CheckBox Pyqt5 中的多个选项

  • 772

checkbox如果使用它们的分组，如何选择几个QButtonGroup 

import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *


class App(QWidget):

    def __init__(self):
        super().__init__()
        self.title = 'Тест'
        self.resize(400, 400)

        self.setFont(QFont('Times', 13))
        layout =QVBoxLayout()
        radiobox = QCheckBox('Ответ 1',self)
        radiobox2 = QCheckBox('Ответ 2', self)
        self.button_group = QButtonGroup()
        self.button_group.addButton(radiobox, 1)
        self.button_group.addButton(radiobox2, 2)
        self.button_group.buttonClicked.connect(self.selectedchoice)
        layout.addSpacing(20)
        layout.addWidget(radiobox)
        layout.addSpacing(20)
        layout.addWidget(radiobox2)
        layout.addStretch(1)

        self.setLayout(layout)
        self.show()

    def selectedchoice(self, butt):
        print(self.button_group.id(butt))


if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

有一个选项可以简单地为每个人checkbox做clicked.connect，但在我看来，你可以根据id方式和方式以某种方式做到这一点。QButtonGroup

import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *


class App(QWidget):

    def __init__(self):
        super().__init__()
        self.title = 'Тест'
        self.resize(400, 400)

        self.setFont(QFont('Times', 13))
        layout =QVBoxLayout()
        self.radiobox = QCheckBox('Ответ 1',self)
        self.radiobox.clicked.connect(self.selected_choice_1)
        self.radiobox2 = QCheckBox('Ответ 2', self)
        self.radiobox2.clicked.connect(self.selected_choice_2)
        layout.addSpacing(20)
        layout.addWidget(self.radiobox)
        layout.addSpacing(20)
        layout.addWidget(self.radiobox2)
        self.setLayout(layout)
        self.show()

    def selected_choice_1(self, state):
        if state :
            print(self.radiobox.text())
    def selected_choice_2(self, state):
        if state :
            print(self.radiobox2.text())


if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())
python

    类似于QButtonGroup但附加到按钮的东西

    import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *


class App(QWidget):

    def __init__(self):
        super().__init__()
        self.title = 'Тест'
        self.resize(400, 400)
        self.setFont(QFont('Times', 13))
        layout =QVBoxLayout()
        self.radiobox = QCheckBox('Ответ 1',self)
        self.radiobox2 = QCheckBox('Ответ 2', self)
        layout.addSpacing(20)
        layout.addWidget(self.radiobox)
        layout.addSpacing(20)
        layout.addWidget(self.radiobox2)
        push = QPushButton()
        push.clicked.connect(self.selected_choice_1)
        layout.addWidget(push)
        self.setLayout(layout)
        self.show()

    def selected_choice_1(self):
        if self.radiobox.isChecked():
            print(self.radiobox.text())
        if self.radiobox2.isChecked():
            print(self.radiobox2.text())



if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())
