Function grab_input 

pub fn grab_input<F>(with_input: F)
where
    F: FnMut(InputGrabber, Keysym, Modifiers) + Send + 'static,

Grabs keyboard input.

All keyboard input will be redirected to this grabber (assuming another exclusive layer surface doesn’t open). Keybinds will still work.

Don’t forget to add a way to close the grabber, or else input will be grabbed forever!

Examples

input_grab::grab_input(|grabber, key, mods| {
    if key == Keysym::e {
        println!("An `e` was pressed!");
    }

    if key == Keysym::Escape {
        grabber.stop();
    }
});
