如何关闭wxpython打开的窗口？

我先用wxpython打开一个窗口，但等到一定时间后自动关闭这个窗口，该怎么关闭？

import wx
class mywindow(wx.App):
    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,title="窗口",pos=(100,100),size=(500,500)

if __name__=='__main__':
    app=wx.App()
    frame=mywindow(parent=None,id=-1)
    frame.Show()
    app.MainLoop()

就是不明白如何关闭窗口，请大家帮帮忙！感谢！

sleep 休眠几秒
frame .close()

import wx
import threading
import time


class mywindow(wx.App):
    def doClose(self,j):
        time.sleep(j)
        self.frame.Close()
    def __init__(self):
        wx.App.__init__(self)
        self.frame = wx.Frame(parent=None, id=-1, title="窗口", pos=(100, 100), size=(500,500))
        self.frame.Show()
        t =threading.Thread(target=self.doClose,args=(0.5,))
        t.start()
if __name__ == '__main__':
    app = mywindow()
    app.MainLoop()

窗口关闭事件

现在有一个主窗口，然后加了一个TaskBarIcon
第一：我想把主窗口中的关闭事件改成隐藏主窗口，不知道怎么实现，在网上搜了一圈找到了wx.CloseEvent这个好像和close事件有关的。。但是不知道如何操作。。

第二：程序创建了一个Frame和一个TaskBarIcon，但是在关闭的时候有点问题。从Frame的关闭只能销毁Frame本身，而在TaskBarIcon中定义的菜单退出可以销毁所有资源
