MozContainer.cpp MOZ_LOGGING 12713
MozContainer.h MozContainer This class serves three purposes in the nsIWidget implementation. - It provides objects to receive signals from GTK for events on native windows. - It provides GdkWindow to draw content on Wayland or when Gtk+ renders client side decorations to mShell. - It provides a container parent for GtkWidgets. The only GtkWidgets that need this in Mozilla are the GtkSockets for windowed plugins (Xt and XEmbed). Note that the window hierarchy in Mozilla differs from conventional GtkWidget hierarchies. Mozilla's hierarchy exists through the GdkWindow hierarchy, and all child GdkWindows (within a child nsIWidget hierarchy) belong to one MozContainer GtkWidget. If the MozContainer is unrealized or its GdkWindows are destroyed for some other reason, then the hierarchy no longer exists. (In conventional GTK clients, the hierarchy is recorded by the GtkWidgets, and so can be re-established after destruction of the GdkWindows.) One consequence of this is that the MozContainer does not know which of its GdkWindows should parent child GtkWidgets. (Conventional GtkContainers determine which GdkWindow to assign child GtkWidgets.) Therefore, when adding a child GtkWidget to a MozContainer, gtk_widget_set_parent_window should be called on the child GtkWidget before it is realized. 3176
MozContainerWayland.cpp MozContainerWayland is a wrapper over MozContainer which provides wl_surface for MozContainer widget. The widget scheme looks like: --------------------------------------------------------- | mShell Gtk widget (contains wl_surface owned by Gtk+) | | | | --------------------------------------------------- | | | mContainer (contains wl_surface owned by Gtk+) | | | | | | | | --------------------------------------------- | | | | | wl_subsurface (attached to wl_surface | | | | | | of mContainer) | | | | | | | | | | | | | | | | | --------------------------------------------- | | | --------------------------------------------------- | --------------------------------------------------------- We draw to wl_subsurface owned by MozContainerWayland. We need to wait until wl_surface of mContainer is created and then we create and attach our wl_subsurface to it. First wl_subsurface creation has these steps: 1) moz_container_wayland_size_allocate() handler is called when mContainer size/position is known. It calls moz_container_wayland_surface_create_locked(), registers a frame callback handler moz_container_wayland_frame_callback_handler(). 2) moz_container_wayland_frame_callback_handler() is called when wl_surface owned by mozContainer is ready. We call initial_draw_cbs() handler and we can create our wl_subsurface on top of wl_surface owned by mozContainer. When MozContainer hides/show again, moz_container_wayland_size_allocate() handler may not be called as MozContainer size is set. So after first show/hide sequence use moz_container_wayland_map_event() to create wl_subsurface of MozContainer. 25576

MPRISInterfaceDescription.h 5176
MPRISServiceHandler.cpp 29078
MPRISServiceHandler.h This class implements the "MPRIS" D-Bus Service (, which is used to communicate with the Desktop Environment about the Multimedia playing in Gecko. Note that this interface requires many methods which may not be supported by Gecko, the interface however provides CanXYZ properties for these methods, so the method is defined but won't be executed. Also note that the following defines are for parts that the MPRIS Spec defines optional. The code won't compile with any of the defines set, yet, as those aren't implemented yet and probably never will be of use for gecko. For sake of completeness, they have been added until the decision about their implementation is finally made. The constexpr'ed methods are capabilities of the user agent known at compile time, e.g. we decided at compile time whether we ever want to support closing the user agent via MPRIS (Quit() and CanQuit()). Other properties like CanPlay() might depend on the runtime state (is there media available for playback?) and thus aren't a constexpr but merely a const method. 6830

nsGtkKeyUtils.cpp 86395
nsGtkKeyUtils.h KeymapWrapper is a wrapper class of GdkKeymap. GdkKeymap doesn't support all our needs, therefore, we need to access lower level APIs. But such code is usually complex and might be slow. Against such issues, we should cache some information. This class provides only static methods. The methods is using internal singleton instance which is initialized by default GdkKeymap. When the GdkKeymap is destroyed, the singleton instance will be destroyed. 15848

WaylandVsyncSource.cpp 7514
WaylandVsyncSource.h WaylandVsyncSource This class provides a per-widget VsyncSource under Wayland, emulated using frame callbacks on the widget surface with empty surface commits. Wayland does not expose vsync/vblank, as it considers that an implementation detail the clients should not concern themselves with. Instead, frame callbacks are provided whenever the compositor believes it is a good time to start drawing the next frame for a particular surface, giving us as much time as possible to do so. Note that the compositor sends frame callbacks only when it sees fit, and when that may be is entirely up to the compositor. One cannot expect a certain rate of callbacks, or any callbacks at all. Examples of common variations would be surfaces moved between outputs with different refresh rates, and surfaces that are hidden and therefore do not receieve any callbacks at all. Other hypothetical scenarios of variation could be throttling to conserve power, or because a user has requested it. 3285
