Match on events & XSelectInput mask

[Peekmo]

Hello !

First of all, thank you for those bindings, great work !
This is more some questions than issues :

• How do you check for the received event with that lib ??

I tried this :

loop {
         let ev: *mut xlib::XEvent;
         unsafe {
             xlib::XNextEvent(dpy, ev);
         }

         match ev {
             xlib::XExposeEvent => println!("Ok"),
             _ => println!("Nothing"),
         }
     };

But it does not compile ( unresolved enum variant, struct or const XExposeEvent ) I'm new to rust, and I'm doing this little project with xlib & rust to learn both ^^ So my question should be stupid...

• Secondly, is there anything to applying masks (like ExposeMask) to XSelectInput ? Or not for the moment ?

Thank you
Regards,

I don't know if anybody has written Rust code to process events using rust-xlib yet. It certainly doesn't look like it will work well right now, since XEvent isn't actually defined to take up any space. If you look at what the glutin library does, you can get a better sense of how this should be used - https://github.com/tomaka/glutin/blob/master/src/x11/ffi.rs#L1241

Similarly, https://github.com/tomaka/glutin/blob/master/src/x11/window/mod.rs#L455 should what your code should end up looking like.

In fact, it's more like the C code.

Thank you for your answer and for the link to Glutin 👍

Is this not a valid bug in this xlib library though? Shouldn't this issue be kept open until actually resolved?
