Hi there,
I've got a subclass of PrintGraphicalViewerOperation to print the
content of ma graphical Viewer with pagebreaks and footer on every page.
The printoperation does work without complaints.
The only thing that does not work as desined is that my
ConnectionEditParts having lineStyle LINE_DASH are printed as if they
where LINE_SOLID.
Does anybody know what I must do in order to get the correct linestyle
printed?
I added a snippet with the overriden method in
PrintGraphicalViewerOperation below.
Additional Info:
I did set the linestyle of my Connection using
((PolylineConnection) connection).setLineStyle( Graphics.LINE_DASH );
in the createFigure()-Method of my EditPart.
The Connections are routed using ManhattenRouter.
OS: Windows XP
Eclipse Galileo(Build id: 20090619-0625) with
'org.eclipse.gef_3.5.0.v20090528-1511.jar'
Thanks for all your help and advices
Alex
