我必须使用kivy在python中编写一个程序,该程序将文本输入文本框,然后将其传递给进行网页抓取的功能,然后执行很多操作,然后返回字符串数组,而数组中的最后一个元素是对数组,因此我真的很困惑并且发送了很多时间。所以我必须写两个kv文件还是一个文件?这是我简单的kivy代码作为开始。
我尝试了,但是没有用
#textInput.py
from app import *
Builder.load_file('textInput.kv')
require('1.10.0')
class MainScreen(BoxLayout):
def __init__(self):
self.super(MainScreen, self).__init__()
def btn_click(self):
name =self.BoxLayout.BoxLayout.TextInput
#the function that takes the output of the text field
get_company_name(name)
#
#
#
# here I will call the function that returns the array so how to pass the answer
# and also pass to where ? shall I use the same kv file or create another one
class Test(App):
def build(self):
self.title = 'CompanyInfoApp'
return MainScreen()
if __name__ == '__main__':
Test().run()
lbl:My_label 方向:“垂直”
# Third section title
Label:
size_hint: (1, .1)
text: 'Welcome To compnay info App'
font_size: 25
# Third section Box
BoxLayout:
Button:
text:"let's start"
on_press:root.btn_click()
size_hint: (1, .2)
padding: [180, 180, 180, 180]
BoxLayout:
Label:
pos_hint:{'x': .3, 'y': .6}
text: 'Enter the Company Name:'
text_size: self.width-20, self.height-20
TextInput:
height: self.minimum_height
pos_hint:{'x': .3, 'y': .6}
multiline: False
text: ''
答案 0 :(得分:0)
尝试给您的TextInput
小部件一个id
。然后,您可以使用TextInput
小部件来访问id
小部件的文本数据。
这是一个基本示例:
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.boxlayout import *
main_kv = """
<Main>:
orientation: 'vertical'
TextInput:
# TextInput's id
id: txtinput
text: ''
Button:
text: "print text"
on_press: root.btn_click()
"""
class Main(BoxLayout):
def btn_click(self):
name = self.ids['txtinput'].text
print(name)
class Test(App):
def build(self):
Builder.load_string(main_kv)
return Main()
Test().run()
