Re: [JPP-Devel] LayerViewPanel Widget

Has anyone extracted the LayerViewPanel as a stand-alone widget for
Swing Programs?
I've used the LayerViewPanel and TreeLayerNamePanel in SMT - SAR
Manager Toolkit http://sarmanager.sourceforge.net/
I was thinking about doing this, or of coding something similar from
scratch, but I wanted to ask here first.
Current OpenJump places some constraints on what seems to be able to be
done easily. I had to make a few changes to get things to work, see:
http://sourceforge.net/p/sarmanager/code/HEAD/tree/trunk/SMT/lib/openjump1.4.3alpha_rev2524.patch
I also found that I needed to embedd these into a class that extended a
JInternalFrame:
public class MapInternalFrame extends JInternalFrame implements
LayerManagerProxy, LayerViewPanelProxy, TaskFrameProxy, LayerNamePanel,
LayerNamePanelProxy, SelectionManagerProxy { ...
http://sourceforge.net/p/sarmanager/code/HEAD/tree/trunk/SMT/src/net/aa3sd/SMT/ui/MapInternalFrame.java
I haven't gone digging very far, but it did find dependencies in the
OpenJump classes/interfaces on JInternalFrame (rather than the more
general JComponent) that appeared to prevent (unless I was missing
something) things like embedding a LayerViewPanel in a JPanel and a
TreeLayerNamePanel in another JPanel without there being an enclosing
JInternalFrame.
And, greetings to all. Have been lurking for a while, but haven't had
a chance to introduce myself, or describe what I've been trying to
accomplish with OpenJump. I keep hoping I'll have time to contribute,
particularly to improving support for projections, but haven't had a
chance to yet. Great platform, thanks to everyone involved for all the
good work.

Re: [JPP-Devel] SkyJUMP print code - need tester for detecting printers problem

The first is without a JobName attribute Debian squeeze with Java 7 returns the list of printers from lookupPrintServices without a job name and with a job name.
