如何使python更新或刷新？？？（wxpython）

在哪里以及如何使其更新或刷新

如果我按下底部的按钮（按钮1、按钮2、按钮3），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()

但在这个数组中，我没有发现如何

self.counts = [
                    [ #count =0
                        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, "")),
                    ],
                ]

您只需更改变量

计数

<代码>\uuuu init\uuuu只调用一次。没有添加新文本或任何更改，只更改了变量计数。在按钮侦听器中，您需要添加代码来更改文本

在

OnB*

功能中：

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

也许你在找这样的东西

import wx

def BoundButton(*args,**kwargs):
    callback = kwargs.pop("callback",lambda e:None)
    btn = wx.Button(*args,**kwargs)
    btn.Bind(wx.EVT_BUTTON,callback)
    return btn

def hide_all(itm):
    if isinstance(itm,(list,tuple)):
        for i in itm:
            hide_all(i)
    else:
        itm.Hide()

def show_all(itm):
    if isinstance(itm,(list,tuple)):
        for i in itm:
            show_all(i)
    else:
        itm.Show()

class mainFrame(wx.Frame):
    def __init__(self):

        wx.Frame.__init__(self, None, -1, "refresh&update", size=(900,600))
        self.count = 0
        self.counts = [
            [ #count =0
                wx.TextCtrl(self,-1,'{0:08d}'.format(0),  pos=(0, 0), size=(100, 100)),
                wx.TextCtrl(self,-1,'{0:08d}'.format(0),  pos=(100, 100), size=(100, 100)),
                wx.TextCtrl(self,-1,'{0:08d}'.format(0),  pos=(170, 250), size=(100, 100)),
                BoundButton(self, label="count0", pos=(150,450), size=(200,100),callback=self.OnB1),
                BoundButton(self, label="count1", pos=(400,450), size=(200,100),callback=self.OnB1),
                BoundButton(self, label="count2", pos=(650,450), size=(200,100),callback=self.OnB1),
            ],
            [ #count = 1
                 wx.TextCtrl(self,-1,"{0:08d}".format(1),  pos=(100, 50), size=(100, 100)),
                 BoundButton(self, label="1111111", pos=(450,100), size=(100,100),callback=self.OnB2),
                 BoundButton(self, label="1111111", pos=(250,100), size=(100,100),callback=self.OnB2),
            ],

        ]
        self.updateFromCount()
    def OnB1(self,e):
        self.Toggle(1)
    def OnB2(self,e):
        self.Toggle(0)
    def Toggle(self,i):
        self.count = i
        self.updateFromCount()
    def updateFromCount(self):
        hide_all(self.counts)
        for i in range(self.count+1):
            show_all(self.counts[i])

a = wx.App(redirect=0)
f = mainFrame()
f.Show()
a.MainLoop()

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@乔兰比斯利：@Bair:非常感谢你。我明白它为什么不起作用。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OnB*代码，它只能更改文本。我想创建按钮和不相关的text.SetLabel（OnB1->text.AppendText（'1235535'）。什么？我不明白你在问什么for@Joran比斯利：我的意思是我怎样才能使它正确或有效。不可能吗？？？你能教我一些可以通过几个按钮进行更改的代码吗？非常感谢。你的回答对我很有帮助。我能再问一件事吗？我试图应用我的代码。但是我在self.counts[]中有一些错误（我的问题代码底部有错误代码）。
