python - 如何在 Wxpython 中动态创建复选框或按钮？

Question

posx = 50
for name in sheets:
    wx.CheckBox(self, -1 ,name, (15, posx))
    posx = posx + 20

当我执行此操作时，复选框出现但它们不起作用，这意味着我无法选中任何框，动态添加复选框或按钮的正确方法是什么？

我现在已经编辑了我的代码并将其添加到面板中，现在复选框甚至没有出现

pnl = wx.Panel(self)
posx = 50
for name in sheets:
    cb = wx.CheckBox(pnl, label=name, pos=(20, posx))
    cb.SetValue(True)
    cb.Bind(wx.EVT_CHECKBOX, self.doSomething)
    posx = posx + 20

def doSomething(Self,e):
sender = e.GetEventObject()
isChecked = sender.GetValue()

if isChecked:
    #do something here            
else: 
    #do something else here

这行得通。

import wx

class MyApp(wx.App):

  def OnInit(self):
    frame = InsertFrame(parent=None, id=-1)
    frame.Show()
    return True

class InsertFrame(wx.Frame):

  def __init__(self, parent, id):
    wx.Frame.__init__(self, parent, id, 'Test Frame', size = (300,100))
    panel = wx.Panel(self)
    pos_y = 0
    for i in range(50):
      pos_y += 20
      cb = wx.CheckBox(panel, label="sample checkbox", pos=(20, pos_y))

if __name__ == "__main__":
  app = MyApp()
  app.MainLoop()

这只是使用复选框设置小部件。

复选框类-> http://wxpython.org/docs/api/wx.CheckBox-class.html
按钮类-> http://wxpython.org/docs/api/wx.Button-class.html

复选框的示例代码：

  #!/usr/bin/python
 # -*- coding: utf-8 -*-

  import wx


  class Example(wx.Frame):

  def __init__(self, *args, **kw):
  super(Example, self).__init__(*args, **kw) 

  self.InitUI()

  def InitUI(self):   

   pnl = wx.Panel(self)

   cb = wx.CheckBox(pnl, label='Show title', pos=(20, 20))
   cb.SetValue(True)

   cb.Bind(wx.EVT_CHECKBOX, self.ShowOrHideTitle)

   self.SetSize((250, 170))
   self.SetTitle('wx.CheckBox')
   self.Centre()
   self.Show(True)    

def ShowOrHideTitle(self, e):

  sender = e.GetEventObject()
  isChecked = sender.GetValue()

  if isChecked:
    self.SetTitle('wx.CheckBox')            
  else: 
    self.SetTitle('')        

 def main():

 ex = wx.App()
  Example(None)
  ex.MainLoop()    

 if __name__ == '__main__':
 main()

按钮的示例代码：

import wx

class MyFrame(wx.Frame):
   """make a frame, inherits wx.Frame"""

def __init__(self):
   # create a frame, no parent, default to wxID_ANY

 wx.Frame.__init__(self, None, wx.ID_ANY, 'wxButton',

 pos=(300, 150), size=(320, 250))
 self.SetBackgroundColour("green")
 self.button1 = wx.Button(self, id=-1, label='Button1',
 pos=(8, 8), size=(175, 28))
 self.button1.Bind(wx.EVT_BUTTON, self.button1Click)
  # optional tooltip
  self.button1.SetToolTip(wx.ToolTip("click to hide"))

  # show the frame 
   self.Show(True)
    def button1Click(self,event):
    self.button1.Hide()
    self.SetTitle("Button1 clicked")
    self.button2.Show()

    application = wx.PySimpleApp()
    # call class MyFrame
    window = MyFrame()
    # start the event loop
    application.MainLoop()
