    Hi. Is there any way to use color/font tags (or another solution) for QTreeWidgetItem? Need to fill it with colored text in one column.
    (Sorry for my english)

      Hi

      AS @SGaist says you need to do your own drawing of that.

      Like here

      Funny enough it seems to be exactly the same use case :)

        Hi and welcome to the forums.
        Your English is fine.

        One way is to use the
        QBrush b (Qt::red);
        item->setForeground( 0 , b );

        alt text

          @mrjj thx.. I knew about that, but need something different. My trouble - paint "new" and "item" with different colors. For example "new" - red, "item" - blue.

            You are supposed to change the color as @mrjj has shown you. The fact that you wish to vary the color depending on the text in the item is for you to implement.

              Hi,

              You will need a QStyledItemDelegate and do the text painting yourself.

                  Thx you all.
                  There was hope for some built-in functionality something like setHTML... But... Ok...
                  Think this thread can be marked as resolved.

                    @DMI3Y

                    Well you could add a QLabel to the cell and use its rich text capabilities but
                    it suffers from being non-editable and poor performance if many items.

                    You will be much happier with the Delegate.
