PyQt Collection of QLineEdit objects

Question

Is there some way in PyQt to get a collection of all QLineEdit objects?

I am trying to add a reset button that will blank out all text in all QLineEdit on a form, so I am looking for a way to loop through all QLineEdit objects rather than listing them all in my reset function that will connect to the reset button.

Thank you.

If all the line-edits have a parent, you could use:

for child in parent.findChildren(QtGui.QLineEdit):
    child.clear()

Or possibly:

for widget in qApp.allWidgets():
    if isinstance(widget, QtGui.QLineEdit):
        widget.clear()
