python - 为什么我不能在 wxPython 中销毁我的 StaticText？

Question

我试图从列表中删除静态文本，但收到错误:AttributeError:“tuple”对象没有属性“Destroy”。我似乎无法找到解决办法。我的代码:

import wx
class oranges(wx.Frame):



    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Testing',size=(300,300))
        self.frame=wx.Panel(self)
        subtract=wx.Button(self.frame,label='-',pos=(80,200),size=(30,30))
        self.Bind(wx.EVT_BUTTON,self.sub,subtract)
        self.trying=[]
        self.something=0
    def sub(self,event):
        for i in zip(self.trying):
            i.Destroy()
        self.something += 1
        self.trying.append(wx.StaticText(self.frame,-1,str(self.something),pos=(200,200)))
        self.trying.append(wx.StaticText(self.frame,-1,str(self.something),pos=(250,200)))


if __name__ =='__main__':
    app = wx.PySimpleApp()
    window = oranges(parent=None,id=-1)
    window.Show()
    app.MainLoop()

我真的很困惑为什么 StaticText 位于元组中。非常感谢!期待答案!

您只需要for i in self.trying:。

但是如果你销毁了StringText，你也必须将它从列表self.trying中删除。

def sub(self,event):

    for i in self.trying:
        i.Destroy()
    self.trying = [] # remove all StaticText from list

    self.something += 1
    self.trying.append(wx.StaticText(self.frame,-1,str(self.something),pos=(200,200)))
    self.trying.append(wx.StaticText(self.frame,-1,str(self.something),pos=(250,200)))

是否必须销毁并再次创建StaticText？
您不能使用 SetLabel 更改 StaticText 中的文本吗？

import wx
class oranges(wx.Frame):

    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Testing',size=(300,300))
        self.frame=wx.Panel(self)
        subtract=wx.Button(self.frame,label='-',pos=(80,200),size=(30,30))
        self.Bind(wx.EVT_BUTTON,self.sub,subtract)

        self.trying=[]
        self.trying.append(wx.StaticText(self.frame,-1,'',pos=(200,200)))
        self.trying.append(wx.StaticText(self.frame,-1,'',pos=(250,200)))

        self.something=0

    def sub(self,event):
        self.something += 1
        for i in self.trying:
            i.SetLabel(str(self.something))            

if __name__ =='__main__':
    app = wx.PySimpleApp()
    window = oranges(parent=None,id=-1)
    window.Show()
    app.MainLoop()
