KIVY python: Slider inside ScrollView - slider

Question

I created a scroll view in which i put some labels and 2 sliders.
The scroll works perfectly, but I can't change the slider's value with my mouse...
Please run this code and see:
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label
from kivy.core.window import Window
from kivy.uix.button import Button
from kivy.uix.scrollview import ScrollView
from kivy.uix.gridlayout import GridLayout
from kivy.uix.slider import Slider
from kivy.uix.textinput import TextInput
class Home(BoxLayout):
def __init__(self, **kwargs):
super(Home, self).__init__(**kwargs)
self.layout = GridLayout(cols=1, padding=5, spacing=20, size_hint=(1, None))
self.layout.bind(minimum_height=self.layout.setter('height'))
for i in range(50):
if i%25==0:
btn = Slider(min=1, max=10, value=4)
else:
btn = Label(text=str(i), color=(0,0,0,1), size=(32, 32), size_hint=(1, None))
self.layout.add_widget(btn)
self.scrll = ScrollView(size_hint=(1, .6), pos_hint={'center_x': .5, 'center_y': .5}, do_scroll_x=False)
self.scrll.add_widget(self.layout)
self.add_widget(self.scrll)
class MyAppli(App):
def build(self):
Window.clearcolor = (1,1,1,1)
return Home()
if __name__ == '__main__':
MyAppli().run()

Okay when you work with slider you shall redefine the on_touch_down, on_touch_up and on_touch_move method to handle those events:
-main.py :
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label
from kivy.core.window import Window
from kivy.properties import NumericProperty
from kivy.uix.scrollview import ScrollView
from kivy.uix.gridlayout import GridLayout
from kivy.uix.slider import Slider
class Home(BoxLayout):
def __init__(self, **kwargs):
super(Home, self).__init__(**kwargs)
self.b = []
self.layout = GridLayout(cols=1, padding=5, spacing=20, size_hint=(1, None))
self.layout.bind(minimum_height=self.layout.setter('height'))
for i in range(50):
if i % 25 == 0:
self.b.append(MySlider(min=1, max=10, value=4, height=32, size_hint=(1, None)))
else:
self.b.append(Label(text=str(i), color=(0,0,0,1), height=32, size_hint=(1, None)))
self.layout.add_widget(self.b[i])
self.scrll = ScrollView(size_hint=(1, .6), pos_hint={'center_x': .5, 'center_y': .5}, do_scroll_x=False)
self.scrll.add_widget(self.layout)
self.add_widget(self.scrll)
def update(self, *args):
for i in range(50):
if i % 25 == 0:
self.b[i].begin = self.b[i].pos[0]
self.b[i].len = self.b[i].size[0]
class MySlider(Slider):
def on_touch_down(self, touch):
if self.collide_point(*touch.pos):
super(MySlider, self).on_touch_down(touch)
def on_touch_up(self, touch):
if self.collide_point(*touch.pos):
super(MySlider, self).on_touch_up(touch)
def on_touch_move(self, touch):
if self.collide_point(*touch.pos):
super(MySlider, self).on_touch_move(touch)
class MyAppli(App):
def build(self):
Window.clearcolor = (1,1,1,1)
return Home()
if __name__ == '__main__':
MyAppli().run()
-some outputs :
I hope this helps !
