43 * @Short_description: Base class for widgets with two adjustable panes
46 * #GtkPaned is the base class for widgets with two panes, arranged either
47 * horizontally (#GtkHPaned) or vertically (#GtkVPaned). Child widgets are
48 * added to the panes of the widget with gtk_paned_pack1() and
49 * gtk_paned_pack2(). The division between the two children is set by default
50 * from the size requests of the children, but it can be adjusted by the
53 * A paned widget draws a separator between the two child widgets and a
54 * small handle that the user can drag to adjust the division. It does not
55 * draw any relief around the children or around the separator. (The space
56 * in which the separator is called the gutter.) Often, it is useful to put
57 * each child inside a #GtkFrame with the shadow type set to %GTK_SHADOW_IN
58 * so that the gutter appears as a ridge. No separator is drawn if one of
59 * the children is missing.
61 * Each child has two options that can be set, @resize and @shrink. If
62 * @resize is true, then when the #GtkPaned is resized, that child will
63 * expand or shrink along with the paned widget. If @shrink is true, then
64 * that child can be made smaller than its requisition by the user.
65 * Setting @shrink to %FALSE allows the application to set a minimum size.
66 * If @resize is false for both children, then this is treated as if
67 * @resize is true for both children.
69 * The application can set the position of the slider as if it were set
70 * by the user, by calling gtk_paned_set_position().
