문제 설명
사용자 지정 대화 상자 PyQT5를 닫고 데이터 가져오기 (Close and get data from a custom dialog PyQT5)
Qt Designer에서 만든 사용자 정의 대화 상자를 사용할 수 없습니다. 대화 상자를 팝업할 수 있는 방법을 알고 있지만 해당 줄 텍스트에서 데이터를 가져올 수 없습니다.

이 프로그램에 문제가 있습니다.
취소를 클릭하여 대화 상자만 종료하면 메인 프로그램. (저는 self.close, self.hide로 시도했습니다...)
line_text에 링크를 추가하고 해당 링크를 메인 프로그램으로 가져오고 싶지만, 추가를 클릭하여 대화 상자를 닫고 데이터를 기본 프로그램으로 전달합니다.
대화 상자를 호출하는 방법은 괜찮습니까?
def open_dialog(self): dialog = QtWidgets.QDialog() dialog.ui = Form() dialog.ui.setupUi(dialog) dialog.exec_() dialog.show()
감사합니다. 내가 어떻게 이것을 할 수 있는지 이해가되지 않습니다. 누군가가 도울 수 있기를 바랍니다. 다시 한 번 감사드립니다.

방법 1:
You need to exec_() to do this and Here is a minimal version of your code which is fixed from PyQt4 import QtCore, QtGui import sys
class PopUpDLG(QtGui.QDialog):
def __init__(self):
super(PopUpDLG, self).__init__()
self.setObjectName("self")
self.resize(200, 71)
self.setMinimumSize(QtCore.QSize(200, 71))
self.setMaximumSize(QtCore.QSize(200, 71))
self.setContextMenuPolicy(QtCore.Qt.NoContextMenu)
icon = QtGui.QIcon()
icon.addPixmap(QtGui.QPixmap("Icons/Plus‑32.png"), QtGui.QIcon.Normal, QtGui.QIcon.Off)
self.setWindowIcon(icon)
self.gridLayout = QtGui.QGridLayout(self)
self.gridLayout.setObjectName("gridLayout")
self.text_link = QtGui.QLineEdit(self)
self.text_link.setObjectName("text_link")
self.gridLayout.addWidget(self.text_link, 0, 0, 1, 2)
self.add_link = QtGui.QPushButton(self)
self.add_link.setObjectName("add_link")
self.gridLayout.addWidget(self.add_link, 1, 0, 1, 1)
self.cancel_link = QtGui.QPushButton(self)
self.cancel_link.setObjectName("cancel_link")
self.gridLayout.addWidget(self.cancel_link, 1, 1, 1, 1)
self.retranslateUi(self)
self.cancel_link.clicked.connect(self.reject)
self.add_link.clicked.connect(self.get_link)
self.retrunVal = None
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
self.setWindowTitle(_translate("Dialog", "Add link"))
self.add_link.setText(_translate("Dialog", "Add"))
self.cancel_link.setText(_translate("Dialog", "Cancel"))
def get_link(self):
self.retrunVal = self.text_link.text()
self.accept()
def exec_(self):
super(PopUpDLG, self).exec_()
return self.retrunVal
class MainDialog(QtGui.QMainWindow):
def __init__(self):
