另一种方法是使用按钮组。例如:
import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
class MoodExample(QGroupBox):
def __init__(self):
super(MoodExample, self).__init__()
# Create an array of radio buttons
moods = [QRadioButton("Happy"), QRadioButton("Sad"), QRadioButton("Angry")]
# Set a radio button to be checked by default
moods[0].setChecked(True)
# Radio buttons usually are in a vertical layout
button_layout = QVBoxLayout()
# Create a button group for radio buttons
self.mood_button_group = QButtonGroup()
for i in xrange(len(moods)):
# Add each radio button to the button layout
button_layout.addWidget(moods[i])
# Add each radio button to the button group & give it an ID of i
self.mood_button_group.addButton(moods[i], i)
# Connect each radio button to a method to run when it's clicked
self.connect(moods[i], SIGNAL("clicked()"), self.radio_button_clicked)
# Set the layout of the group box to the button layout
self.setLayout(button_layout)
#Print out the ID & text of the checked radio button
def radio_button_clicked(self):
print(self.mood_button_group.checkedId())
print(self.mood_button_group.checkedButton().text())
app = QApplication(sys.argv)
mood_example = MoodExample()
mood_example.show()
sys.exit(app.exec_())

您将需要遍历组框中的所有单选按钮,并检查每个radiobox的属性isChecked()
。
例如:
radio1 = QtGui.QRadioButton("button 1")
radio2 = QtGui.QRadioButton("button 2")
radio3 = QtGui.QRadioButton("button 3")
for i in range(1,4):
buttonname = "radio" + str(i)
if buttonname.isChecked():
print buttonname + "is Checked"
供参考,请检查http://pyqt.sourceforge.net/Docs/PyQt4/qradiobutton.html

我设法通过使用索引和循环的组合来解决这个问题。
indexOfChecked = [self.ButtonGroup.buttons()[x].isChecked() for x in range(len(self.ButtonGroup.buttons()))].index(True)
答案 3 :(得分:1)
def izle(self):
radios=["radio1","radio2","radio3","radio4"]
for i in range(0,4):
selected_radio = self.ui.findChild(QtGui.QRadioButton, self.radios[i])
if selected_radio.isChecked():
print selected_radio.objectName() + "is Checked"
