set-cursor

Sets a custom cursor for the editor. If the custom cursor is #f, the current cursor is removed, and a cursor is selected automatically by the editor (depending on whether the cursor is pointing at a clickback). See adjust-cursor for more information about the default selection.

An embedding editor's custom cursor can override the cursor of an embedded editor -- even if the embedded editor has the caret -- if the cursor is specified as an overriding cursor.

• (send an-editor set-cursor cursor override?) -> void
      cursor : cursor% object or #f
      override? = #t : boolean

  Sets the custom cursor for the editor to cursor. If override? is a true value and cursor is not #f, then this cursor overrides cursor settings in embedded editors.
