Ancestors

Constructors

talkatu_buffer_new

This is a simple GtkTextBuffer subclass that contains the shared behavior for the other Talkatu text buffers.

Instance methods

talkatu_buffer_get_action_group

A TalkatuBuffer can support multiple actions, whether it’s formatting of text, or being able to insert images, code, etc. This function is called by TalkatuView to map them to keybindings as well as the format toolbar.

talkatu_buffer_get_is_empty

Returns whether or not buffer has any text in it.

talkatu_buffer_get_plain_text

Returns the text from the buffer without markup.

talkatu_buffer_get_style

Gets format style of buffer.

talkatu_buffer_insert_link

Inserts a link into buffer with the given url and display_text. If display_text is not given, url will be used.

talkatu_buffer_insert_markup

Inserts text that will be or already is marked up. Calling this tells buffer to not apply the currently selected format to the newly inserted text, which is what it does when text is normally inserted.

talkatu_buffer_insert_markup_with_tags_by_name

Similar to #talkatu_buffer_insert_markup but allows you to specify tags to apply to the newly inserted text.

talkatu_buffer_set_action_group

Sets the GSimpleActionGroup of buffer to action_group. action_group is used to determine what formatting tags are currently enabled among other things.
