Hi all,

just a quick one here, never really come across it before. I actually
discovered it using Toolbar2000 but the same behaviour is shown using the
normal TMainMenu vcl.

Basically, I have an application where I have defined a whole set of
TActions for all the different functionality within my app. I have also
defined a global handeller to deteremine which Action should be enabled /
disabled - which I have done using the TActionList->OnUpdate event, setting
the Handled parameter to true, after I have deteremined the necessary
status. Now before the user have login to my system, I want all the
Actions, bar actLogin & actExit, to be disabled, and to the OnUpdate code
mimics this. The behaviour below is show even when I code individual
OnUpdate event for each Action!

Now within my TMainMenu, I have assigned a corisponding Action to all the
menu items, and so they all appear disabled, based on the above senario, all
except the Sub-menu items. I have one Sub-menu that is call "New" and the
corisponding sub-menu contains a list of new items / actions. Because the
Sub-menu item is not assigned an Action, no update processing is done for
it - which is expected. So now I go about coding a "generic new" Action to
be assigned to this sub-menu and deal with disabling the sub-menu until the
user is logon.

When the app is run, the "New Generic" Action is diabled thus the sub-menu
item is disabled and the corisponding sub-menu is not displayed / popped-up.
User logs on, the sub-menu item is enabled, I move my mouse over the
sub-menu item, the sub-menu pops-up but then the sub-menu item becomes
diabled. The sub-menu is displayed but the sub-menu item is disabled, the
OnUpdate code should force it to be enabled but the OnUpdate event is not
called a second time, the menu simply is diabled. I can't understand this
behaviour - the same thing happends with Toolbar2000. Is there some sore of
default behaviour where by a Sub-menu item can't have an Action assigned to
it. Can a TMenuItem can as both a menu item (i.e. the user can click on it
to envoke some function) and a sub-menu item (i.e. to open a sub menu)

I know this isn't 100% clear - I can post the exe / code if anyone wants to
have a look.

Cheers,

Mike
