Subject: gui: Use dispose instead of finalize method in PsppireDataWindow.
X-Git-Tag: v0.7.8~16
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=pspp-builds.git;a=commitdiff_plain;h=bb41d678dd7dc31cb94e1848baae6d93dd8d2218

gui: Use dispose instead of finalize method in PsppireDataWindow.

According to the GObject reference manual, "When dispose ends, the
object should not hold any reference to any other member object."
That is, references should be dropped in dispose, not in finalize.
