[Java-gnome-developer] Problems with FileChooserWidget

[Igor F. <if...@re...>]

Hi everyone,

I'm a fairly new user to java-gnome, so please bear with me.

I seem to have some trouble with the FileChooserWidget. I first tried to
use it in a semi-complex window, and got the following error (and no
widget):
--------
org.gnu.glade.GladeXMLException: unknown widget class
'GtkFileChooserWidget'
	at org.gnu.glade.LibGlade.glade_xml_new(Native Method)
	at org.gnu.glade.LibGlade.<init>(LibGlade.java:97)
	at org.gnu.glade.LibGlade.<init>(LibGlade.java)
	at com.redhat.uicopy.WindowLauncher.<init>(WindowLauncher.java:17)
	at com.redhat.uicopy.WindowLauncher.main(WindowLauncher.java:26)
--------

Later on, I created a simple window and just stuck a file chooser in
there without any other sugar. Both of these experiments are using
Glade2. Again when I try to import this new glade file (with just the
window with the chooser) into my java app I get the same exception.

Does anyone have any idea on what might be causing this, or better yet,
a solution?

Thanks,
Igor
