[Gtk-sharp-list] Unselecting file in FileChooserButton

[Thorsten Schoel]

Hi,

I wondered if there was any way to let the user unselect a file he has
previously selected in a FileChooserButton. It obviously doesn't provide
this functionality itself. Using an extra widget and even an extra
dialog doesn't seem to work either because FileChooserButton's handler
for the Response event runs after mine and resets the selected file to
the one selected before the dialog was run on any response different
from Accept. Any help would be appreciated. Thanks,
Thorsten
