Python 关闭自定义对话框PyQT5并从中获取数据

我无法使用在Qt Designer中创建的自定义对话框。我知道如何弹出对话框，但我无法从该行文本中获取数据

主程序.py

addui.py（对话框）

我对这个程序有一些问题

如果单击“取消”仅退出对话框而不是主程序。（我试着用self.close，self.hide…）

我想在该行文本上添加一个链接，并获得到主程序的链接，但当我单击“添加”关闭对话框并将数据传递到主程序时

我怎么称呼这个对话没关系吧

 def open_dialog(self):
   dialog = QtWidgets.QDialog()
   dialog.ui = Form()
   dialog.ui.setupUi(dialog)
   dialog.exec_()
   dialog.show()

谢谢。我不知道该怎么做，希望有人能帮我。 再次感谢。

要做到这一点，您需要执行函数（），这里是您的代码的最低版本，已修复 从PyQt4导入QtCore、QtGui 导入系统

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):
        super(self.__class__, self).__init__()
        centralwidget = QtGui.QWidget(self)
        self.layout = QtGui.QHBoxLayout(centralwidget)
        self.button = QtGui.QPushButton("Open")
        self.valText = QtGui.QLabel("")
        self.layout.addWidget(self.button)
        self.layout.addWidget(self.valText)
        self.setCentralWidget(centralwidget)
        self.button.clicked.connect(self.open_dialog)

    def open_dialog(self):
        dialog = PopUpDLG()
        value = dialog.exec_()
        if value:
            self.valText.setText(value)


def main():
     app = QtGui.QApplication(sys.argv)
     form = MainDialog()
     form.show()
     app.exec_()

if __name__ == '__main__':
     main()

---

dialog.exec_389;（）；打印（dialog.text\u link.text（））

。另一个问题。我现在了解了它的工作原理，但我想将ui文件与主文件分开。我开始操作对话框上的按钮，但找不到只关闭对话框的命令，可以吗？。如果不可能，我将在main all上执行。我没有得到“我找不到只关闭对话框的命令，可以吗？”，取消和按钮将只关闭对话框，对吗？我现在可以使用>>self.cancel\u link.clicked.connect（DIALOG.reject）来执行打开信号和插槽。看看这里，如果这个答案有帮助，请投票并接受为答案：）
