Label.setMarkup

Parses str which is marked up with the [Pango text markup language]PangoMarkupFormat, setting the label’s text and attribute list based on the parse results.

If the str is external data, you may need to escape it with g_markup_escape_text() or g_markup_printf_escaped():

GtkWidget *label = gtk_label_new (NULL);
const char *str = "some text";
const char *format = "<span style=\"italic\">\`s`</span>";
char *markup;

markup = g_markup_printf_escaped (format, str);
gtk_label_set_markup (GTK_LABEL (label), markup);
g_free (markup);

This function will set the use-markup property to TRUE as a side effect.

If you set the label contents using the label property you should also ensure that you set the use-markup property accordingly.

Parameters

str string: a markup string (see [Pango markup format]PangoMarkupFormat)
