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().

gtk_text_tag_get_priority ()

gint
gtk_text_tag_get_priority (GtkTextTag *tag);

Get the tag priority.

gtk_text_tag_set_priority ()

void
gtk_text_tag_set_priority (GtkTextTag *tag,
                           gint priority);

Sets the priority of a GtkTextTag. Valid priorities are 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.

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.

gtk_text_attributes_new ()

GtkTextAttributes *
gtk_text_attributes_new (void);

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

gtk_text_attributes_copy ()

GtkTextAttributes *
gtk_text_attributes_copy (GtkTextAttributes *src);

Copies src and returns a new GtkTextAttributes.

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 .

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.

gtk_text_attributes_ref ()

GtkTextAttributes *
gtk_text_attributes_ref (GtkTextAttributes *values);

Increments the reference count on values .
