[Qt-interest] Is there a better way to code this to prevent recursive calling?

[Alexandre Beraud]

Hi,

An ugly (but efficient) way of preventing it from calling itself is with 
QObject::blockSignals(bool) before and after the call to setValue() 
(argument true before, and false after).
Regards,

Alex
