【问题描述】：

在哪里以及如何让它更新或刷新？？？

如果我按下底部按钮(button1, button2, button3)，我想更改上下文、位置等。

但我不知道怎么做。你能帮我一下吗？？？

代码如下：

import wx


class mainFrame(wx.Frame):
    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent, id, "refresh&update", size=(900,600))

        self.count = 0

        if self.count == 0:
            self.text = wx.TextCtrl(self,  pos=(0, 0), size=(100, 100))
            self.text.AppendText('00000000')

            self.text1 = wx.TextCtrl(self,  pos=(100, 100), size=(100, 100))
            self.text1.AppendText('00000000')

            self.text2 = wx.TextCtrl(self,  pos=(170, 250), size=(100, 100))
            self.text2.AppendText('00000000')

        if self.count == 1:
            self.text3 = wx.TextCtrl(self,  pos=(100, 50), size=(100, 100))
            self.text3.AppendText('1111111')

            buttonl = wx.Button(self, label="1111111", pos=(450,100), size=(100,100))
            button2 = wx.Button(self, label="1111111", pos=(250,100), size=(100,100))

        if self.count == 2:
            self.text6 = wx.TextCtrl(self,  pos=(0, 0), size=(100, 100))
            self.text6.AppendText('22222222')

            self.text = wx.TextCtrl(self,  pos=(100, 100), size=(100, 100))
            self.text.AppendText('22222222')

            button3 = wx.Button(self, label="22", pos=(250,170), size=(100,100))
            button4 = wx.Button(self, label="22", pos=(350,170), size=(100,100))



        button1 = wx.Button(self, label="count0", pos=(150,450), size=(200,100))
        button1.Bind(wx.EVT_BUTTON, self.OnB1)


        button2 = wx.Button(self, label="count1", pos=(400,450), size=(200,100))
        button2.Bind(wx.EVT_BUTTON, self.OnB2)


        button3 = wx.Button(self, label="count2", pos=(650,450), size=(200,100))
        button3.Bind(wx.EVT_BUTTON, self.OnB3)



    def OnB1(self, event):
        self.count = 0

    def OnB2(self, event):
        self.count = 1

    def OnB3(self, event):
        self.count = 2


app = wx.App()
frame = mainFrame(None, id = -1).Show()
app.MainLoop()

但是在这个数组中，我没有发现如何

self.counts = [

                        image=wx.Image(u"aaa.jpg",wx.BITMAP_TYPE_ANY),
                        self.bitmap_1 = wx.StaticBitmap(self, wx.ID_ANY, wx.BitmapFromImage(image.Rescale(350, 350)), (490,420)),
                        self.bitmap_1.Bind(wx.EVT_LEFT_DOWN, self.onClick,
                    ],
                    [ #count = 1
                        button_cancel = wx.Button(self, label="취소", pos=(490,550), size=(300,150)),
                        button_cancel.SetFont(wx.Font(40, wx.ROMAN, wx.SLANT, wx.BOLD, 0, "")),
                    ],
                ]

【解决方案1】：

您只是更改变量count。 __init__ 被调用一次。没有新的文本被追加改变或任何东西，只有变量计数被改变。在您的按钮侦听器中，您需要添加代码来更改文本。

在OnB* 函数中：

def OnB1(self, event):
    self.count = 0
    self.text.SetLabel("%06d"%self.count)

【讨论】：

或者更简单的self.text.SetLabel("%06d"%self.count)
@JoranBeasley：是的，也许我不应该回答这些问题，因为我缺乏使用 wxWidgets 的经验。哈哈。谢谢！
@JoranBeasley:@Bair：非常感谢。我明白为什么它不起作用。但我找不到正确的答案。如何创建按钮 1、按钮 2、按钮 3、按钮 4？按照您的 OnB* 代码，它只能更改文本。我想做按钮和不相关的 text.SetLabel(OnB1 -> text.AppendText('1235535'))。
什么？我不明白你在问什么
@Joran Beasley ：我的意思是我怎样才能使它正确或工作。不可能？？？你能教我一些可以用几个按钮改变的代码吗？

非常感谢^^。你的回答对我很有帮助。我可以再问一件事吗？我试图应用我的代码。但我在 self.counts[] 中有一些错误（我的问题代码底部有错误代码）。
