   \internal If the Fl_Group widget contains the Fl::focus() or the
   Fl::pushed() widget these are set to sensible values (other widgets
   or the Fl_Group widget itself).
+
+  \note FLTK's auto-delete feature efficiently manages widget hierarchies in
+  C++ applications by automatically cleaning up. However, this feature can
+  cause issues when FLTK is used with reference-counting languages like Python,
+  where automatic deletion might interfere with reference counting. To address
+  this, auto-delete can be disabled for individual widgets. When
+  \ref Fl_Group::clear() is called, it sends an \ref FL_AUTO_DELETE event to
+  each widget. If a widget returns 1 in response to this event, it will not
+  be deleted. In a Python wrapper, this behavior would typically involve
+  decrementing the widget's reference count instead of deleting it.
