Description Jürgen Gluch 2014-07-07 08:43:17 CDT

after my update of Fiji (Windows 7 64bit) the icons on my custom
action bar do not show up. Only the text ist shown. The macros work
like before. Unfortunately the build in demo bar shows icons, but any
test to call a separate custom action bar with icons loaded from file
fails. Any idea whats broken?

I uploaded a "sample image" as advised in the mailing list: fiji-win64-20140707032800.zip
Then I copied the subfolder /icon/ in the ActionBar folder, same location as original data.

If the action bar is started by this line of macro code:
  run("Action Bar","/plugins/ActionBar/_test.txt");
it shows up, works correct, bu the icon is missing and the text label is displayed.

Same con on an older Fiji at the same computer (IJ 1.48r) works as usual. So I don#t think it is related to a system wide error in my Win64 or Java.

I can confirm that after a recent FIJI/IMAGEJ2 update, actionbars cannot fnd their icons any more. In the ActionBar plugin, the icon path is built from info in the configuration file and finally looks like this:

"icons/_test/test.png"
then I used the following to get it's URL:
imageURL = Action_Bar.class.getResource(imgLocation);
This used to work fine and return a valid URL for the icon located in plugins/ActionBar/icons/_test/test.png but now returns NULL.

Thanks for any pointer about how I could work around this while also keeping it working with IJ1.

Something changed about how classes are loaded in Fiji, and the classloader getResource(resource) method can't find resources relative to the class location.
A version of ActionBar with a workaround of this feature can be found at http://imagejdocu.tudor.lu/doku.php?id=plugin:utilities:action_bar:start&#downloads
