Adding line in layout.

[Niamita]

Hi

I am trying to add line in a layout through coding, but i do not find name of line class.I am trying to add line which are present in qt designer toolbox.
please tell me how to add them in a layout.
One more thing when i am adding space in a gridlayout , it does not effect anything in display.
My code for adding space is

QSpacerItem *spacerItem = new QSpacerItem(300, 20, QSizePolicy::Expanding);
grid->addItem(spacerItem, 4, 0, 4, 1);

QSpacerItem *spacerItem = new QSpacerItem(300, 20, QSizePolicy::Expanding);
grid->addItem(spacerItem, 4, 0, 4, 1);

To copy to clipboard, switch view to plain text mode 

Actually i want to leave first column of layout blank.

Actually i want to leave first column of layout blank.

Then just don't add anything there and it will be blank.

i do the same but second column widget stretch in first and second column.

Should any line in first column contain something that is not empty? If not, what is the point in having the empty space in the first place?

I have gridlayout which i want to set in window after leaving some gap from left of the window(like first column in whole layput does not contain any widget).

Ok, but my question is why you want to leave the gap. You can do that using the spacer code you posted if you use the Minimum size policy however that's probably not the best solution.
