Package: Handle_Box

- Goto spec source

# Description

    package Gtk.Handle_Box is

The Gtk_Handle_Box 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 GtkAda 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 detached. 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 Pos_Bottom.

Binding from C File version 2.16.6

# Subprograms & Entries

### Gtk_New

- Goto spec in source

    procedure Gtk_New (Handle_Box: out Gtk_Handle_Box);

Create a new Handle_Box.

### Initialize

- Goto spec in source

    procedure Initialize (Handle_Box: access Gtk_Handle_Box_Record'Class);

Internal initialization function. See the section "Creating your own widgets" in the documentation.

### Get_Type

- Goto spec in source
- Goto body in source

    function Get_Type return Gtk.Gtk_Type;

Return the internal value associated with a Gtk_Dialog.

### Set_Shadow_Type

- Goto spec in source

    procedure Set_Shadow_Type (Handle_Box: access Gtk_Handle_Box_Record;Typ: Enums.Gtk_Shadow_Type);

### Get_Shadow_Type

- Goto spec in source

    function Get_Shadow_Type (Handle_Box: access Gtk_Handle_Box_Record) return Enums.Gtk_Shadow_Type;

Sets or gets the type of shadow to be drawn around the border of the Handle_Box.

### Set_Handle_Position

- Goto spec in source

    procedure Set_Handle_Position (Handle_Box: access  Gtk_Handle_Box_Record;Position: Enums.Gtk_Position_Type);

### Get_Handle_Position

- Goto spec in source

    function Get_Handle_Position (Handle_Box: access  Gtk_Handle_Box_Record) return Enums.Gtk_Position_Type;

Sets or gets the side of the Handle_Box where the handle is drawn.

### Set_Snap_Edge

- Goto spec in source

    procedure Set_Snap_Edge (Handle_Box: access  Gtk_Handle_Box_Record;Edge: Enums.Gtk_Position_Type);

### Get_Snap_Edge

- Goto spec in source

    function Get_Snap_Edge (Handle_Box: access  Gtk_Handle_Box_Record) return Enums.Gtk_Position_Type;

Sets or gets the snap edge of a Handle_Box. 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 Handle_Box 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 Pos_Right or Pos_Left, then the snap edge will be Pos_Top, otherwise it will be Pos_Left.

### Get_Child_Detached

- Goto spec in source

    function Get_Child_Detached (Handle_Box: access Gtk_Handle_Box_Record) return Boolean;

Returns whether the handlebox's child is currently detached.
