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. */ #define MOZ_CONTAINER_TYPE (moz_container_get_type()) #define MOZ_CONTAINER(obj) (G_TYPE_CHECK_INSTANCE_CAST ((obj), MOZ_CONTAINER_TYPE, MozContainer)) #define MOZ_CONTAINER_CLASS(klass) (G_TYPE_CHECK_CLASS_CAST ((klass), MOZ_CONTAINER_TYPE, MozContainerClass)) #define IS_MOZ_CONTAINER(obj) (G_TYPE_CHECK_INSTANCE_TYPE ((obj), MOZ_CONTAINER_TYPE)) #define IS_MOZ_CONTAINER_CLASS(klass) (G_TYPE_CHECK_CLASS_TYPE ((klass), MOZ_CONTAINER_TYPE)) #define MOZ_CONAINTER_GET_CLASS(obj) (G_TYPE_INSTANCE_GET_CLASS ((obj), MOZ_CONTAINER_TYPE, MozContainerClass)) typedef struct _MozContainer MozContainer; typedef struct _MozContainerClass MozContainerClass; struct _MozContainer { GtkContainer container; GList *children; }; struct _MozContainerClass { GtkContainerClass parent_class; }; GType moz_container_get_type (void); GtkWidget *moz_container_new (void); void moz_container_put (MozContainer *container, GtkWidget *child_widget, gint x, gint y); void moz_container_move (MozContainer *container, GtkWidget *child_widget, gint x, gint y, gint width, gint height); #ifdef __cplusplus } #endif /* __cplusplus */ #endif /* __MOZ_CONTAINER_H__ */
