Current GtT will display e.g. XMLUtil (org.openide.xml) XMLUtil (org.netbeans.lib.updater) XMLUtil (org.netbeans.nbbuild) XMLUtils (java.util) XMLUtilTest (org.openide.xml) etc. The layout is rather clumsy, especially the parentheses (visually distracting), the package after the class (in contrast to the normal FQN display), and the lack of alignment. Suggest a simple change to a tabular format: org.openide.xml.XMLUtil org.netbeans.lib.updater.XMLUtil org.netbeans.nbbuild.XMLUtil java.util.XMLUtils org.openide.xml.XMLUtilTest This would still let you quickly see the class names and compare them, but you could also see the package names and FQNs quickly without having to move your eyes back and forth.
Hmm, I changed the color of the package name to gray recently so it should be easier to visually navigate to either class name or to package. I could teoretically implement the suggested tabular format, however it would have other drawbacks. 1) Need to compute all items renderers in advance to find out the correct width of the package column 2) If the dialog gets too small the ClassName instead of the package name would get hidden Reaassignig to Jano Rojcek to decide.
I will try the new appearance soon. #1 could be a real performance problem, I guess. (You could maybe adjust the column position in a renderer based on rows rendered so far - not sure if that works. Or you could guess based on String lengths of all items, if you have them all computed at once?) #2 might be a problem depending on how you set the default size of the dialog. Probably open to experimentation. Also see related issue #96878.
