ziacko / tinywindow Goto Github PK

SFML has virtually no support for multiple monitors or monitor detection. I was just wondering, would it be possible to add something like this to TinyWindow? Some sort of API to determine which monitor a window geta drawn onto?

use RandR if necessary

I am using Arch linux and i tried building the example project. I get the following errors from TinyWindow.h
errors.txt
I get the same errors in any project where I use TinyWindow.

Thanks for the help!

Git is not designed to handle zip files, this is a very bad idea. Just put the docs in their own directory and commit them normally like any other code.

need to implement event handling for windows that would allow windows to receive events without the use of the window manager

I've had TinyWindow working with a previous version and msvc 2013. With the latest version combined with msvc 2017, it crashes on the following line:

glRenderingContextHandle = wglCreateContextAttribsARB(window->deviceContextHandle, NULL, attribs);

I've traced it back to where I think the problem starts - this line:

wglMakeCurrent(dummyDeviceContextHandle, glDummyContextHandle);

This returns 0, but does not set a windows error. The extension function addresses end up NULL and eventually it crashes on wglCreateContextAttribsARB(...) because the function address is NULL.

I've also noticed that there is minimal error handling. I used the following function that I found elsewhere to help debug this issue. It seems that there are dozens of windows functions that are not error checked, which I can understand for a prototype, but for the library to mature I think it will be very helpful.

auto GetLastErrorStdStr() -> std::string
{
DWORD error = GetLastError();
if (error)
{
LPVOID lpMsgBuf;
DWORD bufLen = FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
error,
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf,
0, NULL );
if (bufLen)
{
LPCSTR lpMsgStr = (LPCSTR)lpMsgBuf;
std::string result(lpMsgStr, lpMsgStr+bufLen);

  LocalFree(lpMsgBuf);

  return result;
}

}
return std::string();
}
#include
#define printWinError std::cout << "\n" << LINE << " windows error " << GetLastErrorStdStr() << std::endl;

Let me know if I can do anything else to help!

At line 1286 it looks like the resolution parameter of the AddWindow function doesn't use the resolution parameter. Should this be changed to call SetResolution?

You have error, else is without if , if we are on linux platform
I changed that and put else in the #ifdef windows.
But when i run the Example.cpp, when i press space it gets segmentation fault
