我正在尝试在 Tkinter 中使用withdraw()/deiconify() 为我的应用程序进行隐藏/显示,但是在 deiconify() 方法调用后我的应用程序挂起。在 Win7 上运行此代码。我做错了什么?
import Tkinter as tk
import threading
class MyApp(object):
def __init__(self, parent):
self.root = parent
self.root.geometry('400x300')
self.root.title('My Application')
btn = tk.Button(parent, text='Hide', command=self.onClick)
btn.pack()
def onClick(self):
self.hide()
self.t = threading.Timer(3, self.show)
self.t.start()
def hide(self):
print 'hide()'
print 'state: ', self.root.state()
print 'withdraw()'
self.root.withdraw()
print 'state: ', self.root.state()
def show(self):
print 'show()'
print 'state: ', self.root.state()
print 'deiconify()'
self.root.deiconify()
print 'state: ', self.root.state()
print 'show end'
if __name__ == '__main__':
root = tk.Tk()
app = MyApp(root)
root.mainloop()
UPD:有一个工作样本:
import Tkinter as tk
import sched
import time
class MyApp(object):
def __init__(self, parent):
self.root = parent
self.root.geometry('400x300')
btn = tk.Button(parent, text='Hide', command=self.onClick)
btn.pack()
self.scheduler = sched.scheduler(time.time, time.sleep)
def onClick(self):
self.hide()
self.scheduler.enter(3, 1, self.show, ())
self.scheduler.run()
def hide(self):
self.root.withdraw()
def show(self):
self.root.deiconify()
if __name__ == '__main__':
root = tk.Tk()
app = MyApp(root)
root.mainloop()
