一

代码：

#!/usr/bin/env python3
# Created by xiaosanyu at 16/7/3
# section 072

TITLE = "Toolbar"
DESCRIPTION = """
Menus group commands that we can use in application.
Toolbars provide a quick access to the most frequently used commands.
"""
import gi

gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk, Gio


class ToolbarWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="Toolbar Example")

        self.set_size_request(250, 200)
        self.modify_bg(Gtk.StateType.NORMAL, Gdk.color_parse("gray"))
        toolbar = Gtk.Toolbar()
        # 显示图片和文本
        toolbar.set_style(Gtk.ToolbarStyle.BOTH)
        newtb = Gtk.ToolButton(Gtk.STOCK_NEW)
        opentb = Gtk.ToolButton(Gtk.STOCK_OPEN)
        savetb = Gtk.ToolButton(Gtk.STOCK_SAVE)
        sep = Gtk.SeparatorToolItem()
        quittb = Gtk.ToolButton(Gtk.STOCK_QUIT)
        toolbar.insert(newtb, 0)
        toolbar.insert(opentb, 1)

        toolbar.insert(sep, 3)

    win.connect("delete-event", Gtk.main_quit)
    win.show_all()
    Gtk.main()


if __name__ == "__main__":
    main()

代码解析:

toolbar = Gtk.Toolbar()
# 显示图片和文本
toolbar.set_style(Gtk.ToolbarStyle.BOTH)

创建一个Gtk.Toolbar，设置样式为显示文本和图片

newtb = Gtk.ToolButton(Gtk.STOCK_NEW)
opentb = Gtk.ToolButton(Gtk.STOCK_OPEN)
savetb = Gtk.ToolButton(Gtk.STOCK_SAVE)
sep = Gtk.SeparatorToolItem()
quittb = Gtk.ToolButton(Gtk.STOCK_QUIT)

创建四个Gtk.ToolButton和一个分隔线Gtk.SeparatorToolItem

toolbar.insert(newtb, 0)
toolbar.insert(opentb, 1)
toolbar.insert(savetb, 2)
toolbar.insert(sep, 3)
toolbar.insert(quittb, 4)

插入到toolbar中

二弹出菜单

代码

#!/usr/bin/env python3
# Created by xiaosanyu at 16/7/3
# section 073

TITLE = "Popmenu"
DESCRIPTION = """
show Popmenu on the Toolbar
"""
import gi

gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk, Gio, GLib

items = ["EditCopy", "EditPaste", "EditSomething"]


class ToolbarWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="Toolbar Popmenu")

        self.set_size_request(250, 200)
        toolbar = Gtk.Toolbar()
        # 只显示图片
        toolbar.set_style(Gtk.ToolbarStyle.ICONS)
        newtb = Gtk.ToolButton(Gtk.STOCK_NEW)
        opentb = Gtk.ToolButton(Gtk.STOCK_OPEN)
        savetb = Gtk.ToolButton(Gtk.STOCK_SAVE)
        sep = Gtk.SeparatorToolItem()
        quittb = Gtk.ToolButton(Gtk.STOCK_QUIT)
        toolbar.insert(newtb, 0)
        toolbar.insert(opentb, 1)
        toolbar.insert(savetb, 2)
        toolbar.insert(sep, 3)
        toolbar.insert(quittb, 4)
        quittb.connect("clicked", self.on_destroy)

        vbox = Gtk.VBox(False, 2)
        vbox.pack_start(toolbar, False, False, 0)

        menu = Gtk.Menu.new()
        for item in items:
            item = Gtk.MenuItem(label=item)
            item.connect("activate", self.on_menu_selected)
            item.show()
            menu.append(item)
        toolbar.connect("popup_context_menu", self.popmenu, menu)

        self.add(vbox)

    @staticmethod
    def popmenu(toolbar, x, y, button, menu):
        menu.popup(None, None, None, None, button, Gtk.get_current_event_time())

        return True

    @staticmethod
    def on_menu_selected(widget, *args):
        print("Menu item " + widget.get_label() + " was selected")

    def on_destroy(self, widget):
        self.destroy()
        Gtk.main_quit()


def main():
    win = ToolbarWindow()
    win.connect("delete-event", Gtk.main_quit)
    win.show_all()
    Gtk.main()


if __name__ == "__main__":
    main()

代码解析：
基本同例一，就是多了个弹出菜单

三

代码

#!/usr/bin/env python3
# Created by xiaosanyu at 16/7/3
# section 074

TITLE = "Redo & Undo"
DESCRIPTION = """
The following example demonstrates, how we can inactivate toolbar buttons on the toolbar.
It is a common practise in GUI programming. For example the save button.
If we save all changes of our document to the disk, the save button is inactivated in most text editors.
This way the application indicates to the user, that all changes are already saved.
"""
import gi

gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk, Gio


class ToolbarWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="Toolbar Redo & Undo")

        self.set_size_request(250, 200)
        self.modify_bg(Gtk.StateType.NORMAL, Gdk.color_parse("gray"))
        self.count = 2
        toolbar = Gtk.Toolbar()
        # 只显示图片
        toolbar.set_style(Gtk.ToolbarStyle.ICONS)
        self.undo = Gtk.ToolButton(Gtk.STOCK_UNDO)
        self.redo = Gtk.ToolButton(Gtk.STOCK_REDO)
        sep = Gtk.SeparatorToolItem()
        quittb = Gtk.ToolButton(Gtk.STOCK_QUIT)
        toolbar.insert(self.undo, 0)
        toolbar.insert(self.redo, 1)
        toolbar.insert(sep, 2)
        toolbar.insert(quittb, 3)
        self.undo.connect("clicked", self.on_undo)
        self.redo.connect("clicked", self.on_redo)

        vbox.pack_start(toolbar, False, False, 0)
        self.add(vbox)

    def on_undo(self, widget):
        self.count -= 1
        if self.count <= 0:
            self.undo.set_sensitive(False)
            self.redo.set_sensitive(True)

    def on_redo(self, widget):
        self.count += 1
        if self.count >= 5:
            self.redo.set_sensitive(False)
            self.undo.set_sensitive(True)

    def on_destroy(self, widget):
        self.destroy()
        Gtk.main_quit()


def main():
    win = ToolbarWindow()
    win.connect("delete-event", Gtk.main_quit)
    win.show_all()
    Gtk.main()


if __name__ == "__main__":
    main()

这个例子也比较简单，不讲解了

附录

Gtk.ToolbarStyle

class Gtk.ToolbarStyle
Bases: GObject.GEnum

ICONS = 0

只显示图标

TEXT = 1

只显示文本.

BOTH = 2

显示文本和图标

BOTH_HORIZ = 3

文本和图标水平显示而不是垂直.貌似没效果
