在 QVBoxLayout 中查找选中的 QRadioButton [英] Finding checked QRadioButton among many into a QVBoxLayout

问题描述

我使用下面的代码动态创建了一组单选按钮:

I used the code below to dynamically create a group of radio buttons:

self.wPaymantType.qgbSomeSelectionGroup = QtGui.QGroupBox()
vbox = QtGui.QVBoxLayout()

for row in listOfChoices:
    radio = QtGui.QRadioButton(row)
    if bIsFirst:
        radio.setChecked(True)
        bIsFirst = False
    if len(row.name) > nMaxLen:
        nMaxLen = len(row.name)

    vbox.addWidget(radio)

self.wPaymantType.qgbSomeSelectionGroup.setLayout(vbox)

如何遍历所有单选按钮以找出选中的单选按钮?

How can I iterate through all radio buttons to find out which one is checked?

我尝试过这样的事情，但我没有从中得到任何好处:

I tried something like this, but I didn't get anything good from it:

qvbl = self.qgbSomeSelectionGroup.children()[0]

for i in range(0, qvbl.count()):
    child = qvbl.itemAt(i)
    radio = QtGui.QRadioButton(child.widget())
    if radio != None:
        if radio.isChecked():
            print "radio button num " + str(i) + " is checked"

推荐答案

我认为它不起作用的原因是你的

I believe the reason why it's not working is your

 radio = QtGui.QRadioButton(child.widget())

调用您检查复选框是否被选中的代码.我认为您要做的是将子对象类型转换为 QtGui.QRadioButton 并且在这种情况下不起作用.相反，您应该创建一个新的小部件.尝试将其更改为 smth.像这样:

call at the code where you're checking if your checkbox is checked. I think what you're trying to do is typecast the child object to QtGui.QRadioButton and it doesn't work in this case. Instead you should be creating a new widget. Try changing it to smth. like this:

    qvbl = self.qgbSomeSelectionGroup.layout()
    for i in range(0, qvbl.count()):
        widget = qvbl.itemAt(i).widget() 
        if (widget!=0) and (type(widget) is QtGui.QRadioButton):
            if widget.isChecked():
                print "radio button num " + str(i) + " is checked"

上面的代码应该遍历布局对象的子对象，检查它们的类型并打印radio button..."以防它是单选按钮并且它被选中

the code above should be iterating through child objects of the layout object, check their type and print "radio button..." in case it's radio buttong and it's checked
