Hi,
I'm experiencing some strange behaviour when trying to print class names of
wxWindow objects from the wxLuaWinDestroyCallback constructor and destructors.
I think this has to do with my lack of knowledge about C++ so I'd be glad if
someone could explain to me why this happens.
I added the following three printf()'s to wxlcallb.cpp:
1) In wxLuaWinDestroyCallback::wxLuaWinDestroyCallback:
printf("*** CONSTRUCTOR: %p NAME: %s\n", m_window,
m_window->GetClassInfo()->GetClassName());
2) In wxLuaWinDestroyCallback::~wxLuaWinDestroyCallback():
printf("*** DESTRUCTOR: %p NAME: %s\n", m_window,
m_window->GetClassInfo()->GetClassName());
3) In void wxLuaWinDestroyCallback::OnAllDestroyEvents(wxWindowDestroyEvent&
event):
printf("*** ONALLDESTROY: %p NAME: %s\n", theCallback->m_window,
theCallback->m_window->GetClassInfo()->GetClassName());
For wxWindow of type wxFrame I get the following output:
*** CONSTRUCTOR: 03C7EE18 NAME: wxFrame
*** ONALLDESTROY: 03C7EE18 NAME: wxWindow
*** DESTRUCTOR: 03C7EE18 NAME: wxEvtHandler
What is confusing me here is this: The m_window pointer is always the same but
in each
callback I get a different class name. How can this be? I'd expect to get
"wxFrame"
in each callback but instead I get "wxFrame" only in the constructor. In the
other
two callbacks it is "wxWindow" and then even "wxEvtHandler".... I don't
understand
this. What is going on there?
Thanks!
