Question

代码的基本布局

在这里，每当用户单击PushButton 'Press me'时，都会生成一个新的CheckBox。

from PyQt5 import QtWidgets, QtGui, QtCore

count = 1

class Window(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        self.vlayout = QtWidgets.QVBoxLayout()
        self.pushButton1 = QtWidgets.QPushButton("Press me", self)
        self.pushButton1.clicked.connect(self.addCheckbox(count))
        self.pushButton2 = QtWidgets.QPushButton("OK", self)
        self.vlayout.addWidget(self.pushButton1)
        self.vlayout.addWidget(self.pushButton2)

        self.setLayout(self.vlayout)

    def addCheckbox(self,count):
        global count
        self.vlayout.addWidget(str(count),QtWidgets.QCheckBox())
        count = count +1 

application = QtWidgets.QApplication(sys.argv)
window = Window()
window.setWindowTitle('Hello')
window.resize(250, 180)
window.show()
sys.exit(application.exec_())

我想做什么？

现在您将拥有唯一的复选框，每个复选框具有不同的编号，我想添加更多功能。

每次用户选择特定的复选框时，我想知道用户单击PushButton OK后单击了哪个复选框。例如：我点击复选框1-> OK-> print 1 on the screen

我该怎么做？

PS：我们需要考虑用户永远不会点击Press me的可能性，因此不会生成任何折叠框，并且会直接点击OK

只需使用列表来存储QCheckBox，然后通过迭代进行验证。

PyQt5：检查动态创建的复选框的存在并引用它们
