Qt - iterating through QRadioButtons

Question

I have a group project for school that I am working on. A member of my group has created a window that has ~75 radio buttons. I want to force all of them to be "clear" or "unchecked" on a button press.

Does anyone know a good way to go about doing this? I have been looking into QObjectList but I can't simply do QObjectList *children = new QObjectList(ui->groupBox->children()); and loop them using a for loop as QObjectList does not appear to have a next method..

I have also tried to do something like

QObjectList *children = new QObjectList(ui->groupBox->children());
for(QObject *iterator = children.first(); iterator!=NULL; children.pop_front()){
    iterator = children.first();
    iterator->at(0)->setCheckabled(false);
}

But because iterator is a QObject, setCheckable does not exist like on a radio button.

Thoughts/hints would be appreciated.

Edit: I'll even take a hint on a way to iterate through variables with similar names. For instance, all of my radiobuttons are named RadioButton_1, RadioButton_2, etc.

Answer 1

Use a QButtonGroup, set it to exclusive (then only one radiobutton will be checked at a time). It also gives you the currently checked button, in case you want to uncheck it, too. (to have no checked buttons at all).

Also note that what you probably want to modify is the "checked" property, not "checkable" (where false means that the button can't be checked/unchecked at all).
