"handle-position"	Read-Write	The position of the handle relative to the child widget; one of the GTK Position Type Constants.
"shadow-type"	Read-Write	The type of shadow; one of the GTK Shadow Type Constants.
"snap-edge"	Read-Write	The side of the handlebox that's lined up with the docking point to dock the handlebox; one of the GTK Position Type Constants.
"snap-edge-set"	Read-Write	If `TRUE`, use the value from "snap-edge"; otherwise, use a value derived from "handle-position". Available in GTK+ 2.2 and above.

Description

The gtk.HandleBox 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 into a separate floating window containing the child widget. A thin ghost is drawn in the original location of the handlebox. The separate window can be dragged back to its original location to be reattached. When reattaching, the ghost and float window, must be aligned along one of the edges called the snap edge that can be specified by the application, or specified automatically using a reasonable default based on the handle position. The snap edge is automatically set as gtk.POS_TOP if the handle position is gtk.POS_RIGHT or gtk.POS_LEFT; otherwise, the snap edge will be set as gtk.POS_LEFT.

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 detached. For example, if the handlebox is packed at the bottom of a gtk.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.

Constructor

    gtk.HandleBox()

Returns :

a new handlebox widget

Creates a new gtk.HandleBox widget.

Methods

gtk.HandleBox.set_shadow_type

    def set_shadow_type(type)

type : the shadow type: gtk.SHADOW_NONE, gtk.SHADOW_IN, gtk.SHADOW_OUT, gtk.SHADOW_ETCHED_IN, gtk.SHADOW_ETCHED_OUT

The set_shadow_type() method sets the type of shadow to be drawn around the border of the handle box as specified by type. The value of type must be one of: gtk.SHADOW_NONE, gtk.SHADOW_IN, gtk.SHADOW_OUT, gtk.SHADOW_ETCHED_IN, gtk.SHADOW_ETCHED_OUT.

gtk.HandleBox.get_shadow_type

    def get_shadow_type()

Returns :

the type of shadow currently drawn around the handle box.

The get_shadow_type() method gets the type of shadow drawn around the handle box. The shadow type is one of: gtk.SHADOW_NONE, gtk.SHADOW_IN, gtk.SHADOW_OUT, gtk.SHADOW_ETCHED_IN, gtk.SHADOW_ETCHED_OUT. See set_shadow_type().

gtk.HandleBox.set_handle_position

    def set_handle_position(position)

position : the side of the handlebox where the handle should be drawn.

The set_handle_position() method sets the side of the handlebox where the handle is drawn using the value of position. The value of position must be one of: gtk.POS_LEFT, gtk.POS_RIGHT, gtk.POS_TOP, gtk.POS_BOTTOM

gtk.HandleBox.get_handle_position

    def get_handle_position()

Returns :

the current handle position.

The get_handle_position() method gets the handle position of the handle box; one of: gtk.POS_LEFT, gtk.POS_RIGHT, gtk.POS_TOP, gtk.POS_BOTTOM. See set_handle_position().

gtk.HandleBox.set_snap_edge

    def set_snap_edge(edge)

edge : the edge to use as the snap edge or -1 to have PyGTK automatically pick the snap edge

The set_snap_edge() method sets the snap edge of the handlebox to the value specified by edge. The value of edge can be one of: gtk.POS_LEFT, gtk.POS_RIGHT, gtk.POS_TOP, gtk.POS_BOTTOM or -1 to have the snap edge automatically specified.

The snap edge is the edge of the detached child that must be aligned with the corresponding edge of the "ghost" left behind when the child was detached to reattach the torn-off window. Usually, the snap edge should be chosen so that it stays in the same place on the screen when the handlebox is torn off. If the snap edge is not set, then an appropriate value will be guessed from the handle position. If the handle position is gtk.POS_RIGHT or gtk.POS_LEFT, then the snap edge will be gtk.POS_TOP, otherwise it will be gtk.POS_LEFT.

gtk.HandleBox.get_snap_edge

    def get_snap_edge()

Returns :

the edge used for determining reattachment, or -1 if the snap edge is determined (as per default) from the handle position.

The get_snap_edge() method gets the edge used for determining reattachment of the handle box. The return value will be one of: gtk.POS_LEFT, gtk.POS_RIGHT, gtk.POS_TOP, gtk.POS_BOTTOM or -1 to indicate the snap edge is automatically selected. See set_snap_edge().

Signals

The "child-attached" gtk.HandleBox Signal

    def callback(handlebox, widget, user_param1, ...)

`handlebox` :	the widget that received the signal
`widget` :	the child widget
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "child-attached" signal is emitted when the contents of the handlebox are reattached to the main window.

The "child-detached" gtk.HandleBox Signal

    def callback(handlebox, widget, user_param1, ...)

`handlebox` :	the widget that received the signal
`widget` :	the child widget
`user_param1` :	the first user parameter (if any) specified with the `connect`() method
`...` :	additional user parameters (if any)

The "child-detached" signal is emitted when the contents of the handlebox are detached from the main window.
