about this hasn't solved the problem.
All polyline connections are drawn in a gray color, but the decorations
of the polyline have the correct color. It seems to be a general
problem, because I have the same problem with ellipse figures.
I tried to set the color of the connection only once and I did it in the
method refreshVisuals() of the EditPart.
I extend the class PolylineConnection in order to add some decorations
and a label to a polyline. May this be the problem?
Any suggestions would be appreciated.
Thanks, Alexander.

I know. But this doesn't work for my subclass of PolylineConnection. The
subclass is simple and jeust adds some decorations and a label to the
connection. The line doesn't change the color, even if I put the code of
the subclass in comments.
If I use just a PolylineConnection, the line has the correct color.
What might be the problem, when I extend PolylineConnection?
Am I allowed to extend PolylineConnection?
Thanks, Alexander.

I have a subclass of PolylineConnection like you and I set the foregroun=
d =
color in the constructor.
Maybe you could try to make some tests like overriding the outline (?) =
method like that
public void outline(Graphics g)
{
System.out.println(g.getForegroundColor());
super.outline(g);
}
just to see wich color is really used by the Graphics object to paint th=
e =
line ?
If it is not the one you choosed, probably the method getForegroundColor=
() =
called on the subclass of polylineconnection doesn't return the good =
color, so you could search in that direction...and if it is the one you =
=
choose...then I don't know...call an exorcist :D !
good luck,

Hi, regis!
Thanks for your idea. I finally solved the problem!!!
The graphics object had indeed the wrong foreground color. So I added a
call g.setForegroundColor() with the correct color and now it works...

Ok !
But that's still very strange...
A similar problem is I can't set at the same time the style AND the widt=
h =
of a polyline.
For example, I can't get a bold and dash polyline.
I write in the constructor of my subclass of PolylineConnection:
....
this.setLineWidth(2);
this.setLineStyle(SWT.LINE_DOT);
....
but it doesn't work.
It seems that this two lines can't stand each other !
Psychology of code lines is something strange, sometimes...they have =
feelings too, you know...

Ok so that's a known bug...thank you for your link...
I don't exactly know what it means to vote for it but I did it (I guess =
it =
increases the priority of the bug)...
