dynamic menus in applicationframework, ect

[JD Kromkowski]

while using the application framework, I’d like to be able to change menu items. E.g., if I have a new form loaded I may want a menu that is substantially similiar but slightly different than the main menu. I can add new menuitems, but I can’t see how to delete/remove an item. I see, I think, how I could remove a whole menubar and replace it with an entirely new menubar but that doesn’t seem the correct approach, when I just want to remove one or two items. I am not seeing/finding the correct method to handle this. JDK

Actually, there is no method of removing menu items or menus. The MUR library stuff actually clones and inserts a menu or submenu
in a specified place and then replaces the whole menu bar.

OK, not feeling so dumb. So the way to do this is to replace mb with a
new mb.

Replacing whole mb is a bit more complicated that I anticipated. I can
only seem to be able to do it once without the whole mb dissappearing
altogether from the window. I'm sure I am doing something wrong. But
instead:

I added the following to mainmenu()

datamenu.insert("","Employee View",enabled=.false,name= "EmployeeForm")
datamenu.insert("","Daily Record
Form",enabled=.true,name="DailyRecordForm")

The following to initmainmenu(…)

mb!data.menu!EmployeeForm.onselect.function =@ ChangeForms

mb!data.menu!EmployeeForm.onselect.reference =@ app

mb!data.menu!DailyRecordForm.onselect.function =@ ChangeForms

mb!data.menu!DailyRecordForm.onselect.reference =@ app

And then created this function:

function ChangeForms(wxmenuitem me, type (application) app)
appwindow appw
appw =@ getappwindowfromwindow(getmenuitemwindow(me))
if sSecondForm == appw.form.filename
appw.mb!data.menu!EmployeeForm.setenabled(.false)
appw.mb!data.menu!DailyRecordForm.setenabled(.true)
appw.openformdirect(sFirstForm,sAPPMSGTITLE)
else
appw.mb!data.menu!EmployeeForm.setenabled(.true)
appw.mb!data.menu!DailyRecordForm.setenabled(.false)
appw.openformdirect(sSecondForm,sAPPMSGTITLE)
end if
end function

I still don't actually understand why it is "data.menu!" instead of
"datamenu!", but I know what works.
