Title: wxSmith Hello World code failed
Post by: rts2003 on December 28, 2022, 02:19:53 pm

I followed the Hello World tutorial and ran into a run-time error with the generated code.  I made a StackOverflow post (https://stackoverflow.com/questions/74926012/why-is-wxwidgets-erring-out-when-i-follow-the-instructions) for it.  If someone succeeded in this tutorial, could you please help?

I have followed the Hello World tutorial using:
  - Windows 10
  - Current nightly
  - wxWidgets 3.1.5

and it works as intended, no alert is shown. This is the relevant generated code:

Code

    Create(parent, id, wxEmptyString, wxDefaultPosition, wxDefaultSize, wxDEFAULT_FRAME_STYLE, _T("id"));
    BoxSizer1 = new wxBoxSizer(wxHORIZONTAL);
    Panel1 = new wxPanel(this, ID_PANEL1, wxDefaultPosition, wxDefaultSize, wxTAB_TRAVERSAL, _T("ID_PANEL1"));
    BoxSizer2 = new wxBoxSizer(wxHORIZONTAL);
    StaticText1 = new wxStaticText(Panel1, ID_STATICTEXT1, _("Label"), wxDefaultPosition, wxDefaultSize, 0, _T("ID_STATICTEXT1"));
    BoxSizer2->Add(StaticText1, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    Button1 = new wxButton(Panel1, ID_BUTTON1, _("Label"), wxDefaultPosition, wxDefaultSize, 0, wxDefaultValidator, _T("ID_BUTTON1"));
    BoxSizer2->Add(Button1, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    Panel1->SetSizer(BoxSizer2);
    BoxSizer1->Add(Panel1, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 0);
    SetSizer(BoxSizer1);
    MenuBar1 = new wxMenuBar();
    Menu1 = new wxMenu();
    MenuItem1 = new wxMenuItem(Menu1, idMenuQuit, _("Quit\tAlt-F4"), _("Quit the application"), wxITEM_NORMAL);
    Menu1->Append(MenuItem1);
    MenuBar1->Append(Menu1, _("&File"));
    Menu2 = new wxMenu();
    MenuItem2 = new wxMenuItem(Menu2, idMenuAbout, _("About\tF1"), _("Show info about this application"), wxITEM_NORMAL);
    Menu2->Append(MenuItem2);
    MenuBar1->Append(Menu2, _("Help"));
    SetMenuBar(MenuBar1);
    StatusBar1 = new wxStatusBar(this, ID_STATUSBAR1, 0, _T("ID_STATUSBAR1"));
    int __wxStatusBarWidths_1[1] = { -1 };
    int __wxStatusBarStyles_1[1] = { wxSB_NORMAL };
    StatusBar1->SetFieldsCount(1,__wxStatusBarWidths_1);
    StatusBar1->SetStatusStyles(1,__wxStatusBarStyles_1);
    SetStatusBar(StatusBar1);
    BoxSizer1->SetSizeHints(this);

Many thanks, Miguel.  I figured out where the error came from.  The details are in that StackOverflow post.  By the way, do you know the reason why not using wxDefaultSize causes it to fail?
