Good morning Guru
I need to change the window menu, but something is not working for me.

Let's go in order.


I have a window with a menu I don't know the name of.
When certain conditions occur, I have to change the menu.
In the end I have to restore the original menu (whose name I didn't know)

I tried in the following way, but as you can see from the image as soon as I change the menu with changemenu the saving made goes to null.

=======================================

 

menu m_temp
m_temp = create menu
m_temp = parent.menuid
parent.changemenu(m_genapp_sheet2)
// code here
parent.changemenu(m_temp)

=======================================

 

 

Some idea?

Thanks in advance.
Gimmy

Hi Gimmy;

   Unfortunately, the ChangeMenu() command only accepts an object (class) name and not a string variable with the class name.

   This would be a nice enhancement request IMHO. Say for example:

  • Menu   lo_mu_hold
  • Menu   lo_mu
  • String   ls_mu_old_name
  • String   ls_mu_new_name = "m_gimmy"
  • lo_mu_hold = Parent. menuid
  • ls_mu_old_name = lo_mu_hold.ClassName()
  • ChangeMenu ( ls_mu_new_name, lo_mu, 0 )
  • // processing
  • // ...
  • ChangeMenu ( ls_mu_old_name, lo_mu, 0 )

  Of course, this ChangeMenu() command syntax does not yet exist currently.  :-(

  I would suggest submitting an enhancement request.

Regards ... Chris

yes, as Chris said: ChangeMenu needs a menu object that physically exists in one of your libraries.

Hi Gimmy;

   Thank you for submitting a Support Ticket for this as an enhancement request. It's now on its way to Engineering and Product Management. I added another suggestion (My $0.02 worth) on to that ticket as well for this feature enhancement.  ;-)

HTH

Regards ... Chris

The easiest workaround for this is to create a psarent menu with EVERYTHING on it, and hide the entries that are not normally used on the various inherited menus.

The unknown menu is now a descendant of the full blown parent menu.

Get a pointer to the menu, SHOW the options required, HIDE those no longer needed.

When you restore the "original menu", just reverse what you did in the previous step.
