Re: Which dialog classes can function without a top-level frame?

Thank you for your answer.

I looked what you said (
https://docs.wxwidgets.org/3.2/group__group__funcmacro__appinitterm.html)
and tried different things. However, the program continues to give
segmentation faults.

Here is the new version of the code:
```c++
#define BIGA_EXPORTS

#include "biga/ui/native/message_box.hpp"

#ifndef WX_PRECOMP
#include "wx/wx.h"
#endif

#include "wx/aboutdlg.h"
#include "wx/app.h"

#include "biga/internal/log.hpp"
#include "wx/button.h"
#include "wx/msgdlg.h"

namespace biga::ui::native
{


BIGA_EXPORT
bool Initialize(int argCount, const char *argList[]) noexcept
{
SPDLOG_DEBUG("called");
return wxInitialize(argCount, const_cast<char **>(argList));
// i am tried thats but doesn't work:
// return wxEntryStart(argCount, const_cast<char **>(argList));
// wxInitialize(argCount,
// const_cast<char **>(argList));
}

BIGA_EXPORT
void NativeAboutBox(const std::string programName,
          const std::string &proVversion,
          const std::string &progDescription,
          const std::string &copyright,
          const std::string &licence, const std::string &webSite)
{
 SPDLOG_DEBUG("called");
 wxAboutDialogInfo info;
 info.SetName(programName);
 info.SetVersion(proVversion);
 info.SetDescription(progDescription);
 info.SetCopyright(copyright);
 info.SetWebSite(webSite);
 info.SetLicence(licence);

 wxAboutBox(info, nullptr);
 SPDLOG_DEBUG("end");
}
}  // namespace biga::ui::native
```

usage code (main.cpp):
```c++
#include <iostream>

#include "biga/ui/native/about_box.hpp"
#include "biga/ui/native/native.hpp"

int main(int argCount, const char* argList[])
{
if (! biga::ui::native::Initialize(argCount, argList))
{
std::cerr << "Failed to initialize native UI" << std::endl;
return 1;
}
std::cout << "wxwidgets initialized\n";
// initialize is successful, not problem.
biga::ui::native::NativeAboutBox(
"Biga", "v b1.4", "this is a description",
"copyright seantolstoyevski and all contrubitors.", "",
"https://github.com/seantolstoyevski/biga");
return 0;
}
```
