wxPython – 删除点击按钮上的静态文本

在本文中，我们将了解如何在单击同一框架中存在的按钮时从框架中删除静态文本。
我们需要遵循一些步骤：

Step 1: Create a static text in frame.
Step 1: Create a button in the same frame.
Step 1: Assign event function for the button.
Step 4: Destroy static text using Destroy() function.

Syntax: wx.StaticText.Destroy(self)

Parameters: Destroy() function takes no arguments.

代码：

import wx
  
  
class Example(wx.Frame):
  
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
        self.InitUI()
  
    def InitUI(self):
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH)
          
        # create parent panel
        self.pnl = wx.Panel(self)
  
        # create statictext at point (20, 20)
        self.st = wx.StaticText(self.pnl, id = 1, 
                    label ="Click button to remove", pos =(20, 20))
          
        # create button
        self.btn = wx.Button(self.pnl, id = 1, label ="Remove Text", pos =(20, 50))
          
        # bind Onclick() event function
        self.btn.Bind(wx.EVT_BUTTON, self.Onclick)
  
  
        self.SetSize((350, 250))
        self.SetTitle('wx.Button')
        self.Centre()
  
    def Onclick(self, e):
        # destroy static text
        self.st.Destroy()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()
