GtkHandleBox implements
AtkImplementorIface and GtkBuildable
.
The GtkHandleBox
widget allows a portion of a window to be "torn
off". It is a bin widget which displays its child and a handle that
the user can drag to tear off a separate window (the float
window) containing the child widget. A thin
ghost 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 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
.
GtkHandleBox
The GtkHandleBox
struct contains the following fields.
(These fields should be considered read-only. They should never be set by
an application.)
GtkShadowType shadow_type; | The shadow type for the entry. (See gtkHandleBoxSetShadowType ). |
GtkPositionType handle_position; | The position of the handlebox's handle with respect
to the child. (See gtkHandleBoxSetHandlePosition ) |
gint snap_edge; | A value of type GtkPositiontype indicating snap edge for the widget. (See gtk_handle_box_set_snap_edge). The value of -1 indicates that this value has not been set. |
logicalchild_detached; | A boolean value indicating whether the handlebox's child is attached or detached. |
gtkHandleBox
is the equivalent of gtkHandleBoxNew
.
