void set_priority(int priority
Sets the priority of the tag to priority. Valid
priority values are 0 through
one less than the number of tags in the
Priorities are used to resolve conflicts when two tags attempt to set the
same attribute across the same range of text. The values of the tag with
the higher priority will take precedence over the values of the tag with
the lower priority.
Priorities are unique for all tags in a given
GtkTextTagTable. By default, priorties are
assigned in the order the tags are added to the table. If the priority of
a tag is changed, all other tags' priorities are adjusted.
