The division between + * the two panes is adjustable by the user by dragging + * a handle. + * + * Child widgets are + * added to the panes of the widget with gtk_paned_pack1() and + * gtk_paned_pack2(). The division between 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. No separator is drawn if one of + * the children is missing. + * + * 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 + * 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(). + * + * + * Creating a paned widget with minimum sizes. + * + * GtkWidget *hpaned = gtk_paned_new (GTK_ORIENTATION_HORIZONTAL);
