addAndGetMenuItem is suprisingly slow #166
Description
I was profiling to figure out why an operation in my code was slow, and it turned out that it wasn't at all--it was that I was updating a few menus with the result of the operation. Apparently down inside addAndGetMenuItem in my app there are 32454 calls to getMenuItemByIndex'. I do have a lot of stuff in my menus [I generate them based on what's in my database, so that you can select from any defined item]; it looks like I have somewhere north of 8000 of them, though far less than 32K. Here I'm updating a submenu with about a dozen entries by clearing it, putting back the standard items, and adding a new one to represent a newly-created object. What's the fast way to do this, or can addAndGetMenuItem be sped up?
The reason I'm using addAndGetMenuItem is to have a handle to the menu item [a toggle button] so that I can call "set" on it if it's the active item. If I could just add it with some flag that makes it set, I'd do that instead, but I don't see a flag for that. Perhaps I'm missing something?
