Hi Mikael:

It is non working still 🥺

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')

Hello here:

My code is presenting a syntax error. I have done all in possibilities to fix it but have been impossible to find what is happening.

I appreciate your help.

Regards

import ui

#w, h = ui.get_screen_size()
bw = 0
bh = 0
color1 = ''
equis = 60
yee = 140
ancho = 100
alto = 100
posicion = equis, yee, ancho, alto
bg_color1 = '#656ba9'

def button_tapped(sender):
    label.bg_color = sender.bg_color
    label.text = sender.title
    label.text_color = sender.tint_color
    

def make_button(color1, title, posicion):
    button = ui.Button(
        action=button_tapped,
        alignment=ui.ALIGN_CENTER,
        #bg_color=title.lower(),
        background_color = bg_color1,
        border_color='black',
        border_width=1,
        frame=(posicion),
        tint_color='white',
        title=title,
        corner_radius = 5)
        
    # it seems to be necessary to reset the frame
    #button.frame = (screen_x, h - 600, bw, bh)
    return button


label = ui.Label(
    alignment=ui.ALIGN_CENTER,
    bg_color='silver',
    background_color='black',

button3 = make_button(title = 'MULT', background_color='#1770a9', frame=(posicion))
button4 = make_button(title = 'DIV', background_color='#7c17a9', frame=(posicion)

view = ui.View(name='MATHGICIAN', background_color='#7f7f7f', frame=(10,10,400,700))
view.add_subview(label)
view.add_subview(button1)
view.add_subview(button2)
view.add_subview(button3)
view.add_subview(button4)
view.present('screen')```

What I want to know what button was tapped in order to use the correct Math operation (+ - * /) function o whatever that I coding

Thank both. Ben to help understand better the logic and ccc to become pro my code.

I would like to get the button title of my script to decide with math operation do. But I have problem with parameter, data gotten from sender (str, int).

I check an answer given to newbie (I did not remember exactly the user) an adapt it, but is not working properly. Here is the code.

Is a simply math app for my kids. In developing of course.

Thanks

Thank you Maikel let me to digest it 🤭🤭🤭😂😂😂😂😂, before implement

I want to disable a sub view, if I do that automatically all the buttons, textfield will be disable too.

Thanks.

It works. Thank you very much

Hi forum:

I need help to understand what is happening that the function does not give a good result.
Thanks.
