[Pythoncard-users] how to trigger on_closefield for the focused

[<bra...@om...>]

When a window closes, I want to prompted the user to save changes if 
needed. The script
below seems to work fine for that, except for one glitch: if the user 
edits a field, then clicks
the closebox on the window, an on_closefield never gets sent. I'd like to 
send a closefield
event to the widget that has the focus (if it's a field). I've tried using 
self.components.getFocus,
among other things...there must be something obvious I'm missing.

Thanks!


        def on_close (self, event):
                print 'caught a close window'
                if hasattr (self, 'entity'):
                        if len (self.entity.newData) > 0:
                                result = self.warningUnsavedChanges()
                                if result.accepted:
                                        if result.returnedString == 'No':
                                                print "Don't save changes; 
close window"
                                                self.revert()
                                                self.visible = False
                                        else:
                                                #save changes

                                                        self.visible = 
False
                                                except Exception, thisErr:
                                                        errMsg = 
str(thisErr)
 self.warningGeneral ('Problem saving changes: ' + errMsg)
                                else:
                                        pass #do nothing; do not close 
window
                        else:

                else:
                        print "this must not be a window with a DbEntity; 
nothing to save"
                        event.skip()
