Cannot create window of class wxWindowNR

Question

I want to create a second independent window using C++/wxWidgets and I get an error "cannot create window of class wxWindowNR" at runtime and the second window doesn't show up. No compiler/linker errors.

The offending code is:

void test_gui(){ ActorDetails *ac = new ActorDetails(wxGetApp().GetTopWindow(),wxID_ANY,wxDefaultPosition,wxDefaultSize); //ActorDetails inherits wxFrame wxPanel *Panel1 = new wxPanel(ac, wxNewId(), wxPoint(256,224), wxDefaultSize, wxTAB_TRAVERSAL, _T("ID_PANEL1")); ac->Show(true); }

Any idea what's going on/going wrong?

There is nothing wrong in the code you show, so there must be something wrong in the code you do not show, namely ActorDetails ctor. — VZ.

I'd the same error message today. Most probably you forgot to call the wxFrame constructor from your ActorDetails constructor.

replacing

ActorDetails *ac = new ActorDetails(wxGetApp().GetTopWindow(),wxID_ANY,wxDefaultPosition,wxDefaultSize);

with

ActorDetails *ac = new ActorDetails(); ac->Create(wxGetApp().GetTopWindow(), wxNewId(), _("Existenz Console"), wxDefaultPosition, wxDefaultSize, wxDEFAULT_FRAME_STYLE, _T("id"));

now produces a window as expected. Unfortunately I do not know what the difference is, but the second variant of code successfully instantiates and shows the second wxFrame.

This of course required the addition of a new empty constructor no parameter constructor to the class ActorDetails (not shown here).
