问题描述
大家都好吗？这是我关于 StackOverflow 的第一个问题。
我正在学习 Kivy，但无法在弹出窗口中输入文本。目标是将文本放入变量中。
我的代码非常大，所以我将创建一个完全复制我的场景的基本示例。走吧。
这是我的代码.py
from Produtivese_Key_Mouse import Record_mk_pyp
from kivy.core.window import Window
from kivymd.app import MDApp
from kivymd.uix.Boxlayout import MDBoxLayout
from kivymd.uix.button import MDFlatButton
from kivymd.uix.dialog import mddialog
Window.size = (800,500)
class Class_one(MDBoxLayout):
conter = 0
def __init__(self,task=[],**kwargs):
super().__init__(**kwargs)
Class_one.add_tasks(self,task)
def add_tasks(self,task,**kwargs):
for x in task:
Class_one.conter += 1
cont = Class_one.conter
icon_left = f'{x["icon"]}'
title = f'{cont} - {x["tx1"]}'
second_title = f'{x["tx2"]}'
third_title = f'{x["tx3"]}'
self.ids.Box_one.add_widget(Join_tasks_buttons(icon=icon_left,tx1=title,tx2=second_title,tx3=third_title)
)
def callback_one(self,instance):
if instance.icon == 'format-text':
self.dialog = None
Class_one.popup_insert_text(self)
if instance.icon == 'language-rust':
my_data = [{'icon': 'language-python','tx1': 'Python','tx2': 'Hello','tx3': 'World'}]
Class_one.add_tasks(self,my_data)
def popup_insert_text(self,**kwargs):
out_button = MDFlatButton(text='Go out',on_release=self.close_popup)
send_button = MDFlatButton(text='Submit',on_release=self.send_text)
if not self.dialog:
self.dialog = mddialog(title='Thanks for helping',type="custom",content_cls=My_text(),buttons=[out_button,send_button]
)
self.dialog.open()
# Here is my problem,I can't put the typed text in the variable (Where_is_the_text)
def send_text(self,text,**kwargs):
Where_is_the_text = My_text().ids.texto_inserido.text
print(f'o texto é: {Where_is_the_text}')
def close_popup(self,obj):
self.dialog.dismiss()
class Join_tasks_buttons(MDBoxLayout):
def __init__(self,icon='',tx1='',tx2='',tx3='',**kwargs):
super().__init__(**kwargs)
self.ids.evento_icone.icon = icon
self.ids.evento_texto_title.text = tx1
self.ids.evento_texto_second.text = tx2
self.ids.evento_texto_third.text = tx3
class My_text(MDBoxLayout):
pass
class TestApp(MDApp):
def build(self):
self.theme_cls.primary_palette = 'Blue'
self.theme_cls.primary_hue = '300'
self.theme_cls.theme_style = 'Light'
return Class_one([{'icon': 'language-python','tx3': 'World'}])
if __name__ == '__main__':
TestApp().run()
