我可以使用wxpython使用迭代创建大量按钮吗？

Question

import wx

class MainFream(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None,title='test', size=(505,500), style=wx.DEFAULT_FRAME_STYLE)
        self.MainPanel = wx.Panel(self)

        test = []

        for i in range(1,11):
            test.append(i)

        print(test)

        self.button1 = wx.Button(self.MainPanel, label=str(test[0]), pos=(0, 0))
        self.button2 = wx.Button(self.MainPanel, label=str(test[1]), pos=(100, 0))
        self.button3 = wx.Button(self.MainPanel, label=str(test[2]), pos=(200, 0))
        self.button4 = wx.Button(self.MainPanel, label=str(test[3]), pos=(300, 0))
        self.button5 = wx.Button(self.MainPanel, label=str(test[4]), pos=(400, 0))
        self.button6 = wx.Button(self.MainPanel, label=str(test[5]), pos=(0, 50))
        self.button7 = wx.Button(self.MainPanel, label=str(test[6]), pos=(100, 50))
        self.button8 = wx.Button(self.MainPanel, label=str(test[7]), pos=(200, 50))
        self.button9 = wx.Button(self.MainPanel, label=str(test[8]), pos=(300, 50))
        self.button10 = wx.Button(self.MainPanel, label=str(test[9]), pos=(400, 50))
        self.button11 = wx.Button(self.MainPanel, label='...', pos=(0, 100))
        self.button12 = wx.Button(self.MainPanel, label='...', pos=(100, 100))
        self.button13 = wx.Button(self.MainPanel, label='...', pos=(200, 100))
        self.button14 = wx.Button(self.MainPanel, label='...', pos=(300, 100))
        self.button15 = wx.Button(self.MainPanel, label='...', pos=(400, 100))

if __name__ == '__main__':
    app = wx.App()
    fream = MainFream()
    fream.Show()
    app.MainLoop()

我想制作多个wx.button。问题是我想根据循环的值创建一个按钮，并为生成的按钮标签赋值。我想知道如何有效地创造这个。

我是否必须逐个创建wx.button变量，就像我上传的代码一样？或者我想知道我是否可以将它变成循环。

诀窍不仅仅是创建大量按钮，而是让它们也可用 如果点击它们，你必须能够识别它们 你还必须能够定位它们 以one的方式可以做到这一点 我使用sizer放置它们并为每个按钮分配一个wx.NewId标识。

import wx

class MainFream(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None,title='test', size=(505,500), style=wx.DEFAULT_FRAME_STYLE)
        self.MainPanel = wx.Panel(self)

        test = []
        button_id = []
        for i in range(1,21):
            test.append(i)
            button_id.append(wx.NewId())

        self.button = []
        for i in range(len(test)):
            self.button.append(wx.Button(self.MainPanel,button_id[i],label=(str(test[i]))))
            self.button[i].Bind(wx.EVT_BUTTON, self.OnButton)

        sizer = wx.FlexGridSizer(0, 5, 5, 5)
        for i in self.button:
            sizer.Add(i, 0, wx.ALL, 0)
        self.MainPanel.SetSizer(sizer)

    def OnButton(self, event):
        Id = event.GetId()
        Obj = event.GetEventObject()
        print ("Button Id",Id)
        print ("Button Pressed:",Obj.GetLabelText())

if __name__ == '__main__':
    app = wx.App()
    fream = MainFream()
    fream.Show()
    app.MainLoop()
