Segmentation error! Please help!!!

[nix]

In your C++ instead of

QLineEdit *m_addressBD=new QLineEdit;

QLineEdit *m_addressBD=new QLineEdit;

To copy to clipboard, switch view to plain text mode 

Do

m_addressBD=new QLineEdit();

m_addressBD=new QLineEdit();

To copy to clipboard, switch view to plain text mode 

Do this for all widgets, you are redeclaring locally your variable in the constructor, so in your slot m_addressBD is null and you programm crash.

Hi all. I'm sorry but even if I don't have the segmentation error any more, the code seems to not work. I cannot connect to the MysQL database (installed on the same computer) after clicking on connect. There is always the error message Box. I don't know if the app even try to connect to database.
Can someone help me?
