我在使用线程和编辑器控件时遇到问题,我无法在编辑器中使用线程进程。例如,我只是简单地将文本添加到带有线程的编辑器控件中,但它发生了错误:
PyAssertionError: C++ assertion "m_buffer && m_buffer->IsOk()" failed at ..\..\include\wx/dcbuffer.h(104) in wxBufferedDC::UnMask(): invalid backing store
这是我的代码:
import threading
import wx
import wx.lib.editor as editor
class RunTest(threading.Thread):
def __init__(self,master,type):
threading.Thread.__init__(self)
self.master = master
self.type = type
def run(self):
if self.type == 1:
for i in range(1000):
self.master.ed.BreakLine(None)
self.master.ed.SingleLineInsert("Text Line Number: " + str(i))
class Test(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, 'Test', size=(900, 700))
win = wx.Panel(self, -1)
self.ed = editor.Editor(win, -1)
box = wx.BoxSizer(wx.VERTICAL)
box.Add(self.ed, 1, wx.ALL|wx.GROW, 1)
win.SetSizer(box)
win.SetAutoLayout(True)
self.ed.Bind(wx.EVT_LEFT_DCLICK, self.OnClick)
def OnClick(self,event):
thread = RunTest(self,1)
thread.start()
if __name__ == '__main__':
app = wx.PySimpleApp()
root = Test()
root.Show()
app.MainLoop()
请帮我修复它。我使用 wx.python 库,python 2.7,在窗口 7 中运行
