In line 32 the signal "activate" from the action undo_action is connected to the callback function undo_callback() using action.connect(signal, callback function). See for a more detailed explanation.
Use insert(tool_item, position) to insert the tool_item at position. If position is negative, the item is appended at the end of the toolbar.
get_item_index(tool_item) retrieves the position of tool_item on the toolbar.
get_n_items() returns the number of items on the toolbar; get_nth_item(position) returns the item in position position.
If the toolbar does not have room for all the menu items, and set_show_arrow(True), the items that do not have room are shown through an overflow menu.
set_icon_size(icon_size) sets the size of icons in the toolbar; icon_size can be one of Gtk.IconSize.INVALID, Gtk.IconSize.MENU, Gtk.IconSize.SMALL_TOOLBAR, Gtk.IconSize.LARGE_TOOLBAR, Gtk.IconSize.BUTTON, Gtk.IconSize.DND, Gtk.IconSize.DIALOG. This should be used only for special-purpose toolbars, normal application toolbars should respect user preferences for the size of icons. unset_icon_size() unsets the preferences set with set_icon_size(icon_size), so that user preferences are used to determine the icon size.
set_style(style), where style is one of Gtk.ToolbarStyle.ICONS, Gtk.ToolbarStyle.TEXT, Gtk.ToolbarStyle.BOTH, Gtk.ToolbarStyle.BOTH_HORIZ, 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 unset_style().
In this sample we used the following:
GtkToolbar
GtkToolButton
GtkToolItem
Stock Items
GtkActionable
GtkWidget
