Hi!
Please, someone help me!

I have a QLineEdit and I want to assign a Signal (textChanged()) to do something (to lock a Table Widget) when the lineEdit is no blank.

i assigned the control textChanged() to a function which lock the table with: ui.tbPf.setEnabled(False) but when type some characters to this lineEdit, the table is not locked?

What I do wrong? I have to use other Signal?


Thank's a lot!
