Problems centering a QLineEdit into a VLayout

roseicollis

Hi,

I have a QWizardPAge where I have a Vertical layout (Vlay = new QVBoxLayout();) and inside it i have a label (QLabel *my_label) and then a QLineEdit (QLineEdit *le_Per;)
I add the Vertical layout to the general one like this:

    this->getLayout()->addLayout(this->Vlay);

Until here its all okey, I see the label and down of it I see the LineEdit BUT then I want the LineEdit centered on the screen, so I tried with:

Vlay->setAlignment(le_Per,Qt::Align);

But its still on the left side of the screen. I just want the lineEdit on the center, the label must be on the left side to be easy to read as it is 2 lines long of information.

I've trie d too with:

le_Per->setStyleSheet("QLineEdit{margin-left: 100px;}");

But instead of moving the all widget, it moves the start of it and not the end so the widget becomes shorter than it was so... if I try to center it with a 300px the widget (LineEdit) dissapears .

Thank you so much!

Hello,
If I understand the question correctly, hopefully I do, you could insert a spacer to left and right of the line edit. That should do the trick. Here is a quick reference: http://doc.qt.io/qt-5/qspaceritem.html

Kind regards.

@kshegunov I've see some examples but if I am right, I will need a HLayout also wich I'm trying to avoid (to minimize the quantity of widgets)

kshegunov

Yes, you will probably do. Widgets are pretty thin (resources-wise) so in most cases creating lots of them is not a problem. For your problem you might also consider a form or a grid layout, they might be a more suitable choice.

@kshegunov I've had to say that I was trying to avoid using more widgets like the HLayout . I'll consider your option about the form and the grid if I can't do it withouth adding more widgets.

Thank you so much!

@kshegunov yes yes I know how that page works, but thanks for remind me it. It doesn't really satisfy me because it's not how I want it to work but yes, it does answer my question correctly :)

@roseicollis
I don't change the page, but there is a button at the bottom Thread tools or something like this, when you click it there should be a Mark as solved option. ;)
Kind regards.
