+ to specify just the stock ID and leave @a text and @a helpString empty.
+ Some platforms (currently wxGTK only, and see the remark in SetBitmap()
+ documentation) will also show standard bitmaps for stock menu items.
+
+ Leaving at least @a text empty for the stock menu items is actually strongly
recommended as they will have appearance and keyboard interface (including
standard accelerators) familiar to the user.
+
For the custom (non-stock) menu items, @a text must be specified and while
@a helpString may be left empty, it's recommended to pass the item
- description (which is automatically shown by the library in the status bar when
- the menu item is selected) in this parameter.

Finally note that you can e.g. use a stock menu label without using its stock
- help string; that is, stock properties are set independently one from the other.
+ help string:
+
+ @code
+ // use all stock properties:
+ helpMenu->Append(wxID_ABOUT);
+
+ // use the stock label and the stock accelerator but not the stock help string:
+ helpMenu->Append(wxID_ABOUT, "", "My custom help string");
+
+ // use all stock properties except for the bitmap:
+ wxMenuItem *mymenu = new wxMenuItem(helpMenu, wxID_ABOUT);
+ mymenu->SetBitmap(wxArtProvider::GetBitmap(wxART_WARNING));
+ helpMenu->Append(mymenu);
+ @endcode
+
+ that is, stock properties are set independently one from the other.
@param parentMenu

@param text
- Text for the menu item, as shown on the menu. An accelerator

- ampersand character in the menu item text, the ampersand must be doubled.

+
+ The label string for the normal menu items (not separators) may include the

+
+ Optionally you can specify also an accelerator string appending a tab character
+ <tt>\\t</tt> followed by a valid key combination (e.g. <tt>CTRL+V</tt>).
+ Its general syntax is any combination of @c "CTRL", @c "ALT" and @c "SHIFT" strings
+ (case doesn't matter) separated by either @c '-' or @c '+' characters and followed
+ by the accelerator itself.
+ The accelerator may be any alphanumeric character, any function key
+ (from F1 to F12) or one of the special characters listed in the table
+ below (again, case doesn't matter):
+ - @c DEL or @c DELETE: Delete key
+ - @c BACK : Backspace key
+ - @c INS or @c INSERT: Insert key
+ - @c ENTER or @c RETURN: Enter key
+ - @c PGUP: PageUp key

+ - @c LEFT: Left cursor arrow key
+ - @c RIGHT: Right cursor arrow key
+ - @c UP: Up cursor arrow key
+ - @c DOWN: Down cursor arrow key
+ - @c HOME: Home key
+ - @c END: End key
+ - @c SPACE: Space
+ - @c TAB: Tab key
