这个python程序在wxpython窗口中绘制一个图形。它在Enthought Python Distribution 7.3-2中运行良好,但是当我关闭图形时,python继续运行并且不会退出。
我错过了什么?当我创建不使用matplotlib的wxpython GUI时,它会在我关闭窗口后正确退出。我想wxpython中必定存在一些我不理解的消息循环。

self.log("button clicked, id#%d\n", event.GetId())
def drawplot(self, fig):
ax = fig.add_subplot(1,1,1)
t = pl.arange(0,1,0.001)
ax.plot(t,t*t)
ax.grid()
return ax
app = wx.App(False)
frame = wx.Frame(None)
panel = GUIPanel(frame)
frame.Fit()
frame.Center()
frame.Show()
app.MainLoop()
答案 0 :(得分:0)
咦。根据tcaswell的评论中的讨论,我改变了
self.figure = pl.figure()
到
self.figure = matplotlib.figure.Figure()
它解决了这个问题。 (当我关闭窗口时,python退出)
