在长时间拍摄功能中,我正在努力使用wxPython和动画(gif)启动画面。到目前为止,我有:
class Splash(wx.SplashScreen):
def __init__(self, parent=None, id=-1):
image = "spinner.gif"
aBitmap = wx.Image(name =image).ConvertToBitmap()
splashStyle = wx.SPLASH_CENTRE_ON_PARENT
splashDuration = 0 # milliseconds
wx.SplashScreen.__init__(self, aBitmap, splashStyle,
splashDuration, parent)
gif = wx.animate.GIFAnimationCtrl(self, id, image,)
self.Show()
self.gif = gif
def Run(self,):
self.gif.Play()
我想做点什么:
splash = Splash()
splash.Run()
result = very_time_consuming_function()
splash.Close()
...
use the result
任何输入都将受到赞赏

您应该在另一个线程上执行耗时的工作,否则GUI将阻止而不响应。
这是一个片段:
import wx
import wx.animate
from threading import Thread
import time
def wrap_very_time_consuming_function():
print "sleeping"
time.sleep(5) # very time consuming function
print "waking up"
wx.CallAfter(splash.gif.Stop)
return 0
app = wx.App()
splash = Splash()
splash.Run()
Thread(target=wrap_very_time_consuming_function).start()
app.MainLoop()
