self.kk = Button(text='pushme', size_hint=(0.15,0.15), background_color =[0,0,0,1])
self.add_widget(self.kk)
with self.kk.canvas.before:
BorderImage(
size=(self.kk.width + 20 , self.kk.height-7 ),
pos=(self.kk.x , self.kk.y),
border=(50, 50, 50, 50),
source='plain-white-background.jpg')
我想让边框图像更圆,所以我添加了“边框”,因为我虽然这会起作用,但我增加和减少了数字但没有区别,如果可能的话可以用 python 语言给我答案
