What is a wxmenu item?

A menu item represents an item in a menu. Note that you usually don’t have to deal with it directly as wxMenu methods usually construct an object of this class for you. Also please note that the methods related to fonts and bitmaps are currently only implemented for Windows, Mac and GTK+.

What is a wxevt_menu event?

Process a wxEVT_MENU command, which is generated by a range of menu items. This type of event is sent as wxCommandEvent. A menu is about to be opened. On Windows, this is only sent once for each navigation of the menubar (up until all menus have closed).

What is the wxmenuitem equivalent to setbitmaps ()?

It is equivalent to wxMenuItem::SetBitmaps (bmp, wxNullBitmap) if checked is true (default value) or SetBitmaps (wxNullBitmap, bmp) otherwise. SetBitmap () must be called before the item is appended to the menu, i.e. appending the item without a bitmap and setting one later is not guaranteed to work.

How to show bitmap for stock menu items in wxGTK?

For the standard menu items (such as commands to open a file, exit the program and so on, see Stock Items for the full list) it is enough to specify just the stock ID and leave text and helpString empty. Some platforms (currently wxGTK only, and see the remark in SetBitmap () documentation) will also show standard bitmaps for stock menu items.
