Question

当用户在其他窗口上单击“确定”时，我无法尝试刷新静态文本。当用户从不同的窗口添加内容时，我需要刷新主窗口。代码：

import wx
import random
class oranges(wx.Frame):

    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Testing Sample',size=(1024,768))
        self.frame=wx.Panel(self)
        self.static_text=wx.StaticText(self.frame,-1,str(random.randint(1,100)),pos=(500,500))
        re_button=wx.Button(self.frame,label='Refresh',pos=(200,200),size=(50,50))
        self.Bind(wx.EVT_BUTTON,self.refresh,re_button)
        re_buttoned=wx.Button(self.frame,label='ok',pos=(100,100),size=(50,50))
        self.Bind(wx.EVT_BUTTON,self.another_thing,re_buttoned)
    def refresh(self,event):
        self.static_text.Destroy()
        ra_again=random.randint(1,100)
        self.static_text=wx.StaticText(self.frame,-1,str(ra_again),pos=(500,500))
    def another_thing(self,event):
        class apples(wx.Frame):
            def __init__(self,parent,id):
                wx.Frame.__init__(self,parent,id,'Testing Different sample',size=(1024,768))
                self.frames=wx.Panel(self)
                self.static_text.Destroy()
                ra_again=random.randint(1,100)
                self.static_text=wx.StaticText(self.frame,-1,str(ra_again),pos=(500,500))
        if __name__ =='__main__':
            apps = wx.PySimpleApp()
            windows = apples(parent=None,id=-1)
            windows.Show()
            apps.MainLoop()
if __name__ =='__main__':
    app = wx.PySimpleApp()
    window = oranges(parent=None,id=-1)
    window.Show()
    app.MainLoop()

按下按钮时出现此错误：AttributeError：'apples' object has no attribute 'static_text'。对不起凌乱的代码，因为这只是为了表明问题所在。提前谢谢！期待着答案！

你可以做到

def another_thing(self,event):
    class apples(wx.Frame):
        def __init__(self,parent,id):
            wx.Frame.__init__(self,parent,id,'Testing Different sample',size=(1024,768))
            self.frames=wx.Panel(self)
            window.static_text.Destroy()
            ra_again=random.randint(1,100)

因为你没有在该函数中分配窗口python发现它在本地范围外部并查找全局命名空间匹配（可能是非本地/非全局命名空间？）

所有这一切都说我很难用这个好的用例...你应该尽量避免使用这种类型的代码而不是破解它...

如何刷新wxPython中不合格的wx.StaticText？
