I have designed an UI with Qt but I am facing an issue. In my UI I use two QLineEdit for IP addresses. They have a fixed width using setFixedWidth.

When the childWidget that contains them is set on top with parentLayout->setAlignment(&childWidget, Qt::AlignTop) I get the correct width of QLineEdit :

But when childWidget is vertically centered and on the left with:
parentLayout->setAlignment(&childWidget, Qt::AlignVCenter | Qt::AlignLeft)
I get a smaller width of QLineEdit:

I don't understand why the QLineEdit have a smaller width when the childWidget is on the left, their width should be the same, as it's fixed.

What is size policy of your line editors? – Dmitry Sazonov May 24 '18 at 13:20
Their size policy is Fixed – Laurent Mesguen May 24 '18 at 13:26
You mentioned Parent Qwidget .. and `parentLayout`, but its not clear what is `parentLayout` ? how it relates to other elements? you could make things clear just sharing your .ui design file – Mohammad Kanan May 24 '18 at 20:27
Indeed it's the parent QLayout not the QWidget, I have updated the picture – Laurent Mesguen May 25 '18 at 07:22
Only if you share .ui file, things might be clear – Mohammad Kanan May 25 '18 at 22:16
