Constructor & Destructor Documentation

MythPainter()

MythPainter::MythPainter

(

)

Definition at line 23 of file mythpainter.cpp.

~MythPainter()

MythPainter::~MythPainter ( )

overridedefault

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.
