<font size="+1">Hi,<br>
<br>
I have a dialog based application. When the second dialog is brought
up, I need to check some settings maintained on a file as well as some
flags set in the primary dialog. I am looking for something like an
initialize event that fires when the form is first activated. Obviously
it should not be a part of the class constructor, but I see no such
available events. <br>

I would think this is a relatively common process and I am either
overlooking it, or worse, not seeing it out of coding blindness. If
some of you could take the time to give a few hints, methods, and/or
suggestions, I would be most appreciative.<br>

Hi Robert,
Not sure why you cannot do this using the constructor of the second
dialog. You may not want to use the constructor if your second dialog is
non modal, in that case it should be easily achievable using
SIGNALS/SLOTS mechanism.
However assuming your second dialog is modal and most certainly a child
of the first Dialog, you could maybe have accessors( public methods) to
the first dialog's flags which you may pass through the constructor of
the second dialog right?
Thanks,
Subramanian

I did that with the
void QWidget::showEvent ( QShowEvent * event )
together with a class variable "firstTime" which
prevents further activation of showevent (after the first call)
