Detailed Description

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.

Structures

Convenient Construction

gtkHandleBox is the equivalent of gtkHandleBoxNew.

Signals

child-attached(handlebox, widget, user.data)
This signal is emitted when the contents of the handlebox are reattached to the main window.
handlebox
the object which received the signal.
widget
the child widget of the handlebox. (this argument provides no extra information and is here only for backwards-compatibility)
user.data
user data set when the signal handler was connected.
child-detached(handlebox, widget, user.data)
This signal is emitted when the contents of the handlebox are detached from the main window.
handlebox
the object which received the signal.
widget
the child widget of the handlebox. (this argument provides no extra information and is here only for backwards-compatibility)
user.data
user data set when the signal handler was connected.

Properties

child-detached [logical : Read]
A boolean value indicating whether the handlebox's child is attached or detached. Default value: FALSE
handle-position [GtkPositionType : Read / Write]
Position of the handle relative to the child widget. Default value: GTK_POS_LEFT
shadow [GtkShadowType : Read / Write]
Deprecated property, use shadow_type instead. Default value: GTK_SHADOW_OUT
shadow-type [GtkShadowType : Read / Write]
Appearance of the shadow that surrounds the container. Default value: GTK_SHADOW_OUT
snap-edge [GtkPositionType : Read / Write]
Side of the handlebox that's lined up with the docking point to dock the handlebox. Default value: GTK_POS_TOP
snap-edge-set [logical : Read / Write]
Whether to use the value from the snap_edge property or a value derived from handle_position. Default value: FALSE
