更改 window/frame gtk3 pygtk 并传递参数

Question

我用 pygtk 创建了一个简单的游戏，它从开始页面（选项、新游戏、ecc）开始，当我按下新游戏按钮时，我想更改 window/frame 并替换为游戏 window . 这是一个代码示例：

import gi

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


class MainWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="Title of Window")
        self.set_border_width(20)
        layout = Gtk.Box(spacing=10)
        self.add(layout)
        self.set_default_size(300, 500)

        label_start = Gtk.Label("This is start page")
        layout.pack_start(label_start, True, True, 0)

        new_game_button = Gtk.Button("NEW GAME")
        new_game_button.connect("clicked", self.start_new_game)
        new_game_button.set_border_width(20)
        new_game_button.set_valign(Gtk.Align.CENTER)
        layout.pack_start(new_game_button, True, True, 0)

    def start_new_game(self, widget):
        # here is were i want to go to first page
        pass


class FirstPage(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="Title of Window")
        self.set_border_width(20)
        layout = Gtk.Box(spacing=10)
        self.add(layout)
        self.set_default_size(300, 500)

        label_start = Gtk.Label("This is start page")
        layout.pack_start(label_start, True, True, 0)

        return_button = Gtk.Button("NEW GAME")
        return_button.connect("clicked", self.return_start_page)
        return_button.set_border_width(20)
        return_button.set_valign(Gtk.Align.CENTER)
        layout.pack_start(return_button, True, True, 0)


def return_start_page(self, widget):
    # here is were i want to manage the event to return to start page
    pass


window = MainWindow()
window.connect("delete-event", Gtk.main_quit)
window.show_all()
Gtk.main()

"start new game" 和 "return start page" 是我想要管理此事件的方法。我还需要将其他参数传递给新游戏。我可以简单地将它们添加到游戏 window 的 init 吗？ PS："game window" 是示例中的 MainWindow，FirstPage 代表我的 "start page"，带有选项菜单和其他东西。

解决方案

你应该只创建一个 Main window 和一个 Gtk.Box（作为容器），2 个 "screens" 应该是 2 个额外的Gtk.Box在集装箱箱子里。例如：

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


class MainWindow(Gtk.Window):
    def __init__(self):
        super(MainWindow, self).__init__(title="Title of Window")
        self.set_border_width(20)
        self.set_default_size(300, 500)

        container = Gtk.Box()
        self.add(container)
        container.show()

        self.main = Main(self)
        container.add(self.main)

        self.first_page = FirstPage(self)
        container.add(self.first_page)


class Main(Gtk.Box):
    def __init__(self, parent_window):
        super().__init__(spacing=10)
        self.__parent_window = parent_window

        label_start = Gtk.Label("This is start page")
        self.pack_start(label_start, True, True, 0)

        new_game_button = Gtk.Button("NEW GAME")
        new_game_button.connect("clicked", self.start_new_game)
        new_game_button.set_border_width(20)
        new_game_button.set_valign(Gtk.Align.CENTER)
        self.pack_start(new_game_button, True, True, 0)

    def start_new_game(self, *args):
        self.__parent_window.first_page.show_all()
        self.hide()


class FirstPage(Gtk.Box):
    def __init__(self, parent_window):
        super().__init__(spacing=10)
        self.__parent_window = parent_window

        label_start = Gtk.Label("This is second page")
        self.pack_start(label_start, True, True, 0)

        return_button = Gtk.Button("END GAME")
        return_button.connect("clicked", self.return_start_page)
        return_button.set_border_width(20)
        return_button.set_valign(Gtk.Align.CENTER)
        self.pack_start(return_button, True, True, 0)

    def return_start_page(self, *args):
        self.__parent_window.main.show_all()
        self.hide()


if __name__ == '__main__':
    window = MainWindow()
    window.connect("delete-event", Gtk.main_quit)
    window.main.start_new_game()
    window.show()
    Gtk.main()

备选方案

您可以使用 Gtk.Notebook 和切换标签。例如：

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


class MainWindow(Gtk.Window):
    def __init__(self):
        super(MainWindow, self).__init__(title="Title of Window")
        self.set_border_width(20)
        self.set_default_size(300, 500)

        container = Gtk.Notebook()
        container.set_show_tabs(False)
        self.add(container)

        main = Main(container)
        container.append_page(main)

        first_page = FirstPage(container)
        container.append_page(first_page)


class Main(Gtk.Box):
    def __init__(self, parent):
        super().__init__(spacing=10)
        self.__parent = parent

        label_start = Gtk.Label("This is start page")
        self.pack_start(label_start, True, True, 0)

        new_game_button = Gtk.Button("NEW GAME")
        new_game_button.connect("clicked", self.start_new_game)
        new_game_button.set_border_width(20)
        new_game_button.set_valign(Gtk.Align.CENTER)
        self.pack_start(new_game_button, True, True, 0)

    def start_new_game(self, widget):
        self.__parent.set_current_page(1)


class FirstPage(Gtk.Box):
    def __init__(self, parent):
        super().__init__(spacing=10)
        self.__parent = parent

        label_start = Gtk.Label("This is second page")
        self.pack_start(label_start, True, True, 0)

        return_button = Gtk.Button("END GAME")
        return_button.connect("clicked", self.return_start_page)
        return_button.set_border_width(20)
        return_button.set_valign(Gtk.Align.CENTER)
        self.pack_start(return_button, True, True, 0)

    def return_start_page(self, widget):
        self.__parent.set_current_page(0)


if __name__ == '__main__':
    window = MainWindow()
    window.connect("delete-event", Gtk.main_quit)
    window.show_all()
    Gtk.main()
