将文件选择器的值设置为调用它的对话框

Question

我有一个调用对话框的操作按钮：

class MainPanelManager(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.actionLocation.triggered.connect(self.editsettings)

    def editsettings(self):
        dialog = QDialog()
        dialog.ui = Ui_Dialog()
        dialog.ui.setupUi(dialog)
        dialog.ui.pushButton.clicked.connect(self.openfile)
        dialog.exec_()


    def openfile(self):
        folder = QFileDialog.getExistingDirectory(self, 'Select Folder', 'C:/')
        # folder value must be set to dialog textedit

对话框工作并在按下按钮时打开文件选择器。选择文件夹时如何设置值。我需要将值放入 textedit

一个简单的解决方案是将 dialog 变量声明为 self 对象的属性。因此，您可以 class 在所有方法中广泛使用它。

class MainPanelManager(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.actionLocation.triggered.connect(self.editsettings)

    def editsettings(self):
        self.dialog = QDialog()
        self.dialog.ui = Ui_Dialog()
        self.dialog.ui.setupUi(dialog)
        self.dialog.ui.pushButton.clicked.connect(self.openfile)
        self.dialog.exec_()


    def openfile(self):
        folder = QFileDialog.getExistingDirectory(self, 'Select Folder', 'C:/')
        # folder value must be set to dialog textedit
        self.dialog.ui.textedit.set_text(folder)
