after-insert

Called after items are inserted into the editor (and after the display is refreshed; use on-insert and begin-edit-sequence to avoid extra refreshes when after-insert modifies the editor).

See also can-insert? and on-edit-sequence.

No internals locks are set when this method is called.

• (send a-text:info-mixin after-insert start len) -> void
      start : exact non-negative integer
      len : exact non-negative integer

  The start argument specifies the position of the insert. The len argument specifies the total length (in positions) of the inserted items.

  Calls the editor-position-changed method of the frame that is viewing this object. It uses get-canvas to get the canvas for this frame, and uses that canvas's top-level-window<%> as the frame.
