Hi,

It’s hard to say without seeing the code. Does the debug version print something as debug message? This typically happens if a signal/slot connect call fails (which could be a reason).
Did you implement the slot? Did you implement it in the correct class? Did you call connect or setupUI?

Hi, usually when a slot isn’t called it is because the connect wasn’t correct. In QDesigner you are able the check the signal/slot editor. Might want to debug it with just a simple lineedit update next to it. If that works, the signal is issued. After that make sure you are able to call the desired slot (maybe private member of a different class?)
good luck, but as Gerolf says, we can’t do much without code.

Thank you it works!!!! sorry it’s my fault, public slot: instead of public: in my .h even if you added the functions manually by right clicking on the form and selecting change signals/slots:
thank you for your help!
