Getting Started

Git submodule setup

https://docs.wxwidgets.org/trunk/overview_cmake.html#cmake_subdir

  • Clone wxwidgets to the `extern` folder
  • Add the following to your cmakelists:
add_subdirectory(extern/wxWidgets EXCLUDE_FROM_ALL)
#...
target_link_libraries(my_app wx::net wx::core wx::base)

SDL2 Integration

You can make an SDL window out of a wxPanel in a wxFrame:

SDL_CreateWindowFrom((void*)panel->GetHandle())

Make sure you delete the window in the onClose method of your frame.
You may also want to create a render loop

Initializing SDL

Define your own main function:

wxIMPLEMENT_APP_NO_MAIN(MyApp);

bool MyApp::OnInit() {
  frame = new MyFrame();
  frame->Show();
  return true;
}

#ifdef _WIN32
int wmain(int argc, char* argv[]) {
  std::ignore = _putenv("SDL_AUDIODRIVER=directsound");
#else
int main(int argc, char* argv[]) {
#endif
  if (SDL_Init(SDL_INIT_EVERYTHING) < 0) {
    std::cerr << "Could not initialize SDL.\n";
    return 1;
  }
  int rv = wxEntry(argc, argv);
  SDL_Quit();
  return rv;
}
