Textfields delegator does not work

[sendog3c]

Hello community:

Here I am again looking for help about a textfields delegators. I have used the example of delegator found here but does not work to me. Would you please help explain me how it is works. Thanks.

import ui
import console

textfield1 = ui.TextField()
textfield2 = ui.TextField()
textview1 = ui.TextView()
label1= ui.Label()

class MyTextFieldDelegate (object):
    def textfield_should_begin_editing(self, textfield):
        alert_result = console.alert("textfield_should_begin_editing")
        
    def textfield_did_begin_editing(self, textfield):
    		alert_result = console.alert("textfield_did_begin_editing")
    		
    def textfield_did_end_editing(self, textfield):
    		alert_result = console.alert("textfield_did_end_editing")
    		
    def textfield_should_return(self, textfield):
    		alert_result = console.alert("textfield_should_return")
    		
    def textfield_should_change(self, textfield, range, replacement):
        alert_result = console.alert("textfield_should_change")
        
    def textfield_did_change(self, textfield):
        alert_result = console.alert("textfield_did_change")
        


def button_tapped(sender):
	
    button_definition = sender.title
    
    if button_definition == "SUM":
    	
    	label1 = sender.superview['label1'].text = "+"
    	
    	textfield1 = MyTextFieldDelegate()
    	
    	#sender.superview['textfield1'] = MyTextFieldDelegate()
    	
    if button_definition == "SUBS":
    	#alert_result = console.alert(button_definition)
    	label2 = sender.superview['label1'].text = "-"
    			
    if button_definition == "MULT":
    	#alert_result = console.alert(button_definition)
    	label3 = sender.superview['label1'].text = "*"	
    	
    if button_definition == "DIV":
    	#alert_result = console.alert(button_definition)
    	label4 = sender.superview['label1'].text = "/"	
    
def funcion_suma(sender, button_definition):
    	pass
    	
def funcion_multi(sender, button_definition):
    	pass
    	
def funcion_division(sender, button_definition):
    	pass

ui.load_view('MATHFUN').present('sheet')

@sendog3c said:

textfield1 = MyTextFieldDelegate()

You need to set your delegate as a delegate.

textfield1.delegate = MyTextFieldDelegate()

@sendog3c problem of sequence 😀

v = ui.load_view('MATHFUN')
v['textfield1'].delegate = MyTextFieldDelegate()
v.present('sheet')
