[Java-gnome-developer] Weird TreeModel / TreeView behaviour

[Andrew C. <an...@op...>]

Hey,

I've been experimenting with the TreeModel / TreeView APIs, and came
across something strange.

I've attached some example code. The CLASSPATH is correct for where the
[my] Gentoo ebuilds put the jars and .sos, but other than touching up
that it should just work if you type `make java` or `make native`

The specific thing I was testing was the ability to generate more than
one GtkTreeView based on a single underlying GtkTreeModel.

The strange behaviours I want to note are:

1) When you sort in one window, the other window is affected.

Run the program. You get two windows. There are three data columns; each
window (a TreeView) has two of them only. Click on a header, which
activates it as a sort column. That set of rows sort. SO DO THE ROWS IN
THE OTHER WINDOWS. Huh? Aren't the views supposed to be separate? Is
there some mismatch / object identity violation somewhere between the
Java layer and the underlying GObject layer?

2) When you close one window, the event isn't propagated to the
LifeCyleListener until the other window is also closed, when both events
show up. Try it. X close or Alt-F4 close one window. The way the code
is, that should cause an event, which calls Gtk.mainQuit, which should
cause the app to exit. That doesn't happen right.

I'm not sure that either of these are RC bugs, but they are certainly
anomolous.

I'd appreciate it if people could try this and let me know if they're
having the same behaviour. If you are, then we have some things we need
to track down.
