Gtk.Label.set_markup

### Method

# Gtk Labelset_markup

#### Declaration [src]

    void
    gtk_label_set_markup (
      GtkLabel* self,
      const char* str
    )

#### Description [src]

Sets the labels text and attributes from markup.

The string must be marked up with Pango markup (see `pango_parse_markup()`).

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

    GtkWidget *self = gtk_label_new (NULL);
    const char *str = "...";
    const char *format = "<span style=\"italic\">\%s</span>";
    char *markup;

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

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

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

#### Parameters

`str`

  Type: `const char*`

  A markup string.

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.
