Hi,

I have another problem:
When I change the application using the mouse or Alt+Tab:
The QLineEdit let's me introduce a code. This code is used as index to get information from a QList. If I have no text on the QLineEdit and change the application, the QLineEdit emits a finishEdit signal that tries to index the QList, and as it don't find the code, I make a QMessageBox that show that the "Code introduced" is not valid. This QMessageBox is showed many times until the application hangs.

I use this approach because I want a step by step application(without QWizard), that the first step is to get the information indexed by the code introduced.

Thanks,
