Programmatic drawing in Pivot 2.0?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
- From the sound of things on
https://cwiki.apache.org/PIVOT/major-feature-changes-between-15x-and-20.html
I was one of the few people who used the "shape DOM" classes from
org.apache.pivot.wtk.media.drawing. I found the new Drawing and
SVGDiagramSerializer classes but those seem (at a glance) to require
loading up an SVG file from a stream. Is that so? Is there a way in
Pivot 2.0 to draw simple shapes programatically, as was possible in
Pivot 1.5?

Oh yes,
in development environment you have to add even plugin.jar (and maybe
even javaws.jar, both from jre/lib folder under the jdk folder), for
example in the jdk definition inside eclipse, so all compile without
problems.
I have to write something on this in our wiki (since many time, but I
never find time ... and now it's on my infinite todo list).
Greg wrote something like this in the wiki, but for Mac.

Hi there...I started working in the wtk module, but I can't manage to resolve
the dependency for netscape.javascript.JSObject, already checked in al the
pom files and haven't found that dependency :(

Hi,
you can find something here:
http://pivot.apache.org/tutorials/platform-overview.html
(and the same file is inside our distributions, so even in 1.5.2 you
should find it), but I understand that could not help so much (it
hasn't much detail for what you are searching).

Yes, we support SVG using SVGSalamander , maybe there you can find some more
info on drawing in Svg (if it's good for your case).
Or you can try to look at old classes in Pivot-1.5.2 and replicate/adapt
what you need.
Sorry but I can't help you more on this.
We are thinking to re-enable some old/dropped features adapting for the
current Pivot version, and moving them in one of our apache-extras project
related to Pivot.
But it's not on top of our priorities, and help/contributions are welcome
...

Hi, sorry at the moment I can tell you only a quick info:
Try to look at svg functions.
There was the old drawing package (with a clock demo) but if I remember well
should have been removed in 2.0 .
So good tests with SVG.

This should work. Are you sure the method isn't getting called? Perhaps you should place the call to super.paint() at the beginning of the method? Otherwise, your line may be painted over by the base class.

No worries at all, thank you for the tips. My project is a
graphics-heavy adaptation of a board game, which I imagine is far from
the most common Pivot use case. I'll look into making my own classes,
or maybe adapting and re-using the old classes from Pivot < 2.0.
Congrats on the new version!

Oh no! Sorry about that.
Pivot 2.0 still supports "immediate mode" drawing. You can do this in a couple of ways, but the easiest is to create a class that extends Panel and overrides paint(). Then you can use the drawing operations on the Graphics2D object passed to the method to draw your shapes. Pivot's "shape DOM" classes were mostly just wrappers around the drawing primitives in java.awt.geom anyways.
Hope this helps.
