#include &lt;QLabel&gt;
#include &lt;AzQtComponents/Components/Widgets/Text.h&gt;

QLabel* label;

// Assuming you've created a QLabel already (either in code or via .ui file):

// To apply various styles, use one (and only one) of the following:
AzQtComponents::Text::addHeadlineStyle(label);
AzQtComponents::Text::addTitleStyle(label);
AzQtComponents::Text::addSubtitleStyle(label);
AzQtComponents::Text::addMenuStyle(label);
AzQtComponents::Text::addLabelStyle(label); // default style
AzQtComponents::Text::addParagraphStyle(label);
AzQtComponents::Text::addTooltipStyle(label);
AzQtComponents::Text::addButtonStyle(label);

// To set various colors, use one (and only one) of the following:
AzQtComponents::Text::addPrimaryStyle(label);
AzQtComponents::Text::addSecondaryStyle(label);
AzQtComponents::Text::addHighlightedStyle(label);
AzQtComponents::Text::addBlackStyle(label);

// One text style and one text color can be applied at the same time on the same label.

/*
  Note that QLabel text display has two modes: Qt::PlainText and Qt::RichText.
  By default, it auto-selects the mode based on the text. If the text has HTML in it
  then it'll use Qt::RichText.
  This matters because \n means newline in PlainText mode, but &lt;br&gt; means newline in
  RichText mode.
