Use HTML text:

QString template = "<p style=\"line-height:%1%\">%2<p>";
QString targetText = template.arg(myPercentage).arg(myTex);
QLabel *l = new QLabel(targetText, this);

where myPercentage is similar to 60 - 80. You will get compressed lines in WordWrap mode

There is QLabelno line spacing property. You can change the font of the widget, which will change the height of the line, but I suspect that this is not what you want.

<html><head/><body>

<html><head/><body>
<p style="line-height:20"><span>This is the first line of the label.</span></p>
<p style="line-height:20"><span>This is the second line.</span></p>
<p style="line-height:100"><span>This is the third and final line.</span></p>
</body></html>

In this example, you can control the spacing of each row individually. I had to make the height of the last line 100 so that Qt would not cut it in half. I assume this affects how Qt calculates the height of the label as a widget.
