問題描述
我在使用 Kivy 庫的 Python 應用程序中遇到問題.特別是我試圖在 TabbedPanelItem 中創建一個可滾動的元素列表，但我不知道為什么我的列表不滾動.
I'm having problems in my Python application with Kivy library. In particular I'm trying to create a scrollable list of elements in a TabbedPanelItem, but I don't know why my list doesn't scroll.
這是我的 kv 文件:
Here is my kv file:

這里是我的 .py 代碼:
And here my .py code:
__author__ = 'drakenden'
__version__ = '0.1'
import kivy
kivy.require('1.9.0') # replace with your current kivy version !
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen, FadeTransition
from kivy.properties import StringProperty, ObjectProperty,NumericProperty
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.utils import platform
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label
from kivy.uix.scrollview import ScrollView
class Tabs(ScrollView):
def __init__(self, **kwargs):
super(Tabs, self).__init__(**kwargs)
class Tabba(TabbedPanel):
pass
class SecondScreen(Screen):
pass
class ScreenManagement(ScreenManager):
pass
presentation = Builder.load_file("layout2.kv")
class MyApp(App):
def build(self):
return presentation
MyApp().run()

推薦答案
我自己也有一段時間沒用過kivy了，如果我記得很清楚的話:因為 ScrollView 中的布局應該比滾動視圖大例如 ScrollView 寬度:1000 像素，GridView 1100 像素.所以可以滾動100px
I Myself haven't used kivy for a while but if I remember exacly: Because layout within ScrollView should be BIGGER than scroll view ex ScrollView width: 1000px, GridView 1100px. So it will be possible to scroll it by 100px
