wxPython – wx.MenuBar 的 GetFrame()函数

在本文中，我们将学习与 wxPython 的 wx.MenuBar 类关联的 GetFrame()函数。 GetFrame()函数用于获取菜单栏的父框架。我们可以操纵框架。
GetFrame()函数中不需要参数

Syntax: wx.MenuBar.GetFrame(self)

Parameters: No parameters are required in GetFrame() function

代码示例 #1：

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)
        self.menubar = wx.MenuBar()
        self.fileMenu = wx.Menu()
  
        self.item = wx.MenuItem(self.fileMenu, 1, '&Check',
                                  helpString ="Check Help")
        self.item.SetBitmap(wx.Bitmap('right.png'))
  
        # SET BLUE COLOUR FOR TEXT FORMAT(R, B, G, A)
        self.item.SetTextColour((79, 81, 230, 255))
        self.fileMenu.Append(self.item)
        self.menubar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menubar)
        self.SetSize((350, 250))
        self.SetTitle('Icons and shortcuts')
        self.Centre()
  
        # GET wx.Frame OBJECT
        frame = self.menubar.GetFrame()
  
        # PRINT TITLE OF frame
        print(frame.GetTitle())
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()

    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
  
        self.InitUI()
  
    def InitUI(self):
  
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH)
        self.menubar = wx.MenuBar()
        self.fileMenu = wx.Menu()
  
        self.item = wx.MenuItem(self.fileMenu, 1, '&Check', 
                                  helpString ="Check Help")
        self.item.SetBitmap(wx.Bitmap('right.png'))
  
        # SET BLUE COLOUR FOR TEXT FORMAT(R, B, G, A)
        self.item.SetTextColour((79, 81, 230, 255))
        self.fileMenu.Append(self.item)
        self.menubar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menubar)
        self.SetSize((350, 250))
  
        # GET wx.Frame OBJECT
        frame = self.menubar.GetFrame()
        # SET NEW TITLE FOR FRAME
        frame.SetTitle('New Frame Title')
        self.Centre()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()

输出：
