|
||
* @Title: GtkTextTag
|
||
* @Short_description: A tag that can be applied to text in a GtkTextBuffer
|
||
*
|
||
* You may wish to begin by reading the
|
||
* [text widget conceptual overview][TextWidget]
|
||
* 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.
