I´m using kivy + phyton for develop digital catalog for IOS and Androdi but i don´t know how I can reload image for this case.



On main.py



class Pgrid(Screen):
_ImagenFavorito = str

def get_ImgFavorito(self, arg):
img = arg
for i in range(len(Heart_Array)):
if Heart_Array[i][0] == img and Heart_Array[i][1] == 0:
return 'data/icons/black/heart_empty_icon&16.png'
else:
if Heart_Array[i][0] == img and Heart_Array[i][1] == 1:
return 'data/icons/black/heart_icon&16.png'

def update_corazon(self, picid):
#lg = picid
for i in range(len(Heart_Array)):
if Heart_Array[i][0] == picid:
Heart_Array[i][1] = 1
return 'data/icons/black/heart_icon&16.png'
pass


.kv file



<Pgrid>:
BoxLayout:
orientation: 'vertical'
canvas.before:
Color:
rgb: .9, .9, .9
Rectangle:
size: self.size
source: 'data/background_lite.png'
BoxLayout:
GridLayout:
rows: 3
colds: 4
spacing: 10
padding: 10, 10

#GRID 1.1
GridLayout:
rows: 2
clods: 1
Image:
id: pic11
source: 'data/products/camabe.jpg'
BoxLayout:
size_hint:1, 0.1
canvas.before:
Color:
rgba: 0, 0, 0, 0
Rectangle:
size: self.size
pos: self.pos
ImageButton:
id: 11
source: root.get_ImgFavorito(11)
#size_hint: .2, .2
pos_hint: {'center_y': 0.50, 'center_x': 0.50}
on_press: root.update_corazon(11)


When I run and click over ImageButton call roo.update_corazon(11) and update Heart_Array but I don´t know how reload the source ofo this ImageButton.



Any idea?
Thanks in advance





On my .py I change to this:



 def update_corazon(self, picid):
for i in range(len(Heart_Array)):
if Heart_Array[i][0] == picid:
Heart_Array[i][1] = 1
self.manager.current = 'pgrid'


And now I think self.manager.current = 'pgrid' will be reload Pgrid screen but don´t reload the screen :(

  • Finally I change many things like this and all work now: self.remove_widget(Pgrid(name='pgrid')) self.add_widget(Pgrid(name='pgrid')) and on .kv only -> on_press: root.update_corazon(xx)
