Feature requests / Re: Add additional events polling

Ok, I figured out that I could just create new window, hide it and use only for WM_COPYDATA event handling.
It's not as convinient as just adding event handler, but works.
Nevertheless I think you should consider adding ability to handle additional events

Feature requests / Add additional events polling

« on: March 10, 2020, 04:21:01 pm »

I'm writing an application to debug another process, so I want to send debug data to draw from that process to sfml renderer. As both applications are windows only, I wanted to use WM_COPYDATA events to send data.
But I can't just add such event handler: the only way, that I see to do such thing is to create OS Window by myself, writing event handler for myself including all the events sfml can handle, and then pass a window to a sf::Window.
IMO this is very unconvinient, so I ask to do a way, that I could (may be os specific) add additional events polling.

I see 2 ways of doing that:
1) (probably preferred) add some os-specific handler in sf::Window and call it whenever your inner event handler works
Like:

LRESULT sf::WindowImpl32::pollEvent(UINT msg, WPARAM wParam, LPARAM lParam) {
  if (customHandler)
    customHandler(msg, wParam, lParam);
  // do usual stuff
}

2) Add ability to call your event handler from the outside, so even if I'm creating OS Window by myself, I could write something like

LRESULT CALLBACK HandleWindowEvents(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
  // do my stuff
  sf::Window::DefaultHandler(hwnd, msg, wParam, lParam);
}

May be there is another good way

Thanks
