[PyQt] Show QDialog and execute code after

[Starglider Developer]

Hi,
I need after the QDialog is show, to run code and display the output to a
QTextEdit.
Now I can only run the code with the QDialog with user input -a QPushButton-
If the code runs inside the
def __init__(self, parent=None):

the QDialog is not shown until it finish the code execution.

I'm using Python 2.7 and PyQt4.

Thank you in advance.
