Hi, when I try to open a wxsmith file in my built C::B against wx 3.3.1, I see a crash, here is the crash call stack:

Any ideas?

Thanks.

Re: crash when I try to open a wxsmith file under C::B against wx 3.3.1

It crashed in the return statement:

Code
#if WXWIN_COMPATIBILITY_3_2
    mutable bool m_oldGetValueAsString = false;
    wxString GetValueAsStringWithCheck(wxPGPropValFormatFlags flags = wxPGPropValFormatFlags::Null) const;
    wxDEPRECATED_BUT_USED_INTERNALLY_MSG("use GetValueAsString with 'flags' argument as wxPGPropValFormatFlags")
    virtual wxString GetValueAsString(int flags) const
    {
        m_oldGetValueAsString = true;
        return GetValueAsString(static_cast<wxPGPropValFormatFlags>(flags));
    }

In the F:\code\wxWidgets-3.3.1\include\wx\propgrid\property.h file.

I try to use an old C::B which is built against wx 3.2.x, and I don't see the crash.

It is not a crash, but an assertion.

This looks to me like a wxWidgets issue. At first glance, this line
Code
       return GetValueAsString(static_cast<wxPGPropValFormatFlags>(flags));
should be
Code
       return GetValueAsStringWithCheck(static_cast<wxPGPropValFormatFlags>(flags));

So, this should be handled inside the wxWidgets' code? Not in our C::B's code base?

In wxSmith there is only one call to wxPGProperty::GetValueAsString(), and it has no parameters. Also, wxSmith does not appear in the stack trace, the relation with wxSmith may be that it is the only one that uses wxPropertyGrid at all.

Looks like the call is made from wxPGDefaultRenderer::Render() inside wxPropertyGrid::OnPaint() event handler.
