How to set de maximum width of a QGridLayout?

Hi all,

I am thinking in a QGridLayout with 4 QLineEdit horizontaly positioned, but I want the total size of the QGridLayout to be limited to 100, for example.

Is that possible?

I see the following, but do not understand how to deal with it.

Code:

---

quaternionLayout->setSizeConstraint(QLayout::SetMaximumSize());

---

Thanks in advance.

Place the layout in the widget and set the maximum width for the widget to 100. However this is usually a bad idea to constrain widget sizes this way.
