I just took a look at the code in the svn version of rox-lib2, and I
didn't see this... have you not yet checked it in?  I have a new
version anyway that adds the clear box *and* it will revert to being a
textbox if the GTK version is <2.6.

I also wasn't sure about what you meant by calling update_widget() -
I'm using the clear button callback to change the value of the
filechooser widget directly, which will update itself and call its own
'selection-changed' callback which will update the actual 'option'
value.

Here's the new builder:

def build_filechooser(self, node, label, option):
	"""<filechooser name=3D'...' label=3D'...'/>Tooltip</filechooser>.
	Lets the user choose a file (using a GtkFileChooser or by drag-and-drop).
	Note: Since the FileChooserButton widget requires GTK >=3D 2.6, lesser GTK
	versions will just show a normal text entry box, which should work with DN=
D.
	"""
	if g.gtk_version >=3D (2,6,0):
		filebutton =3D g.FileChooserButton(label)
		eb =3D g.EventBox()
		eb.add(filebutton)
		clearbutton =3D g.Button("Clear")
		self.may_add_tip(eb, node)
		hbox =3D g.HBox(False, 4)
		if label:
			hbox.pack_start(g.Label(label + ":"), False, True, 0)
		hbox.pack_start(eb, True, True, 0)
		hbox.pack_start(clearbutton, False, True, 0)
		self.handlers[option] =3D (
			lambda: filebutton.get_filename(),
			lambda: filebutton.set_filename(option.value))
		filebutton.connect('selection-changed', lambda w: self.check_widget(optio=
n))
		clearbutton.connect('clicked', lambda w: filebutton.set_filename("") )
		return [hbox]
	else:
		# Fallback to text input
		return self.build_entry(node, label, option)
