>From the docs for QObject::findChildren

QList<T> QObject::findChildren ( const QString & name = QString() ) const
Returns all children of this object with the given name that can be
cast to type T, or an empty list if there are no such objects. An
empty string matches all object names. The search is performed

Here's what I tried with an empty string to get all of the objects

Traceback (most recent call last):
  File "<string>", line 1, in <string>
TypeError: argument 1 of QObject.findChildren() has an invalid type

Out of desperation, I also tried

all with the same result.

So are the docs wrong regarding an empty string, am I doing it wrong,
or is there a bug?

findChild() has the same problem- regarding passing an empty string.

Perhaps the docs mean to state an empty QString??????


 returned all of the QCheckBox objects, so I can now iterate over
them, but I would like to understand if it really is possible to get
all the children objects with just one call, especially if the
children are different types.
