在wxpython中对齐

Question

图库和图框中的复选框正在对齐。在

• 我需要这些复选框在左侧对齐，画布在右侧对齐
• 下面的代码没有正确对齐

有人能建议修改代码吗？在

• 如果我想在同一帧中再添加一个画布，如何添加它？在

  import wx
  import matplotlib.pyplot as plt
  from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
  
  class canvasFrame(wx.Frame):
      def __init__(self,parent,id):
          wx.Frame.__init__(self,parent,id,"MyCanvas",size =(1200,400))
  
          self.fig = plt.Figure(figsize=(15,5))
          self.ax1 = self.fig.add_subplot(1,1,1)
          self.canvas = FigureCanvas(self, -1, self.fig)
  
          b1 = wx.CheckBox(self,-1,"Apples",(10,20),(160,-1))
          b2 = wx.CheckBox(self,-1,"Mango",(10,40),(160,-1))
  
          b1sizer = wx.BoxSizer(wx.VERTICAL)
          b2sizer = wx.BoxSizer(wx.VERTICAL)
          canvSizer = wx.BoxSizer(wx.HORIZONTAL)
  
          b1sizer.Add(b1,0,wx.ALL,5)
          b2sizer.Add(b2,0,wx.ALL,5)
          canvSizer.Add(self.canvas,wx.TOP | wx.EXPAND,5)
  
  if __name__ == "__main__":
     app = wx.App()
     frame = canvasFrame(parent=None,id = -1)
     frame.Show()
     app.MainLoop()

如果您不正确地使用了大小调整器，请尝试以下操作：

import wx
import matplotlib.pyplot as plt
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas

class canvasFrame(wx.Frame):
    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,"MyCanvas",size =(1200,400))

        self.fig = plt.Figure(figsize=(15,5))
        self.ax1 = self.fig.add_subplot(1,1,1)
        self.canvas = FigureCanvas(self, -1, self.fig)

        b1 = wx.CheckBox(self,-1,"Apples", size=(160,-1))
        b2 = wx.CheckBox(self,-1,"Mango", size=(160,-1))

        mainsizer = wx.BoxSizer(wx.HORIZONTAL) # Main sizer
        cbsizer = wx.BoxSizer(wx.VERTICAL) # Checkbox sizer
        canvassizer = wx.BoxSizer(wx.VERTICAL) # Canvas sizer

        # Add checkbox 
        cbsizer.Add(b1, 0, wx.ALIGN_LEFT|wx.ALL, 5)
        cbsizer.Add(b2, 0, wx.ALIGN_LEFT|wx.ALL, 5)

        # Add canvas
        canvassizer.Add(self.canvas, 1, wx.EXPAND|wx.ALL, 1)

        # Add "secondary" sizers to main sizer
        mainsizer.Add(cbsizer, 1, wx.EXPAND|wx.ALL, 2)
        mainsizer.Add(canvassizer, 3, wx.EXPAND|wx.ALL, 2)

        self.SetSizer(mainsizer)


if __name__ == "__main__":
   app = wx.App()
   frame = canvasFrame(parent=None,id = -1)
   frame.Show()
   app.MainLoop()

现在，关于最后一个问题，我认为您应该添加一个子图（轴）而不是其他画布，即

你错过了很多关于尺寸调节器工作原理的部分。。。我真的建议你重新阅读文档并在谷歌上搜索教程

class canvasFrame(wx.Frame):
    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,"MyCanvas",size =(1200,400))

        self.fig = plt.Figure(figsize=(15,5))
        self.ax1 = self.fig.add_subplot(1,1,1)
        self.canvas = FigureCanvas(self, -1, self.fig)

        b1 = wx.CheckBox(self,-1,"Apples",(10,20),(160,-1))
        b2 = wx.CheckBox(self,-1,"Mango",(10,40),(160,-1))
        # first create your sizer for your checkboxes
        checkbox_sizer = wx.BoxSizer(wx.VERTICAL)
        checkbox_sizer.AddMany([b1,b2]) # add both buttons to the sizer
        #next create the main sizer
        main_sizer = wx.BoxSizer(wx.HORIZONTAL)
        #add the checkbox sizer to the main_sizer
        main_sizer.Add(checkbox_sizer)
        # add the canvas to the main sizer
        main_sizer.Add(self.canvas)
        #Set the sizer as the sizer for the frame
        self.SetSizer(main_sizer)
        #call layout for the sizers to layout their elements
        self.Layout()
        #call fit to make the frame fit its contents
        self.Fit()
