我对这段代码有疑问:
import wx
class Example(wx.Frame):
def __init__(self, *args, **kwargs):
super(Example, self).__init__(*args, **kwargs)
self.InitUI()
def InitUI(self):
toolbar = self.CreateToolBar()
qtool = toolbar.AddLabelTool(wx.ID_ANY, 'Quit', wx.Bitmap('texit.png'))
toolbar.Realize()
self.Bind(wx.EVT_TOOL, self.OnQuit, qtool)
self.SetSize((250, 200))
self.SetTitle('Simple toolbar')
self.Centre()
self.Show(True)
def OnQuit(self, e):
self.Close()
def main():
ex = wx.App()
Example(None)
ex.MainLoop()
if __name__ == '__main__':
main()
当我运行它时,我得到:
Traceback (most recent call last):
File "...\maintest.py", line 34, in <module>
main()
File "...\painter3D\maintest.py", line 29, in main
Example(None)
File "...\maintest.py", line 8, in __init__
self.InitUI()
File "...\maintest.py", line 14, in InitUI
toolbar.Realize()
File "C:\Python27\lib\site-packages\wx-2.9.4-msw\wx\_controls.py", line 3797, in Realize
return _controls_.ToolBarBase_Realize(*args, **kwargs)
wx._core.PyAssertionError: C++ assertion "Assert failure" failed at ..\..\src\msw\toolbar.cpp(796) in wxToolBar::Realize(): invalid tool button bitmap
我用:
Win7
Python2.7
wxPython2.8 unicode
我将不胜感激。
