如何在 Kivy 中使用 fileChooser 选择多个文件？

问题描述

.py:

cmd.NewCmdRoot()

.kv

class file(Popup):
    load = Objectproperty()

class file1(Screen):
    file_path = StringProperty(None)
    the_popup = ObjectProperty(None)
    
    def select_to(self):
        self.the_popup= file(load=self.load)
        self.the_popup.open()
    def load(self,selection):
        pdf= FPDF()
        self.file_path = str(selection[0])
        self.the_popup.dismiss()
        imgs=[]
        imgs.append(self.file_path)
        for image in imgs:
            width,height= 0,0 
            pdf.add_page()
            pdf.image(image,width,height)
        pdf.save('name.pdf')

我有问题如何在一个 pdf 中选择多个图像？任何人都可以在此代码中提供帮助吗？

解决方法

def load(self,selection):
        pdf= FPDF()
        self.file_path = str(selection[0])
        self.the_popup.dismiss()
        imgs=[]
        imgs.append(self.file_path)
        for image in selection:
            width,height= 0,0 
            pdf.add_page()
            pdf.image(image,width,height)
        pdf.save('name.pdf')
