Add QLineEdit in widget

[stbb24]

Is this the proper way of adding a line edit in a widget?

QLineEdit *lineEdit = new QLineEdit;
layout->addWidget(linEdit);

QLineEdit *lineEdit = new QLineEdit;
layout->addWidget(linEdit);

To copy to clipboard, switch view to plain text mode 

I'm a total qt newbie and finding it hard to understand the documentation

I'm using sublime text as my text editor and compiling and running the program using the terminal
