### Virtual Method

# Gtk TextBufferbegin_user_action

#### Declaration [src]

    void
    begin_user_action (
      GtkTextBuffer* buffer
    )

#### Description [src]

Called to indicate that the buffer operations between here and a call to `gtk_text_buffer_end_user_action()` are part of a single user-visible operation.

The operations between `gtk_text_buffer_begin_user_action()` and `gtk_text_buffer_end_user_action()` can then be grouped when creating an undo stack. `GtkTextBuffer` maintains a count of calls to `gtk_text_buffer_begin_user_action()` that have not been closed with a call to gtk_text_buffer_end_user_action(), and emits the “begin-user-action” and “end-user-action” signals only for the outermost pair of calls. This allows you to build user actions from other user actions.

The “interactive” buffer mutation functions, such as `gtk_text_buffer_insert_interactive()`, automatically call begin/end user action around the buffer operations they perform, so there’s no need to add extra calls if you user action consists solely of a single call to one of those functions.
