[−][src]Trait wayland_protocols::unstable::xdg_shell::v6::client::zxdg_shell_v6::EventHandler
An interface for handling events.
Provided methods
fn ping(&mut self, object: ZxdgShellV6, serial: u32)
check if the client is alive
The ping event asks the client if it's still alive. Pass the serial specified in the event back to the compositor by sending a "pong" request back with the specified serial. See xdg_shell.ping.
Compositors can use this to determine if the client is still alive. It's unspecified what will happen if the client doesn't respond to the ping request, or in what timeframe. Clients should try to respond in a reasonable amount of time.
A compositor is free to ping in any way it wants, but a client must always respond to any xdg_shell object it created.
