Interface WlShellSurfaceEvents

public interface WlShellSurfaceEvents

desktop-style metadata interface

An interface that may be implemented by a wl_surface, for implementations that provide a desktop-style user interface.

It provides requests to treat surfaces like toplevel, fullscreen or popup windows, move, resize or maximize them, associate metadata like title and class, etc.

On the server side the object is automatically destroyed when the related wl_surface is destroyed. On the client side, wl_shell_surface_destroy() must be called before destroying the wl_surface object.

Method Details

ping

void ping(WlShellSurfaceProxy emitter,
 int serial)

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.

Parameters:

emitter - The protocol object that emitted the event.

serial - serial number of the ping

configure

void configure(WlShellSurfaceProxy emitter,
 int edges,
 int width,
 int height)

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.

Parameters:

emitter - The protocol object that emitted the event.

edges - how the surface was resized

width - new width of the surface

height - new height of the surface

popupDone

void popupDone(WlShellSurfaceProxy emitter)

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.

Parameters:

emitter - The protocol object that emitted the event.
