| Michael,
| Thank you this works and it gets me in the right direction! I appreciate the
| reply.
|
| Can you tell me how to make the class method act upon all instances of
| MyLineEdit without specifically calling out le0, le1, le2, etc.
| individually??
|

| if this is the right thing to do or not, I just learning myself......

Try something like this (solution 1):
<code>
class MyLineEdit(QLineEdit):
~    # keeps track of all instances of MyLineEdit,
~    # but is buggy if instances are removed
~    allinstances = []
~    def __init__(self, parent):
~        self.allinstances.append(self)
~        QLineEdit.__init__(self, parent)
~        self.setText("hello")

~    def set(self, txt):
~        self.setText(txt)

~    def setAll(cls, x):
~        for le in cls.allinstances:
~            le.set(x)

~    setAll=classmethod(setAll)
</code>

and then
<code>
def setLineEdit(self):
	MyLineEdit.setAll("hi")
</code>


solution 2:
<code>
def setLineEdit(self):
~    for name in self.__dict__:
~         w = getattr(self, name)
~         if isinstance(w, MyLineEdit):
~             w.set("hi")
</code>

There are certainly some more solutions, maybe this helps you finding the best one.

greetings

Torsten
