## Object Hierarchy

        GObject
        ╰── GtkTextTag

## Includes

    #include <gtk/gtk.h>

## Description

You may wish to begin by reading the text widget conceptual overview which gives an overview of all the objects and data types related to the text widget and how they work together.

Tags should be in the GtkTextTagTable for a given GtkTextBuffer before using them with that buffer.

gtk_text_buffer_create_tag() is the best way to create tags. See “gtk3-demo” for numerous examples.

For each property of GtkTextTag, there is a “set” property, e.g. “font-set” corresponds to “font”. These “set” properties reflect whether a property has been set or not. They are maintained by GTK+ and you should not set them independently.

## Functions

### gtk_text_tag_new ()

    GtkTextTag *
    gtk_text_tag_new (const gchar *name);

Creates a GtkTextTag. Configure the tag using object arguments, i.e. using `g_object_set()`.

#### Parameters

name | tag name, or `NULL`. | [allow-none]

#### Returns

a new GtkTextTag

### gtk_text_tag_get_priority ()

    gint
    gtk_text_tag_get_priority (GtkTextTag *tag);

Get the tag priority.

#### Parameters

tag | a GtkTextTag |

#### Returns

The tag’s priority.

### gtk_text_tag_set_priority ()

    void
    gtk_text_tag_set_priority (GtkTextTag *tag,
                               gint priority);

Sets the priority of a GtkTextTag. Valid priorities start at 0 and go to one less than `gtk_text_tag_table_get_size()`. Each tag in a table has a unique priority; setting the priority of one tag shifts the priorities of all the other tags in the table to maintain a unique priority for each tag. Higher priority tags “win” if two tags both set the same text attribute. When adding a tag to a tag table, it will be assigned the highest priority in the table by default; so normally the precedence of a set of tags is the order in which they were added to the table, or created with `gtk_text_buffer_create_tag()`, which adds the tag to the buffer’s table automatically.

#### Parameters

tag | a GtkTextTag |
priority | the new priority |

### gtk_text_tag_event ()

    gboolean
    gtk_text_tag_event (GtkTextTag *tag,
                        GObject *event_object,
                        GdkEvent *event,
                        const GtkTextIter *iter);

Emits the “event” signal on the GtkTextTag.

#### Parameters

tag | a GtkTextTag |
event_object | object that received the event, such as a widget |
event | the event |
iter | location where the event was received |

#### Returns

result of signal emission (whether the event was handled)

### gtk_text_tag_changed ()

    void
    gtk_text_tag_changed (GtkTextTag *tag,
                          gboolean size_changed);

Emits the “tag-changed” signal on the GtkTextTagTable where the tag is included.

The signal is already emitted when setting a GtkTextTag property. This function is useful for a GtkTextTag subclass.

#### Parameters

tag | a GtkTextTag. |
size_changed | whether the change affects the GtkTextView layout. |

Since: 3.20

### gtk_text_attributes_new ()

    GtkTextAttributes *
    gtk_text_attributes_new (void);

Creates a GtkTextAttributes, which describes a set of properties on some text.

#### Returns

a new GtkTextAttributes, free with `gtk_text_attributes_unref()`.

### gtk_text_attributes_copy ()

    GtkTextAttributes *
    gtk_text_attributes_copy (GtkTextAttributes *src);

Copies `src` and returns a new GtkTextAttributes.

#### Parameters

src | a GtkTextAttributes to be copied |

#### Returns

a copy of `src` , free with `gtk_text_attributes_unref()`

### gtk_text_attributes_copy_values ()

    void
    gtk_text_attributes_copy_values (GtkTextAttributes *src,
                                     GtkTextAttributes *dest);

Copies the values from `src` to `dest` so that `dest` has the same values as `src` . Frees existing values in `dest` .

#### Parameters

src | a GtkTextAttributes |
dest | another GtkTextAttributes |

### gtk_text_attributes_unref ()

    void
    gtk_text_attributes_unref (GtkTextAttributes *values);

Decrements the reference count on `values` , freeing the structure if the reference count reaches 0.

#### Parameters

values | a GtkTextAttributes |

### gtk_text_attributes_ref ()

    GtkTextAttributes *
    gtk_text_attributes_ref (GtkTextAttributes *values);

Increments the reference count on `values` .

#### Parameters

values | a GtkTextAttributes |

#### Returns

the GtkTextAttributes that were passed in

## Types and Values

### struct GtkTextTag

    struct GtkTextTag;

### struct GtkTextAttributes

    struct GtkTextAttributes {
      GtkTextAppearance appearance;

      GtkJustification justification;
      GtkTextDirection direction;

      PangoFontDescription *font;

      gdouble font_scale;

      gint left_margin;
      gint right_margin;
      gint indent;

      gint pixels_above_lines;
      gint pixels_below_lines;
      gint pixels_inside_wrap;

      PangoTabArray *tabs;

      GtkWrapMode wrap_mode;

      PangoLanguage *language;

      guint invisible : 1;
      guint bg_full_height : 1;
      guint editable : 1;
      guint no_fallback: 1;

      gint letter_spacing;

    #ifdef __GI_SCANNER__
      /* The scanner should only see the transparent union, so that its
       * content does not vary across architectures.
       */
      union {
        gchar *font_features;
    };

Using GtkTextAttributes directly should rarely be necessary. It’s primarily useful with `gtk_text_iter_get_attributes()`. As with most GTK+ structs, the fields in this struct should only be read, never modified directly.
