Title: Events and threads
Post by: Nitroreg on February 07, 2012, 06:27:18 pm

I'm trying to handle events in a thread.
That seems not to work, "PollEvent" never returns true and "WaitEvent" never returns at all.

Is sf::Window thread-safe?
Can I call "Display" in the main thread and "PollEvent / WaitEvent" in a different thread?

Thanks

Thanks, events work in the main thread but graphics don't work if there are not in the main thread. When Display is called this error is printed on the output.
"Failed to activate the window's context"
The OpenGL context's version is 3.1

No, they work in the thread where the window is created.

Graphics work anywhere, as long as the window has first been deactivate in the thread where it was active.
