wxpython:窗口关闭时应用程序不退出 [英] wxpython: app not exiting when window is closed
问题描述
关闭我的应用程序的主窗口后,我的应用程序没有退出主循环.关闭窗口后为什么不打印完成"?
My app is not exiting mainloop after closing my application's main window. why is it not printing "finished" after I close the window?
这是我的代码:
import wx
import numpy as np
import matplotlib
matplotlib.use('WXAgg')
import matplotlib.pyplot as plt
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
class GraphFrame(wx.Frame):
def __init__(self):
self.displaySize = wx.DisplaySize()
wx.Frame.__init__(self, None, -1,
style = wx.DEFAULT_FRAME_STYLE,
size = (self.displaySize[0], self.displaySize[1]))
self.threshold = 3000
self.create_main_panel()
self.draw_plot()
def create_main_panel(self):
self.panel = wx.Panel(self,-1, style = wx.SUNKEN_BORDER)
self.fig = plt.figure()
self.canvas = FigureCanvas(self.panel, -1, self.fig)
self.panelsizer = wx.BoxSizer(wx.HORIZONTAL)
self.panelsizer.Add(self.canvas, 1, wx.EXPAND)
self.panel.SetSizer(self.panelsizer)
mainsizer = wx.BoxSizer(wx.VERTICAL)
mainsizer.Add(self.panel, 1, wx.EXPAND )
self.SetSizerAndFit(mainsizer)
self.init_plot()
def init_plot(self):
self.axes = self.fig.add_subplot(111)
self.axes.set_axis_bgcolor('white')
self.axes.set_title('TITLE', size=12)
self.data = ['2000','2869','4694','2356','3600','1500']
self.xmin = 0
self.xmax = len(self.data)
def draw_plot(self):
self.plot_data = self.axes.plot(
self.data,
linewidth=3,
label = "plot1",
marker = "o",
markersize =7,
)[0]
self.plot_data.set_xdata(np.arange(len(self.data)))
self.plot_data.set_ydata(np.array(self.data))
thresholdplot = self.axes.plot([self.xmin,self.xmax], [self.threshold,self.threshold],"r--",label = "threshold",linewidth = 1)
lg=self.axes.legend(loc="upper left", bbox_to_anchor=(1,1),ncol=1)
self.canvas.draw()
if __name__ == "__main__":
app = wx.PySimpleApp()
app.frame = GraphFrame()
app.frame.Show()
app.MainLoop()
print "Finished"
我需要单独处理关闭事件吗?我尝试处理EVT_CLOSE事件以破坏主机.但是仍然没有任何反应.
Do I need to handle the close event separately? I tried handling the EVT_CLOSE event to destroy the main frame. But still nothing happens.
我在Windows 7上将wx 3.0与python 2.7一起使用
Iam using wx 3.0 with python 2.7 on windows 7
推荐答案
你调用了 matplotlib.pyplot
的恶魔,它有自己的事件循环.
You invoked the demons of matplotlib.pyplot
which has its own eventloop.
我无法向您解释为什么它确实不起作用,但是您可以按以下方法解决它:
I can not explain to you why exactly it does not work, but you can resolve it as follows:
除了编写简单的脚本外,还可以使用 matplotlib 的完全面向对象的接口(请参阅 matplotlib
上的 wxPython
示例).
Use the fully object-oriented interface of matplotlib when doing more than writing simple scripts (see the wxPython
examples on matplotlib
).
可以这样做:
#import matplotlib.pyplot as plt
from matplotlib.figure import Figure
下方:
self.fig = Figure() # instead of plt.figure()
