    self.page = page 
    for wname in ['edtAddress', 'edtAmount'] : 
        def clearBackground(event, wname = wname) : 
            widget = getattr (self, wname) 
            widget.setStyleSheet ('') 
            widget.__class__.focusInEvent (widget, event) 
getattr (self, wname).focusInEvent = clearBackground 
self.cbMoniker.activated.connect (self.updateAvailableBalance) 
    self.btnPaste.clicked.connect (self.btnPasteClicked) 
    self.btnDelete.clicked.connect (clearBackground.btnDeleteClicked) 
    self.update ()
