    <title>Useful methods for a Toolbar widget</title>

    <list>
      <item><p>Use <code>insert(tool_item, position)</code> to insert the <code>tool_item</code> at <code>position</code>. If <code>position</code> is negative, the item is appended at the end of the toolbar.</p></item>
      <item><p><code>get_item_index(tool_item)</code> retrieves the position of <code>tool_item</code> on the toolbar.</p></item>
      <item><p><code>get_n_items()</code> returns the number of items on the toolbar; <code>get_nth_item(position)</code> returns the item in position <code>position</code>.</p></item>
      <item><p>If the toolbar does not have room for all the menu items, and <code>set_show_arrow(True)</code>, the items that do not have room are shown through an overflow menu.</p></item>
      <item><p><code>set_icon_size(icon_size)</code> sets the size of icons in the toolbar; <code>icon_size</code> can be one of <code>Gtk.IconSize.INVALID, Gtk.IconSize.MENU, Gtk.IconSize.SMALL_TOOLBAR, Gtk.IconSize.LARGE_TOOLBAR, Gtk.IconSize.BUTTON, Gtk.IconSize.DND, Gtk.IconSize.DIALOG</code>. This should be used only for special-purpose toolbars, normal application toolbars should respect user preferences for the size of icons. <code>unset_icon_size()</code> unsets the preferences set with <code>set_icon_size(icon_size)</code>, so that user preferences are used to determine the icon size.</p></item>
      <item><p><code>set_style(style)</code>, where <code>style</code> is one of <code>Gtk.ToolbarStyle.ICONS, Gtk.ToolbarStyle.TEXT, Gtk.ToolbarStyle.BOTH, Gtk.ToolbarStyle.BOTH_HORIZ</code>, sets if the toolbar shows only icons, only text, or both (vertically stacked or alongside each other). To let user preferences determine the toolbar style, and unset a toolbar style so set, use <code>unset_style()</code>.</p></item>
