    Hi. I have the following QLabel, with the following text:

    Sample
    temperature
    

    This is what it looks like on my application:

    a1584353-dbf9-4fbe-b5e8-72e4d71dfc56-image.png

    I am wondering how to make the line height of QLabel smaller. I haven't found any documentation for this, somehow, despite the feature being relatively basic. Please let me know if I missed anything or if more info is required.

      @Dummie1138 The natural vertical spacing of text automatically wrapped or with deliberate line breaks is given by QFontMetrics::lineSpacing(). This figure is a function of font and size and is not adjustable out-of-the box.

      You can subclass QLabel and provide your own rendering.

        @Dummie1138 What lines do you mean?
        Or do you mean alignment and stretching?

          Is your QLabel in a layout ?

            @jsulm By "line height", I mean this:

            cbf22319-2012-434f-90bb-a9b5d257638e-image.png

            The distance between the top and the bottom.

              @mpergand Yes, my QLabel is built in the .ui files.

                This does not mean that you're using layouts. So the question from @mpergand is still not answered.
