|
* The WaylandXdgShellIntegration class is a factory class for xdg-shell clients.
|
||
|
|
*
|
||
|
|
* The xdg-shell protocol defines two surface roles - xdg_toplevel and xdg_popup. On the
|
||
|
|
* compositor side, those roles are represented by XdgToplevelClient and XdgPopupClient,
|
||
|
|
* respectively.
|

|
|
*
|
||
|
|
* WaylandXdgShellIntegration monitors for new xdg_toplevel and xdg_popup objects. If it
|
||
|
|
* detects one, it will create an XdgToplevelClient or XdgPopupClient based on the current
|
||
|
|
* surface role of the underlying xdg_surface object.
