英文:
Python & qtDesigner uic pop-up window lineEdit access
问题
I'm newbie.
I want to click a pushButton to open a new window and take text from main window lineEdit and copy to new pop-up window lineEdit.
So far I can create a new window but can't access lineEdit. No errors, the app is not responding.
This is what I have:
from PyQt5.QtWidgets import QApplication
from PyQt5 import uic
app = QApplication([]) # 主窗口
ui = uic.loadUi(r"D:\UI_test\gui\main_gui_TT.ui")
appedit = QApplication([]) # 弹出窗口
uiedit = uic.loadUi(r"D:\UI_test\gui\input_TT.ui")
def edit1():
uiedit.show()
appedit.exec_()
uiedit.lineEdit_CC.setText('text') # <- 这一行有问题
ui.pushButton_1edit.pressed.connect(edit1)
ui.show()
app.exec_()
Please help what is wrong here?

你应该只有一个 QApplication，即使有多个窗口，考虑到上述问题，解决方案如下：
from PyQt5.QtWidgets import QApplication
from PyQt5 import uic
app = QApplication([]) # 主窗口
ui = uic.loadUi(r"D:\UI_test\gui\main_gui_TT.ui")
uiedit = uic.loadUi(r"D:\UI_test\gui\input_TT.ui")
def edit1():
uiedit.show()
uiedit.lineEdit_CC.setText("文本")
ui.pushButton_1edit.pressed.connect(edit1)
ui.show()
app.exec_()
英文:
You should only have a single QApplication even if you have many windows, considering the above the solution is:
from PyQt5.QtWidgets import QApplication
from PyQt5 import uic
app = QApplication([]) # Main Window
ui = uic.loadUi(r"D:\UI_test\gui\main_gui_TT.ui")
uiedit = uic.loadUi(r"D:\UI_test\gui\input_TT.ui")
def edit1():
uiedit.show()
uiedit.lineEdit_CC.setText("text")
ui.pushButton_1edit.pressed.connect(edit1)
ui.show()
app.exec_()
