[PyQt] Fwd: Use QTextEdit() clear slot

[Simon Stockes]

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.
