hm... not happened (core dumped when put empty)

Just like the message says: you forgot to define the constructor for
class MyTreeCtrl. There's a declaration in the class, but no
definition (no function body).

Of course. You need to do something in that constructor. Minimally,
you have to construct the base classes (wxTreeCtrl in this case).

Outside the class declaration...

Maybe you need a C++ textbook. I've fount "C++ in a nutshell" (from
O'Reilly publications) to be very good.

What is wrong?

[Lukasz Michalski]

How do you know that it is not run?

yes, but Message not activate. Never activate. I ask why?

[Lukasz Michalski]

Thats why I asked how do you know that it is run or not. The printf function

does nothing under MS Windows GUI application.

Try wxMessgageBox.

Change it to this:

MyTreeCtrl::MyTreeCtrl(wxWindow *parent, const wxWindowID id, const wxPoint& pos, const wxSize& size, long style) :

wxTreeCtrl(parent, id, pos, size, style)
{
    //any other initialisation code here
};


This way, as Paul was saying, you are initialising the base class.
