I just found out that Holongate has added new features for using Java2D from
within GEF/Draw2D. I just needed to change 3 lines in my code to got it
working for our editor.

It all looks extremely promising. Can't wait to try it out.

I went through most of the documentation - finding out how to download the
plugin was a bit of an exercise :)

Here's the link.

Keeping my fingers crossed,

Gunnar,

Thanks for the tip. Unfortunately I can't make this work with Eclipse +
GEF 3.0. The screenshots also suggest that the authors have developed it
on 2.x.

Hi Gunnar,

I was field testing the Holongate plugins with Eclipse 2.1.2 and GEF 2.1.2.
I managed to get the the plugins installed without any problems - I see the
Java2D support page in the Preference dialog and the demos on the "Rendering
Hints" page seem to work fast and fine.

I added the j2d4swt.jar to my plugins classpath and changed all references
to the following classes to their J2D counterparts
GraphicalEditorWithPalette, ScrollingGraphicalViewer,
ScalableFreeFormRootEditPart.

Somewhere in the overridden createGraphicalViewer(), I hit this exception..

java.lang.IllegalAccessError: tried to access class

.....

the code that leads up to this is ..
if (J2DRegistry.getHints().get(J2DGraphics.KEY_USE_JAVA2D) == Boolean.TRUE)

I don't really know what this key maps to in the preference page - but I
believe I have the necessary options turned on. Inspite of this, this value
is false and the BufferedGraphicsSource class is being loaded.

I don't really know if the problem is here, or elsewhere. The above happened
in GEF + Eclipse 2.1.0 as well.

Any ideas ?

Could you tell me what you changed to get your editor working ?

Thanks a bunch,
Brian.

There seems to be some classpath issues but got it working. Note that there
are still some painting issues when scrolling.

I checked out the two fragmens from SF CVS (org.holengate.draw2d/gef) and
placed them next two the GEF plugins (I use to have GEF plugins in my
workspace). Then I checkout the other holongate plug-ins. I had to modify
the classpath of my plug-ins to use the GEF fragements to resolve compile
issues but I didn't need to add something to my plugin.xml.

Note that the preferences are mixed up on every start. I have to open the
preference page once and toggle every preference off and on. The problem is
related to plugin startup/activation behavior. I fixed it locally in my
code. You can solve this by calling "Draw2dPlugin.getDefault" befor you
create any J2D stuff. This ensures that preferences are initialized
properties.

Brian,

I don't understand what kind of install you are using:
- either you use the plugins / fragments inside the workench
- either you use the standalone jars

If you are seeing the preference pages, i guess you are working inside the
workbench.
In that case, you don't have to add j2d4swt.jar in your plugin classpath but to
add a dependency on the relevant plugins through the PDE plugin.xml editor.

Mixing the two class loading mechanisms may lead to the kind of error you have.

Can you open a bug report on the SF Gunnar, i cannot reproduce your problem
(maybe a fresh install will reveal it).

It's on the homepage under "all downloads": as the website have been refreshed
with some delay, your navigator and its caching algorithm may have not seen the
change yet: can you try it now?

That's more than a suggestion: the plugins version number matches those of
Draw2d and GEF for that reason.
Unfortunalety, the matching rule is set to "Compatible" which means that a 3.0
GEF will satisfy the rule: this will be corrected in the next drop.

Christophe,

It sounds like you're a (the) man in the know. Is there plans to upgrade
the plugins to work with Eclipse 3.0?

Thanks.

As you may have noticed on the web site, there is effectively a 3.0 series underway.
But the goals (and the underlying technology) of the 3.0 plugins are not the
same due to the availability of the AWT_SWT bridge which allows you to embed AWT
widgets and all the Java2D stuff inside an SWT container.
A first release of the "Java2D support" for SWT 3.0 based on this new approach
is due by the end of this month: this is a preliminary release to check the
actual insterest of such a support.
I have no precise plan for a GEF/Draw2d support and even don't know if the
result will be satisfying or technically possible.
Anyway, if the community feedback is strong, it should be possible (and fast) to
upgrade the actual work to support SWT/GEF/Draw2d 3.0.

Please use the SourceForge services to post a feature enhancement so that i can
keep track of that topic.

For the little story:

Everything started with the SWT bug on win32: dashed lines of width > 1 are
displayed solid!

In fact, the SWT team have a high sensitivity to anything inside java.awt.*,
maybe with reason for some topics, maybe not.

All that stuff would be unecessary if the GC had a drawImage(BufferedImage
img,...) method, or if the GC was not a final class.

It is really a pity to see the work that have been done inside the ImageData
class to avoid having to write 'import java.awt.BufferedImage' inside an SWT class!

Having a fast, possibly native, method to convert a BufferedImage (or one of the
new Volatile, Offsreen variants) into an SWT Image would have preserved the time
of the SWT team, and the assets of the users.

Ok, the wrong drop has been delivered, it was only working for me!
The Draw2d actually implements the IStartup interface because, as you have
noticed, no method of the plugin triggers its loading before any preference is
loaded.

This is corrected for RC2, but i wait some more feedback before delivering it.
(but you can check out the CVS right now)

Hi Christophe,

First - thanks for the plugin & thanks for the prompt support.

I was using the binary distribution, I think the org.holongate.gef fragment
was /is missing from the distribution (org.holongate.j2d.gef is there
though). So I grabbed J2DGraphicalEditorWithPalette from the standalone jars
:) Bad move.

As Gunnar and you suggested, I'm now using the fresh and updated CVS
checkouts.

I've got compile issues now though - classes like
J2DGraphicalEditorWithPalette are defined in a fragment org.holongate.gef
and I can't add a fragment as a dependancy to my plugin. If I add the
fragment to the build path - compile issues are resolved, but I get a
NoClassDefFound exception on J2DGraphicalEditorWithPalette in the runtime
workspace - I guess this can be somehow fixed, but I had no success so far.

As a temporary hack, I ultimately got things working by copying the
org.holongate.gef packages into my plugin. I also created a
J2DScalableRootEditPart and J2DScalableLayeredPane (I don't want the
freeforms)

I've managed to see some darned good antialiasing :)

Great work - I (and I'm sure many others) be very happy to see the GEF
support for Eclipse / GEF 3. You have my vote !

Thanks again,
Brian.

Hi Christophe!

I downloaded the following archives:

org.holongate.draw2D_2.1.2RC1.zip
org.holongate.j2d.get_2.1.0RC1.zip
org.holongate.j2d_2.0.0RC2.zip

But I can't find any GEF class inside these archives (e.g.
j2DScalableFreeformRootEditPart, J2DGraphicalEditorWithPalette, .. and
so on).

May you help me?

Regards,

Holger

Use CVS to get the sources,
