关于pyqt4：如何从pyqt中的组框中获取选中的单选按钮

How to get the checked radiobutton from a groupbox in pyqt

我有一个带有一些单选按钮的分组框。我怎么知道哪一个是检查过的？

另一种方法是使用按钮组。例如：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
30
31
32
33
34
35
36

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_())

我在以下网站找到了更多信息：

您需要遍历GroupBox中的所有单选按钮，并检查每个RadioBox的属性isChecked()。

如：

1
2
3
4
5
6
7
8

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"
