# Method GTK2.TextBuffer()->begin_user_action()

Method begin_user_action

  `GTK2.TextBuffer begin_user_action()`

Description

  Called to indicate that the buffer operations between here and call end_user_action() are part of a single user-visible operation. The operations between begin_user_action() and end_user_action() can then be grouped when creating an undo stack. W(TextBuffer) maintains a count of calls to begin_user_action() that have not been closed with a call to 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 insert_interactive(), automatically call begin/end user action around the buffer operations they perform, so there's no need to add extra calls if your user action consists solely of a single call to one of those functions.
