Cannot Load images into Carousel

[rPhoenix]

Hello everyone,

I'm a newbie here and trying to do some basic stuff. I am trying to make a carousel of images from the same directory. All images are numbered in a sequence. I can load one image fine, but I can't have it run multiple, Not sure what I'm missing here. I tried looking but no luck. I just don't understand it.

Any help appreciated.

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.carousel import Carousel
from kivy.uix.image import AsyncImage

kv = '''
Carousel:
    direction: 'right'
    AsyncImage:
        source: '1a.PNG'
    AsyncImage:
        source: '2a.PNG'
    AsyncImage:
        source: '3a.PNG'
'''

class NewProjectApp(App):
    def build(self):
        carousel = Carousel(direction='right')
        for i in range(4):
            src = " %d a.PNG" % i
            image = AsyncImage(source=src, allow_stretch=True)
            carousel.add_widget(image)
        return carousel

        return Builder.load_string(kv)


NewProjectApp().run()

Good news,  you are working too hard!

 

The code you put in build ‘overlaps’ with the code you have described in kv.  All you need to do is reduce most of the code in build.

For files that are local to your machine, you could simply use Image, rather than AsycImage.

 

Swipe right and you will see the next image.

 

from kivy.app import App
from kivy.lang import 

Builder

kv = '''

Carousel:
    direction: 'right'
    AsyncImage:
        source: '1a.PNG'
    AsyncImage:
        source: '2a.PNG'
    AsyncImage:
        source: '3a.PNG'
'''

class NewProjectApp(App):
    def build(self):
        return Builder.load_string(kv)


NewProjectApp().run()

Here is a version that automatically goes to the next slide every 4 seconds.

 

from kivy.app import App
from kivy.lang import Builder

from kivy.clock import Clock

kv = '''
Carousel:
    direction: 'right'
    loop: True

    AsyncImage:
        source: '1a.PNG'
    AsyncImage:
        source: '2a.PNG'
    AsyncImage:
        source: '3a.PNG'
'''

class NewProjectApp(App):
    def build(self):
        return Builder.load_string(kv)

    def on_start(self):
        Clock.schedule_interval(self.next_slide, 4)    # the number of seconds between slides...

    def next_slide(self, dt):
        self.root.load_next()


NewProjectApp().run()
