外部按钮代码获取轮播图像属性

Question

我有这个代码，可以用路径上的图像填充我的轮播。

Python代码段...

class EzLaunchScreen(Screen):     
    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        img_path = ('D:\\Steven\Desktop\\Python App\\Images\\Carousel\\')
        # Funtion get images int carousel...
        layout = FloatLayout()
        self.background_image = Image(source='Images\launchScreen.png')
        carousel_widget = Carousel(direction ='right')
        for img_file in os.listdir(img_path):
            if img_file.endswith(('.png', '.jpg', '.jpeg')):
                img = Image(source=os.path.join(img_path, img_file))
                print(f"Adding image: {img_file}")
                carousel_widget.add_widget(img)       
        layout.add_widget(self.background_image)       
        layout.add_widget(carousel_widget)
        self.add_widget(layout)

在字符串片段中我有以下...

Code = '''
<EzLaunchScreen>: 
    brand_text: Brand_label  
    val_text: ToT_label
    slide_text: slider_label
    name: 'EzLaunch' 

   
    BoxLayout:  

        Button:
            background_color: 0, 0, 0, 0
            size_hint: .25, .070  
            on_press: app.swipe_me()  
            pos_hint: {'center_x': 0.10, 'center_y': .975} 

        # This is the carousel library of brands...
        Carousel: 
            id: carousel_widget        
            direction: 'right'
            on_slide: root.swipe_me()

'''

我想要一个函数，当我刷新轮播时给我带来图像名称... 这是我尝试过但行不通的方法...

def swipe_me(self, carousel_widget_instance, value):
        current_image = carousel_widget_instance.slides[carousel_widget_instance.index]
        image_name = current_image.image_name  # Access the stored name

        print(f"Current image name: {image_name}")

这是我过去一周在这个论坛上的第四篇文章，因此对任何人都没有回应。 我希望能得到一些方向... 与我的Excel帮助论坛不同，互联网没有任何真实的论坛为此...

提前感谢您...

这个解决方案...

carousel_widget.bind(_index=self.swipe_me)



 def swipe_me(self, instance, value):
            current_image = instance.slides[int(value)] 
            image_name = current_image.source.split('\\')[-1]
            image_name = image_name.split('.')[0]
            self.brand_text.text = image_name.upper()
            print(f"Image Name: {image_name.upper()}")

根据OP来解决问题，这解决了问题：

Answer 1

carousel_widget.bind(_index=self.swipe_me)
def swipe_me(self, instance, value):
    current_image = instance.slides[int(value)] 
    image_name = current_image.source.split('\\')[-1]
    image_name = image_name.split('.')[0]
    self.brand_text.text = image_name.upper()
    print(f"Image Name: {image_name.upper()}")
