问题描述
我有以下示例窗口大小的代码。我希望将所有小部件都放到名为import requests
from bs4 import BeautifulSoup
to_search = 'laptops'
url = 'https://www.flipkart.com/search?q=
{}&otracker=search&otracker1=search&marketplace=FLIPKART&as-
show=on&as=off'.format(to_search)
html_code = requests.get(url).text
soup = BeautifulSoup(html_code,'lxml')
titles = soup.findAll('div',class_='_3wU53n')
for title in titles:
print(title,end='\n')
的{{1}}中，而不是划分窗口的百分比。但是，无论我将提示放在何处或如何附加小部件，这些提示仍会应用于整个窗口。
如代码所示，对于（500，600）窗口，嵌体的大小应仅为（480，600），最接近8 x 10的尺寸。但是，提示是针对（500，600）大小呈现的：
BoxLayout如何使inlay布局的大小提示评估为from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.Boxlayout import BoxLayout
from kivy.core.window import Window
Window.size = (500,600)
class SCApp(App):
def build(self):
# Define the (relative) 8 x 10 inlay for the board.
for n in range(8,Window.width,8):
if n * 1.25 <= Window.height:
inlay_dims = (n,int(n * 1.25))
print(inlay_dims)
else:
break
inlay = BoxLayout(orientation="vertical")
inlay.size = inlay_dims
top_portion = BoxLayout(orientation="horizontal")
inlay.add_widget(top_portion)
top_portion.size_hint = (1,0.1)
top_portion.add_widget(widget=Button())
mid_portion = BoxLayout(orientation="horizontal")
inlay.add_widget(mid_portion)
mid_portion.size_hint = (1,0.8)
btm_portion = BoxLayout(orientation="horizontal")
inlay.add_widget(btm_portion)
btm_portion.size_hint = (1,0.1)
top_portion.add_widget(widget=Button())
return inlay
SCApp().run()
给出的大小？
解决方法
使用size时，通常还必须使用size_hint=(None,None)，因为size_hint将覆盖尺寸设置。因此，请尝试更换：
inlay = BoxLayout(orientation="vertical")
具有：
inlay = BoxLayout(orientation="vertical",size_hint=(None,None))
