Spent
the last afternoons working with Ruben Hinojo, who I met recently at
the Tinkerforge/NetBeans integration course
in Germany. He's Spanish, lives in Scotland, and joined
the course by
flying from Edinburgh to Amsterdam and then driving from there to
the
course in Germany. Since then he spent some days in Amsterdam and we've
been working a bit in a cafe in Amsterdam.
He's working freelance on a freight management system on
the NetBeans Platform and here's a pic of him and his application:
I showed him a few things to improve
the initial appearance of
the
application, such as removing
the unneeded tab in
the editor position
and displaying data at startup so that
the main window isn't empty
initially.
He, in turn, told me about something I didn't know about, where "freightViewer" below is an OutlineView:
void writeProperties(java.util.Properties p) {
// better to version settings since initial version as advocated at
// http://wiki.apidesign.org/wiki/PropertyFiles
p.setProperty("version", "1.0");
freightViewer.writeSettings(p, "FreightViewer");
}
void readProperties(java.util.Properties p) {
String version = p.getProperty("version");
freightViewer.readSettings(p, "FreightViewer");
}
The "OutlineView.read/writeSettings" enables you to save/restore
changes to an OutlineView, e.g., column width, column position, and
which columns are displayed/hidden.
In
the user dir, within
the .settings file of
the TopComponent (in
config/Windows2Local/Components), you'll then find content like this, where
the "FreightViewer" argument above is now
the prefix of
the name of each property element:
<?xml version="1.0" encoding="UTF-8" ?>

</properties>
NB: However, note as described in this issue,
i.e., since 7.2, hiding a column isn't persisted and in fact causes
problems. I replaced
the org-openide-explorer.jar with a previous one,
from 7.1.1, and then
the problem was solved. But now
the enhancements in
the OutlineView since 7.2 are no longer present, of course. So, looking
forward to seeing this problem fixed.
