Question

我正在使用两个c ++二维数组A1和A2。可以说，A1应该代表初始状态，而A1 = A2（就在第一轮！）。接下来，我要使用A1保存旧状态，并使用A2保存计算机的当前状态。

我的问题是： -如何覆盖A2的值？ -完成一回合后，如何用A2的状态覆盖A1的状态。

我以前的尝试：我只是使用了这些值。

gridOptions

问题是，A2中没有应用任何更改。

您可以使用memcpy将一个数组复制到另一个数组：

import sys

class Pencere (QWidget):
    def __init__(self):
        super().__init__()
        self.init_ui()

    def init_ui(self):
        self.liste = QListWidget()
        self.liste.insertItem(2, "PAGE 1")
        self.stackedwidget = QStackedWidget()
        self.w3 = QWidget()
        self.w3lay()
        self.stackedwidget.addWidget(self.w3)
        hbox = QHBoxLayout()
        hbox.addWidget(self.liste)
        hbox.addWidget(self.stackedwidget)
        self.setLayout(hbox)
        self.liste.currentRowChanged.connect(self.uygula)
        self.setWindowTitle("TITLE")
        self.show()

        self.butonn.clicked.connect(lambda: self.click34(self.checkbox1.isChecked(), self.checkbox2.isChecked(), self.checkbox3.isChecked(), self.yazi_alani, self.deneme, self.yazi_alani2, self.yazi_alani3, self.deneme3))
        self.w3.setLayout(self.h_box)


    def click34(self, checkbox1, checkbox2, checkbox3, yazi_alani, deneme, yazi_alani2, yazi_alani3, deneme3):
        if checkbox1 and not checkbox2 and not checkbox3:
            deneme3.addWidget(QLabel("ABC"))
            yazi_alani2.setText("-----------------------")
            yazi_alani.setText("DEF")
            yazi_alani3.setText("-----------------------")
            deneme.addWidget(QLabel("ABC"))
            deneme.addWidget(QLineEdit())


        elif checkbox2 and not checkbox1 and not checkbox3:
            yazi_alani2.setText("----------------------------")
            yazi_alani.setText("ABC")
            yazi_alani3.setText("----------------------------")

            deneme.addWidget(QLabel("ABC"))
            deneme.addWidget(QLineEdit())

app = QApplication(sys.argv)
pencere = Pencere()
sys.exit(app.exec_())

使用两个数组时进行statetransition
