change the size of a widget

[EL-jos]

greetings to everyone,
I have a problem that I can't solve, here's the problem: I have a widget(container) that contains a label to display the text but I want to make the size of the widget(container) vary according to the number of characters in the label

@mrjj Thank you for your answer but except that the code provided in the link you gave me just varies the size of the widget vertically but I want the size of the widget to vary vertically and also horizontally.

Thank you in advance.

@EL-jos
ok, did u try with 2x QSizePolicy::MinimumExpanding ?

@mrjj still nothing the size does not vary horizontally
Here's my code maybe I misspelled it:

QVBoxLayout *layout = new QVBoxLayout;
layout->setSizeConstraint(QLayout::SetMinimumSize);
this->setLayout(layout);
for(int i = 0; i < 5; i++)
{
    QLabel *label = new QLabel;
    label->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Minimum);
    label->setWordWrap(true);
    label->setText("This is a very long text. ");
    layout->addWidget(label);
}

I even reduced the number of characters to see if it works.

Can someone help me, please?

@EL-jos
did you try with
label->setSizePolicy( QSizePolicy::MinimumExpanding, QSizePolicy::MinimumExpanding);
