Question

通过我的代码，我现在已经决定在按钮和背景改变的位置之间需要多个屏幕我认为最简单的方法是通过定义面板类，然后创建一个框架，但我不知道如何在框架上将所有面板链接在一起。我知道每个面板上我想要哪些按钮和图像，但我不知道你如何定义面板并通过点击按钮链接它们

import os
import pygame
import wx
import os
import game

class MainPanel(wx.Panel):
    def __init__(self,parent,id):
        image_file='main_screen.jpg'#loading an image file from the folder
        bmp=wx.Bitmap(image_file)
        self.bitmap = wx.StaticBitmap(self, wx.ID_ANY, bmp, (0, 0))

        PlayButton=wx.Bitmap('play.jpg', wx.BITMAP_TYPE_ANY)
        self.PlayButton=wx.BitmapButton(self.bitmap, -1, PlayButton, pos=(190,300))
        self.PlayButton.Bind=(wx.EVT_BUTTON, self.opengame)

        RulesButton=wx.Bitmap('rules.jpg', wx.BITMAP_TYPE_ANY)
        self.RulesButton=wx.BitmapButton(self.bitmap, -1, RulesButton, pos=(190,370))
        self.RulesButton.Bind=(wx.EVT_BUTTON, self.openrules)

        ControlsButton=wx.Bitmap('controls.jpg', wx.BITMAP_TYPE_ANY)
        self.ControlsButton=wx.BitmapButton(self.bitmap, -1, ControlsButton, pos=(190,440))
        #self.ControlsButton.Bind=(wx.EVT_BUTTON, self.closeMe)

        ExitButton=wx.Bitmap('exit.jpg', wx.BITMAP_TYPE_ANY)
        self.ExitButton=wx.BitmapButton(self.bitmap,-1,ExitButton,pos=(190,510))
        self.ExitButton.Bind(wx.EVT_BUTTON, self.closeexit) 

        self.Bind(wx.EVT_CLOSE, self.closewindow)

class ControlPanel(wx.Panel):
    def __init__(self,parent,id):
        wx.Panel.__init__(self, parent, id=wx.ID_ANY)
        image_file='controls.jpg'#loading an image file from the folder
        bmp=wx.Bitmap(image_file)
        self.bitmap2 = wx.StaticBitmap(self, wx.ID_ANY, bmp, (0, 0))

        BackButton=wx.Bitmap('back.jpg',wx.BITMAP_TYPE_ANY)
        self.BackButton=wx.BitmapButton(self.bitmap2,-1,BackButton, pos=400,100)
        self.BackButton.Bind=(wx.EVT_BUTTON, self.goback)

class RulesPanel(wx.Panel):
    def __init__(self,parent,id):
        wx.Panel.__init__(self, parent, id=wx.ID_ANY)
        image_file='rules.jpg'#loading an image file from the folder
        bmp=wx.Bitmap(image_file)
        self.bitmap3 = wx.StaticBitmap(self, wx.ID_ANY, bmp, (0, 0))

        BackButton=wx.Bitmap('back.jpg',wx.BITMAP_TYPE_ANY)
        self.BackButton=wx.BitmapButton(self.bitmap3,-1,BackButton, pos=400,100)
        self.BackButton.Bind=(wx.EVT_BUTTON, self.goback)

class MainFrame(wx.Frame):
    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Compsci Vs. Sheep: The Game',size=(640,640))

    def openrules(self,event):


    def opengame(self):
    game.start()

    def opencontrols(self,event):
    ?
    def goback(self,event):
    ?
    def closewindow(self,event):
    self.Destroy()
    pygame.mixer.quit()
def closeexit

if __name__=='__main__':
    pygame.mixer.init(frequency=22050, size=-16, channels=2, buffer=4096)
    pygame.mixer.music.load("exorcist.ogg")
    pygame.mixer.music.play(-1)#music playing in program
    app=wx.PySimpleApp()
    frame=menu(parent=None,id=-1)
    frame.Show()#shows the screen
    app.MainLoop()

这是我的新代码仍无效

import os
import pygame

def switch_to(name):
    print "Pseudo switch",name



class MainFrame(wx.Frame):
    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Compsci Vs. Sheep: The Game',size=(640,640))

        self.box = wx.BoxSizer()

        self._panels = {}
        self._panels['main'] = MainPanel(self, -1)
        self._panels['rules'] = RulesPanel(self, -1)
        self._panels['rules'].Hide()

        self.box.Add(self._panels['main'],1,wx.EXPAND)
        self.box.Add(self._panels['rules'],1,wx.EXPAND)

        self.SetSizer(self.box)

    def switch_panel(self, name):
        print "Switching to",name
        return
        for key, panel in self._panels.iteritems():
            if key != name:
                panel.Hide()
            else:
                panel.Show(True)        
        self.Layout()

class MainPanel(wx.Panel):
    def __init__(self,parent,id):
        wx.Panel.__init__(self,parent,id=wx.ID_ANY)
        image_file='main_screen.jpg'#loading an image file from the folder
        bmp=wx.Bitmap(image_file)
        self.bitmap = wx.StaticBitmap(self, wx.ID_ANY, bmp, (0, 0))

        PlayButton=wx.Bitmap('play.jpg', wx.BITMAP_TYPE_ANY)
        self.PlayButton=wx.BitmapButton(self,-1, PlayButton, (190,300), (244,60))

        RulesButton=wx.Bitmap('rules.jpg', wx.BITMAP_TYPE_ANY)
        self.RulesButton=wx.BitmapButton(self, -1, RulesButton, (190,300), (244,60))
        self.RulesButton.Bind=(wx.EVT_BUTTON, parent.switch_panel)

class RulesPanel(wx.Panel):
    def __init__(self,parent,id):
        wx.Panel.__init__(self, parent, id=wx.ID_ANY)
        image_file='rules.jpg'#loading an image file from the folder
        bmp=wx.Bitmap(image_file)
        self.bitmap = wx.StaticBitmap(self, wx.ID_ANY, bmp, (0, 0))

    pygame.mixer.music.play(-1)#music playing in program
    app = wx.PySimpleApp()

    frame.Show()#shows the screen

您可以在框架构造函数中创建所有面板并将它们放在字典中。然后你可以创建一个名为switch_panel的函数，它隐藏除了你想要显示的面板之外的所有面板。例如：

def MyFrame(wx.Frame):
    # Dict for storing the panels.
    _panels = {}

    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent, id, 'Example')

        # Create all the panels.
        self._panels['main'] = MainPanel(self, -1)
        self._panels['control'] = ControlPanel(self, -1)
        self._panels['rules'] = RulesPanel(self, -1)

        # Hide all the panels initially.
        for key, panel in self._panels.iteritems():
            panel.Hide()

        # Show the main panel.
        self.switch_panel('main')

    def switch_panel(self, name):
        """Function for switching between the frame's panels."""
        for key, panel in self._panels.iteritems():
            if key != name:
                panel.Hide()
            else:
                panel.Show(True)

现在，只要您使用“主要”，“控制”或“规则”致电switch_panel，就会显示该面板，其他面板将被隐藏。

如何在按钮上点击switch_panel？

将事件处理程序绑定到按钮，例如

my_button = wx.Button(self, -1, 'Click me!')

my_button.bind(
    wx.EVT_BUTTON,
    lambda e: self.switch_panel('control')
)

面板类和它们之间的切换
