What does this mean in the project file.

Hi all I just have a quick query really.

What does

QT       += core gui

QT       += core gui

To copy to clipboard, switch view to plain text mode 

mean in the project file?

Thanks for your time and trouble

It means your app will be linked against QtCore and QtGui libraries.

Hi thanks very much for that.

Could you perhaps tell me what this means?

Ui::LoginWindow *ui;

Ui::LoginWindow *ui;

To copy to clipboard, switch view to plain text mode 

Is it creating a pointer to the ui namespace or something??

Confused

No, it creates a pointer to a LoginWindow class instance, and class LoginWindow is defined in the Ui namespace.

The uic provides an alternative name for the same class: ui_LoghinWindow.
Take a look here if you need more information on different ways to use the ui file in your C++ code.
