# Package Gtk.Paned

A Gtk_Paned is a container that organizes its two children either horizontally or vertically. The initial size allocated to the children depends on the size they request. However, the user has the possibility to interactively move a separation bar between the two to enlarge one of the children, while at the same time shrinking the second one. The bar can be moved by clicking with the mouse on a small cursor displayed in the bar, and then dragging the mouse.

No additional decoration is provided around the children.

Each child has two parameters, Resize and Shrink.

If Shrink is True, then the widget can be made smaller than its requisition size by the user. Set this to False if you want to set a minimum size.

if Resize is True, this means that the child accepts to be resized, and will not require any size. Thus, the size allocated to it will be the total size allocated to the container minus the size requested by the other child. If Resize is False, the child should ask for a specific size, which it will get. The other child will be resized accordingly. If both Child have the same value for Resize (either True or False), then the size allocated to each is a ratio between the size requested by both.

When you use Set_Position with a parameter other than -1, or the user moves the handle to resize the widgets, the behavior of Resize is canceled.

## Subprograms

    procedure Gtk_New_Vpaned
      (Widget             : out    Gtk_Paned);
| Create a new vertical container. The children will be displayed one on top of the other.
    procedure Gtk_New_Hpaned
      (Widget             : out    Gtk_Paned);
| Create a new horizontal container. The children will be displayed one besides the other.
    procedure Initialize_Vpaned
      (Widget             : access Gtk_Paned_Record'Class);
| Internal initialization function. See the section "Creating your own widgets" in the documentation.
    procedure Initialize_Hpaned
      (Widget             : access Gtk_Paned_Record'Class);
| Internal initialization function. See the section "Creating your own widgets" in the documentation.
    function Get_Type              return Glib.GType;
| Return the internal value associated with a Gtk_Paned.
    function Get_Type_Vpaned       return Glib.GType;
| Return the internal value associated with a vertical Gtk_Paned.
    function Get_Type_Hpaned       return Glib.GType;
| Return the internal value associated with a horizontal Gtk_Paned.
    procedure Add1
      (Paned              : access Gtk_Paned_Record;
       Child              : access Gtk_Widget_Record'Class);
| Add the first child of the container. The child will be displayed either in the top or in the left pane, depending on the orientation of the container. This is equivalent to using the Pack1 procedure with its default parameters.
    procedure Pack1
      (Paned              : access Gtk_Paned_Record;
       Child              : access Gtk_Widget_Record'Class;
       Resize             :        Boolean := False;
       Shrink             :        Boolean := True);
| Add a child to the top or left pane. You can not change dynamically the attributes Resize and Shrink. Instead, you have to remove the child from the container, and put it back with the new value of the attributes. You should also first call Gtk.Object.Ref on the child so as to be sure it is not destroyed when you remove it, and Gtk.Object.Unref it at the end. See the example in testgtk/ in the GtkAda distribution.
    procedure Add2
      (Paned              : access Gtk_Paned_Record;
       Child              : access Gtk_Widget_Record'Class);
| Add the second child of the container. It will be displayed in the bottom or right pane, depending on the container's orientation. This is equivalent to using Pack2 with its default parameters.
    procedure Pack2
      (Paned              : access Gtk_Paned_Record;
       Child              : access Gtk_Widget_Record'Class;
       Resize             :        Boolean := False;
       Shrink             :        Boolean := False);
| Add a child to the bottom or right pane.
    function Get_Position
      (Paned              : access Gtk_Paned_Record)
       return Gint;
| Return the position of the separator.
    procedure Set_Position
      (Paned              : access Gtk_Paned_Record;
       Position           :        Gint);
| Change the position of the separator. If position is negative, the remembered position is forgotten, and the division is recomputed from the requisitions of the children. Position is in fact the size (either vertically or horizontally, depending on the container) set for the first child.
    function Get_Child1
      (Paned              : access Gtk_Paned_Record)
       return Gtk.Widget.Gtk_Widget;
| Return the child displayed in the top or left pane.
    function Get_Child2
      (Paned              : access Gtk_Paned_Record)
       return Gtk.Widget.Gtk_Widget;
| Return the child displayed in the bottom or right pane.
    function Get_Child1_Resize
      (Paned              : access Gtk_Paned_Record)
       return Boolean;
| Get the value of the resize attribute for the first child.
    function Get_Child2_Resize
      (Paned              : access Gtk_Paned_Record)
       return Boolean;
| Get the value of the resize attribute for the second child.
    function Get_Child1_Shrink
      (Paned              : access Gtk_Paned_Record)
       return Boolean;
| Get the value of the shrink attribute for the first child.
    function Get_Child2_Shrink
      (Paned              : access Gtk_Paned_Record)
       return Boolean;
| Get the value of the shrink attribute for the second child.
