/** |
|
* The WaylandXdgShellIntegration class is a factory class for xdg-shell windows. |
|
* |
|
* The xdg-shell protocol defines two surface roles - xdg_toplevel and xdg_popup. On the |
|
* compositor side, those roles are represented by XdgToplevelWindow and XdgPopupWindow, |
|
* respectively. |
|
* |
|
* WaylandXdgShellIntegration monitors for new xdg_toplevel and xdg_popup objects. If it |
|
* detects one, it will create an XdgToplevelWindow or XdgPopupWindow based on the current |
|
* surface role of the underlying xdg_surface object. |
