如何在 2 个 QListWidget 之间交换多个项目？

Question

我有一个新问题要问你。我有 2 个包含许多项目的 QListWidget。我想要 select 很多项目，单击一个按钮，然后在第二个 QListWidget 中单击 cut/paste，反之亦然。

有人知道我该怎么做吗？？？

这是我发展的开始：

from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
    MainWindow.setObjectName("MainWindow")
    MainWindow.resize(816, 603)
    self.centralwidget = QtWidgets.QWidget(MainWindow)
    self.centralwidget.setObjectName("centralwidget")
    self.listWidget1 = QtWidgets.QListWidget(MainWindow)
    self.listWidget1.setGeometry(QtCore.QRect(370, 120, 151, 311))
    self.listWidget1.setObjectName("listWidget1")
    self.listWidget1.setSelectionMode(QtWidgets.QAbstractItemView.MultiSelection)
    item = QtWidgets.QListWidgetItem()
    self.listWidget1.addItem(item)
    item = QtWidgets.QListWidgetItem()
    self.listWidget1.addItem(item)
    self.listWidget_2 = QtWidgets.QListWidget(MainWindow)
    self.listWidget_2.setGeometry(QtCore.QRect(600, 120, 151, 311))
    self.listWidget_2.setObjectName("listWidget_2")
    self.listWidget_2.setSelectionMode(QtWidgets.QAbstractItemView.MultiSelection)
    self.pushButton_3 = QtWidgets.QPushButton(MainWindow)
    self.pushButton_3.setGeometry(QtCore.QRect(540, 220, 51, 21))
    self.pushButton_3.setObjectName("pushButton_3")
    self.pushButton_4 = QtWidgets.QPushButton(MainWindow)
    self.pushButton_4.setGeometry(QtCore.QRect(540, 270, 51, 21))
    self.pushButton_4.setObjectName("pushButton_4")
    self.retranslateUi(MainWindow)
    QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
    _translate = QtCore.QCoreApplication.translate
    MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
    __sortingEnabled = self.listWidget1.isSortingEnabled()
    self.listWidget1.setSortingEnabled(False)
    item = self.listWidget1.item(0)
    item.setText(_translate("MainWindow", "test1"))
    item = self.listWidget1.item(1)
    item.setText(_translate("MainWindow", "test2"))
    self.listWidget1.setSortingEnabled(__sortingEnabled)
    self.pushButton_3.setText(_translate("MainWindow", "-->"))
    self.pushButton_4.setText(_translate("MainWindow", "<--"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())

Answer 1

我刚找到答案。如果有一天有人遇到同样的问题，我会把结果放在这里。

当我点击按钮并使用 3 个功能时，我创建了一个新功能： - selectedIndexes - takeItem（从第一个 QListWidget 中删除） - addItem（在第二个 QListWidget 中添加项目）

def click_pushButton(self):
# sort rows in descending order in order to compensate shifting due to takeItem

    rows = sorted([index.row() for index in self.listWidget1.selectedIndexes()],
              reverse=True)
    print('AAA')
    for row in rows:
        # assuming the other listWidget is called listWidget_2
        self.listWidget_2.addItem(self.listWidget1.takeItem(row))

如何在 2 个 QListWidget 之间交换多个项目？
