在 wxPython 的 MenuBar 类中,GetHelpString() 函数用于获取菜单栏的帮助字符串。它提供了一种简单而灵活的方式来为菜单栏中的每个菜单项添加帮助信息。
GetHelpString(self, id)
import wx
class MyFrame(wx.Frame):
def __init__(self):
super().__init__(None, title='Menu Demo')
menubar = wx.MenuBar()
file_menu = wx.Menu()
file_menu.Append(wx.ID_NEW, '&New', 'Create a new file')
file_menu.Append(wx.ID_OPEN, '&Open', 'Open an existing file')
file_menu.Append(wx.ID_SAVE, '&Save', 'Save the current file')
file_menu.AppendSeparator()
file_menu.Append(wx.ID_EXIT, 'E&xit', 'Exit the application')
menubar.Append(file_menu, '&File')
self.SetMenuBar(menubar)
# 设置菜单项的帮助信息
file_menu.GetHelpString(wx.ID_NEW) # 返回 'Create a new file'
file_menu.GetHelpString(wx.ID_OPEN) # 返回 'Open an existing file'
file_menu.GetHelpString(wx.ID_SAVE) # 返回 'Save the current file'
file_menu.GetHelpString(wx.ID_EXIT) # 返回 'Exit the application'
if __name__ == '__main__':
app = wx.App()
frame = MyFrame()
frame.Show()
app.MainLoop()
返回的代码片段如下所示(markdown格式):
import wx
class MyFrame(wx.Frame):
def __init__(self):
super().__init__(None, title='Menu Demo')
menubar = wx.MenuBar()
file_menu = wx.Menu()
file_menu.Append(wx.ID_NEW, '&New', 'Create a new file')
file_menu.Append(wx.ID_OPEN, '&Open', 'Open an existing file')
file_menu.Append(wx.ID_SAVE, '&Save', 'Save the current file')
file_menu.AppendSeparator()
file_menu.Append(wx.ID_EXIT, 'E&xit', 'Exit the application')
menubar.Append(file_menu, '&File')
self.SetMenuBar(menubar)
# 设置菜单项的帮助信息
file_menu.GetHelpString(wx.ID_NEW) # 返回 'Create a new file'
file_menu.GetHelpString(wx.ID_OPEN) # 返回 'Open an existing file'
file_menu.GetHelpString(wx.ID_SAVE) # 返回 'Save the current file'
file_menu.GetHelpString(wx.ID_EXIT) # 返回 'Exit the application'
if __name__ == '__main__':
app = wx.App()
frame = MyFrame()
frame.Show()
app.MainLoop()
