When reattaching, the ghost and float window, must be aligned along one of the edges, the snap edge. 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.
position can be one of: GTK_POS_LEFT, GTK_POS_RIGHT, GTK_POS_TOP, GTK_POS_BOTTOM.
type can be one of: GTK_SHADOW_NONE, GTK_SHADOW_IN, GTK_SHADOW_OUT, GTK_SHADOW_ETCHED_IN, GTK_SHADOW_ETCHED_OUT.
