/**
 * A #GtkToolPalette allows you to add #GtkToolItems to a palette-like
 * container with different categories and drag and drop support.
 * 
 * A #GtkToolPalette is created with a call to gtk_tool_palette_new().
 * 
 * #GtkToolItems cannot be added directly to a #GtkToolPalette -
 * instead they are added to a #GtkToolItemGroup which can than be added
 * to a #GtkToolPalette. To add a #GtkToolItemGroup to a #GtkToolPalette,
 * use gtk_container_add().
 * 
 * |[<!-- language="C" -->
 * GtkWidget *palette, *group;
 * GtkToolItem *item;
 * 
 * palette = gtk_tool_palette_new ();
 * group = gtk_tool_item_group_new (_("Test Category"));
 * gtk_container_add (GTK_CONTAINER (palette), group);
 * 
 * item = gtk_tool_button_new (NULL, _("_Open"));
 * gtk_tool_button_set_icon_name (GTK_TOOL_BUTTON (item), "document-open");
 * gtk_tool_item_group_insert (GTK_TOOL_ITEM_GROUP (group), item, -1);
 * ]|
 * 
 * The easiest way to use drag and drop with #GtkToolPalette is to call
 * gtk_tool_palette_add_drag_dest() with the desired drag source @palette
 * and the desired drag target @widget. Then gtk_tool_palette_get_drag_item()
 * can be used to get the dragged item in the #GtkWidget::drag-data-received
 * signal handler of the drag target.
