如何從pybox中的groupbox中獲取已檢查的單選按鈕

Question

我有一些包含單選按鈕的groupbox。我怎樣才能知道哪一個被檢查。

Answer 1

您將需要遍歷groupbox中的所有單選按鈕，並檢查每個無線電框的屬性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" 

參考，檢查http://pyqt.sourceforge.net/Docs/PyQt4/qradiobutton.html

Answer 2

的另一種方法是使用按鈕組。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_())

Answer 3

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 4

我設法利用指數和環的組合來解決此問題。

indexOfChecked = [self.ButtonGroup.buttons()[x].isChecked() for x in range(len(self.ButtonGroup.buttons()))].index(True)
