我想在wxPython（没有其他模块）制作游戏，我想制作它以便你可以在游戏开始前在弹出屏幕中输入一些值，然后游戏将在画布上绘制在一个面板上绘制，该面板与主游戏绑定。
我用所有花哨的东西制作了游戏画面（独奏作品） 我做了输入屏幕 但我不能把它们联系起来。
如何启动游戏以便打开一个对话框，然后关闭它打开另一个，然后打开游戏？
我尝试了以下操作，但它不会打开我的画布：
# makes a game by showing 2 dialogs
# after dialogs have been answered, starts the game by drawing the canvas.
# imports
import wx
import Speelveld3
# globals
SCRWIDTH = 950
SCRHEIGHT = 700
# dialogbox class
class MyDialog1(wx.Dialog):
def __init__(self, parent):
wx.Dialog.__init__(self, parent)
self.username = wx.TextCtrl(self)
self.okButton = wx.Button(self, wx.ID_OK, "OK")
class MyDialog2(wx.Dialog):
def __init__(self, parent):
wx.Dialog.__init__(self, parent)
self.canvasWidth = wx.TextCtrl(self)
self.okButton = wx.Button(self, wx.ID_OK, "OK")
# main class
class Game(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, title='My game', size=(SCRWIDTH, SCRHEIGHT))
self.username = ""
self.canvasWidth = 10
# hide the frame for now
self.Hide()
def OnInit(self):
#Make your dialogs
dlg1 = MyDialog1(self)
#if the user pressed "OK" (i.e. NOT "Cancel" or any other button you might add)
if dlg1.ShowModal() == wx.ID_OK:
#get the username from the dialog
self.username = dlg1.username.GetValue()
#clean up the dialog (AFTER you get the username)
dlg1.Destroy()
dlg2 = MyDialog2(self)
#if the user pressed "OK" (i.e. NOT "Cancel" or any other button you might add)
if dlg2.ShowModal() == wx.ID_OK:
#get the username from the dialog
self.canvasWidth = dlg2.canvasWidth.GetValue()
#clean up the dialog (AFTER you get the username)
dlg2.Destroy()
# Now that you have your settings, Make the gameboard
# THIS PART IS STILL BROKEN!
# I can paste the whole board class (structure of it is taken from the tetris tutorial)
# but that seems a bit much tbh...
self.gameBoard = Board.Board(self)
self.gameBoard = SetFocus()
self.gameBoard.start()
self.Centre()
self.Show(True) #show the frame
if __name__ == '__main__':
# how can I start the game here?
app = wx.App()
frame = Game()
board = Speelveld3.Speelveld(frame)
board.start()
frame.Show()
app.MainLoop()

在OnInit中，您只需要在创建Board实例之前调用对话框并以模态方式显示它们。然后它应该正常工作。

你已经double posted了，示例代码中没有任何wx.Dialog告诉我你还没有看过教程，但我会给你带来的好处疑问。
首先，如果要从对话框返回信息，最简单的方法是定义custom dialog。定义一个继承自wx.Dialog的新类，然后将其设置为与普通面板或框架一样。在我看来，你需要其中的两个。它们看起来像这样：
class MyDialog1(wx.Dialog):
def __init__(self, parent):
wx.Dialog.__init__(self, parent)
self.username = wx.TextCtrl(self) #this is where users will enter their username
self.okButton = wx.Button(self, wx.ID_OK, "OK") #Note that I'm using wx.ID_OK. This is important
现在，为了你想要的逻辑。实际上看到的wxPython中的每个对象都有函数Show()和Hide()（API here）。您不希望在对话框完成后显示您的框架，因此在__init__()中，请致电Hide()。我还在初始化一个变量username，这是我将从对话框中存储数据的地方。
class Game(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(SCRWIDTH, SCRHEIGHT))
self.username = ""
self.Hide() #don't show the frame just yet
#self.Hide() is the exact same as self.Show(False)
现在，为您的对话框。就像Mike Driscoll建议的那样，在制作画布之前，你可以调用对话框。使用wx.Dialogs启动ShowModal()。通过将self.okButton的ID设置为常量wx.ID_OK，wxPython会识别出在单击按钮后应关闭对话框。您还应该了解wx.ID_CANCEL。
def OnInit(self):
#Make your dialogs
dlg1 = MyDialog1(self)
if dlg1.ShowModal() == wx.ID_OK:
#if the user pressed "OK" (i.e. NOT "Cancel" or any other button you might add)
self.username = dlg1.username.GetValue() #get the username from the dialog
dlg1.Destroy() #clean up the dialog (AFTER you get the username)
#do this again for your second dialog
#Now that you have your settings, Make the gameboard
self.gameBoard = Board.Board(self)
self.gameBoard = SetFocus()
self.gameBoard.start()
self.Centre()
self.Show(True) #show the frame
