void gtk_container_add (GtkContainer *container, GtkWidget *widget); |
Adds widget to container. Typically used for simple containers such as GtkWindow, GtkFrame, or GtkButton; for more complicated layout containers such as GtkBox or GtkTable, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_table_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can't place the same widget inside two different containers.

widget : | a widget to be placed inside container |
void gtk_container_remove (GtkContainer *container, GtkWidget *widget); |
Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it while it's not inside a container, using g_object_ref().

widget : | a current child of container |
void gtk_container_set_resize_mode (GtkContainer *container, GtkResizeMode resize_mode); |
void gtk_container_foreach (GtkContainer *container, GtkCallback callback, gpointer callback_data); |
Invokes callback on each non-internal child of container. See gtk_container_forall() for details on what constitutes an "internal" child. Most applications should use gtk_container_foreach(), rather than gtk_container_forall().

void gtk_container_forall (GtkContainer *container, GtkCallback callback, gpointer callback_data); |
Invokes callback on each child of container, including children that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself. Most applications should use gtk_container_foreach(), rather than gtk_container_forall().

gchar* gtk_container_child_composite_name (GtkContainer *container, GtkWidget *child); |
void gtk_container_set_border_width (GtkContainer *container, guint border_width); |
The border width of a container is the amount of space to leave around the outside of the container. The only exception to this is GtkWindow; because toplevel windows can't leave space outside, they leave the space inside. The border is added on all sides of the container. To add space to only one side, one approach is to create a GtkAlignment widget, call gtk_widget_set_usize() to give it a size, and place it on the side of the container as a spacer.

void gtk_container_dequeue_resize_handler (GtkContainer *container); |
void gtk_container_propagate_expose (GtkContainer *container, GtkWidget *child, GdkEventExpose *event); |
When a container receives an expose event, it must send synthetic expose events to all children that don't have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives an expose event, gtk_container_propagate_expose() once for each child, passing in the event the container received.
gtk_container_propagate expose() takes care of deciding whether an expose event needs to be sent to the child, intersecting the event's area with the child area, and sending the event.
In most cases, a container can simply either simply inherit the ::expose implementation from GtkContainer, or, do some drawing and then chain to the ::expose implementation from GtkContainer.
