I have two screen classes ScreenOne and ScreenTwo and I would like to pass a value between them. I am using the ScreenManager and I am switching to the ScreenTwo using "self.manager.current() = "screen2"
I would like to do this without the use of a .kv file. I am not new to programming, but I am new to kivy and I did not expect this to be so complicated. Is there anyway I could pass a value through another manager function or something along those lines?
class ScreenOne(Screen):
def __init__(self,**kwargs):
super (ScreenOne,self).__init__(**kwargs)
my_box1 = GridLayout(cols=3,spacing=50,size_hint_y=None,size_y=100,)
my_box1.bind(minimum_height=my_box1.setter('height'))
drink_list = get_drink_list()
for drink in drink_list:
button = Button(text=drink,
size_hint_y=None, height=250, background_normal=get_drink_image(drink),font_size='15dp',color=[0,0,0,1])
button.bind(on_press=self.changer)
my_box1.add_widget(button)
root = ScrollView(size_hint=(None, None), size=(600, 400),
pos_hint={'center_x':.5, 'center_y':.5},bar_width='10dp')
root.add_widget(my_box1)
self.add_widget(root)
def changer(self, instance,*args):
self.manager.current = instance.text #button name
class ScreenTwo(Screen):
def __init__(self,**kwargs):
super (ScreenTwo,self).__init__(**kwargs)
# print drink_ordered
#creating layouts
my_box1 = GridLayout(cols=2)
description_box = BoxLayout(orientation='vertical', spacing=30)
#creating objects
drink_image = Image(source="drink_pics/" + self.name + ".jpg")
drink_name = Label(text=self.name,font_size='24dp',size_hint_y=None, height=100)
empty_box = Label(text="",font_size='24dp',size_hint_y=None, height=20)
ingredient_list = get_drink_ingredients(self.name)
description = ''
for count in range(len(ingredient_list)):
if ((count % 3 == 0) and (count != 0)):
description += "\n"
description += ingredient_list[count] + ", "
description = description[:-2]
description = description.replace('_', ' ')
drink_description = Label(text="Description: " + description,font_size='15dp'
,size_hint_y=None, height=100)
drink_order = Button(text="Order Drink",
size_hint_y=None, height=100, size_hint_x=None, width=385, padding=[100,100])
drink_order.bind(on_press=self.changer)
#adding to widgets
my_box1.add_widget(drink_image)
description_box.add_widget(drink_name)
description_box.add_widget(drink_description)
description_box.add_widget(drink_order)
description_box.add_widget(empty_box)

self.add_widget(my_box1)

self.manager.current = 'next screen'
