如何获取复选框的值?我正在使用age.text获取年龄文本框的值,但是我不知道复选框的值吗?
当单击确定"时,然后单击如何获取选定的复选框"值并传递root.insert_data.
How to get value of checkbox?I am getting value of age textbox using age.text but checkbox value i don't know?
When click on 'Ok' then How to get selected checkbox value and pass in root.insert_data.
推荐答案
您可以使用其active
属性获取复选框的选中状态,因此请尝试更改:
You can get the checked state of a checkbox with its active
property, so try change:
GreenButton:
text: 'Ok'
on_press: root.insert_data(chk.active ,age.text)
在此代码段中,chk.text
更改为chk.active
,对我来说正常工作.
In this snippet chk.text
was changed to chk.active
which works for me properly.
在 https://kivy.org/docs上查看有关kivy复选框的更多参考/api-kivy.uix.checkbox.html
希望它会有所帮助.试试看.
Hope it helps. Give it a try.
因此,为了能够获取每个复选框的属性和文本输入,可以将ObjectProperties
分配给小部件,并将它们链接到test.py
文件.
So in order to be able to get the properties of each checkbox and the text input you can assign ObjectProperties
to the widgets, and you can link them to your test.py
file.
修改后的来源:
from kivy.uix.screenmanager import Screen
from kivy.app import App
from kivy.lang import Builder
from kivy.core.window import Window
from kivy.properties import ObjectProperty
Window.size = (600, 325)
class UserGroup(Screen):
male = ObjectProperty(None)
female = ObjectProperty(None)
age = ObjectProperty(None)
def insert_data(self):
if self.male.active:
print('Male')
elif self.female.active:
print('Female')
else:
print('No gender selected')
print(self.age.text)
class FactUserGroup(App):
def build(self):
self.root = Builder.load_file('test.kv')
return self.root
if __name__ == '__main__':
FactUserGroup().run()
在.py
文件中,您可以找到ObjectProperty
的新导入.
您还可以看到在UserGroup
中定义了三个新属性来与视图交互,并且在UserGroup.insert_data
中的修改很简单.
In the .py
file you can find a new import of ObjectProperty
.
Also you can see that three new properties were defined in UserGroup
to interact with the view, and the modifications in UserGroup.insert_data
are straightforward.
<CustomLabel@Label>:
text_size: self.size
valign: "middle"
padding_x: 5
<SingleLineTextInput@TextInput>:
multiline: False
<GreenButton@Button>:
background_color: 1, 1, 1, 1
size_hint_y: None
height: self.parent.height * 0.120
UserGroup
male: chk_male
female: chk_female
age: txt_age
GridLayout:
cols: 2
padding : 30,30
spacing: 20, 20
row_default_height: '30dp'
Label:
text: 'Male'
text_size: self.size
valign: 'middle'
CheckBox:
group: 'check'
id : chk_male
Label:
text: 'Female'
text_size: self.size
valign: 'middle'
CheckBox:
group: 'check'
id: chk_female
CustomLabel:
text: 'age'
text_size: self.size
valign: 'middle'
SingleLineTextInput:
id: txt_age
GreenButton:
text: 'Ok'
on_press: root.insert_data()
GreenButton:
text: 'Cancel'
on_press: app.stop()
在.kv
文件中,两个复选框的ID和文本输入分别重命名为chk_male
,chk_female
和txt_age
.
In the .kv
file the ids of the two checkboxes and the text input are renamed to chk_male
, chk_female
and txt_age
respectively.
您还可以看到在UserGroup
部分的开头定义了对象属性链接.
Also you can see that the object property links are defined at the beginning of the UserGroup
section.
希望这很有意义并符合您的要求.
Hope it makes sense and match your requirements.
