我是 Python 编程的初学者,现在我想知道为什么我的小部件不能重复显示数字。也就是说,我想让文本显示从 1 到 9 的数字,但在 while 循环中,它只显示 9.... 有什么建议吗?
这是我的代码(Python 版本:2.6):
#!/user/bin/python
import wx
class Frame(wx.Frame):
def __init__(self,parent,id):
wx.Frame.__init__(self, parent, id,
'Show Number',
size = (200,150),
style=wx.MINIMIZE_BOX | wx.RESIZE_BORDER
| wx.SYSTEM_MENU | wx.CAPTION | wx.CLOSE_BOX)
self.initUI()
def initUI(self):
widgetPanel=wx.Panel(self, -1)
widgetPanel.SetBackgroundColour('white')
# Buttons for play the simulation
playButton = wx.Button(widgetPanel, -1, "Play", pos=(10,10), size=(30,30))
self.Bind(wx.EVT_BUTTON, self.play, playButton)
playButton.SetDefault()
# Time
self.timeText = wx.TextCtrl(widgetPanel, -1, "", pos=(10, 50),
size =(100,30), style=wx.TE_CENTER)
self.timeText.SetBackgroundColour('white')
self.timeText.SetFont(wx.Font(20, wx.DECORATIVE, wx.NORMAL, wx.NORMAL))
def play(self, event):
#self.timeText.SetValue("19:32")
self.show_num()
def show_num(self):
x = 0
while(x < 10):
self.timeText.SetValue(str(x))
x += 1
if __name__ == "__main__":
app = wx.App(False)
frame = Frame(parent=None,id=-1)
frame.Show()
app.MainLoop()
