如果相同的项目在指定列表中，如何使Qlistwidgetitems自动检查？

问题描述

下面是示例代码：

from PyQt5 import QtCore,QtGui,QtWidgets

class Ui_MainWindow(object):
    def setupUi(self,MainWindow):
        MainWindow.setobjectName("MainWindow")
        MainWindow.resize(394,356)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setobjectName("centralwidget")
        self.listWidget = QtWidgets.QListWidget(self.centralwidget)
        self.listWidget.setGeometry(QtCore.QRect(60,30,241,192))
        self.listWidget.setobjectName("listWidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(130,250,75,23))
        self.pushButton.setobjectName("pushButton")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0,394,21))
        self.menubar.setobjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setobjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

        players = ["Player 1","Player 2","Player 3","Player 4"]

        for i in players:
            item = QtWidgets.QListWidgetItem(i)
            item.setFlags(item.flags() | QtCore.Qt.ItemIsUserCheckable)
            item.setCheckState(QtCore.Qt.Unchecked)
            self.listWidget.addItem(item)

        self.selected_list = ["Player 1","Player 4"]

        self.pushButton.clicked.connect(self.find_the_list)

    def retranslateUi(self,MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setwindowTitle(_translate("MainWindow","MainWindow"))
        self.pushButton.setText(_translate("MainWindow","PushButton"))

    def find_the_list(self):
        print("OKAY")
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_())

players = ["Player 1","Player 4"]列表已作为UserCheckable添加到QListWidgetItem中。第二个列表self.selected_list = ["Player 1","Player 4"]有两个项目，第二个列表是可变的。现在，如果第二个列表具有匹配项，我想检查QlistWidgetitems框。

解决方法

您可以执行以下操作：

def find_the_list(self):
    for i in range(self.listWidget.count()):
        item = self.listWidget.item(i)
        if item.text() in self.selected_list:
            item.setCheckState(QtCore.Qt.Checked)
        else:
            item.setCheckState(QtCore.Qt.Unchecked)
