wxPython - 使用 Destroy()函数销毁按钮小部件

在本文中，我们将学习如何使用 wxPython 的 wx.Button 类中的 Destroy()函数从窗口中销毁按钮小部件。 Destroy()函数用于简单地安全地销毁窗口或小部件。
如果窗口已成功删除，或者已添加到待实际删除的窗口列表中，则 Destroy() 返回 True。

Syntax: wx.StaticText.Destroy(self)

Parameters: Destroy() function takes no arguments.

Return Type: bool

Returns: True if the window has either been successfully deleted, or it has been added to the list of windows pending real deletion.

代码示例：

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 a button at point (20, 50)
        self.btn1 = wx.Button(self.pnl, id = 1, label ="Remove Text", pos =(20, 50))
  
        # create button to destroy
        self.btn0 = wx.Button(self.pnl, id = 1, label ="Click button to remove", pos =(20, 20))
  
        # bind Onclick() function with button
        self.btn1.Bind(wx.EVT_BUTTON, self.Onclick)
  
  
        self.SetSize((350, 250))
        self.SetTitle('wx.Button')
        self.Centre()
  
    def Onclick(self, e):
        # destroy btn0 button
        self.btn0.Destroy()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()

输出窗口：

在销毁（）之前

在销毁（）之后
