我用 kivy python 创建了一个日历，带有一个微调下拉小部件，可以计算当天的工作小时数。我遇到的问题是我无法将字体设置为 30。我尝试过在网上找到的无知的示例和描述，但都不起作用。 这是罪人：
def show_osark_dialog(self): # 为 OSARK 创建一个弹出窗口 osark_popup = 弹出窗口(title='Matematik', size_hint=(无, 无), size=(700, 400), auto_dismiss=True)
# Content layout for the popup
osark_content = GridLayout(cols=1, padding=10, spacing=10)
# Create spinners for selecting times
time_spinner1 = Spinner(text='00:00', values=[f'{h:02d}:{m:02d}' for h in range(24) for m in range(0, 60, 15)])
time_spinner2 = Spinner(text='00:00', values=[f'{h:02d}:{m:02d}' for h in range(24) for m in range(0, 60, 15)])
# Function to calculate time difference
def calculate_time_difference(instance, value):
time1 = datetime.strptime(time_spinner1.text, '%H:%M')
time2 = datetime.strptime(time_spinner2.text, '%H:%M')
time_diff = abs(time2 - time1)
osark_label.text = f'Jobbade timmar: {time_diff}'
# Bind the calculate_time_difference function to spinner values change
time_spinner1.bind(text=calculate_time_difference)
time_spinner2.bind(text=calculate_time_difference)
# Label to display the time difference
osark_label = Label(text='Välj start och sluttid ...')
# Add spinners and label to the content layout
osark_content.add_widget(time_spinner1)
osark_content.add_widget(time_spinner2)
osark_content.add_widget(osark_label)
# Set the content of the popup window
osark_popup.content = osark_content
# Open the popup window
osark_popup.open()
如何在此下拉小部件中获取字体 30？
SpinnerSpinnerOptionoption_cls例如，这是一个选项类别的可能性：
class MySpinnerOption(Button):
def __init__(self, **kwargs):
super(MySpinnerOption, self).__init__(**kwargs)
self.font_size = 30
self.size_hint_y = None
self.height = 30
然后您可以在创建
Spinnertime_spinner1 = Spinner(text='00:00', values=[f'{h:02d}:{m:02d}' for h in range(24) for m in range(0, 60, 15)], option_cls='MySpinnerOption')
如果您希望
Spinnerfont_size=30Spinner谢谢您的回答。 我查看了您的代码并尝试实现它，但只是出现错误。我是一个初学者，刚刚开始使用这个代码库，所以我很难调试我不理解的代码。但是如果你看看我上面的代码，在这种情况下你会如何实现你的代码？.
如果您看到我的整个代码，可能会更容易：
