Threading for WebSocket

[xarthurx]

I've read multiple issues relating to threading for non-OpenGL process but am still not very clear if imgui can do this or not.
So sorry for the spam here.

Need:
In my UI, I have two buttons: startServer and stopServer, which will start/stop a WebSocket Server.
The Server will receive data from time to time and send things back after processing the data.

The main UI can be blocked or not blocked after starting the Server, but I would like to have the functionality to press stopServer.
Meanwhile, after I press the startServer, the main UI is frozen after the WebSockets started.

From what I understand, I need to put it in another thread.
But does imgui allows this? I'm not vary familiar with GUI and would like to know if the instant gui (imgui) can do this.

Here, imgui wouldn't really have any sort of interaction with your threaded code. Your C/C++ code is responsible for being the threadsafe one.

Something like this:

if (ImGui::Button("Start Server")) {
    threadSafeEventStartServer();
}

ImGui::SameLine();

if (ImGui::Button("Stop Server")) {
    threadSafeEventStopServer();
}

You are responsible for writing theradSafeEventStartServer() and threadSafeEventStopServer() in a thread safe manner that is.

Thank you!

I'm just confused if ImGui can do this or not after reading some of the issues.
Since it can, I'll handle the rest part.
