Hi,
After sinuous ways I found a solution that work. It's not still
clear in my mind but it works.
I had to add 'self.cleanButton.setAutoDefault(False)' because adding
a 'self.cleanButton.setDefault(False)' does not work.
As the Qt assistant said, it depends of the GUI style .... A beat
tedious, no ?
Although i receive no answer to my question, some questions came to me:
Was my question too evident ?
Too few people are reading this mailing-list ?
Were my sentences not very well express ?
No luck ?
Cheers, Simon.

Objet : Use QTextEdit() clear slot
Hi All,
It seems that "cleanButton connect" stop to a new expression
evaluation in the following code ?
1/ If you comment this connection the program works again !!
2/ If you "reset" with the "cleanButton" something you wrote in the
QTextEdit, it cleans it !!
Any track ?
Simon
