The documentation (https://docs.wxwidgets.org/3.2/classwx_static_box_sizer.html) say that the child of a wxStaticBoxSizer should be the wxBoxSizer and not the owner of the wxStaticBoxSizer.
On Linux, for example, I can see the following warning on the console:
Element wxStaticText of wxStaticBoxSizer should be created as child of its wxStaticBox and not of wxDialog.
I test several builder on a very simple case: a dialog window with a wxStaticBoxSizer that contain a wxStaticText and a wxTextCtrl.
With wxSmith:
DialogFormSmith::DialogFormSmith(wxWindow* parent,wxWindowID id)
{
//(*Initialize(DialogFormSmith)
wxStaticBoxSizer* StaticBoxSizer1;
Create(parent, id, _("Test with wxSmith"), wxDefaultPosition, wxDefaultSize, wxDEFAULT_DIALOG_STYLE, _T("id"));
StaticBoxSizer1 = new wxStaticBoxSizer(wxHORIZONTAL, this, _("StaticBoxSizer"));
StaticText1 = new wxStaticText(this, wxID_ANY, _("Label"), wxDefaultPosition, wxDefaultSize, 0);
StaticBoxSizer1->Add(StaticText1, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
TextCtrl1 = new wxTextCtrl(this, wxID_ANY, _("Text"), wxDefaultPosition, wxDefaultSize, 0, wxDefaultValidator);
StaticBoxSizer1->Add(TextCtrl1, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
SetSizer(StaticBoxSizer1);
StaticBoxSizer1->SetSizeHints(this);
//*)
}
with wxFormBuilder:
DialogFormBuilder::DialogFormBuilder( wxWindow* parent, wxWindowID id, const wxString& title, const wxPoint& pos, const wxSize& size, long style ) : wxDialog( parent, id, title, pos, size, style )
{
this->SetSizeHints( wxDefaultSize, wxDefaultSize );
wxStaticBoxSizer* sbSizer1;
sbSizer1 = new wxStaticBoxSizer( new wxStaticBox( this, wxID_ANY, _("StaticBoxSizer") ), wxHORIZONTAL );
m_staticText1 = new wxStaticText( sbSizer1->GetStaticBox(), wxID_ANY, _("MyLabel"), wxDefaultPosition, wxDefaultSize, 0 );
m_staticText1->Wrap( -1 );
sbSizer1->Add( m_staticText1, 0, wxALL, 5 );
m_textCtrl1 = new wxTextCtrl( sbSizer1->GetStaticBox(), wxID_ANY, wxEmptyString, wxDefaultPosition, wxDefaultSize, 0 );
sbSizer1->Add( m_textCtrl1, 0, wxALL, 5 );
this->SetSizer( sbSizer1 );
this->Layout();
sbSizer1->Fit( this );
this->Centre( wxBOTH );
}
With wxGlade:
DialogFormGlade::DialogFormGlade(wxWindow* parent, wxWindowID id, const wxString& title, const wxPoint& pos, const wxSize& size, long style):
wxDialog(parent, id, title, pos, size, wxDEFAULT_DIALOG_STYLE)
{
// begin wxGlade: DialogFormGlade::DialogFormGlade
SetTitle(wxT("Test with wxGlade"));
wxStaticBoxSizer* sizer_1 = new wxStaticBoxSizer(new wxStaticBox(this, wxID_ANY, wxT("StaticBoxSizer")), wxHORIZONTAL);
wxStaticText* label_1 = new wxStaticText(sizer_1->GetStaticBox(), wxID_ANY, wxT("Label"));
sizer_1->Add(label_1, 0, 0, 0);
text_ctrl_1 = new wxTextCtrl(sizer_1->GetStaticBox(), wxID_ANY, wxEmptyString);
sizer_1->Add(text_ctrl_1, 0, 0, 0);
SetSizer(sizer_1);
sizer_1->Fit(this);
Layout();
// end wxGlade
}
The codes generated by wxFormBuilder and wxGlade are good: no warning.
I join a complete project for testing

We can correct the code simply by:
- replace this by StaticBoxSizer1->GetStaticBox() in the wxStaticText and wxTextCtrl constructor
- add the include <wx/statbox.h>
-
I try to find a patch to correct this.
First, we can add a temporary wxStaticBox when we add the wxStaticBoxSizer.
In the file wxsstaticboxsizer.cpp we replace in OnBuildSizerCreatingCode() function this code:
case wxsCPP:
{
AddHeader(_T("<wx/sizer.h>"),GetInfo().ClassName,hfInPCH);
AddHeader(_T("<wx/statbox.h>"),GetInfo().ClassName,hfInPCH);
Codef(_T("%C(%s, %W, %t);\n"),
(Orient!=wxHORIZONTAL)?_T("wxVERTICAL"):_T("wxHORIZONTAL"),
Label.wx_str());
Codef(_T("wxStaticBox *SB_%s = %s->GetStaticBox();\n"),GetVarName().wx_str(),GetVarName().wx_str());
return;
}
The problem now is to replace, in all constructors of the children of wxStaticBoxSizer, the parent with this temporary wxStaticBox.
I don't know how to do it right now.

wxSmith is complex and the original developer is no longer around. I plan to fix this, but I currently have no free time.

The main difficulty lies in the fact that wxStaticBoxSizer is both a sizer and a container. In the current code, wxStaticBoxSizer is classified as a sizer, and there is no category for an object that is both a sizer and a container.
The difficulty lies in finding the owner of the child elements of wxStaticBoxSizer. Currently, it is the parent of the wxStaticBoxSizer that is found, and that is the problem.
The problem is clear, the solution less so!
We will probably need to create a new category and the wxsStaticBoxSizer class will need to inherit from wxsSizer and wxsContainer :P
