[maemo-developers] Help with hildon.NumberEditor: IN PYTHON

[From: Darren Enns]

Help please!

I am slowly learning OOP-style PyGTK code, and have recently discovered 
how 'nasty' gtk.Spinbutton looks on Maemo :(

OK, so I was just going to make some quick changed to my Python code to 
use 'hildon.NumberEditor' instead, but it is not as much a 
'drop-in-replacement' as a newbie like me requires...

""" subclass the gtk.Digalog() class to create a new dialog window """
class spin_window(gtk.Dialog) :  
        value = [0] * SPIN_BUTTON_COUNT

        def hildon_set_value(self,widget,index):
           self.value[index] = widget.get_value()
           return

        # a callback to remember the values of the spin buttons.
        # the 'index' is setup when connecting the callback
        def set_value(self,widget,index):
           self.value[index] = widget.get_value_as_int()
           return

        def __init__(self,window):
                # init the parent class to create the dialog
                super(spin_window, self).__init__("set spin values", window,
                                gtk.DIALOG_DESTROY_WITH_PARENT | 
gtk.DIALOG_MODAL,
                                (gtk.STOCK_OK, gtk.RESPONSE_OK))

                number_editor = hildon.NumberEditor(-90,90)
                #number_editor.connect("changed",self.set_value, 0)
                #number_editor.connect("notify::value",self.set_value, 0)
                
number_editor.connect("notify::value",self.hildon_set_value,0)
                number_editor.set_value(0)
                self.vbox.pack_start(number_editor)
                self.value[0] = 0
                number_editor.show()

                label = gtk.Label('Latitude Degrees:')
                self.vbox.pack_start(label)
                #label.modify_font(pango.FontDescription("sans 30"))
                label.show()

                adjustment = gtk.Adjustment(0, -90, 90, 1, 1, 1)
                spinbutton = gtk.SpinButton(adjustment,0,0)
                spinbutton.connect("changed",self.set_value, 1)
                self.vbox.pack_start(spinbutton)
                self.value[1] = 0
                spinbutton.show()
...

Notice my feeble attempts to add 'special' code for the numbereditor -- 
but the code above does not work:

"TypeError: hildon_set_value() takes exactly 3 arguments (4 given)"

So I am getting all confused!  It *looks* like I am using the correct 
signal value, and passing three parameters...

There are very few Python examples out on Google for me to learn the 
solution with.

Thanks
