wxPython – Add submenu in Menu
In this article we are going to learn How can we add submenu to a Menuitem inside a Menu present on MenuBar. In this we use AppendMenu() function rather than just using Append().
Steps :
1. Create a MenuBar in frame using MenuBar() constructor.
2. Add menu to the menu bar.
3. Create wx.Menu for Menuitem.
4. Add menu using ApendMenu() function.
Syntax :
wx.Menu.AppendMenu(self, id, subMenu, helpString)Parameters of AppendMenu():
Parameter Input Type Description id int The menu item identifier. item string the string to appear on the menu item; subMenu wx.Menu an instance of FlatMenu, the submenu to append, helpString int an optional help string associated with the item. By default, the handler for the EVT_FLAT_MENU_ITEM_MOUSE_OVER event displays this string in the status line.
Code Example:
import wx class Example(wx.Frame): def __init__(self, *args, **kwargs): super(Example, self).__init__(*args, **kwargs) self.InitUI() def InitUI(self): menubar = wx.MenuBar() fileMenu = wx.Menu() # submenu for menuitem imp = wx.Menu() imp.Append(wx.ID_ANY, 'SubMenu 1') imp.Append(wx.ID_ANY, 'SubMenu 2') imp.Append(wx.ID_ANY, 'SubMenu 3') # append submenu with menuitem fileMenu.AppendMenu(wx.ID_ANY, 'MenuItem', imp) menubar.Append(fileMenu, '&Menu') self.SetMenuBar(menubar) self.SetSize((350, 250)) self.SetTitle('Submenu') self.Centre() def OnQuit(self, e): self.Close() def main(): app = wx.App() ex = Example(None) ex.Show() app.MainLoop() if __name__ == '__main__': main() |
