嵌入Wx2

如何在具有新工具栏的应用程序中使用wxagg的示例

  1. from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
  2. from matplotlib.backends.backend_wx import NavigationToolbar2Wx as NavigationToolbar
  3. from matplotlib.figure import Figure
  5. import numpy as np
  7. import wx
  8. import wx.lib.mixins.inspection as WIT
  11. class CanvasFrame(wx.Frame):
  12.     def __init__(self):
  13.         wx.Frame.__init__(self, None, -1,
  14.                           'CanvasFrame', size=(550, 350))
  16.         self.figure = Figure()
  17.         self.axes = self.figure.add_subplot(111)
  18.         t = np.arange(0.0, 3.0, 0.01)
  19.         s = np.sin(2 * np.pi * t)
  21.         self.axes.plot(t, s)
  22.         self.canvas = FigureCanvas(self, -1, self.figure)
  24.         self.sizer = wx.BoxSizer(wx.VERTICAL)
  25.         self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.EXPAND)
  26.         self.SetSizer(self.sizer)
  27.         self.Fit()
  29.         self.add_toolbar()  # comment this out for no toolbar
  31.     def add_toolbar(self):
  32.         self.toolbar = NavigationToolbar(self.canvas)
  33.         self.toolbar.Realize()
  34.         # By adding toolbar in sizer, we are able to put it at the bottom
  35.         # of the frame - so appearance is closer to GTK version.
  36.         self.sizer.Add(self.toolbar, 0, wx.LEFT | wx.EXPAND)
  37.         # update the axes menu on the toolbar
  38.         self.toolbar.update()
  41. # alternatively you could use
  42. #class App(wx.App):
  43. class App(WIT.InspectableApp):
  44.     def OnInit(self):
  45.         'Create the main window and insert the custom frame'
  46.         self.Init()
  47.         frame = CanvasFrame()
  48.         frame.Show(True)
  50.         return True
  52. app = App(0)
  53. app.MainLoop()
