QLineEdit does not want to expand

[peter-70]

Inside of my QGridLayout I have a QLineEdit, at the second column.
It is a toolbar, so I cut or put elements into it, at the begin of runtime.

When I have only one button in the first column, and a QLineEdit in anyone column,
then I set the SizePolicy, Stretch of the widget and so on... but nothing works!

The QLineEdit stay always in his initial size.

What I must do, to expand the QLineEdit to maximum of available place?

@peter-70 Do you have a third column?
