wxWidgets bindings don't respond when a context menu is in order.

patch to add wx port context menus

[Kevin Ollivier]

When I try this patch, I get an assert in ContextMenuItem::ContextMenuItem(ContextMenuItemType type, ContextMenuAction action, const String& title, ContextMenu* subMenu). 

Here's the assert message:

[Debug] 09:57:24: /BUILD/wxPython-src-2.8.8.1/src/common/menucmn.cpp(381): assert "parentMenu != NULL" failed in wxMenuItemBase(): menuitem should have a menu

It's possible that you built in release mode and thus didn't see this assert. To build debug, you can run `WebKitTools/Scripts/set-webkit-configuration --wx --debug`.

In any case, I had to give an r- to this patch because an assert like that usually indicates that on at least one platform, the approach you're trying won't work. I think what we need to do is mimic the GTK and QT ports here, and have a PlatformMenuItemDescription structure that includes a native structure, but the actual wxMenuItem(s) will be created in the ContextMenu::appendItem call. The ContextMenuItem constructors themselves will just store and return the values passed to them inside the PlatformMenuItemDescription struct.

Thanks for all your work on this!

The default constructor for a menu item is NULL, apparently this is a wx bug that has been fixed in later versions:
http://trac.wxwidgets.org/ticket/3425

Request that this be disregarded and patch reconsidered?
