This event is generated when a user pulls down a macros menu.

syntaxSyntax:
function OnMenuUpdateCommand(cmd)

Parameters

Parameter Description
cmd An object DlxCommand.

Remarks

When a user pulls down a macro menu, each menu item needs to know whether it should be displayed as enabled or disabled. The target of a menu command provides this information by implementing an handler for this event.

When the menu is pulled down, each handler calls DlxCommand member functions such as Enable and SetCheck, and the menu then appropriately displays each menu item.
