Question

我正在尝试从列表中删除statictext，我收到错误：AttributeError: 'tuple' object has no attribute '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在一个元组中。非常感谢提前！期待着答案！

您只需要for i in self.trying:。

但如果您销毁StringText，则必须将其从列表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)))

你是否必须再次销毁并创建StaticText？您无法使用StaticText更改SetLabel中的文字吗？

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()

为什么我不能在wxPython中销毁我的StaticText？
