Question

I m developing a GUI using wxPython (Boa Constructor IDE). My GUI has the following:

Rich text control
Start button
Stop Button

我的要求是,当我发布《裁武条约》季刊时,数字(1、2、3等)应开始在文字控制中印刷;当我发布《STOP》季刊时,应停止印刷。《刑法》和《两性平等法》都显示了这一点。为满足我的要求,我需要作哪些改动?

Summary

总的来说,这是在WxPython这样做的一种公认方式,直接来自。页: 1

创建新的“数据”活动。
让你的控制者聆听“数据”活动
Let pressing the "Start" button start a thread that increments a counter and sends a "data" event to your window with the counter value attached.
收到这项活动后,将贵条码增值。 RichTextCtrl

Example

这里就是一个例子。特别注意到<代码>Connect()用于聆听即将举办的价值活动。

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),

      value=u  
    )
    self.richTextCtrl1.SetLabel(u richText )

    )
    self.Connect(-1, -1, EVT_ID_VALUE, self.OnValue )

  def OnValue(self, event):
    self.richTextCtrl1.AppendText("%d

  def OnStart(self, event):  #START BUTTON
    self.richTextCtrl1.AppendText("START

    if not self.worker:
      self.worker = WorkerThread(self)
      self.worker.start() 

  def OnStop(self, event):  #STOP BUTTON

    if self.worker:
      self.worker.stop() 


class WorkerThread(threading.Thread):

  def run(self):
    while not self.abort:
      self.counter += 1

  def stop(self):
      self.abort = True



if __name__ ==  __main__ :
    app = wx.App()
    frame = Frame3(None, "My Hello App")
    frame.Show(True)
    app.MainLoop()

既然如此简单,我就只能用一个轴心。时间长,而不是直线。参看。

如果你真的想要使用透镜,那么你很可能要读一下:
