/*
* 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.
