Hi!

What do the GEF experts suggest to use as edit part figures? Currently I
simply use icons but I want to change this to a better GEF conforming way
because I want to profit from zoom and print support. My icon figures are
printed as black boxes.

Any suggestions?

Thanks, Gunnar

PS: Is there a document on how print/zoom support works / will work? (e.g:
How to hide figures that should not be printed.)

The Figures in the Logic Example have recently been redone so they take
advantage of zoom support. Check out AndGateFigure, OrGateFigure, LEDFigure,
etc. These used to use icons, but now implement the paintFigure(Graphics)
method. This makes the figures look much nicer when zooming.

No documents as of yet. There are two examples in
org.eclipse.draw2d.examples entitled PrintExample and ZoomExample that show
the basics.

I noticed that printing in GEF works through an additional layer. Is that
right? So if I don't want the root diagram edit part to be printed do I have
to put in on another layer?

Right. The layers that will be printed are the layers which have been added
with the PRINTABLE_LAYERS constraint. See ScalableFreeformRootEditPart, this
is the root edit part used by the Logic Example. In its createLayers()
method it adds the primary layer and the connection layer as the printable
layers.

I looked through the ZoomExample. Will there be a generic GEF implementation
with something like zoom actions (like the alignment actions)?

How are colors managed? I noticed different colors for AndGateFigure and
OrGateFigure but it doesn't look like that #paintFigure handel color
management. Where is it implemented?

Thanks, Gunnar

The gate colors are set in their constructors via a
setBackgroundColor(Color) call. You can also manage colors by calls to
Graphics.setForegroundColor(Color) and Graphics.setBackgroundColor(Color)
within the paintFigure method. The background color will be used on fills,
the foreground color will be used on draws.

Yes, we are currently working on this and will put it into the logic
example.

To clarify, ONE layer is added with the PRINTABLE_LAYERS ID. This layer is
actually a LayeredPane containing the PRIMARY and CONNECTION layers.

We do not dispose Colors, if this is what you are asking.

GEF uses mostly System colors, so there is no reason to dispose them. The
Logic example uses a couple of more colors, but they are statically defined
and will remain in memory until you shutdown Eclipse.
