filechooserbutton and saving

["Karl H. Beckers" <karl h beckers gmx net>]

Hi all,
can anybody explain why the filechooserbutton cannot popup an
filechooser with the save action?

And if that is an unavoidable truth, is there a way to get a button that
looks like the filechooserbutton but let's me control events (since I
can't seem to react on the filechooserbutton's button_press event
myself) ... and then short of reinventing the filechooserbutton ;S

TIA,

Karl.
