How to get the checked radiobutton from a groupbox in pyqt - pyqt4

Question

I have a groupbox with some radiobuttons. How do I get to know which one which is checked.

Answer 1

Another way is to use button groups. For example:
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_())

Answer 2

you will need to iterate through all the radio buttons in the groupbox and check for the property isChecked() of each radiobox.
eg:
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"
for reference, check http://pyqt.sourceforge.net/Docs/PyQt4/qradiobutton.html

Answer 3

I managed to work around this problem by using a combination of index and loop.
indexOfChecked = [self.ButtonGroup.buttons()[x].isChecked() for x in range(len(self.ButtonGroup.buttons()))].index(True)

Answer 4

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"

Answer 5

you can get all chaild objects of class from desired parent. something like
class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
self.setupUi(self)
self.show()
print(self.getCheckedRbName(self.gbRadioButtonsGroup))
def getCheckedRbName(self, rbParent: QWidget) -> str:
for rb in rbParent.findChildren(QRadioButton):
if rb.isChecked():
return rb.objectName()
gives you
#> 'rbThirdOption' is checked
