It is a bin widget which displays its child and a handle that + * the user can drag to tear off a separate window (the <firstterm>float + * window</firstterm>) containing the child widget. A thin + * <firstterm>ghost</firstterm> is drawn in the original location of the + * handlebox. By dragging the separate window back to its original + * location, it can be reattached. + * + * When reattaching, the ghost and float window, must be aligned + * along one of the edges, the <firstterm>snap edge</firstterm>. + * This either can be specified by the application programmer + * explicitely, or GTK+ will pick a reasonable default based + * on the handle position. + * + * To make detaching and reattaching the handlebox as minimally confusing + * as possible to the user, it is important to set the snap edge so that + * the snap edge does not move when the handlebox is deattached. For + * instance, if the handlebox is packed at the bottom of a VBox, then + * when the handlebox is detached, the bottom edge of the handlebox's + * allocation will remain fixed as the height of the handlebox shrinks, + * so the snap edge should be set to %GTK_POS_BOTTOM. + * + * <note> + * #GtkHandleBox has been deprecated. It is very specialized, lacks features + * to make it useful and most importantly does not fit well into modern + * application design. Do not use it. There is no replacement. + * </note> + */ + + +struct _GtkHandleBoxPrivate +{ + /* Properties */ + GtkPositionType handle_position; + GtkPositionType snap_edge; + GtkShadowType shadow_type; + gboolean child_detached; + /* Properties */ + + GtkAllocation attach_allocation; + GtkAllocation float_allocation; + + GdkDevice *grab_device; + + GdkWindow *bin_window; /* parent window for children */ + GdkWindow *float_window; + + /* Variables used during a drag + */ + gint orig_x; + gint orig_y; + + guint float_window_mapped : 1; + guint in_drag : 1; + guint shrink_on_detach : 1; +}; + +enum { + PROP_0, + PROP_SHADOW_TYPE, + PROP_HANDLE_POSITION, + PROP_SNAP_EDGE, + PROP_SNAP_EDGE_SET, + PROP_CHILD_DETACHED +}; + +#define DRAG_HANDLE_SIZE 10 +#define CHILDLESS_SIZE 25 +#define GHOST_HEIGHT 3 +#define TOLERANCE 5 + +enum { + SIGNAL_CHILD_ATTACHED, + SIGNAL_CHILD_DETACHED, + SIGNAL_LAST +}; + +/* The algorithm for docking and redocking implemented here + * has a couple of nice properties: + * + * 1) During a single drag, docking always occurs at the + * the same cursor position.
