获取所有用户输入/行编辑的价值

如何解决获取所有用户输入/行编辑的价值

我正在寻找一种方法来获取应用的所有用户输入/行编辑的值或文本

我正在创建一个可以同时创建多个文件夹的应用。有多个用户输入要写入文件夹的名称，这是我通过多次调用同一个函数创建的。使用这个“self.le2.text()”只会得到创建的第一个用户输入的值。

到目前为止，这是我的代码。本质上，我希望“创建文件夹”按钮从“new_folder”函数创建的所有用户输入中创建所有文件夹。现在它只得到第一个创建的值。

import sys
import os

from PySide6 import QtWidgets,QtCore,QtGui
from PySide6.QtWidgets import QApplication


class MainWindow(QtWidgets.QMainWindow):
    def __init__(self):

        super(MainWindow,self).__init__()
        #set central widget and layout
        self.setwindowTitle("Amazing Folder Generator")
        self.generalLayout = QtWidgets.QVBoxLayout()
        self.centralWidget = QtWidgets.QWidget()
        self.setCentralWidget(self.centralWidget)
        self.centralWidget.setLayout(self.generalLayout)
        self.le1 = QtWidgets.QLineEdit()

        self.file_path()

        self.button1 = QtWidgets.QPushButton("New Folder")
        self.generalLayout.addWidget(self.button1)
        self.button1.pressed.connect(self.new_folder)

        self.button2 = QtWidgets.QPushButton("Create Folders")
        self.generalLayout.addWidget(self.button2)
        self.button2.pressed.connect(self.create_files)

        self.new_folder()
        self.new_folder()
        self.new_folder()


    def file_path(self):
        self.le1 = QtWidgets.QLineEdit()
        self.le1.setFixedHeight(20)
        self.le1.setAlignment(QtCore.Qt.AlignRight)
        self.path_layout = QtWidgets.qformlayout()
        self.path_layout.addRow("Folder Path: ",self.le1)
        self.generalLayout.addLayout(self.path_layout)


    def new_folder(self):
        self.le2 = QtWidgets.QLineEdit()
        self.le2.setFixedHeight(20)
        self.le2.setAlignment(QtCore.Qt.AlignRight)
        self.path_layout = QtWidgets.qformlayout()
        filename = "File: "
        self.path_layout.addRow(filename,self.le2)
        self.generalLayout.addLayout(self.path_layout)


    def create_files(self):
        path = self.le1.text() + "\\"
        filename = self.le2.text()
        newpath = path + filename
        if not os.path.exists(newpath):
            os.makedirs(newpath)

        else:
            print("folder already exists")


def main():
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

解决方法

简单的解决方案是将 QLineEdits 存储在列表中，然后迭代以获取文本。在这种情况下，我重写了您的代码以使其更具可读性。

import sys
import os
import os.path

from PySide6 import QtWidgets,QtCore,QtGui


class MainWindow(QtWidgets.QMainWindow):
    def __init__(self,parent=None):
        super(MainWindow,self).__init__(parent)
        self.setWindowTitle("Amazing Folder Generator")

        self.folder_le = QtWidgets.QLineEdit(alignment=QtCore.Qt.AlignRight)
        self.folder_le.setFixedHeight(20)
        self.add_row_button = QtWidgets.QPushButton("New Folder")
        self.create_button = QtWidgets.QPushButton("Create Folders")
        self.files_layout = QtWidgets.QFormLayout()

        central_widget = QtWidgets.QWidget()
        self.setCentralWidget(central_widget)
        self.form_layout = QtWidgets.QFormLayout(central_widget)
        self.form_layout.addRow("Folder Path:",self.folder_le)
        self.form_layout.addRow(self.add_row_button)
        self.form_layout.addRow(self.create_button)
        self.form_layout.addRow(self.files_layout)

        self._files_le = []

        self.add_row_button.clicked.connect(self.add_row)
        self.create_button.clicked.connect(self.create_files)

        for _ in range(3):
            self.add_row()

    @property
    def folder(self):
        return self.folder_le.text()

    @property
    def filenames(self):
        return [le.text() for le in self._files_le]

    def add_row(self):
        le = QtWidgets.QLineEdit(alignment=QtCore.Qt.AlignRight)
        le.setFixedHeight(20)
        self.files_layout.addRow("File:",le)
        self._files_le.append(le)

    def create_files(self):
        for filename in self.filenames:
            newpath = os.path.join(self.folder,filename)
            if not os.path.exists(newpath):
                os.makedirs(newpath)
        else:
            print("folder already exists")


def main():
    app = QtWidgets.QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())


if __name__ == "__main__":
    main()
