How I can reload an image on Kivy + Python
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 :(
python image kivy reload
