Constructor & Destructor Documentation

◆ MythPainter()

MythPainter::MythPainter ( )

Definition at line 22 of file mythpainter.cpp.

◆ ~MythPainter()

virtual MythPainter::~MythPainter ( )

virtualdefault

MythPainter destructor.

The MythPainter destructor does not cleanup, it is unsafe to do cleanup in the MythPainter destructor because DeleteImagePriv() is a pure virtual in this class. Instead children should call MythPainter::Teardown() for cleanup.
