我如何使用age.text获取年龄文本框的价值,但我不知道复选框的价值?
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。
最佳答案
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:
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。在https://kivy.org/docs/api-kivy.uix.checkbox.html上查看有关kivy复选框的更多参考
希望能帮助到你。试试看。
更新:
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,然后可以将它们链接到test.py
文件。修改后的来源:
test.py
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,您可以找到新导入的ObjectProperty
。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
中的修改非常简单。测试文件
<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
。您还可以看到在
UserGroup
部分的开头定义了对象属性链接。希望它有意义并符合您的要求。
