I want to use HDC m_hdc=GetDC() and paint myself. I've found RemoveFullRefresh() method but I've got an error:
Ctrl::RemoveFullRefresh' : cannot access private member declared in class 'Ctrl'. How could I use it or what are the alternatives?

What do you expect from RemoveFullRefresh?

"HDC" painting should go like this:

void MyCtrl::Paint(Draw& w)
{
   HDC hdc = w.BeginGdi();
// now use hdc
   w.EndGdi();   
}

Of course, this is Win32 platform specific...

In X11, equivalent methods are:

XftDraw *GetXftDraw() const;
GetDrawable() const;
GC GetGC() const;

Yes, thank you, this works. But I wanted to disable U++ Paint-Draw system Smile

Even that is possible. Depends on what level you want to do that. Relatively safe option is to use DHCtrl, which is special Ctrl that has HWND (normal Ctrls do not). Then override WindowProc and handle WM_PAINT messages.
