2008-Apr-22 UPDATE Dick Hollenbeck <dick@softplc.com>
================================================================================
+eeschema
* Spent a 1/2 day tracking down two linked list bugs in deleting a
DRAW_HIERARCHICAL_PIN_SHEET_STRUCT_TYPE. I cannot believe in the year
2008 we should have to debug a linked list function. This is stuff I expected
to do 20 years ago, not today. The function
void WinEDA_SchematicFrame::DeleteSheetLabel( wxDC* DC,
Hierarchical_PIN_Sheet_Struct* SheetLabelToDel ) never worked as
far as I can tell.
Should switch to boost::ptr_vector ASAP everywhere, and leave linked lists in the 1980's.
* Hierarchical_PIN_Sheet_Struct::Hierarchical_PIN_Sheet_Struct() was not
setting the m_Parent.
