custom units via graphics object [message #132474]

Greeting once again!

I'm trying to use my own coordinate system (himetric) in my model and seem
to be having some difficulty. I thought that I might be able to create my
own Graphics object that functioned like the ScaledGraphics object. My new
Graphics object would wrap the swtgraphics and convert the hi-metric values
into smaller values to display. The figures look great and are getting
scaled correctly (96dpi / 25.4 / 100) but things like feedback and selection
aren't.

I've been digging through the code trying to see what I missed. I thought
that the SelectionTool would convert the mouse location based on zoom and
then search the figures for a hit. Any ideas?

thanks,
Jody

It sounds like you are not converting coordinates in your figure which
introduces the himetric function. For example, see ScaledFreeformLayer.
This figure not only creates the scaled graphics, but also extends
translateToParent and fromParent() so that feedback (which was originally
un-scaled) would appear correctly.

Yup, you're right. It seems that was what I was missing.

thanks,
Jody

I seem to be having troubles with creating bendpoints while zoomed. They
get created but the feedback is wrong.

Is there a bug in the ConnectionBendPointEditPolicy? I notice that the
NonResizeableEditPolicy translates the bounds for the feedback to be
displayed properly but I don't seem to see similar logic in the
ConnectionBendPointEditPolicy.

regards,
Jody

*blush* I think I found my problem. Apparently
ConnectionBendPointEditPolicy isn't in the gef framework. Sorry about the
confusion.

regards,
Jody
