Variants

Configure

suggest a surface change

The configure event asks the client to resize its surface or to change its state.

The width and height arguments specify a hint to the window about how its surface should be resized in window geometry coordinates. See set_window_geometry.

If the width or height arguments are zero, it means the client should decide its own window dimension. This may happen when the compositor need to configure the state of the surface but doesn't have any information about any previous or expected dimension.

The states listed in the event specify how the width/height arguments should be interpreted, and possibly how it should be drawn.

Clients should arrange their surface for the new size and states, and then send a ack_configure request with the serial sent in this configure event at some point before committing the new surface.

If the client receives multiple configure events before it can respond to one, it is free to discard all but the last event it received.

Close

surface wants to be closed

The close event is sent by the compositor when the user wants the surface to be closed. This should be equivalent to the user clicking the close button in client-side decorations, if your application has any...

This is only a request that the user intends to close your window. The client may choose to ignore this request, or show a dialog to ask the user to save their data...
