Variants

Ping

ping client

Ping a client to check if it is receiving events and sending requests. A client is expected to reply with a pong request.

Fields of Ping

serial: u32

Configure

suggest resize

The configure event asks the client to resize its surface.

The size is a hint, in the sense that the client is free to ignore it if it doesn't resize, pick a smaller size (to satisfy aspect ratio or resize in steps of NxM pixels).

The edges parameter provides a hint about how the surface was resized. The client may use this information to decide how to adjust its content to the new size (e.g. a scrolling area might adjust its content position to leave the viewable content unmoved).

The client is free to dismiss all but the last configure event it received.

The width and height arguments specify the size of the window in surface-local coordinates.

Fields of Configure

edges: Resize
width: i32
height: i32

PopupDone

popup interaction is done

The popup_done event is sent out when a popup grab is broken, that is, when the user clicks a surface that doesn't belong to the client owning the popup surface.
