我試圖改變不同方法中按鈕的屬性。這是我目前正在使用:Kivy Python - 影響不同函數中的按鈕
def _finish_init(self, dt):
self.ids.grid_1.cols = 5
def callfun(self, *args):
self.ChangePic()
# Creating a variable to use to determine if the buttons should be editable
binded = 0
# Loop to make 15 different buttons on screen
for x in range(15):
self.buttons.append(Button())
self.ids.grid_1.add_widget(self.buttons[x])
self.buttons[x].background_normal = 'YOUTUBE.png'
self.buttons[x].background_down = 'opacity.png'
self.buttons[x].bind(on_release=partial(self.HoldButtonNum, x))
# Make the button switch screens to input from calling the function above
if edit_mode is True:
self.buttons[x].bind(on_release=partial(self.SwitchScreenInput, x))
def ChangePic(self, *args):
_finish_init().buttons[1].background_normal = 'folder.png'
當ChangePic叫我的錯誤:
NameError: name '_finish_init' is not defined
有什麼建議?
當使用self._finish_init(DT = 1).buttons [1] .background_normal = 'folder.png' 我我得到:「AttributeError:'NoneType'對象沒有屬性'按鈕'」 – John
'_finish_init()'函數返回'None'。看看這個函數,我沒有看到任何返回語句。 – pypypy
