我有2个绘图按钮，它们从同一资源中获取不同的数据。处理大约需要5秒钟。为了能够这次按下第二个按钮，我使用的是 wx.lib.delayedresult 。
在 wx.lib.delayedresult 之前，按第一个按钮--->处理需要5秒钟（在此期间，我无法按第二个按钮）--->结果1。--- >按下第二个按钮---> 5s处理--->结果2。因此，所有过程需要10-11秒。
在 wx.lib.delayedresult 之后，按第一个按钮--->处理需要5s（在此期间，按第二个按钮）--->结果1 ---> 5s --- >结果2.因此，所有过程需要10到11秒。
我想要的是，按第一个按钮---> 5s处理（这次也按第二个按钮）--->结果1和结果2。所有操作都需要5-6秒。
只有通过 wx.lib.delayedresult 才有可能吗？还是我应该使用线程，队列，处理等？
任何建议将不胜感激。
这是wx.lib.delayedresult的一个小例子。
from time import sleep
import wx
from wx.lib.delayedresult import startWorker
class MainWindow(wx.Frame):
def __init__(self, *args, **kwargs):
wx.Frame.__init__(self, *args, **kwargs)
self.panel = wx.Panel(self)
self.startButton = wx.Button(self.panel, label="Long Task")
self.Button1 = wx.Button(self.panel, label="btn1")
self.Button2 = wx.Button(self.panel, label="btn2")
self.startButton.Bind(wx.EVT_BUTTON, self.OnStartButton)
self.Button1.Bind(wx.EVT_BUTTON, self.OnBtn)
self.Button2.Bind(wx.EVT_BUTTON, self.heyBtn)
self.windowSizer = wx.BoxSizer()
self.windowSizer.Add(self.panel, 1, wx.ALL | wx.EXPAND)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.startButton)
self.sizer.Add(self.Button1)
self.sizer.Add(self.Button2)
self.sizer.Add((10, 10))
self.border = wx.BoxSizer()
self.border.Add(self.sizer, 1, wx.ALL | wx.EXPAND, 5)
self.panel.SetSizerAndFit(self.border)
self.SetSizerAndFit(self.windowSizer)
self.Show()
def OnStartButton(self, e):
self.startButton.Disable()
startWorker(self.LongTaskDone, self.LongTask)
def OnBtn(self, e):
hey(self).Show()
def heyBtn(self, event):
self.Button2.Disable()
startWorker(self.LongTaskDone_2, self.LongTask)
def LongTask_2(self):
print("LT 2")
sleep(5)
def LongTaskDone_2(self, result):
self.Button2.Enable()
print("ended 2")
def LongTask(self):
print("LT 1")
sleep(5)
print("hello")
def LongTaskDone(self, result):
print("ended 1")
self.startButton.Enable()
class hey(wx.Frame):
def __init__(self, *args, **kwds):
wx.Frame.__init__(self, *args, **kwds)
app = wx.App(False)
win = MainWindow(None)
app.MainLoop()
以下，LongTask btn处理5s，btn1单独处理5s。全部加在一起将在8-9秒内给出结果。如何在5秒内获得所有结果？
