In C++20, there will be emit() class member, which can conflict with the emit keyword. Given that, there are plans to enable QT_NO_KEYWORDS by default in the future. See also https://lists.qt-project.org/pipermail/development/2020-February/038812.html

|
|
* 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.
