EXAMPLE: Basic Menu Functionality

[Desmond]

Hello,

This example illustrates how to perform basic tasks with the menu bar in any AutoPlay Media Studio 6.0 application.

Skills Used: Enable and Disable items, Menu Bar, Functions, On Menu event, Menu ID's, Tables.

Great example, Desmond!

A couple questions:

What syntax should be used for sub-sub menus?

Is there an efficient way to change the state of a given menu item with an OnMenu event and populating the menu bar through the Project>Menu Bar dialog?

[Desmond]

Thanks!

For sub-sub menu's, just expand the table logic:

-- Initialize sub sub item tables
tMenu[1].SubMenu[1].SubMenu = {}

-- Create sub sub menu
tMenu[1].SubMenu[1].SubMenu[1] = {ID = 1011, Text = "Sub Sub Item 1", Enabled = true, Checked = false};

As for your second question . . . there's no *quick* way that I know of. But the steps would be:

1. Use Application.GetMenu to retrieve the current menu structure
2. Loop through the table (either recursiively or not) looking for the ID you want to enable/disable
3. Enable/Disable it
4. Use Application.SetMenu to write out the modified table

Hope that helps!

Does anyone else have any different menu-interaction techniques that'd be of interest?

Hello,

I've just posted an example function to this forum:

That should allow you to change the properties of an item you create through the Project > Menu Bar dialog, using just it's ID.

I'm a chinese AMS user, and for recent days I'm have been puzzled by the menu item state with the built-in function--"g_OnUpdateMenuEnabled (number CommandID, table ItemInfo)".
Thanks to your guilding example, I think I can handle it smoothly later on, but what the function above is used for?
