摘要
一般来说，这是wxPython中一种公认的方法，它直接来自the docs创建新的“数据”事件。
使控制器监听“数据”事件
让按下“开始”按钮启动一个线程，该线程增加一个计数器，并将一个“数据”事件发送到窗口并附加计数器值。
接收到事件后，将值添加到您的RichTextCtrl
示例
这里有一个例子。请特别注意使用Connect()来监听传入的值事件。在import wx
import wx.richtext
import threading
import time
EVT_ID_VALUE = wx.NewId()
class DataEvent(wx.PyEvent):
def __init__(self, data):
wx.PyEvent.__init__(self)
self.SetEventType(EVT_ID_VALUE)
self.data=data
class Frame3(wx.Frame):
def __init__(self, parent, title):
self.counter = 0
self.worker = None
wx.Frame.__init__(
self, name='',
parent=parent,
pos=wx.Point(579, 234),
size=wx.Size(414, 492),
style=wx.DEFAULT_FRAME_STYLE, title='Frame3'
)
self.panel1 = wx.Panel(
name='panel1',
parent=self,
pos=wx.Point(0, 0),
size=wx.Size(406, 458),
style=wx.TAB_TRAVERSAL
)
self.richTextCtrl1 = wx.richtext.RichTextCtrl(
parent=self.panel1,
pos=wx.Point(96, 96),
size=wx.Size(200, 100),
style=wx.richtext.RE_MULTILINE,
value=u''
)
self.richTextCtrl1.SetLabel(u'richText')
self.richTextCtrl1.SetScrollbars(20,20,50,50)
self.button2 = wx.Button(
label=u'STOP',
name='button2',
parent=self.panel1,
pos=wx.Point(256, 280),
size=wx.Size(75, 23),
style=0
)
self.button2.Bind(
wx.EVT_BUTTON,
self.OnStop
)
self.button1 = wx.Button(
label=u'START',
name='button1',
parent=self.panel1,
pos=wx.Point(88, 280),
size=wx.Size(75, 23),
style=0
)
self.button1.Bind(
wx.EVT_BUTTON,
self.OnStart
)
self.Connect(-1, -1, EVT_ID_VALUE, self.OnValue )
def OnValue(self, event):
self.richTextCtrl1.AppendText("%d\n"%event.data)
def OnStart(self, event): #START BUTTON
self.richTextCtrl1.AppendText("START\n")
if not self.worker:
self.worker = WorkerThread(self)
self.worker.start()
def OnStop(self, event): #STOP BUTTON
self.richTextCtrl1.AppendText("STOP\n")
if self.worker:
self.worker.stop()
class WorkerThread(threading.Thread):
def __init__(self, notify_window):
threading.Thread.__init__(self)
self.counter = 0
self._notify_window = notify_window
self.abort = False
def run(self):
while not self.abort:
self.counter += 1
wx.PostEvent(self._notify_window, DataEvent(self.counter))
time.sleep(1)
def stop(self):
self.abort = True
if __name__ == '__main__':
app = wx.App()
frame = Frame3(None, "My Hello App")
frame.Show(True)
app.MainLoop()
