## Description

GtkPaned is the base class for widgets with two panes, arranged either horizontally (GtkHPaned) or vertically (GtkVPaned). Child widgets are added to the panes of the widget with `gtk_paned_pack1()` and `gtk_paned_pack2()`. The division beween the two children is set by default from the size requests of the children, but it can be adjusted by the user.

A paned widget draws a separator between the two child widgets and a small handle that the user can drag to adjust the division. It does not draw any relief around the children or around the separator. (The space in which the separator is called the gutter.) Often, it is useful to put each child inside a GtkFrame with the shadow type set to `GTK_SHADOW_IN` so that the gutter appears as a ridge.

Each child has two options that can be set, `resize` and `shrink`. If `resize` is true, then when the GtkPaned is resized, that child will expand or shrink along with the paned widget. If `shrink` is true, then when that child can be made smaller than its requisition by the user. Setting `shrink` to `FALSE` allows the application to set a minimum size. If `resize` is false for both children, then this is treated as if `resize` is true for both children.

The application can set the position of the slider as if it were set by the user, by calling `gtk_paned_set_position()`.

Example 35. Creating a paned widget with minimum sizes.

    GtkWidget *hpaned = gtk_hpaned_new ();
    GtkWidget *frame1 = gtk_frame_new (NULL);
    GtkWidget *frame2 = gtk_frame_new (NULL);
    gtk_frame_set_shadow_type (GTK_FRAME (frame1), GTK_SHADOW_IN);
    gtk_frame_set_shadow_type (GTK_FRAME (frame2), GTK_SHADOW_IN);

    gtk_widget_set_size_request (hpaned, 200 + GTK_PANED (hpaned)->gutter_size, -1);

    gtk_paned_pack1 (GTK_PANED (hpaned), frame1, TRUE, FALSE);
    gtk_widget_set_size_request (frame1, 50, -1);

    gtk_paned_pack2 (GTK_PANED (hpaned), frame2, FALSE, FALSE);
    gtk_widget_set_size_request (frame2, 50, -1);
