best object creation method

[nuliknol]

Hi,
I would like to ask , which declaration of object is faster?

QLabel     lbl_name;
lbl_name.setText("Name:");

QLabel     lbl_name;
lbl_name.setText("Name:");

To copy to clipboard, switch view to plain text mode 

or this:

QLabel     *lbl_name;
lbl_name= new QLabel("Name:");

QLabel     *lbl_name;
lbl_name= new QLabel("Name:");

To copy to clipboard, switch view to plain text mode 

Or in other words, is it best to use pointers to objects or objects themselves ?
I am going to use this for creating dialogs and windows in my app.
TIA
